With the last kernels, our tab is able to recognise usb pen/hd in addiction to a 5 volt power sourge.
My idea (but it si possible that it is a your "old" idea :silly: is to use one of these 3 different solutions:
1) an otg 5in1 adapter conntect with the USB female port to a +5volt charger (no pc in order to don't have problem with data); in this case is it possible to use SD and micro SD ports?
2) modify this other otg 5in1 adapter creating an Y cable in order to have +5volt power; in this case USB/SD/microSD ports ok?
3) no modify with this adapter because it already has a +5volts entry....
Any suggestions or feedback?
Thank you for your attention and sossy for my poor english.

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.

...same for me. may I have a clear and "safe" answer for dummie?
- USB A male to micro USB A male cable
OR
- USB A male to micro USB B male cable
Thanks a lot.
only USB-B-male fit into the device, boy!
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.
Can we use otg adapter with nexus s, to directly connect pen drive to nexus and then use it as external mass storage?
no, must be additional power supply

You need a Y cable using either the charger or a battery pack to provide power.
when looking at the storage control panel, it lists internal, sdcard-ext, and then "/mnt/usbdisk_1.1.1" and says "insert an [sic] USB disk for mounting".
so if i were to come up with some sort of adapter, could i plug a thumb drive into my phone's micro usb port to move files between the phone and the thumb drive? i can think of plenty of times that would be useful!
Tried. OTG cable works with Samsung galaxy S2 devices (Skyrocket using either SKY ICS or rooted OTA) but haven't got it to work on our Droids...(Bionic ICS leak, RAZR ICS OTA, Droid 4 ICS OTA...all rooted).
But if someone can prove me wrong I'd be happy to "eat my words" ...

OTG works, BUT only in a very cumbersome way, since external power is needed.
A powered USB hub does not suffice, since it only powers the slave devices, not the host (= phone). The phone must be in charge-mode, which requires a Y-cable.
You need:
- an OTG adapter
- a USB hub with mini-USB in
- a USB Y cable with 2 normal USB plugs and one mini-USB out
Then
1. Connect the OTG adapter to your phone's micro-USB input
2. Connect the 'middle' USB plug of the USB Y cable into the OTG adapter
3. Connect the 'outer' USB plug of the USB Y cable to a charger (can be a portable battery as well)
4. Connect the mini-USB plug of the USB Y cable to the hub output
5. Connect any device you want to use to the USB hub
It looks like this (found this picture for Razr):

Edit: I verified it for Droid 4 last week, but didn't take my own picture yet. Works with ICS .215 leak, no 3rd party apps (like 'StickMount') seem to be needed.
Edit2: According to some other posts in this forums (search for 'OTG') it will only work for FAT32 formatted drives. Didn't check this in detail but my drive was already FAT32. Also I found it did not work for my cheap wireless keyboard's USB dongle, but connecting a wired keyboard worked fine.
...reminded again why I love this community...
...no possible links to a purchase of this "y" cable?
Be strong and very Koragus, my ninja...
Glad I could help!
They come with some portable harddisks, so that's where I got mine. Not sure about the linking policy on XDA, please remove if not allowed. Here's an example:

Hello,
For those who don't use the search function enough for already discussed in length subject :
I was just confronted to having a skype conversation on my nexus and trying to plug my OTG cable to check some stuff. And oh surprise, the USB is really near the jack ! And guess what, the shape of my plug device make it impossible with the OTG cable. But fortunatly I'm equipped with 2 OTG device and the second one makes the deal.
So, for any of you who is about to buy an OTG cable, maybe this experience might help you doing the good choice. Because you need to have your headphones in the train while you are watching a movie on your USB key.
Pic :
This has been discussed at length in the many OTG threads.
Where did you get that USB OTG ?
I want it!
I've found them on Dealextreme (dx), 3 weeks shipping but worth the deal
Mini adapter : Micro USB On-The-Go Host OTG Adapter (Pair)
Adapter with cable : USB Female to Male Charging/Data OTG Cable for Samsung i9100 Galaxy S2 (5CM)
+
USB key : Genuine SanDisk Ultra Mini USB Flash Drive (16GB)
Works like charm on my SII and nexus 10.
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...
