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.
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...

I am interested if anyone knows the specifics of the micro usb connector used in the LG G2. I am only asking since I mixed up a Motorola Droid usb - micro usb cable last night with the OEM LG cable and thought my 24A update screwed the usb connectivity completely. It was just a cable mixup but it bugs me that the majority of my existing usb cables don't work with the G2. I would understand if the G2 had been shipped with usb 3.0 but it is a 2.0 spec but obviously a slightly different connector spec than older micro usb phones like my older Droids. I like the better connection - more tight and snug feeling with the G2 and OEM cable but I'm not sure what kind of cable to order if I was going to buy more for emergency or travel purposes. Is the new connector usb 3.0 compatible but simply not wired to usb 3.0 transceiever h/w ?

I just picked up a $3.00 USB OTG cable with a fullsized female usb to plug in USB sticks to transfer movies for the guys are work.
OTG is fully supported on the G2, (even shows the plug n pop Graphics of a usb stick inserting.)
Sometimes however it can get a lil finnicky in regards to format however.
I always format my usb sticks on the phone in settings then its good to go.
OK, so the format of the cable is not usb 2.0 micro usb but actually OTG (on the go). I was not aware that OTG had a physical connector change in it's specification, I guess I thought it was simply an enhancement of capabilities of the current micro usb connection. It's wierd how some micro usb cables seem to interoperate OK with OTG and some other don't.
Sorry for the misleading nature of this thread, I simply had a usb cable that went belly up and may have been working intermittently before. I just tested with a plain vanilla .99c usb-micro-usb cable and it work absolutely fine. I imagine the micro usb connectors on these cables can get hosed pretty easily and the G2's female connector seems to be pretty sensitive (some female connectors can be that way
Hi
I need some help around this.
I have a tab 3 (t315) i bought a OTG & MHL Adapter Micro USB Connection Kit HDMI and want to use it in the car for usb host and audio out.
Now I have a problem that this doesnt charge the tablet. Also dont know yet if i can output audio thrue hdmi with a adapter and at the same time use usb host.
Anyone can tell me how to make it charge and if i can use it as i think ?
If not how can i make a diy micro usb cable for usb host, audio output and charge at same time ?
Or if anything like this is awailable to buy somewhere
thanks
Hello,
I was wondering what the pinout is for the 7 pogo pins on the side of the RM3(s). I want to 3D-print a holder for the phone, with some extra functionality, just like the Magic Adapter. I can't find a pinout or even what protocol is used to communicate between the phone and the Adapter. Anyone know anything about the pins?

I posted the info a long time ago. You have audio and mic. L,R and Mic, power and gnd, then USB d+ and -. Careful powering stuff off the power and gnd it's not made to power devices. Inside the dock is a 4 port USB 2.0 hub controller not all the ports are hooked up that's how I added a micro SD card reader to my dock.

Thank you for your reply. I will test if I can get a USB output from the pins!

You can. It's got data + and -
How it works is that goes to a USB hub controller that goes to a USB Ethernet.
The micro SD card adapter I put on one of the unused ports.
