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.
Ok Guys and Gals,
I had a topic going on for a while about windows not detecting my Tablet.
we went round and round about drivers, Novacom, and even formatted my system.
But here what it was My micro usb cable.
My dog had eaten my Hp one. so I bought a generic one through EBAY
I my son took my cable for whatever reason so I grabbed the one that cae with my phone and it fixed everything
So heres my question
what is the right Micro usb cable to buy that will give optimum power abnd data transfer
A micro usb 2.0?
anybody that can help would be great
Any decent microUSB cable will work, its just 4 wires inside linking your Touchpad to your computer. I have used a Motorola, Blackberry, etc branded cables with no issues. Its not uncommon for cheap generic cables to have issues if they shipped with a defect.
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 noticed that the USB cable which came with my phone is a regular MicroUSB 2.0 cable. Looking at the phone USB connector, I see there are a couple of more pins on the both left and right side. Also on the specs there is USB3.0 support. Does someone know where to find an USB 3.0 cable for this phone?
Thank you
i have a galaxy S4 and have just ordered a G4 (standard micro usb). can i use my old car charger and pc data cable, are they the same as the G4 or do i have to buy new ones?
TIA
EDIT: gsmarena specs say micro USB 2.0 for both, so i'm guessing they're the same
With the exception of the new Type-C Nexus devices and a few odd samsung tablets, most android devices follow the same standards (to my knowledge). I think only the S5 had the USB 3.0 plug -- in which case the cable wouldn't work -- so you should be fine.
You can plug a micro usb 2.0 cable into a micro usb 3.0 device, but you can't plug a micro usb 3.0 cable into a micro usb 2.0 device.
But I want usb type-c to replace everything.

That should be a thing of the past now.
USB 3.0 never caught on and will be replaced with USB type C.
That is a good thing as the USB 3.0 end was a hideously huge waste of time designing.

Yes, the micro USB 3.0 connector is just crap. It breaks easily, and isn't particularly small anyway.
I had the S4 and I use the same charger and cable I used to charge it. That charger/cable is old now, at first it charged at 1900mAh but now it only reaches 900mAh. It is ok for a charge during the night. I had to buy a new USB cable that is charging a little bit faster.
I have a quickcharge 2.0 charger and cable that I use in extreme cases where I need ultra quick charges.
