    I get the following message after connecting the SANSA EXPRESS to my PC. "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." (But of course, clicking the message only tells you that it's an unknown device.)

    I tried with two more PC’s but it showing the same error msg.

    Please assist me, waiting for your sincere reply.

    If you have more that 1 usb port on your computer.. some are lower speeds than others. What ever you are tring to move to are from your computer may take a faster speed port..


I had same issue get a 2.0 usb hub and plug it into that it will work. I have two 400's and only one does it. Theyt know of the issue just blame it on the pc.

My Computer wont recognize the usb device for my me-0214 E-book

click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts

if you need more help with post a reply

hope it helps

I plug it to my computer and I get a message saying that USB Device Not Recognized. I Have plugged and unplugged about 50 times and I still can't get it to work.

Try installing a driver disc for it first or locate the driver for it. Then plug it in, or turn off your computer unplug the USB device then with computer unplugged from the wall hit the power button till it flashes or about 3-5 seconds is all then leave the USB device unplugged and restart the computer again get it up and settled down. Then put the USB in another USB port. Try this thanks for using FixYa John

I have a Kingston Data Traveler 8GB USB Flash Drive which I bought 4weeks ago. Whenever I plug it in one of my usb ports, i get a message which says "USB Device Not Recognized. One of the USB Devices...

The thumb drive might have some fault.
Plug it in other OS mainly windows XP and Linux.
If still same problem persists after tried in Linux, problem is with pen drive.
You can ask for a replacement from the dealer as it has guarantee for 5years.

Firelite 160gb HD not recognized

Make sure that there is no "HD protection", in which the hard drive can only be connected to one computer. Also, try going to google and searching for some drivers for your computer to download and install. Then try plugging your hard drive in again.
