USB connector problem - serious help!!

Hi all ...
I'm new here, I'm an electronics Engineer, but I think I got to a dead end with the USB / Charger connector.
it broke 1 year ago and I bought a new connector soldered it with an SMD soldering iron.
everything worked fine, charges fine no problems.
when I wanted to synch it, it refused to connect. I changed the versions to make sure it connects but the PC keeps on saying that the USB device cannot be recognized.
I went through all the pins that I soldered and made sure nothing disconnected or shorted.
all fine but I noticed one thing ... that one of the smd components is missing.
its so small " less than 1mm "
I just need some tips to troubleshoot the problem.
which pins are for serial communication via USB?
any diagram available to help solving this problem?
I have sent it to the agency and they were un able to help ... they just replaced the connector again that it was already working.
device is : i-mate PDA2K original ROM version WM2003se.
Thanks in advance

visit blueangel section of wiki.xda-developers.com. there should be a pin out of its connector.
if you don't care about syncing and only want backup, a simpler solution will be to use SpbBackup or Sprite Backup program that runs on your phone.
good luck

Actually I need the synch facility to upgrade the ROM. I have been using cab files since ages with this pda so synch. is not for downloading appz.
I have seen the pin config. for the car handsfree connector. I think it will help.
still I need some help with the internal schematics the USB +/- Data pins internal schematic.
Thanks

hmmmmmm........ive bin googling the data connection may be this may help.... http://geektechnique.org/images/usb-connector.jpg

Thanks for your effeorts, but I was looking for the PDA pins, more percisly is the main board schematic at the pins cuz I think there is a real mess there and I need to trace every pin to fix this problem

XDA EXEC mini usb connector help

Hi,
need to know what type of mini USB is on the circuit ? how many pins?
thanks

All mini USB connectors should be created equal, usb (including usb mini) its what is called an idustry standard, thay have 5 pins total, same shape and size always, I wouldn't even suspect that some connector maker could took off any of the pins out, what surely should be, is that the connector must be a PCB mounting type, it would be a better idea to open the PDA, take off the connector and bring it with you when you buy the new one.
One easy solution -that I think someone in the forum has already mentioned- would be to use another device's mini usb conector (such as a broken bluetooth headset or a memory multicard reader).

hopefully tommorow i'll be able 2 post photo

Damaged Usb Fitting

Hi there, I hope someone can help me.
The USB connection on my phone as been damaged.
My questions are:
1. Is it easily replaceable?
2. Can i swap it out with any USB Fitting, or does it have to be a Prophet usb fitting?
Kind Regards

Part is easily repaired, but only to be done by experienced technicians, because the size of the connector is very small ... the USB port and can be replaced with the like which are also widely used by digital cameras and MP3/MP4 Player.

[Q] [Xperia S] Soldering on the USB-Port

I'm wondering, if I'd want to solder something to the USB port (internally of course) and the attached device is not connected, would I still be able to use the port as before(charging, etc.)? Provided I would not use > (IIRC) 5V together, could they be use simultaneously?
Why I'm asking:
I found an old OCZ Trifecta (SD to USB-Adapter with MicroSD slot) laying around. Stripping the thing down reveals a really thin logicboard, which fits almost perfectly under the normal back cover.
So I thought, if I could wire the USB connector of this adapter to the internal one, I could have additional storage. I don't know if this specific adapter is SDHC compatible, but since there are newer ones around, I could get one of those.
Thus I'm asking for advice:
a) technically possible?
b) if yes, how hard is it for a semi-newb?
c) potential trouble I should be aware of? Not meaning loss of guarantee, more about possible hardware destruction.

In theory if you rigged it up to work like usb otg and charging then you might be able to get it to work. I think it takes a resistor to trigger it.

No you wouldn't need a resistor, you just need to short pin 4 and 5 together on the micro usb side. That's what makes it an OTG cable. Check out the picture I attached. That should be the wiring you need to make it work. Refer to the link below.

In theory it should work. The hardest part is attaching wires to the pins of the micro usb connector. It so [email protected]#$ing tiny... not the easiest thing to do. Unless the pins of the connector goes though the other side of the board, then you can solder onto the solder points itself. That should be a lot easier. Any potential problems? You could screw up your micro usb connector... then you might not even be able to charge it if you lose that...
Good luck. I would be interested to know if you succeed.
BTW Micro SDXC 64GB in FAT32 works in my Acro S running CM10 with Nova Kernel. You can gain a lot of storage!

is it possible to charge mobile while it is in OTG mode?

Thanks for your inputs.
According to this video it doesn't seem to be too easy, guess I'll need to wait a few days for a buddy, I'm not yet skilled enough for such delicate work.
If somebody has more skill and faith in his/her talents, you should be able to get an adapter for <5€ practically everywhere.
