I bought some really cheap retractable cables of ebay. When I got them they didn't work at all. I opened and rewired the micro-usb connector - the cables were connected all wrong, but after a little soldering I think they're correct.
Now the cables are working fine with my Nokia N82, but when I connect them to my Desire and Desire HD my computer won't recognize it as USB devices, only charging.
I've looked at the pinout here http://www.kineteka.com/microusb-b.aspx - should pin 4 be connected to GND to use it with HTC?
Any tips?
I was curious of the pinout, thanks for the link.
As far as wether the pin should be grounded, well... if it's not working ATM ground it and see if it works? Since you're successfully charging the phone you know you connected the +5 correctly, grounding any other pins won't cause damage...
Cheers
P.S. Also sometimes good to check the obvious, did you enable the Mass-Storage option in Android?
I've had similar issues with USB 1.1 ports.
Are you connecting it to a USB 2 port??

I have just purchased a holder for my XDA2 which has a mini USB port on it and I want to connect my TomTom GPS receiver RJ11 connector it.
Does anybody have the same problem or a lead which i can use?
Thanks
if the rj11 connector have all the same connections and signal protocol as usb and maybe even a normal usb connector in the other end then you can buy a normal usb to miniUsb converter
The TomTom reciever has a RJ11 connector and i can not seem to find a converter from RJ11 to anything i.e. USB, Mini USB, etc.
Do you know of any places?
Pratik
well rj11 is a phone connector right ?
and you are sure it's even usb compatible signals running in it ?
i mean if it's analog modem data stuff then converting that signal to something which usb can work with would be a pile of work and end up being more expensive then getting a new gps
True.
RJ11 is a phone connector, but the information from the gps reciever is just being passed to the PDA holder which has a Mini USB connector in it, so I don't think any data conversion is necessary.
The RJ11 has 4 wires in it and the Mini USB has 5, maybe i need to open it up and desolder the mini USB and put in a RJ11 female connector, this then brings me down to pin-out etc.
Do you have any information regarding hte pin-outs?
Pratik
you can get a cable with a mini usb in one end and normal usb in the other if you can get a cable with a mini usb in one end and a female usb in the other then you can connect the usb to xda connector cable that way
of cause that way is way too long but it should make it rather possible to connect the xda to the holder then that is unless
the pda holder and miniUSB connector's signaling require the pda to be a usb host which the xda1 and 2 is not able to be
Maybe we are getting the wires crossed.
The following is a link to the holder
http://www.pdamods.com/proddetail.asp?prod=SPKXDA2&cat=75
The XDA2 sits in the holder just fine and charges at the same time, as it has a connector on the holder, the problem is the GPS connector.
I don't understand your responce to the XDA being a host?

RJ-11 to Mini USB Adaptor
I have a pocket, USB Modem at home, and it is RJ-11 on one end, and Mini USB on the other.
Have you tried looking into something like this for a solution?
I want to get a second cable to charge my touch pro while I am at work, can I got and buy any 5-pin mini USB cable or do I have to order a HTC cable?
Standard cable will be fine
I've just looked at the USB cable Expansys sell (http://www.expansys.com/p.aspx?i=166227) but looking at the picture the plug is a differant shape to the socket on my Touch pro. I can't find anywhere that sells a cable that looks like the socket (rectangular with bottom right corner chamfered, I assume everyone is the same). Can anyone point me in the right direction?
You already have answer from ardsar
For charging standard mini-USB cable is ok.
Yes, and what I said was that a standard mini usb has a differant plug. How can I use it if it has a differant plug?
yes it does, but so did the HTC3300, but the charger and data cable use the 'standard' mini usb connector.
I have one (car charger and 'standard' usb cable) and they both fit fine, work fine and charge fine. so no need to worry.
Basically, a normal mini-usb plug will fit in HTCs proprietary socket

WARNING! CONNECTING ANY CABLE TO YOUR PHONE THAT DID NOT COME WITH YOUR PHONE IN THE BOX COULD DAMAGE YOUR PHONE, YOUR COMPUTER, THE ELECTRICAL WIRING IN YOUR HOUSE, AND IT COULD KILL YOU!
you have been warned
Soooo I recently stumbled across this thread http://forum.xda-developers.com/showthread.php?t=744636&page=3
that states that if you short pins 4 & 5 on a micro USB connector and plug it into an HTC Desire, the phone will automatically go into car dock mode. as luck would have it, I happen to know that this is the same method that is used to trigger USB OTG on devices that support it. The wheels in my brain began to turn... $7 and a few days later I came up with this:
MICRO USB HOST ADAPTER + A BIZARRE A TO A USB CABLE = A CHARGING/DATA CABLE THAT TRIGGERS CAR DOCK MODE!
I have tested this on my G2 using Virtuous G-Lite 2.0.1 and it works perfectly, but YMMV.
I got the USB host adapter here
http://www.amazon.com/Micro-B-Adapt...3?s=electronics&ie=UTF8&qid=1328093895&sr=1-3
and the A to A USB cable here
http://www.amazon.com/StarTech-com-...3?s=electronics&ie=UTF8&qid=1328094123&sr=1-3
Just in case you haven't already figured it out you just connect the female end of the OTG adapter to either one of the male ends on the A to A cable, then use the cable as you would any other charging/data cable in your car. the only difference is that now your device will automatically switch into car dock mode when you plug it in! you could also connect this cable to a dock that has a female micro USB connector on the back (like the G2 OEM desktop dock here http://forum.xda-developers.com/showthread.php?t=1473718) and create your own car dock!
an extra word of warning, DO NOT USE THE A TO A CABLE ON ITS OWN FOR ANYTHING! this is a non-standard conforming cable that would damage any two USB devices that you attempted to connect with it. I have no idea what it's intended use is on it's own, but don't think that it is the same thing as a USB data transfer cable (transfer cables have a chip inside the cable that makes the two connected USB host devices see each other as USB slave devices. this A to A cable is just a copper wire)
Nice, I didn't know people wanted this. I got a premade cable. Off ebay that triggered car mode no mods needed and it was a buck. Lol

Any idea about standard dock mode? I know the official tmobile dock auto opens a desk clock.

My guess would be that the cable was not intended to trigger car dock mode, it was just poorly made. a really bad soldering job on the pins would short pins 4 & 5 and do the same thing. Other people have reported this same behavior when they buy low end cables or get water in their micro usb ports.
I tried this and it seams to work but all it does its launch tunein radio, any idea how to change it to other apps such as torque? Thanks
The short thing does work. I my self stumbled on to it while repearing a aftermarked charger .. I opened up the mini usb side and it had a resistor on jumping pin 5( - ) to pin 4 . With the resistor on it charches with the resistor bypassed and just jumped to pin 4 it goes in to car dock mode. Also my friend got a samsung infuse and came with a hdmi dongle usb, so out of curiosity hooked it up to my g2 and it whent to car dock mode

Hi all,
I have a Philips AS111 docking station/bluetooth speaker/charger. Worked perfectly for my SGS2, however, since I bought a new phone (Sony Xperia Z1 Compact) I'm experiencing some problems.
I bought an micro usb to magnetic connector adapter to be able to connect my phone to the dock without having to open the flaps all the time. I took it apart and it basicly splits the first and fifth pin of the micro USB connector to the pins in the magnetic connector. Unfortunately I may not link to external images...
Unfortunately, my phone does not charge when using the adapter in combination with the Philips dock. It does when using the original Sony USB charger and the adapter, so the adapter is fine.
I measured the voltage on the two pins, and it's 0V. I even tried to fool the dock by putting a 1.5kOhm resistor over several lines. Only when I put a 1.5kOhm resistor between 5V and the connector housing, the dock responded by turning on Bluetooth. Voltage went crazy, flipping between 0 and 3V, but phone still doesn't charge.
I think the sollution is to fool the dock by putting a certain resistor between certain lines or by shorting certain lines. Does anyone have a clue how to fool the dock to think there is a device connected, so it opens the +5V line?
Thank you very much!
Nobody into usb connection protocols? :crying:
Finally got it working. Eventually I needed to connect two wires together inside the device. One of them being 'CLAS1' and the other was Ground. Both could be found on the connector going to the micro usb plug of the device. Unfortunately I can not post a link to the photo I made of it.

Hello!
I've just bought an AS111. Charges perfectly my SGS4 but it doesn't do a thing when I try connecting my SGN3 (the one with the micro-usb 3 connector) to the Philips dock. I know that the micro-usb 3 is backwards compatible but I do believe that the AS111's dock outputs too little power - or something like that, I am no expert.
I was wondering that maybe your experience could be of help to me. What do you think? If so, could you please guide me through the stuff you did to the dock? Thank you!
Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .
I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working
So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed
Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?
