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?

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?

Please help me get activesync to stop disconnecting

Ok, ive got activesync working fine on one of my pcs but on the other it disconnects after about 3 mins. both have identical software antivirus/firewall-wise the only difference is one has a hardware modem/wireless router(the non-working one) and the other uses a wireless usb hub to connect to the internet.
Ive tried pulling the ethernet cable from the back of the non-working pc to no avail, disabling windows firewall etc but nothing stops it disconnecting after about 3-4 minutes.
Ive tried all the suggestions regarding tcp/ip, they were already correct as were the dhcp ones.
im completely baffled by this
the wmstorage program works for a bit longer but gives the error "the device is unavailable due to an i/o error" after about 5 minutes
anyone have a clue why this is happening?

Odd question to ask. Is your unit set to switch off after 3 mins? Just check if the device is on/off (you can have the backlight off, but you should able to see something on the screen) when the activesync disconnect.

on battery power its set to 2 mins but on external (usb?) its unticked. it works ok on the other pc though thats the thing so i assume its a pc settings issue :wink:

As you plugged into the PC directly (not through a USB Hub)? USB hubs have been known to cause problems.

im using a usb extension cable straight into the usb 2.0 card , the only other device is a printer and the keyboard which share a usb hub on another port.
The cable works fine with other devices ie digital camera/camcorder so its not a faulty cable.
Im using a hub on the pc that works (and its only usb1.1) and it shares with the wireless dongle
One thing i did used to get while transferring data was the avg email scanner popping up while my ipaq (which worked fine) was connected. i disabled the email scanner to see if it helped and rebooted but it was no different

ok-think ive fixed it-the (brand new) usb cable must have been faulty cos i connected the mda cable straight into the pc and it worked :roll:
thanks for all your help :wink:

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

USB not recognized

When I plug my phone into my usb port I keep getting an error message
That says
USB device not recognized
one of the usb devices attached to this computer has malfunctioned and windows does not recognize it. For assistance in solving this problem, click this message.
So when I do that it says unknown. I know I have the drivers installed because I can odin back to stock. I am thinking this is the reason why wired tether will not work.
Can anyone let me know what the problem may be?
Thanks.

This has happened to me from time to time. A reboot of the pc and phone has always fixed it.

I just realized I have never used this cable with the phone. I got it at walmart and it is made by fuse. So it could be the cable.

Also try a different usb port. Mine got error error messages on some ports but not the other on the same computer.

I bought several usb cables for cheap online. 1 totally stopped working, and another one disconnects the phone is I move the cable.
I always suspect the cable!

I am having the same problem with my laptop atm...
My computer can't seem to see the epic when it's in d/l mode. I've installed the samsung drivers as well...but no go.
Hopefully someone has a suggestion to fix the problem. I'll be seaching the forums in the meantime.

had the same problem try a different usb port aslo dont use usb multi hubs.

I have the same problems as well.
A reboot fixes nothing.
None of my ports work.
I do not want to replace my epic but this simple issue is nerve wrecking.

I have a similar problem. Both my wife and I have the epic. I have no issues connecting my phone to either of our computers but when I connect my wife's epic neither of the computer's see the phone at all (not even as an unrecognized device). The phone asks if I want to mount the sd card and I say yes and nothing happens. I've tried usb debugging and I can't get Odin to work either for hers (fine for mine). Has anyone else had this issue?
Thanks

USB 3.0 Transfers fail

Hi,
I've been struggling with this problem ever since I've had the Note 3 ( since December). I've been unable to find a solution so am turning to this forum in the hope that someone can shed some light on this.
When I connect via my USB 3.0 port and select MTP (usb 3.0), then try to transfer a file from the note 3 to my pc, the progress bar comes up but sits there at 0% for a while then a message pops up "a device attached to the system is not functioning".
At this point going to other folders reveals no files although the current folder still shows them. This suggest that there is a disconnection of some kind.
Switching back to plain MTP this transfer will work but obviously at usb 2.0 speeds.
I am running Windows 7 and the usb port I have is via a card attached which is an Asus u3S6 (usb 3 / sata 6) card. The chipset on the card is a NEC chip and my other use for it is a bunch of external SATA drives in a USB 3 enclosure. Needless to say there are no problems with running these drives through the ports.
I have Kies 3 installed so any usb drivers needed for the note 3 should be fine. I'm stumped so anyone that can help me troubleshoot this I'd be grateful.

Have you tried enabling " USB Debugging " ?

Yes sorry I forgot to add that fact. It makes no difference.

Guess no one knows

i have somewhat similar problem, at some point of usb 3 file transfer the progress bar freezes and so is "my computer". interestingly the file transfer to note from the pc always works fine, but it always freezes at some point when copying files from note to pc, even during kies backup. usb 2.0 works flawlessly.
i've messed around with usb 3 drivers (asmedia) and even updated its firmware but the freezeups still remain.
gonna try usb 3 transfer on a different pc tomorrow.

This sounds like a different problem but I did get to the bottom of my problem which turned out to be the Anker 2 port hub I had connected to the usb 3.0 port. I didn't think to eliminate this but when I connected directly the problem goes away so the hub I had bought purely to extend the ports for convenience is faulty or incompatible.
Perhaps you have an extension or hub too in which case I'd make sure you connect directly.

USB3 seems a bit flaky in implementation. I had probs with my N3, a Corsair USB3 stick and a USB3 ext HDD. Problem turned out to be the ports on the PC. They would work with most devices but were intermittent or non-functional on others. Of course, among the USB3 devices it WOULD work with were the ones the vendor had. For some devices it behaved like the USB3 extra connectors in the plug or socket weren't long enough - push it in harder or push it sideways slightly and it would connect but drop as soon as you let go. (not good to do 0 USB carries power and this is a good way to get an arc across the plug and fry things)
The PC vendor gave me an add-on front port panel and all is fine now. Even though it plugs into the same port on the MB.
Note the USB3 HDD still pops up the 'check drive' error every time I connect but I haven't taken the time to nuke it and rebuild yet. But the Corsair now works and so does the phone.

Ah, the joys of the MTP protocol...
Same issue here. As well as it stops responding halfway through a transfer, crashes the connection when making a new folder, takes about 3 years to copy 1GB, randomly disconnects...
My TF700 started doing this after the 4.1.2 update removed UMS. My S3, same story. My Note 3, same story. 29 different computers, 4 different systems (XP, 7, 8, OSX). Different cables, different ports, with and without drivers, with and without USB debugging.
I bloody hate MTP. It's useless, limiting (because now it can't be used as a drive to attach to a mediaplayer via USB..) and about as stable as nitroglycerin during an earthquake.

I thought I'd give up on hubs and just get an extension as my USB3.0 is on the back of the computer and not that accessible.
I've seen a lot of complaints about hubs and simple extensions that have this poor connectivity which seems crazy to me since it's a bit more important to have a solid connection on USB 3 plugs, besides which it's not as though the usb connectors are rocket science.
I'll try the extension and hope I get a reasonable one.

well i did try the usb 3.0 file transfer on a different pc with a different usb controller and it worked fine, copied my 5gb music folder to the pc without any problems. so in my case i guess it's some incompatibility with the asmedia 104x controller (i did connect directly in both cases and the same cable was used).

it seems like it is indeed MTP issue here ! i rolled back to the old 2006 microsoft driver and i managed to do a full backup including music and everything else with kies. but after a while i tried again and it froze up again, i'll keep experimenting.

Sorry to resurrect this 3 month old thread but is there any way to fix this?
Whenever I want backup anything from my phone storage to PC, I have to do it in chunks of like, 50 files or less (huge PITA with TiBU). If I try to copy the whole folder, my computer locks up and I have to hard reset it. I've tried everything mentioned here short of buying a new USB3 controller.
