Need help: USB Device Not Recognized error message

Greets gang,
Several days ago I started getting the subject message appearing in my WinXP system tray. It was on my Gateway laptop and it would appear over and over again, citing 'Unknown Device' when you'd click the annoying ballon. My Jam wasn't even connected at the time.
I basically blew everything away and restored my laptop to factory original settings. Problem persisted. I thought it might be hardware, but the message has now disappeared, only re-appearing when I plug in my Jam. My USB Bluetooth dongle plugs in fine, no errors.
Someone else had bent pins on their USB port or plug--I see none. Anyone else have issues with this, or can anyone offer some help?

Presumably you have installed (re-installed) Active Sync on the PC? As you may already know, as standard the JAM and many other PPCs are not recognised by the computer unless Active Sync is installed [properly].
www.softick.com provide an excellent utility to have your PPC recognise as a removable drive without using Active Sync.

Yes, ActiveSync has been installed & re-installed. New development? I plugged in an 80Gb external hard-drive to that laptop and Winblows is telling me its connected to a non-hi-speed USB port, which it is not. Could be something there.
I'm going to re-flash the Jam to factory ROM, then I will dig into the USB issue.

I had this problem and I tracked it down to the fact that I had picked up the wrong cable!
Same connector but for my camera

The wrong cable thing may very well have been it, but I was also having probs with an external hard drive I was using. I ended up rebuilding my laptop twice and now things seem to be fine. What a drag.

I have the same problem.
It seems, this problem appears mostly on laptops, not on PCs?
I tried to uninstall\install, repair with all ActiveSync data removal or leaving it - No result.
Also, tried to replace the cable (which is ok, im sure with the one from the camera) - No result.
Temporary way out: do Off\On with qtek9000 on cable connect.
Another way out: Turn On the "Enable all incoming beams" flag in Start -> Settings -> Connections -> Beam (this path may vary depend on your Universal brand name). As I seldom need to connect via IR to other devices, I have switched this option off to consume power.
DOES ANY BODY KNOW, HOW TO FIX THIS BUG?? Any Ideas?
Qtek9000 with laptop Toshiba Satellite Pro \ Win XP SP2

it seems dat a noob like me at last can give a help
i have the same problem last time, and as i trace it down, the problem lies on the cable.
as u know that we all use mini usb (usb cable type b) for our o2 mini, but not all type b cable support pc connection, some will only give charging access
i have 2 mini usb cables, one comes from my external hdd, and the other is i buy it myself. the difference is that the 1 i bought actually have a shorter connector (maybe the problem due to this)
so try to buy another cable, as i don't know any other way (reinsatalling pc os, hard-reset device or reinstalling active sync won't solve the problem)
NB. both cables are working when i plug it to my external hdd, so maybe the cable is not faulty. one of the advantage that i got is that i can charge my mini without disabling the active sync usb connection
sorry for my bad english

i can almost essentially confirm that it is NOT the usb cable.. I have been using a usb cable i had around the house for syncing my phone, and it has worked perfectly ever since I first received the phone (over half a year ago), but all of a sudden, i plugged in my device, and received the "usb device not recognized" error message... does anyone know the cause of this?

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

[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

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. Here's their website for more info http://www.emergeretail.com/Default.aspx

Cant connect hd2 to computer!!

this is my problem,
when i connect my hd2 it charges but the computer doesn't recognize it. on the phone settings it is set to active sync. i also have 2 computers; xp and vista, both do the same thing.
i could careless about active sync, i just want to plug my phone into my pc and transfer files in and out. ive also tried the disk drive option but still no go?
if i enter bootloader and plug it in it recognizes the usb setting but when the phone is normal, it doesn't??
it did this with the stock rom and its also doing this with nrg titanium rom.
any help would be appreciated

Same thing here.
It charges through USB but it doesnt connect.
If i choose the storage option it works fine.
I want to sync my outlook and i cant...
What the heck...?

i know this may seem a bit "it helpdesk-ish" but try re-booting your PC

Come on... give something drastic!
Already done that, rebooted the pc and the hd2...
still nothing

believe it or not i have done that mannyy times and did alot of device manager things to try and let both computers recognize the hd2 but still nothing haha..
ive had previous hd2's and they've all connected fine untill this one, maybe its this specific one thats giving me trouble. but regardless, it charges via usb then it should be able to recognize it

Check the active sync settings to ensure that usb connections are enabled. You can tell be looking at the system tray icon - there's a read circle with a white X in it if USB is disabled.
Saying that though, if it doesn't even recognise it when the device is in USB mode, I'd try a different cable. It's perfectly reasonable that the cable could power the device but not fully facilitate a USB connection.

That is very weird. Sorry mate - never heard of it doing that for anyone before.

Make sure you have the mobility center/active sync program installed on your computer. Without it it won't work.
On Vista or Seven, with the HD2 plugged in, you can find the program/drivers by launching and refreshing manually Windows Update. On XP you have to do that manually.
Good luck.

This happens to me often. In my case I have found it to be a weird driver issue. Go to device manager and look for the yellow triangle. Right click and update driver software. This worked for me I hope it helps.

bit late but just flashed maxsence and i love the look, but have allready had to restart by phone 10 times in 10 minutes. I'll wait for the next release. back to GTX for now.
Good work NRG. keep it up.

this is one of the many WM6.5 errors!
need Android soon!

Ok here we go.
The phone did not connect through activesync to my pc. When i selected to connect as mass storage it connected.
I checked for driver issues in device manager but nothing came up.
I checked the hd2's activesync. Bingo! the activesync was crashing when i was running it. I had to hard reset the phone.
Now it works fine.
My guess is that maybe a program that i installed recently was buggy and created this particular problem. Unfortunately i have about 50+ programs installed (including themes etc) and i m not sure which one it was.
I was installing all the programs again today one by one and after the install process was completed i connected the hd2 to usb to find which app was the problematic one.
After installing almost(some were found useless) all of the apps (here is the crazy part) the hd2 still was connecting through activesync....
HTC will drive me nuts...
Anyway the phone now connects correctly.
I cant understand which was the problem....

as odd as it may sound i think i figured it out.
i think its the usb cable that im using, i have to wiggle it around for it to connect to active sync but once it connects its not a stable connection as it cuts in and out.
but charging capabilities work though!
pos wire, i ordered a new wire and if that one fails also, i will have to get my hd2 replaced for faulty usb port
thanks for all the replies much appreciated

@k20a1
Try to hard reset the phone.
It worked for me.
If not again, then use your warranty!

i did whenever i custom rom'd it, it still does the same thing. yes it will connect via usb while in bootloader but will not during regular phone operations lol

"Disk drive" mode not working with XP laptop
HD2 is working fine with my desktop, but wit laptop I can only use ActiveSync to browse files.
When I connect the USB cable I get:
"Found new hardware wizard"
but it tells me that it Cannot Install This Harware - Disk Drive
"An error occurred during the installation of the devie The system cannot find the file specified"
And I only have "Finish" to click - if I click it the wizard lunces again immediately and goes on and on with no end.
HD"/Leo does not appare in Disk Manager (I know ablut the drive lettering issue)
I'm sure its my XP issue, but I havent found drivers to fix that, and I'm not about to reinstall XP on my lappy in near future.

I share the same here and I was despaired of trying to solve it with any logical, as well with illogical, measures. Such as: rebooting, changing usb cables, reinstalling activesync 4.5, etc.....etc...blla..blla...blla...
However, I solved the "Transfer files issue" by taking out the sd card from the HD2 and connect it with an external cards reader to my pc.
The card reader connected and works with the same usb cable that does not work with the HD2.
That way I load it with all files and in the same occasion I reload into my computer the daily spb backup files.
However, I have the feeling that the reason for that problem is a missing file/driver named: "Setup1.SPL" in the pc windows operating system.
In order to solve that it seems that only reinstalling windows on my pc will be the solution which defiantly do not like.

[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.

Thanks for the help guys!
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.
