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?

Activesync Help!!! Can't figure this out

Alright so I've done quite a bit of searching but I can't figure this out and its really frustrating me. I have mfrazz's Windows Mobile 6 release 3 installed.
Rom version: 10.1.0.811 WWE
Rom Date: 8/11/06
Radio Version: 02.25.11
Protocol Version 4.1.13.12
My problem is that activesync will not recognize my MDA no matter what I do. I've hard reset my phone, installed and uninstalled activesync 4.5 a bunch of times. Done this on two different computers, but when I plug the mda in, nothing happens at all. I plug my roomate's MDA in (running a different rom) and it instantly recognizes the phone and begins to sync. I really want to try different roms out, but without an activesync connection I can't. Any ideas guys?
Thanks...
ps. Let me know if this should be in the WM6 forum, I wasn't sure.

Well,this problem has been discussed hundreds of time in the forum,just read through the forum,I'm sure you'll find answer to your problem easily,there was no need to start a new thread,or just hit the 'Search' tab at the top of this very page and enter 'Activesync Problems'.
Cheers!

Thanks for the feedback-
It seems like I've read every single thread related to this problem, but in almost all of those their phone is at least recognized by activesync. With mine, even after disabling all firewalls and doing all the suggestions in the other threads, I just can't get activesync to even recognize my phone

If you still can't sync at someone else's computer, you probably have a bad USB cable, or worse, a bad connector. Try a different cable (any USB to micro should work, they aren't specially wired or anything). If that's no help, try blowing out the connector jack on the phone (use a magnifying glass or ? to look for debris, too). If that's no help, you may be screwed. You can try these guys, but it'll be expensive (like, replace my phone expensive): http://www.drcellphone.com/index.php
Are you at least getting a charge light (solid amber) when you plug in?

Yea, it charges just fine and I get the solid amber light and everything. I use the same cable to sync my roomates' mda, so that isn't the issue. I'm really stumped. Im almost positive its something with the specific rom I have on my phone..
I've been forcing it into bootloader mode to try to flash any other rom onto it (I figure if i can just get ANY rom on it... official tmobile, or a cooked rom, etc. then the sync problem should go away) but I'm having troubles there too.

You're not trying to do this with a Vista computer, are you? There are known problems syncing with Vista-based PCs.
If you use Mozilla Thunderbird at all, you can try using FinchSync, just to see if the hardware is functioning properly. This is theoretical, though. I haven't tried this myself, so I can't offer much on FinchSync.

Nope, I first tried it with 3 different XP computers and then for the hell of it tried it with Vista. No go with either one. I've pretty much convinced myself that it is the rom I have on my phone (mfrazz's Windows Mobile 6 release 4) because I never used to have any problems whatsoever

OK, let's take stock of things. I'm assuming that you are using XP.
Check in activesync :
File -> Connection Settings
Make sure "Allow USB connections" is checked.
'Uncheck' the 'advanced network functionality' in the phone.
Start -> Settings -> Connections tab -> USB to PC
If that still doesn't work, I'd try the uninstall, reboot, reinstall activesync and see if that helps any.
I'd also be suspecting the usb cable/ mini usb port of the phone. Recharging a device and getting a data connection are two different things. I have a k-jam that would charge via the USB cable, but would not sync, XP kept complaining about an unknown device. Turned out it was a broken connector in the mini usb port of the phone.It maybe that usb cable connector is not making proper connection with the connector of mini usb port of the phone,try to 'wriggle' the usb cable plug a little and check if it tries to make a connection, while connecting to the phone,sometimes it helps.
Cheers!

I've made sure everything you suggested is correct. I didn't know that charging and data connection are two different things. I figure that if it charges, it should sync. The USB port on my MDA is really loose, and I can only get a charge when I plug in the charger and "push" the plug to the right an hold it there (usually by twisting the cord around the phone in a way that keeps the pressure on the USB socket). So now that you mention that, I'm just guessing that it charges but its so loose that I probably won't ever get it to sync again.
Hmm..
Is there any way at all to flash without an activesync connection? I tried flashing a bunch of roms by forcing the phone into bootloader and then running the RUU, but it always fails because it says I don't have an activesync connection...

Nopes !
You got to have connection with phone through usb cable.Get the mini usb port of the phone repaired or replaced,only then it can establish connection and flash a rom.
Cheers!

Alright, thanks a lot for all of your help! Looks like maybe I'll take the phone apart and see if I can actually see any disconnection on the main board, etc. Not sure if I'll try to make a repair attempt myself because I've read that the solder contact points are pretty small

Big Problems :((

I have the following problem with my HTC Touch HD. Since yesterday after i transfered 2 video files and a few pictures, when i connect it through USB, the computer doesn''t detect HTC anymore (nor syncing nor file transfer). Even the Bluetooth syncing does not work. I performed several soft and hard resets, and it seems it;s getting worse after every reset.
I bought the phone 2 weeks ago, after i sold my Apple iPhone 3G 8GB. As we speak, i kind of regret i did that...any advise for me ?
I forgot to mention: when i plug the uSB cable, the device goes recharging.

Have you tried booting your pc ?
Also try unchecking Settings/connections/Usb to Pc/ "enable faster data synchronization"
r
Andrew

What cable do you use? I had similar problems with non original (asus) usb cable.

greetings everybody..
1) i tried what you said several times, no result.
2) i get same results with the original and the other cables..
3) i noticed one thing . . . if i connect the device to a computer that i never conected before the device, it launches active sync....and Active Sync just wont interact with my device.

Did you try reinstalling ActiveSync on your PC?

yes i tried....same result. Do you think a change of ROM would solve that ?
Now, even a syncronisation using bluetooth is almost impossible, since i cant pair the computer and the device. Damn, it's like a virus or something.
stupid thought:

Impossible since i cannot connect using USB. Sorry !

I too had problems with my PC not recognizing the HD. Found out that it was a problem with my firewall and anti-virus. I adjusted anti-virus settings to allow active sync to pass through and have had no problems after that.
HTC also recommends going to Start --> Settings --> Connection tab --> USB to PC and deselect the checkbox for "Enable faster data sync"
For device recharging when plugged in to USB : go to Start --> Settings --> System tab --> Power. here below the battery charge indicator, there is a checkbox. Read the message and check/uncheck as desired.
Hope this helps !!

i thought one potential source for my problem would be the antivirus, but i disabled firewall (eset at work and symantec end point protection at home) and no result what so ever.
I cand figure a way to sync the device even with the bluetooth since i cannot pair the device and the computer.
I am starting to regret i bought HTC...

Try click the Activesync icon on HD Program, there is a "Option" on the menu, click and see if you could delete all the old connect. If yes, re-establish the connection again to see.....good luck

Option menu item is disabled (i performed several hard resets)...(
Another thing i noticed. I unchecked the box (when connected to USB charge), so now when i plug the usb cable, it wont charge. But, if the device is in stand by (black screen), and i plug the usb cable, it wakes the device up. So, in my mind, i think it is something wrong with the OS, it still "feels" the USB cable, but cannot (for an unknown reason) take the necesary action.
For 4 hrs i try to sync the device with the computer using bluetooth, and i cannot manage to do so.
Is there any way to reinstall ActiveSync on my HTC device ?

Tonight i will try to install at home Windows VIsta (at work and at home right now i have XP). I cannot use my phone - no phone number in agenda and it's driving me mad. The phone rings and there are quite a few persons i dont want to talk with.. HEEEEEELP

nobody there to help me ?

If you did a hard reset, and you can connect in drive mode, but can not sync, then I am 99.9% sure that there is nothing wrong with your phone, but that your computer is messed up.
Uninstall all your antiviruses, firewalls, and other bloatware, and see if it works then.

Just a possible solution, but did you try plugging in your phone into other USB slots on your PC? Are you perhaps trying to sync it through an USB extension cord, or maybe USB hub? I had problems with my PC recognizing the THD if I tried syncing that way. Best results were plugging it directly into the back side of the casing.
The reason I'm asking this is that if you have too many USB devices plugged in, it's possible that the USB voltage drops too low and devices won't connect to the computer.

I tried on 5 different computers, all available USB ports.
On a new computer, sometimes on the device screen it shows up Active Sync but that is all, no sync occurs. If i try again on that computer, i get the same result as i get using the computer at home or work.
The device cannot conect as a Disk Drive
Is there a way to reinstall Active Sync on HTC ? My guess is that this software is all gone with the wind (even i performed a hard reset). The big question is what the hell happened ? Could be a ROM fault ? I mention i never tried to change ROM, the only software i installed was S2U2 and Core Player.

If by monday it wont work, then i'll send it into service (i have warranty). But i hate service

all out of ideas...

Any ideas ?

Which items are checked when you go to Settings/connections/Usb to Pc/ on youre phone?
Have you tried to use another memory card (because youre problems started with copying)?

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

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!

"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.
