USB Device Not Recognized (Malfunction)
Posted 21 May 2010 - 08:29 PM
the steps which i followed are as :
1. in "human interface devices" under device manager. i disabled it. my usb mouse has already plugged in and its showing yellow color symbol in "human interface devices".
2. unplugged usb mouse.
3. plugged in usb mouse.
4. enable it.
its worked for me but don't know how long it makes me happy. i hope it won't come again otherwise i'll screwed up.
hope this easy troubleshooting will also help u too.

i have had this problem for the last few months....
here is the story so far....
iv had a lexmark x5495 for a few years and have a intel powered desktop pc...
i was re-installing the software for the printer after cleaning out the pc and and putting in xp again..
iv installed the printer and xp on a few computers in the past without any problems, im not as good with
computers as most of you. but i do get allong with them verry well. in the past i have swapped power supplys
heat syncs, dvd drives and have even swapped the whole inside's form 1 caseing to a new caseing without
any problems. i try to diagnose and solve problems myself with the help and advice from others on the internet.
but this is the 1 problem thatr has me stumped...
while i was installing the printer software it went fine untill i got to the point where you have to connect the printer usb lead.. my mistake might have been that the printer had the power lead installed but i have installed that way before.. after i pluged in the usb lead i found that it did not show as useual that it had found the device so i could not continue on... also the usb mouse had no light showing from underneath. nor did the usb keybord work
infact all the usb ports were now dead. although this is not strictly true as the external usb hub was showing power.
so it seems that although power is going to the devices, they no longer recognice being pluged in...
so i too now get the bubble telling me of the usb malfunction
i have tried before the method of turning the pc power off.. but im now trying it again without the backup battery on the bord.. (not sure what difference this will make??
i have also tried the method of uninstalling the usb ports then restarting the pc.. without sucsess
also i have re-installed xp and even tried a copy of windows 7
this makes me think its either a hardware problem or a bios problem
i am wondering if when i pluged the printer lead i have caused a power surge in the ports
the intel bord i have is D915GAG/D915PSY and it has a 3ghz pentium prossesor
if anybody has any new ideas or can help with an idiots guide to trying some of the more complicated methods
like changeing the bios id be verry gratefull...
i have a second pc and will soon be able to replace the 1 im having problems with, so i am up for trying some of more risky fixes as long as i understand the prossess involved. the main reason i want to try this is for future
referance and to learn more about computers.. also i hate giveing up on solving problems
sorry this post is so big but i like to try to pass on as much info as i can

I bought my HP Touchsmart TX-whatever the hell a year ago, and it worked amazingly well,touchscreen and all, until halfway through the summer. Then it started getting this USB Device Not Recognized error this is about.
The one thing that's odd about mine is only the touchscreen is affected -- I can't use it, and that's why I bought the darn computer in the first place. All other peripherals and USB devices function fine at all times. I've tried several fixes like listed here, and regardless of what I try, at some indeterminable and random time I will always get USB Device Not Recognized and the touchscreen will stop working.
Soemtimes it will say it just once and fix itself sometime later. Sometimes it will literally spam DA-DUN DU-DAN telling me over and over and over again until I restart it, to which the N-Trig application then says "device cannot be opened" or some sort.
My computer does have minor structural damage near the ventilation, but is absolutely fine with cooling regardless and no loss of function can really be linked to the damage. It has had rough exposure to the elements because I used to use the convenient touchscreen to use it while mobile, but now I can't do that.
My family never purchased a warranty. Worst decision ever, but good in some way -- I didn't pay those cretins any more than I needed to.
It appears there is no definable solution to this problem, but many solutions that could work or work temporarily.
We need statements from these companies, but we'll probably just have the blinds shut on us.

I personally think my issue came about from leaving the computer running for over two days. My daughter plugs her iPod in to charge before she goes to bed. I left the computer on two nights in a row so the iPod would fully charge. Normally it gets shut down every night. I'm guessing that the computer might have overheated or the iPod messed things up, even though she's had it since Christmas and we've never had a problem before. Regardless, I'm happy that I didn't have to spend days or months trying to figure out the problem.
My untechnical specs: eMachines desktop system (purchased 2007, hard drive replaced 2009); Windows Vista Home Premium; Canon MP160 printer
