unknown usb identifier

I've got an 'old' XDA II (PH10B), and I don't want to miss it. My problem is the USB connection. Due to unknown circumstances, the USB chip has lost the identifier, so that I can't synchronize with USB connection due to unknown device. Serial, bluetooth and irda still works. Is there any possibility to restore the USB-identifier back into the PDA. I've restored the rom and radio via serial, but it doesn't fix the usb-problem

USB sync
You may change your USB sync cable. Your problem may be solved

That was my first trial!
The problem is exactly described above. and it has nothing to do with async ,pc, cable or something else.

Thank you. I never would have thought of that, since the phone is charging.
But changing the cable actually worked

hmmm...
i kind of have the same problem . my device freezes when i connect it via USB to computer .
Actualy it does not freeze when Advanced USB functionality option in Settings is on ... but ActiveSync does not start ...and nothing happens .
The funny part is that it worked ...some time ago and i tried to connect it to another computer and it works .
the only thig i haven`t try is to reinstal windows on my computer

Try plugging it into another USB spot on your computer. The cable and phone obviously work, which suggests that maybe the USB hub on the computer doesn't have enough power to charge and function. This usually happens when using front panel USBs. Try the rear USB ports.

usb freeze
i'm having the same problem as quantico said
"""my device freezes when i connect it via USB to computer .

well....mine did worked untill one month ago,and then suddenly had this problem..
the problem is not the computer that i'm sure,i have tested on a friend's computer and problem persists..and i have reinstalled my os from 32 bit xp to 64 bit xp and active sync works fine,cause i have another device a hp 6915 and it's ok...
the cable seems to be the main problem,but now i'm not sure...i have tested the pins with a ohm meter in the both ends of the cable and it doesn't seem to be somethin wrong..apparently..i will reinvestigate
then i thought the problem was my rom(3 monts ago when i bought the phone did upgrade from wm 2003 to wm6.1 using Shekhar's rom which had a few bugs, and so decided now to go with the latest,Ather's dark edition 6.1 which so far works like a charm(best recomended for hima)...but again problemo not solved..
i still think that the cable or the back connector might have a problem,but here in romania is hard to find a qtek 2020 data cable and also a cheap one so...untill anyone has some brilliant ideas ..i'm just charging my phone from usb

i have retested the cable with the ohm meter at both ends and cable is fine ,no broken pins,no shortcircuits...
i have pluged the usb cable into the pda moterboard connector and tested the usb at one end of the connection and on the mainboard of the pda at other end(phone dissasambled no power) all tests indicated that the fizical connection between the usb and motherboard pda is fine,and no other shortcircuits or broken connection..
that leads to another conclusion...there is an internal pda circuit or chip mailfunction of the usb function due to hardware or software problem that i cannot explain..typically for those models.....
those problems are not new,a lot of mp3 players after a while crash like that with usb device mailfunction or card readers or usb hubs.. but why?
so...we're back at the start of this thread

It seems that I have the same problem with my qtek. Some strange things happened. Unpredictable disconnections with usb. As above, I updated several month ago with the Ather WM6.1 rom. But the strange usb disconnections still exist. I bought a new usb cable. No change.
Since today the qtek doesn't charge either anymore trough any pc or in my usb charger in the car.
I guess something went wrong inside the pda...

usb drivers
I had problems with win7 and usb drivers. Came across these and it allowed me to flash roms. As i was having connectivity problems I thought these may help

xp
the cable is not the problem ...because i tried on another computer ..and it worked ...
the problem is the XP ...and the drivers

its it win 7 32bit or 64 bit?
im using win 7 x64 still have the problems

Need help...

i have a t-mobile mda wizard and every time i plug it in to my pc it says device not recognized but it charges and everything... i just bout a new cradle and everything but no dice on it connecting and im running windows xp... help will be appreciated

Right click the activesync button in your toolbar and open connection setting. Click connect device. It will try to connect. If it won't, the best thing is to go thru the help thing. Do you have a custom rom?

active sync do not work
Hi there, i heard some days ago (a friend who ask me for help, unloking wizard to change ROM) and his WIZARD was not able to get recognized by PC it was a bad contact between USB conectors and cable, so he sent phone to repairs and then he was able to sync and then to migrate from WM5 to WM6.1
perhaps is a connectors trouble.....

What version of Activesync are you using? If it's 4.5, you should be good to go. I have seen problems with older versions.
Also, check Activesync on your phone. Make sure you don't already have two accounts created, because that's the limit on your phone.
If not, try different USB Cables and different USB ports (or test those things on a different device with microUSB connection) before assuming the connector on the phone is bad.

as far as i know the phone is completely factory no upgrades or anything i tried to do the connect thing thru active sync where it looks for my phone still no connection and i bought a new cradle and usb cords all together and it still doesn't work...

USB connection issue

Hi everyone,
Since I'm new with this phone (just bought it few days ago) I really need your assistance.
My problem is probably with the usb drivers (Mass storage device). I'm running on Vista Ultimate SP2. When I connect the phone, and go to the notifications, there are two (as supposed to be). HTC Sync and the one with the USB connection. Well the one with the USB connection appears and disappears all the time.
As a result I can't sync since there is a problem with the USB driver. When I disable the Mass storage device (this is the one responsible for that), I can sync. The problem is I can't use my phone as a storage card in order to copy files. In advance I'm saying that I tried to mount the sd card...nothing.
I've tried the phone on other pcs, XP and vista... it workds everywhere fine. The notification with the USB connection is not disappearing.
Tried everything, rolling back the driver, updating etc. nothing!!
PLEASE HELP ME!!
Thanks in advance

Also remember than not all USB cables are the same.
I'm not using the original one as I lost it with the original box.
But while the Nokia DKE-2 works great for all functions, my camera and my USB HD mini-USB cable only support few features.
All of them can charge the Hero, though.

The one I'm using is the original one! Moreover, the phone connects properly with other pcs!

So the problem is Vista.
I personally used XP with only some minor problems due to the cable.
http://forum.xda-developers.com/showthread.php?t=557310

It should not be Vista... I've tried it on another pc with Vista.... no problem!!

Oops, ignore this.

Have you tried different USB port on the sick Vista PC?
Have you installed Andrid specific USB drivers? If so, uninstall and reinstall.
When you plug the cable do you get on the phone the notification for USB connection?

Adding a question to the topic:
I own a Galaxy right now and consider switching to the Hero, one thing that does not work with the Galaxy is the USB connection to my car for audio playback. The USB interface of my car can't handle multiple drives as offered by the Galaxy; e.g. with a HTC snap everything is fine.
So the question is: Does the Hero offer one drive only when connected in the USB mode?
Thanks for your help!

[Solved] HD2 Connection problem with Win7 & WMDC

Massive problem, HD2 gurus please help me here:
HTC HD2 & WMDC & Win7 x64 = Not working.
I've downloaded WMDC x64 bit from Microsoft's official site, installed the app, plugged my phone in the USB port..... and nothing happens. Win7 x64 does not pick up the phone via any of my USB port (I've tried like 4 different USB ports already).
Here is the weird part, Windows doesn't even pick up the HD2 as an USB device. I doubled checked via Task manager, and nothing has been detected. I have scanned for new hardware via the device manager countless of times.
Nothing shows up, not in device manager, nor control panel. Having WMDC installed doesn't help either, the app simply doesn't recognise HD2 via USB cable. Even with WMDC uninstalled, Windows just can't detect my HD2, but when I plug my Nokia N97 in the same USB port, Win7 picks it up as a mass storage device straight away.
Basically the phone will only charge the battery from the USB port, and nothing else. Win7 x64 doesn't even flinch when I plug the phone in, nothing pops up, WMDC says no device is found. I've tried just about everything, googled a bit and it seems like I'm not the only one that's suffering from this problem.
Here is a list of all the possible solutions that I've tried :
Ran WMDC as system administrator

Click to collapse
Took ownership of the WMDC application

registry key in question:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost\WindowsMobile
- Right click -> Permissions -> Advanced
- Took owner ship of the registry key
- Gave the Users group Full Control.
Then in device manager:
- Scan hardware changes

Uninstall WMDC & WMDC update via Windows control panel, and plug the HD2 in without WMDC installed.

Ran services.msc via run command, disabled Windows Mobile 2003, and re-enabled it. Fiddled around with both Windows Mobile serivces by disabling and re-enabling them

Please help me, this is a great phone and I can't wait to use it properly. But this has been an incredibly annoying experience.

Edit :
Problem solved. Turned out that T-Mobile's USB cable was broken, I had to use my Nokia N97's cable to connect my HD2 to my PC

Had the same issue last night when I first tried to sync my HD2. Same issues, ended up being I needed to update the Bios on my motherboard. Ironically it worked after I plugged it in and failed the driver install. Then went to Device Manager and ran update driver for the picked up devices. Works like a champ now. Hope this helps in some way.

Somehow I doubt that I will need to update my motherboard's BIOS, as my PC picks up the Nokia N97 perfectly fine. Having said that, I'm busy dling my mobo's latest BIOS right now.
Will let you know how it works out.
Edit : Nope, just as I thought. Didn't rectify the problem, thanks for your advise though.

Okay, the BIOS update scared me for a second there. I didn't revert back to the default setting after the BIOS update, which made all the USB ports malfunction on my PC. I couldn't use the keyboard nor the mouse, but I solved that problem by clearing the CMOS with a jumper.
Anyway, that's not the problem... The PC still wouldn't reconise the HD2. What I have noticed is as soon as I plug my HD2 in the USB port, HD2 automatically runs the activesync.exe
Having said that, the PC still can't identify the HD2 as an USB device. Absolutely zero response from Windows 7 x64. I've been trying to rectify this problem for over 6 hours already. I have googled dozens of pages, tried just about every single solution (bar the formatting option, which I will leave it as the absolutel final resort).
Please, can someone help me.

Gentlemen, have any of you tried a usb hub?

For the heck of it, have you tried it on a different PC? Have you tried a different cable? I am not sure what cable the N97 uses. I apologize I'm not trying to be an ass or anything, just wanted to find out if it's the handset's micro USB connection problem.

Yes, I have tried it on two different laptops, both have Win7 x86 installed.
I didn't install WMDC, instead I just plugged the HD2 in the USB port, hoping that Windows will automatically download WMDC and install everything on it's own. But alas, no luck with that either. Laptop could not detect the phone via USB cable, nor Bluetooth.
EDIT : OMG, I think I found the solution. Thanks, N1M1TZ. You actually did help me by suggesting the switch of USB cables. Since the Nokia N97 works flawlessly on my PC via USB, and the fact that both the HD2 and N97 uses the microUSB format, I was able to get the HD2 hooked up to the laptop. So it seems like T-Mobile's HD2 USB cable is the culprit. Well, it's in the bin now, I'm gonna use N97's USB cable for both of my phones in the future.

I'm glad you got it working. I had the same issue with my usb cable. Went out and purchased a replacement cable and found this ReTrak USB to micro USB cable. I have used their cables for most of my stuff from patch cord to adapters instead of my cables getting tangled or tied up together.

[SOLVED] HELP! Windows can't recognize the phone anymore

This is a new problem for me.
After successfully sorting out all the troubles of connecting SGS to KIES, and been using it happily for almost a month, now I'm facing another trouble which is quite big this time.
Windows Vista (32-bit) and Windows 7 (64-bit) are now can't recognize the phone when connected through the USB. Got a message says the USB Device/Hardware Is Not Recognized.
I'm using the SGS original cable. The cable was working perfectly and now suddenly it doesn't work in data mode but still able to recharge the phone battery.
Am I having a cable problem? Or worst, the USB connector (on the phone) problem? I tried to clean the USB connector on the phone but still can't connect the phone to my computers.
Does anybody here having the same problem as well?

I just gave up with my PC, same problem
In then end I set up a VMware XP machine to sync
Else I use my laptop
Sent from my GT-I9000M using XDA App

I sometimes have a problem with KIES detecting my phone. What I sometimes have to do is connect the phone with KIES loaded, go to device manager, show hidden devices then uninstall the phone (sometimes has error on device, sometimes not) then disconnect then reconnect phone.
Such a faff but using KIES to check for firmware update lol
This may not help ya but worth a thought, Im on Win7 64

I did not have any problem connecting the phone to KIES, I was able to upgrade the firmware from JF4 to JG4, and been a happy SGS owner for a month now.
But yesterday I suddenly can't connect the phone to any computers. My laptop (Win Vista 32-bit) said that a USB device connected is not recognized. I reinstall Kies in my laptop and same thing happen. Then I switch to my PC (Win7 64-bit), USB device not recognized also appear. Reinstall Kies, still no luck.
What I just realized is that there is NO USB Indicator in the SGS notification bar!
Does that mean that the USB connector on the phone going bad?
I still able to recharge the battery but the USB icon dont show up.
I am now seriously considering the quality of Samsung Galaxy S! Way too much problems for average owner, and even for savvy owners this is just over the top!
What should I do now?

Find another computer or install VMWear and see once and for all if its your phone at fault. Also worst case do a factory reset. If no go then you might have a hardware problem. You could always try Mass Storage mode and see if you can mount the phone as external drive. Its not really the phones fault but I would say its KIES, its just a piece of ****. I have never been able to connect to it using 3 computers and I would say I know what i'm doing since I work in i.t. Also did you replace your Launcher recently? As KIES needs TouchWhiz as default launcher to work

I just tried to connect SGS to another laptop (Win XP 32-bit SP3, no KIES though). Same thing, the USB device is not recognized baloon show up and no USB indicator in the SGS status bar.
I'm going to Samsung Service Center, after calling them, they suggest me to bring the phone to the nearest Samsung Center. They said that this is not the first time and also said that the problem might be the connector or the cable.

have you read this ? http://forum.xda-developers.com/showpost.php?p=8107646&postcount=50
Seems kies has a bug where it can't work with files with 16chrs or more.. Told ya KIES is a piece of ****
Yes, But did you try the Mass storage mode
Settings/About/USB

I always just use Mass Storage mode to xfer files. KIES is crap.

As I said previously, my SGS has no problem at all connecting to Kies. USB Mass storage is working perfectly as well.
The problem I'm having now is the hardware (the cable or the interface) I guess, since I still can recharge the phone using the charger or the USB cable.
ps. I'm using Kies from Australia, the 1.5.1.10083.

Have you looked at the pins on the phone? are they screwed? Can you somehow find or burrow another Mini-Usb cable to test ? I have heaps as some of my external hdd's use mini-usb but you might have to buy a new cable.

Try this.. I wrote this a while back.. It may help. I know you suspect it's hardware, but it might be worth trying anyway.

It's purely hardware problem. Yesterday I brought it to local Samsung Service Center, and because they said this is not the first timer, the technician quickly open the device and gosh... dust and some fungus were collected near the microUSB port! I admit I never close the USB port, just left it open after use, my bad!
After some cleaning and testing, the microUSB is working again.
Now I'm a happy SGS user again!

but that doesn't explain how it works on one Windows (Win7) but not on another Windows (WinXP)

The SGS wasn't recognized in ALL Windows versions, since it was a hardware problem.
Now SGS is recognized in ALL Windows versions.

download "usbdeview" and delete the usb drivers for the specific device.
