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?

Problems connecting

I have a tmobile MDA Vartio2 and I have numerous problems with it and need to upgrade soon but this one I cant sort.
I can't connect via usb to sync with my laptop. If I set up a new connection it will sync but as soon as I reattach to sync it wont recognise the device so I can't keep everything up to date. it isn't the cables - power is fine and they work for other things.
I am runing it as I bought it 17 months ago - no upgrades or cooked roms or changes of any kind.
Can anyone help.
I want to upgrade to something else but I always sell my old ones so I want to sort the issue first obviously even if I sell it.

Try turning off the 'advanced network functionality':
Start -> Settings -> Connections tab -> USB to PC
That's what I had to do to get that hack called activestin...^WActiveSync to work reliably via USB.
Really, I've not noticed any difference between having it on and off as far as functionality goes, so really, I have no idea what the RNDIS mode stuff is even good for.

I have just tried your suggestion but now it isn't recognising the device at all. It is seeing it as far as power goes - its charging over USB but activesync isn't seeing it.

Check activesync itself:
File -> Connection Settings
Make sure "Allow USB connections" is checked.
If that still doesn't work, I'd try the uninstall, reboot, reinstall activesync dance and see if that helps any, provided that you are using activesync under XP.
I'd also be suspecting the sync cable. Recharging a device and getting a data connection are two different things. I have a blue angel that wouls charge via the USB sync cable, but would not sync, XP kept complaining about an unknown device. Turned out it was a broken wire in the cable.

Done all of these already I'm afraid - I have 4 or 5 cables and none of them work for this - and I know they are all absolutely fine.

OK, let's take stock of things. I'm assuming that you are using XP.
Hermes with the advanced network functionality turned off doesn't show up at all when you plug it into USB. So, we have a lower level driver issue going on.
Provided that you have not turned off all sounds in your current sound scheme, does the computer make any noises when you plug the phone in? If the data side of the connector on the phone is in order, the computer will make some kind of beep noise when you plug in a USB device.
Also, have you looked at device manager when the phone is plugged in? With advanced network functions turned on, a network adapter should appear. With out the network bits, it should show up as an HTC USB Sync device.
To eliminate something on the phone software-side (I know, you said that you have not touched anything, but try it anyway, this is windows, the environment that gave rise to the term bit-rot), put the phone into boot loader and plug it in to see if the computer sees it. It should appear as a HTC USB Sync.
If it still doesn't show up, I'd be popping over to another computer and checking to see if the phone will be recognized by that system.

For the past few weeks when I plug in I get references to acquiring network addresses (like a wifi network) but then it does nothing. Now I get nothing at all when I connect apart form power.
I have already tried re-installing active sync (just done it again in case I did something wring too)
I refuse to beleive its my cables at this point because I have 3 in front of me that all worked perfectly before everthing suddenly went wrong. Unless someone had cut all of them at the same time - this couldn't have happenned.
I am going to try and plug into the pc and see what happens (as apposed to the laptop which should have the connection.

I think this is good news (on the part of my laptop) because its the same story on the pc.

Double edged sword there...
So we have potentially eliminated the computers (good), this leaves the phone itself (non-good).
Hard reset?
Otherwise, I'd start to suspect the USB connection on the phone itself.

I would say that my chances of rescuing this phone rather than getting a new one are getting slimmer
I think it is probably the port itself and I can't do anything about that one
Anyone want to buy one with non usb syncing functionality ?

usb connect issue

Hi
I am having a problem with my Wizard. This weekend i was taken by surprise by a downpour and my phone somehow got wet. At first it didn't seem like a big deal, everything seemed to work just fine but on monday when i got back to the office and tryied to sync my phone i've noticed the problem.
The thing is that it can't get an ip, the connection (usb) reports limited or no connectivity and can't get an IP thus, can't sync. The phone runs ok, i can get it charged;
Can anyone help?

I dont think so that its because of it getting wet, it might be a problem with your ROM or PC but still wait for advice by someother Senior member too.

There are two main possibilities:
1) If your computer can't seem to connect to the device via USB (it won't show up in the Device Manager, and may trigger an malfunctioning device error), it's possible the water short-circuited your onboard USB controller. This might render a data connection via USB to the host computer impossible while still allowing the device to charge off the Slave voltage pins.
2) If you can connect to your wizard and the device (if, for example, it shows up in the Device Manager), that means that serial communications are working just fine, as, if your computer was able to interpret the USB Device ID, your onboard USB controller is most likely not damaged. In this case, I'd probably try screwing with your ActiveSync settings, and focus on undoing anything you've changed recently, like USB drivers on the host computer or ROM on the device.

My Touch just doesn't show up on PC

Hi, I'm so new to WinMo and this forum
My sis just gave me her Touch and asked me to back up her contacts. Now she's using a Nokia E65.
First I used a regular Mini Usb cable to connect the phone to PC. Nothing happens. My PC (the OS is Windows 7) didn't even show that some device had just been connected. I tried on my laptop (running XP) and it's just the same. Uhm, not really. The laptop shows that "USB device not regconized".
But the phone showed that it was charging. The cable is fine, it is the one that I use to connect my N95 to PC. I didn't try the cable included in the phone package, however I'm not sure my sis does keep it.
Then I tried to use bluetooth for Sync. Since my laptop's bluetooth just didnt work, I went out and got an external USB Bluetooth device (or is it called Bluetooth USB Dongle?). My PC regconized the Bluetooth device immediately, and I was able to sync my N95 with PC using PC Suite.
But then it didnt quite regconized my Touch. Sometimes it did, sometimes didnt. Sometimes my Touch did really get connected with the PC (after the Passkey part). Then I refreshed to see services to use from the computer, but nothing shows up. In fact sometimes it showed "ActiveSync", but after I refresded it just disappeared. So I just couldnt sync my Touch with the PC.
What should I do next? Do I have to send the contacts one by one to her new phone (it's about hundreds of contacts). Could it be the USB connector(s) on my phone that were broken? And after a hard reset should everything be fine? (I think I will do that after backing up the contacts).
Thanks for reading my bad English

I used my girlfriend's cable (from her Nokia N95, same to yours) and it worked perfectly with my HTC Touch, so maybe you have an hardware issue...
Are you sure that ActiveSync accepts incoming connections? Have a look at the app in the device

Lol, it's just a regular cable from a package which I was given. Not even the original cable of N95. But, well, it works perfectly with N95.
Where can I change the incoming settings?
But since nothing really happens everytime I plug the Touch to the PC, I think it's a hardware issue too. It would be bad (costly?) if I have to get someone fix that thing.

Go to Start > ActiveSync, then tap the Menu button and select Connections... Be sure that the option is cheched and USB is selected...
I have an italian ROM so i'm not sure that the words will be exatcly the same...

Yes, everything was checked. So that may be a hardware issue.
But I can still charge with the cable, while I cant do any data thing. Is that something weird?

That's strange, but i don't know how is the device made, so it may be possible...

Questions to ask.
- Are you using the latest ActiveSync + Drivers?
- Have you tired different USB ports?
- Different Cables?
Is your activesync settings point to usb?
Go to the config to check

Lol, I finally got my Touch show up on PC.
Last night I did it once with the Bluetooth connection. But that connection was so unstable that after that one time I couldnt do it again.
I tried a few more times, but it was still the same. Then I searched on the Internet, and someone showed the solution for the Touch not charging when plugged to PC: untick the box "Charge when connect to PC" (or something like that). I did the same, then plugged the phone to PC. Then the sound of some device connecting to PC suddenly appeared. I was so surprise, and when I open Windows Mobile Device Center and see my phone connected, I just couldnt believe in my eyes ) Just untick some stupid checkbox, and the problem that was giving me headache for a few days suddenly gone.
Today's morning when I tick that box (meaning the phone will get energy from USB connection to charge) and connect it to my PC, it still recognized my phone. Now I can check or uncheck that box, and the PC will recognize my phone no matter what.
Lol, it feels so strange using a WinMo phone. I've never used a WinMo before, just Symbians )

Well great to hear that, ping us back if you have further problems.
Actually Software issues is easy to fix, but when it comes to hardware problems, like the IC chip and all those, its a big headache.
All the best for your HTC Touch

HD2 won't connect to PC

Hi there,
I've had my HD2 for 2 weeks now and its been working perfectly. I decided to hard reset my phone and start again from scratch. However, now when I connect it to my PC it doesn't connect or recognise it at all, it charges though. I also tried it on my laptop, thinking it might be my PC but its just the same. This is really frustrating and any help would be greatly appreciated.

Goto "Start/Menu/All Settings/Connections/USB to PC" and ensure ActiveSync button is green.

If you are running Vista or Win7 you have to install Windows Mobile Device Center. http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/device-center-download.mspx
If not the normal Active Sync will not see the phone.

Hey guys. I know this a old thread. I notice ever since I used the program here to change the radio on my htc hd2 that my computer no longer detects my phone with snyc cable even if I have Windows Mobile Center 6.1 installed an such. The programs pop up though when I look on device manager there no unknown devices or anything. In fact I don't even hear a sound of any sort that a usb device was plug into my pc same thing on my laptop. I even put back original tmobile rom on my htc hd2 no resolve. When I fflash it with Leoimg.tbh or how ever you spell it I put it in my sd card. Any ideas on how to get the old phone to work on windows 10 again? or is something mess up in the coding on official rom or on how I flash it back to stock?. I wish I had a old pc with windows vista to see if it just windows 10 or what. Just seems so odd

no reaction from phone nor pc
Hi, guys i have similar problem, but it has nothing to do with Active Sync. The device won't notice that it is connected to the pc (it won't ask (this option is ticket) if it should act as card reader, modem or Active Sync) so as pc won't show new device. Strangely, while the device is connected into an outlet charger via cable including data wires and "don't charge if connected to a pc" option is ticket in hd2, it acts as it is connected to a pc and won't charge. When it is connected to a charger with unseparable cable (which i suppose hasn't have data wires) it starts carkit menu. For me it seems like something is shorted but i'd like to hear some other suggestions before i try to disassemble it and look inside.
