DIY Micro USB to PDMI adapter - Streak 5 Accessories

I just wanted to share what I'd done for my streak in order to quit carrying a cable around everywhere. This is just a quick outline of what I did and supplies I used to make it.
Disclaimer:I am in no way responsible for your warranty getting void, phone blowing up starting ww3 or any other faults that may be the result of attempting this
Parts list:
1x streak usb cable
http://www.ebay.com/itm/16065922734...NX:IT&_trksid=p3984.m1497.l2649#ht_500wt_1286
1x micro usb to mini usb adapter
http://www.ebay.com/itm/25098693990...X:IT&_trksid=p3984.m1497.l2649#ht_3016wt_1035
1x old dvd case
5 minute epoxy
Optional:
small piece of carbon fiber vinyl
what to do:
-cut micro usb out of its rubber/plastic shell
-desolder all the wires
-cut the streak cable close to pdmi connector
-refer to this site for usb diagram, make sure to note that there's one pin that gets skipped over on the micro usb adapter
http://pinouts.ru/SerialPortsCables/usb_cable_pinout.shtml
-solder wires accordingly refer to my pictures if you get lost (the pdmi cable comes with all the wires correctly color coded)
-plug into streak and see if it works
-if everything works proceed to make a plastic shell for it out of dvd case
-use a little bit of epoxy to mount everything and keep it from sliding around
end result should look something like this

Hi I'm not trying to negate the value of your guide in any way. I think a permanent mod to a compatible connection makes a lot of sense, especially if one never plans on using a Dell Streak 7 dock. However, if you're not that motivated and or aren't willing to brick your device this is a great $8 solution: http://www.ebay.com/itm/140853176551?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649.

The cable you linked to wouldn't work, because the jack on the non-PDMI end is a USB A female connector, which accepts the end of the USB cable (USB A male) that normally plugs into the laptop or PC itself. To make it as useful as the DIY adapter the OP mentioned would require you to dismantle the host adapter and replace the USB A female jack with a MicroUSB B female jack.

PDMI connector to mini usb connector
Hello man. My name is Mario. I come from Italy. I'm a psychologist,but on the spare time I like to play with linux & mobile & tablet & technology in general. I was searching for a OTG adapter that was able to recharge my nexus 10 and at the same time that accepts an external sd card and someone has suggests this to me :
eKit 4 in 1 Data Sync Connection Kit For Samsung Galaxy Tab 2 10.1 & Note 10.1
you can read the full story here :
http://android.stackexchange.com/que...-the-same-time
the problem is that I haven't read very well what he says and I haven't understood that it is not good for the nexus 10. For this reason I have tried to search a way to convert the PDMI connector to a mini usb connector and I have found this thread. I would like to ask you if I can make the same thing that you have done and if you can tell me which electric modification I have to make to the board of this connector to convert it as a mini usb connector. Thanks.

T-Mobile Wing: Sync, Power, Audio Cable

I received a Wing from T-Mobile yesterday and the device shipped with standard USB Mini connector (for sync/power) (rectangle with flared bottom) and a wall charger with the same typical mini USB connector. However, the connector on the phone is a similar rectangle shape, but has one diagonal corner, otherwise a perfect rectangle (while also some sort of mini USB connector, this connector is capable of handling audio in addition to sync and power...) It is the same jack that the headphones/mic fit into
In order to make this work, HTC packaged a small 1x1 node with a pigtail to convert the traditional flared mini USB connector to the new format connector.
Does anyone know where such a part might be able to be purchased? Or what the "name" of the connector is that I am describing? T-Mobile and HTC have both been rather useless and arrogant about the subject.
Thanks,

http://www.hot-wire-telekom.de/index.php?aktion=detail&suche=HTC TyTN&asuche=HW132233
Don´t know exactly what you mean? I´m using several USB cables and they all work.
If you want an adapter to use two usb (charge AND headset) HTC himselfe has one. And if you want an usb --> 2,5mm there are several on ebay.
FYI ... the new HTC USB connector is actually a standard Mini-USB with extra pins for analog audio. If you were to take your standard USB cable and plus it into the phone, it should work. The only thing you need the adapter for is to use the headset, which is unfortunate. All the adapter does is split off the USB signal from the audio signal.
At least, this is how I understand it. My Wing won't be here until Tuesday.
In the USA, the Wing ships with a 2-way splitter. One plug is for USB POWER, and the other for headset. Err... I don't know which, if either, DATA would go over, it's mainly intended for use in the car when you want to have it plugged in but use the headset also!
I need to order a smaller audio-converter... something that can go inline with my headphones without looking/feeling/being stupid-big.

I ordered a converted from usb to 2.5mm from igonemobile for use on my Dash and my Wing. It's about 4 inches long, not too big in my opinion.
So far so good. 10 bucks, shipping included.

Fast-charging/USB-charging with micro-USB

Does somebody know yet if this device needs pin4 and pin5 connected (ground) for fast-charging on micro-usb?
On my kaiser I needed to connect these two to be able to charge in my car with my standard USB-charger.
To keep this charger as a universal charger (hope its 2 Amperes won't fry my HD2), I need to buy new cables or a mini-usb to micro-usb adapter and might need to modify them.
I noticed that the battery on my kaiser was getting fairly hot on this 2amps. Is there a protecting circuit, or is this in a safe range for those batteries?
amperes of you charger are max current, wchich you cat have from the charger... it is all about, how much leo will take it is about voltage...
and sorry, no idea about this connectivity... if you will tell me, how to check this, i will check it for you...
So, if I understood correctly, the device determines how much Amps to be drawn?
If you take the wall-charger and you look onto the micro-usb plug:
Code:
_____________
\ , , , , , /
\_________/
PIN: 5 4 3 2 1
For a Kaiser device to fastcharge , pin 5 and 4 must be connected together.
On normal USB-cables (micro and mini) for data, pin4 has no function, it isn't even wired in the cable.
Do you have a volt-meter to check this?
Thanks!
USB A male to micro USB A male cable versus USB B cable?
Hello guys,
I bought my HD2 yesterday ! I am very happy with it.
I would like to buy 2 more cables on ebay (1 for the office, 1 for home).
Should I buy the
- USB A male to micro USB A male cable
OR
- USB A male to micro USB B male cable
I am a bit confused here.
I see 2 types of cables on ebay, not sure which one to buy!
Any ideas?
Thanks
If my assumptions are correct, and the cables work like on the Kaiser device, it's:
- USB A male to micro USB A male cable (for fast-charging, works with generic-usb car charger - NO data connection)
edit: WRONG, because micro-A-plug is not compatible with micro-B-socket.
- USB A male to micro USB B male cable (for data-connection and slow USB-charging)
Still needs confirmation by an HD2-user, but I don't think HTC changed something going from mini to micro-plug. (I think they dropped EXT-usb design for having an extra 3,5mm headset-jack instead. - but that shouldn't confuse you)
Well, not exactly:
Type A is to be plugged into host-device (the one supplying power to the other device, usually the charger or your computer), whereas type B is to be plugged into the target device (in this case, the HD2).
This typology exists to prevent you from linking two power suppliers at both ends of the cable...
So what you need is a "USB Type A to Micro USB Type B" cable
That's the original USB-specs, you are referring to.
Mini/micro-A-plugs are using pin4-to-ground by these USB-spec, for electronically differenciating these.
What I wanted to pinpoint, is that HTC decided to mark pin4-to-ground for detection of their charging equipment.
And since micro-A plugs fit into micro-B sockets, you should be able to use a "USB A male to micro USB A male cable" for your charging needs (without modifying your micro-B cable, which can be quite tricky because of its size)
edit: I was wrong with that, it's the other way round, sry. Does the HD2 have a AB-socket then? I believe it's a regular B-socket.
Then if I stand correctly, you will still need a special modified micro-B-cable for charging.
To make it even more difficult, HTC-design does not charge the Kaiser with a regular mini-b-cable on a car-charger, because there was no data-signal on it.
My intention of this thread was asking, if this behavior has changed when going from mini to micro-usb design, and is still an unanswered question.

Well, I've seen unboxing videos now, and the wall-charger ... is a normal-USB-plug-in device like a car-charger. Seems that my intention of this thread is obsolete.

How to use USB Host without an HD Dock (Updated 11/7/12)

In light of the EOL status of the Bionic, this method may no longer be the most cost effective, as the HD dock is now $24 on Amazon, before shipping. Still, this is a cheap way to use usb devices away from a tv or monitor. Please keep all of this in mind before considering this option.
Many Bionic users have wondered if they could somehow use USB host without having to buy an expensive dock. Well, I have just finished testing a method that works. Now please note it's not the sleekest or most portable of methods. Still, it works.
Test Build - http://img.photobucket.com/albums/v148/silversonic1/GEDC0056.jpg
You may be wondering why I am using a Y USB cable. In my testing, I have come to the conclusion that Motorola intentionally crippled the phone's OTG functions. It appears that the host mode only works when TWO priorities are met. First, the phone MUST be receiving power. Second, a hub MUST be used. If either of these is not met, the OTG mode stays offline.
Because this method requires extra power, you have to have a powered USB port nearby. Some USB power packs may put out enough power, but it's still uncertain. However, since my Scosche solar battery pack worked both for the Bionic alone and for this build, it could be possible that anything that works for the Bionic will work for the build as well. Also, I have no way of testing this in a car at the moment.
Action Shot - http://img.photobucket.com/albums/v148/silversonic1/GEDC0052-1.jpg
In the action shot, I am testing a 4GB SanDisk Cruzer. I did run other tests and usb keyboards and mice will work. I used a wireless Targus mouse, as well as a wireless HP mouse and keyboard. They all worked. Sadly, that is the extent of my current HID tech at the moment.
One thing I have observed in my tests is that you should have all of your rig connected before hooking it up to your phone. That includes external power. Not doing so could cause your hub to be recognized much more slowly, or not at all.
I would also like to note that although many hubs allow for AC/DC power adapters to be used, most hubs won't send power through the host port. That is why the Y cable is necessary. But don't worry! I believe that if you attach the power connector of the Y cable to one of the ports of your powered hub, this should give you all the power you need for the phone to charge and activate the OTG mode.
Here's what you need.
USB hub with mini USB port for connecting to host device($5-$20)
Y USB cable($4)
USB Type A Female-USB Micro Male adapter($1-2)
Build subtotal-$10-$26, before tax or shipping. Depending on what you already own, this could still be cheaper than an HD Dock.
All hubs with a mini usb host port should work for this build. But if there are any that don't, please give me the make and model info so I can add them to the list below.
Hubs Confirmed Unusable
None so far
Thank you for looking this through. I hope it helps.
Update 11/7/12- Still works on the 246 OTA.

(Also, if this thread is in the wrong place, I'm sorry. I didn't think this was necessarily an accessory thing, but rather a way to utilize a built-in feature.)

Well, this rig works with wireless keyboards and mice. True, not the same as a tablet, but it'll get you further from the tv.
As for what you are suggesting, I thought I had heard some people were working on something similar. I'll PM you if I find it.
xda premium is insane! ... In a good way.
What Components
What is the amperage output of the power source your using? Also what is the model number of the usb hub your using? i tried a usb hub i had but it didnt work. Also did you have to bridge the pin 4 to ground on the micro plug in essence creating a otg cable?

Ok. One thing a a time.
Power.
In the action shot, I used my laptop. However, the charger that comes with the phone works as well. That's 5.1volts, 850mA
Model of hub.
I have tested 2 different hubs at this point. At the moment, the one from the photos is unavailable, so I can't get the model info from it now. However, the other I tested is a Manhattan 4-port USB hub, model 160612.
Connector.
I made no modifications to the connectors that I have used. They were, however, already being marketed as OTG adapters. I ordered the one from the pictures on dealextreme. I recently bought newer ones from ebay that are angled up the side of the phone. The new ones work as well.
I suggest that you make sure all of your connectors are secure. A proper connection will have the phone charging while the hub receives power. If it fails to connect to a device after 1 minute when you make your first connection, disconnect the phone and than reconnect.
If you still have trouble after, please post what you're using along with a pic of your setup. With any luck, we'll get it all sorted out.
Working portable prototype
I have a working portable prototype using a 9v battery as the power source. I think the problem with the initial test is that i wasnt waiting long enough for the phone to detect the usb hub and the memory card. Now i have it working fully. I have tried 2 different usb hubs and both worked. 1 was the micro innovations usb204n it worked but was a bit bulky. The second was one i bought from a store local to my home called biglots its an E Source brand 4port usb 2.0 $7. Its nice and slim with an extra ac port on the side. The setup ill be creating is i will wire a 9v battery to a 7805 voltage regulator (with an inline power switch of course) soldered directly to the pins of the ac port. Then i will desolder the usb plug and solder in my homemade otg cable. So all you will have to do is plug it directly to the phone plug in the usb drive and then flip the power switch. i dont wanna post pictures of the ugly prototype so ill have pictures of the final product this weekend. I will say that i found out a usb hub is not needed to use a mouse but the otg cable is. Thank you silversonic for your help

Battery powered usb hub
Ok so i finished the battery powered usb hub that connects to any micro usb phone but it was to bulky using the 9v battery. So i came up with another design using an old cell phone battery. So it is rechargeable as soon as i add the on off switch it will be finished.
---------- Post added at 09:41 PM ---------- Previous post was at 08:44 PM ----------
The usb hub was just too bulky using the 9v battery

Rechargeable battery powered usb hub with otg cable
Here is the finished hardware. I took pictures before i seal it all up so yall could see what all i did. The usb hub has a otg cable that plugs into your phone. It has a 950mah cell phone battery and the circuitry from an emergency charger that converts 2 aa batteries (3v) to 5v. Also on the circuitry was an led flashlight so i decided to keep it in there just in case . The only problem was that the off switch that was on the circuit wouldn't shut off the power to the hub for some reason so i put a secondary switch on the power wire to the hub. I had a problem with the charger charging the battery because it charges the battery based on voltage and the capacitors were screwing that up so i put a diode on the power going into the up-scaling circuit board but not as to break the connection with the charger to battery wires.
That is certainly the most mobile solution to USB host so far. Kudos!
problem
I was having a problem soon after I put everything together. Anytime I plugged the phone in the circuit would shut down because to much amperage was being pulled from the battery and as a safety thing lithium batteries will shut down so they wont over heat I finally realized all I had to do was put an 8ohm resistor on the power wire going from the usb hub to the phone. 8ohm only because that was what I had. I tried a 1/2ohm resistor and it worked but the less amperage being pulled from the battery the longer it lasts and the circuit doesn't get as hot.
hey man, thanks a lot for your research! i hopped on this thread and about 30 seconds later i had my wireless (unifying usb receiver) logitech keyboard and mouse working
had a male->male usb cable, usb hub, and micro usb male -> full female lying around. plugged everything in and presto!
the touchscreen monitor doesn't work though for webtop
More than likely because touch screen drivers aren't as generic as mice or keyboards. But it was a good thing to try out. Mind sharing the make and model info? It will be helpful to others to know what to expect.
Mine works, cheapo Micro Center hub
I actually spoke with the OP this weekend, and before I read his reply, I was up and running. Sadly, I bought a Manhattan hub based on his findings, which was a bit pricey given the current price of normal USB hubs. I paid $15 on ebay for one, and when I got it, it didn't work. I then bought a usb Y cable from ebay as well, and that was the culprit, that cable was necessary for any hub, regardless if it uses an AC power adapter or not.
On a good note, that means that there's a good chance cheaper (and easier to find) USB hubs may work. The one I'm currently using is Gear Head brand, was $9 at Micro Center. That hub without using the included power cable, and just using the Y usb cable bought separately and the OTG adapter on ebay got me up and running.
Hmmm...now that I look, it seems the hub I got for $9 went up to $15 anyway, but here's what I used incase you have a MC closeby and don't feel like waiting for shipping. Search for SKU 280750 on Microcenter's site. I'm new here so it won't let me post URL's.
Bad news is you'll be paying a total of around $20 for this project, the good news is that may be the maximum you'd be paying, and that's if you buy a $15 usb hub. Honestly, I'd say just look around local stores for one cheaper that has a mini USB port to connect it to the phone + external power usb port (i.e. a laptop next to the phone), and if it doesn't work, return it as long as you can box it up without it looking demolished. Best of luck to everyone, but I hope my verification shows there may be more hope since the Manhattan model is fairly hard to find at a cheap price.

Sorry for the delayed reply.
I buy generic cables from meritline.com, so there is no brand on them :good:
I think I'm the first person on Thingiverse to create an accessory for the droid bionic, what do you guys think of it:
That was iteration #1, to get the dimensions correct. From here, I can go anywhere. Do folks have any dock dreams they'd like to see come to fruition?
For a while now I've wanted to be able to use my waterproof camera to take pictures, and use my phone to upload them to the web without needing to fire up a computer to do a transfer from the SD card to the phone. This thread inspired me to finally take the leap to work up an OTG adapter. I went on Amazon to buy the Y-cable and the little adapters, but found something better.
This (board won't let me post a link because I'm new) is a USB hub that connects a phone to one of the four downstream ports with a built-in micro USB connector cable. I ordered one up, suspecting that I could mod it to be an OTG adapter. I was right.
To do the mod, the first step is to pry the endcap off the micro USB connector and slide the cover back. This exposes the soldered wire connections. One side of the connector has three wires.
The other side has one wire and an empty solder pad.
Solder a jumper wire from the empty pad to the black wire on the other side.
Then slide the connector cover back over the connector, and press the endcap back into place. If necessary, you can secure the end cap with a drop of super glue.
Next, open the case of the hub. Mine pulled right open with only finger pressure. Use a small screwdriver to remove the circuit board. It is not held by anything other than a light press fit.
This is the back side of the circuit board.
This is the chip that runs the USB hub.
I googled the chip number and downloaded the data sheet, just to be sure there were no gotchas. There weren't any. The only modification is swapping the regular and the micro USB cables. It goes without saying that this requires a very fine soldering iron and a steady hand. Desolder both cables and reattach the micro USB cable on the Host end of the circuit board.
This lets your phone control the hub. As was mentioned earlier in the thread, the Droid Bionic won't power the hub, so you need to hook up the other USB cable to the device side of the circuit board to provide power. Only hook up the power wires. Just cut the data wires short.
Then reinstall the circuit board into the case.
And press the cover back on.
It would be easy to wire a battery to the hub either by connecting to the USB port cable, through the 5VDC power input jack, or by removing the jack and hard wiring directly to the circuit board.
To use the adapter, I plug my SD card reader into the hub, plug the power USB connector into my wall adapter (or car adapter), and plug the micro USB cable into the phone (in that order). The phone immediately loads the card as an attached storage device.
Enjoy,
Todd F.

Where to buy Micro USB to Micro USB Cable (UK)

My problem is simple, i'm tethering my Wifi Nexus 10 to my Galaxy S3 and the S3 just doesn't have the staying power of the tablet and the AP is battery intensive.
I have considered:
Extended battery (unofficial) - don't want the bulk.
Extended battery (official) - not cost effective.
The other option would be usb otg and charger cable but I'd like a single cable if possible.
To make it clear - I'm looking for a double ended micro usb (B) cable.
If anyone knows of a reason this wouldn't work please do say
You could use this adapter with your original cable to see if it dies the job.

I have the same setup (nexus10 and s3) let us know if it does work.
You could try monoprice.com. I get all of my cords and such from them.
eBuyer tend to be pretty good for this stuff.
Just FYI, I tried this using an OTG adapter and a standard USB-A to USB-B micro cable. Depending on which side I plug the OTG adapter into, the S3 charges the Nexus (when the adapter is plugged into the S3) or vice versa (when the adapter is plugged into the N10).
EDIT: It would be interesting to try though what would happen if one was to connect the four pins (VCC, D+, D-, GND) directly to one another, with the ID pin being left unconnected (since that is what a Micro-B to Micro-B cable would most likely do). My guess is that nothing will happen, since neither of the devices assumes a master/slave state and so it doesn't know that it should supply power to the other device. I guess I need to order some Micro-B plugs at Digi-Key and whip up a cable...

[MOD] PDMI Charger Port to MicroUSB Port Hardware MOD Completed!!

Since it almost impossible to find a PDMI Port, I retrofited a MicroUSB port.
I even contracted FOXXCON, got a reply contract DELL for replacement part.
I have Charging and Data + / - (Detected by PC) working fine.
Only Issue is that the device shows it's not charging when Power ON and connected to PC (Hardware Charging LED is lit).
-Maybe this is Normal??
It does show charging when power on and connected to Charging Adapter.
I will post pictures when I get home today.

PDMI connector to mini usb connector
Hello man. My name is Mario. I come from Italy. I'm a psychologist,but on the spare time I like to play with linux & mobile & tablet & technology in general. I was searching for a OTG adapter that was able to recharge my nexus 10 and at the same time that accepts an external sd card and someone has suggests this to me :
eKit 4 in 1 Data Sync Connection Kit For Samsung Galaxy Tab 2 10.1 & Note 10.1
you can read the full story here :
http://android.stackexchange.com/qu...ard-and-recharge-the-battery-at-the-same-time
the problem is that I haven't read very well what he says and I haven't understood that it is not good for the nexus 10. For this reason I have tried to search a way to convert the PDMI connector to a mini usb connector and I have found this thread. I would like to ask you if I can make the same thing that you have done and if you can tell me which electric modification I have to make to the board of this connector to convert it as a mini usb connector. Thanks.
