Hi @Technotrousers,
Welcome to the HP Forums!
It is a terrific place to find answers.
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I grasp that for your USB is not recognizing devices until you have rebooted your system. You have tried uninstalling and reinstalling the drivers but no change.
Would you try these steps
Go to Computer
Right click and choose manage
Double Click on Device Manager
Click on the USB to expand
Right click on one of the root hubs and choose properties
Click on the power management tab
Uncheck allow the computer to turn off this device to save power.
Repeat the above process for the remaining USB root hubs.
Please let me know the outcome.

"USB device not recognized." "The connection between your device and the desktop could not be established. Please check your setup and try again." Tungsten E2, Outlook 2007

Hi,
I am running XP SP 2, on a Dell Vostro 1000, Palm OS Garnet v5.4.7 on a Tungsten E2. I have worked though issues relating to synchronization, Outlook 2007, Docs to Go, etc., in the past. Thank you board members!
Once I worked thru all the initial problems, my Tungsten E2 was sync' ing beautifully to my laptop until a few days ago. There have been no changes (I know of) to the configuration, but now I receive "The connection between your device and the desktop could not be established. Please check your setup and try again." On the laptop I sometimes get "USB device not recognized." I am unclear why I get the PC message sometimes and not others.
I have tried the following: (not necc exactly in this order)
Double checked Hot Sync Mgr settings: Local USB (ver. 6.0.1)
Reset the Palm (multiple times)
Rebooted the laptop (multiple times before and after the Palm resets)
Went to Support Libraries including http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE/,/?St=57,E=0000000001060189973,K=9550,Sxi=3,Case=Obj(3695...)
and http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=PalmSupportKB,ts=Palm_External2001,Case=obj(1409)
Followed the steps in "Start Here" found at http://forums.palm.com/palm/board/message?board.id=windows_hotsync&thread.id=26057
Moved Backup directory as per a post on this forum
Looked for a deleted a file called "Graffiti_ShortCuts_____________" per a post on this forum
Followed the steps in HotSync troubleshooter guide you can run through located on
http://kb.palm.com
Went into Device Manager - found it shows no yellow ! 's
Followed Device Mgr Troubleshooter - went all the way thru with no solution
Tried all four USB ports - the PC's bell-like tone does not sound when I disconnect or reconnect the Plam's cradle like it does when I conn/disconnect other USB devices -I think that is a clue. ...?
Cleaned the Palm's contacts (and cradle's contacts with a old, dry toothbrush)
Read all the posts under "USB device not recognized."
OK, I'm at a loss, can anyone help me? Many thanks in advance!

Hello!
Using a cradle with the Tungsten E2? Tried bypassing the cradle and just use the hotsync cable? Tried a different computer yet? Somehow, the PC is having problems getting a signal from the device. I assume you have the laptop charger plugged into the laptop during this? Not going through a docking station or port-replicator.
One crazy thing you can try is unplug the charger from your laptop, remove the battery from the laptop and leave it out for like 10mins and put it back in and reboot the laptop. This should not cause side effects but still contact your OEM to make sure that nothing else is needed after leaving the battery out for extended period of time. Keep me posted.

USB device not recognized, and more!

This morning when I tried to sync m y Z22, I got "USB DEVICE NOT RECOGNIZED". Connected the cable to every one of my USB ports, tried to sync each time but got the same message.
I shut down the PC, unplugged it, waited a few minutes, reconnected it, rebooted, and tried to sync again. Still got "USB DEVICE NOT RECOGNIZED".
Checked Palm Support, was advised to upgrade to the current version of the software (I was using V4-something). Downloaded and installed the upgrade. I got an error at the end of the installation that (what I assume was my old software) had been moved to Palm OS Incompatible Apps.
I tried to sync again, same problem. Opened the (new) software & half my data is gone.
So, I have a few problems:
1 - How do I fix this &^#$!!! USB error? and,
2 - How do I roll-back the software to my previous version to access all my data? In Add/Remove Programs, with Updates checked, the new software is the only one there. (Because I couldn't sync, at least the data on my Z22 is still intact.)
Someone PLEASE help, my whole LIFE is in this thing!!!
Thanks in advance,

USB Device Not Recognized issues

I have a Qosmio X505-Q860 and I've been getting the 'USB Device Not Recognized' error constantly for several months. I've never plugged anything into any of my USBs and the error is now causing a nice Blue Screen (which happened about 4 times yesterday within 1 hour). I've tried uninstalling the problem USB hub but it keeps telling me that it failed to uninstall (I'm on my administrator account when doing this). How in the world do I get rid of this so my computer stops crashing and driving me crazy!?
Edit: I should also mention that everything is up to date (I check often and checked just now).
"A stopped clock is still right twice a day."

I suggest trying another USB cable. If you are positive that your cable is not the issue then try resetting the iPod and booting into disk mode (Hold menu+select down until Apple logo appears. Then hold menu+play/pause down and the iPod will go into disk mode, see if the computer recognizes it then. If that works then their is either a software issue on the computer or a firmware issue. Worth trying to restore but backup all your iPod's files first!

"USB Device Not Recognized" Bubble/ Ipod won't connect to Windows

Whenever i connect my ipod to my computer the ipod goes to "do not disconnect" and a bubble pops up on my computer saying "USB DEvice Not Recognized" i have switched it to all of my usb ports and unplugged all usbs except for my mouse at the same time. this happens 95% of the time. my ipod does charge while connected and it has only connected to itunes once in the past 2 weeks. im not sure if it is itunes because it started around the time i updated to itunes 7. since it is a windows bubble though i think it is a windows or ipod problem and not itunes. i have a dell that isnt great but works fine.
thanks for any help.
... Go TTU!

Make that two idiots. My roommate got a Sansa and I decided to try out the cable. Nothing happened. Now suddenly my nano isn't recognized by my computer. I'm glad I read your post, now I can stop looking high and low for a solution. Until this happened it worked good as new.

"USB device not recognized" when ipod plugged in???

(ipod mini 4gb)
When I plug my ipod into my laptop I get the message: "USB device not recognized." It says the device has malfunctioned!!! If I click on this error message it says my ipod is an unknown device and no drivers are installed for it???
It was working fine until a few days ago. If i reset it I can charge it up but that's all, it still does not appear in itunes or on my computer.
I've tried eveything on the help website but nothing works! Can anyone help?!
patriot 3050 Windows XP

ok my question is do you have a mac or windows based laptop
here is why and what happened to my ipod mini
my ipod mini was connected to my macintosh charging while i was using my imac and it came up with a system update 10.4.3 i installed it and finished installing it and afterwards my apple wouldn't recongnize my ipod mini or even display it one the screen i found out by myself that when the apple update got to the end of the update it installed new hard drive drivers but also installed the drivers on the ipod mini which locked out the mini's internal hard drive and my mini then stop responding it would play music and charge but wouldn't connect to the computer
so what i did to fix it was this
i went into utilites in mac os x tiger or any version of os x has this and selected disk utility you will notice that the ipod will appesr in disk utility but not on the desktop this is due to a recent system update driver that isn't compatible with the internal drive on the ipod mini so in disk utility just select format the drive in a mac os partition standard works the best it will then format the ipod and the ipod will apear in the desktop again but not as a ipod let me explain when you format the ipod using the disk utility it formats and even erases the firmware of of the hard drive on the mini so when you are done formating the ipod run the ipod updater to reinstall the ipod's operating system and presto your ipod will now work again
warning: i don't know how to fix this on a ipod in windows so if this is a windows based laptop you need to find someone witha macintosh to do this with sorry

USB Device Not Recognized (&IPOD WILL NOT TURN ON)

I have had an iPod Shuffle G2 for 6 months now with no problems until today.
It went flat when I was at my friends place so when I got back to my mums I plugged it into my laptop and it told me "USB Device Not Recognized One of the USB devices attached to this computer has malfunctioned and windows does not recognize it" I thought there was just a prob with that port in my laptop, so I put it in the other one. So I though Ill wait until I get to my nan and pops and put it in there computer which is where I sync it. Same problem in both ports. Except on this computer the orange light is on but doesnt flash.
Now my iPod doesn't turn on at all..
Which is fantastic..
Help yeah?
My mum is gonna kill me.

thank you for you help so far. I am very frustrated with this thing. I have been trying to correct this problem for hours.
I will try to disable virus protection. but I will have to enable virus protection again. what should i do?

"USB Device Not Recognized" Message when connecting iPod Nano

I get the following windows pop up when connecting my son's iPod Nano
*"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.*
I have successfully connected this device to this computer before so I don't know what has changed.

This did not work for me. I have a laptop that was running Windows XP, and it had no problems recognizing the iPod. I was having problems with XP, and rather then reinstall XP, I did a clean install of Vista. I did a settings transfer, so the new install of iTunes came already configured--I mention this since I don't know if it was a factor.
When I plugged in the iPod, I got the USB Device Not Recognized. The usbstor.inf file did not fix the problem. However, the solution at http://www.winvistabeta.com/groups/275128/ipod-usb-device-not-recognized/message .aspx did fix the problem. Do this:
Reset the iPod:
1. Unplug the iPod.
2. Turn the hold switch to HOLD and then back to off.
3. Hold the Center and Menu buttons for 6 seconds until you get the Apple logo when you release them.
4. Plug in the iPod. It should now be recognized.
This worked fine for me the first time. Thanks! Jack

2G Nano-USB Device Not Recognized message

2G Nano has been sitting for months. Decided to use it as a backup. When connected to computer (tried on 4 different computers running iTunes) I get a "USB Device Not Recognized" message. It shows up in "Device Manager" as an "Unknown USB Device" not an "iPod". Have performed the required 5 Rs and it still will not work. Any help would be greatly appreciated!

"USB Device not Recognized" when shuffle is plugged into computer

Everytime I plug my shuffle into my Dell laptop it comes up with the message "USB device not recognized". The shuffle doesn't show up in my computer or itunes. I've done some of things that it says to try, but I'd really like to get this fixed and get my shuffle working. Typically when I plug it in, it blinks once, yellow/orange, and then no more, and the notice comes up on the computer screen. If this makes a difference, the shuffle worked fine until last summer when my hard drive crashed. Upon installing a new hard drive, the shuffle began to not work/sync with my computer as it had been before. Any suggestions on how to get my shuffle working again? Much appreciated!

Well start with these articles and see if that gets you anywhere...

Computer says usb/device not recognized when plugged in??

When I plug in my sons ipod nano 7th generation, just recently says usb/device not recognized and doesn't light up when plugged into the wall either??? Any suggestions??

This came from another thread, but worked for me. Problem is with newest iTunes 4.62. Unistall iTunes, as well as its helper programs (Apple Application Support, Apple Mobile Divice Support, and Apple Software Update). Reboot, and reinstall iTunes. It will reinstall all the other ones and you should be able to connect your nano. Good luck.

USB device not recognized in Windows 7?

I have the strangest problem I've yet to encounter with my computer.
As you may have guessed from the title, I am constantly getting the message displayed. Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again (I'll get to that)
First off it started when I noticed my mouse pointer was acting very weird, it was just a vertical line of dots. A forum said an easy fix to the problem was to update my GPU drivers, which I needed to do anyway. So after an update to the GPU drivers
I log into my computer (which is password protected, this is slightly important to remember) and I try to go to youtube. I click down at the start menu to type in chrome and nothing appeared. I was able to move the mouse around and click on things
but I was unable to type anything.
Luckily for me I have a laptop as well so I checked for any solutions on my laptop and they said that it was a problem with the model of my keyboard specifically This was odd to me considering most of the problems happened OTB for the keyboard and not
a month after use, plus I was able to plug it into my laptop and it worked just fine. When I plugged it back into my desktop it gave me the same problem: I couldn't type anything, I also noticed the little pop-up informing me that the USB device was
not recognized. "Well, great, time to get my backup keyboard," I thought to myself. Except, that was not the case either. I plugged my backup keyboard into every single USB port on my Computer Tower, even going so far as to unplug
the mouse. Absolutely nothing was working. I constantly restarted my computer and each time got the same problem; I'm able to type in my password to log in and then a few minutes after that the USB device stops working. Sometimes after plugging
one of the keyboards back into a USB port I would get a message saying it was installing drivers; and then would fail in installing any.
After a bit I navigate through the menus with just my mouse and do a system restore to before the GPU drivers were installed. After that, I started windows in SafeMode and then turned my computer off. Finally, I unplugged my computer completely
of all plugs (including my power plug), waited a few minutes, then plugged everything back in again. Amazingly, this fixed the problem, but then it got worse.
After about an hour of gaming, my computer BSOD's, most likely because I decided to alt+tab out of Tomb Raider during a loading screen to stop a video I had on. I restart my computer again, and then the problem returns, only this time absolutely
no USB devices work except my one keyboard. The backup keyboard, and both my regular mouse and backup mouse stop working a few minutes after logging in. I try to fix the problem like before, but to no avail. Any USB device I plug in either
gives me the "USB device not recognized" or attempts to install the drivers and then fails.
If there is ANY way to fix this problem, it would be greatly appreciated.

Try cleaning the connector on the bottom of the phone. Use a magnifying glass to see what is stuck inside, a dry toothbrush and/or wood or plastic toothpicks (nothing metal). If that doesn't resolve the problem your phone is broken.

USB Device Not Recognized when Iphone connected to PC

Hello,
Every time I connect my Iphone 4S to my PC I get the error "USB Device Not Recognized". I did not have this problem before. I tried uninstalling Itunes and all its components and reninstalling it, restaring my computer, restarting Iphone and I even reset all the setting on my Iphone. I connected my wife's Iphone 4 using the same cable and PC and connected and started syncing with Itunes right away. If anyone has any pointers on how to fix this problem, any help will be much appreciated.

try reseting the phone
RESET DEVICE
Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).
