Hi Geeks!
I’m here to get another problem solved…
I’ve just bought a Kingston 4GB DT100 USB flash drive. The problem is, that when I connect it to my laptop, a popup notification appears in the notification area, saying “USB device not recognized”
When I pop the balloon (click it), a window appears telling that this device is unknown
Now what…?

I went to my friend, who has almost the same laptop as mine (Latitude C660). The laptop didn’t recognize it.
But then, he did this (and asked me to do the same):

Attach the USB first
1. Open device manager, click “Universal Serial Bus controllers”
2. Uninstall “USB root hub”
3. Click Action>Scan for hardware changes
4. The USB root hub comes back
5. Restart the system
After restarting, the USB was working fine…

I did the same on my system, and guess what, it didn’t work…

So now what do I need to do in order to get the USB running?
Thanks in advance (as usual)!

Support information:
Hardware: Dell Latitude C610 with only one USB port available (not USB 2.0, it’s lesser than 2.0)

O/S: Windows XP professional SP2

Hatryst, your friend may be onto something. See the following article by The Geek:
http://www.howtogeek.com/howto.....-hardware/

Remove the flash drive from your system, then use the technique in that article to remove any hidden (greyed out) USB devices in Device Manager. Do also remove any entries for the Kingston flash drive. Remove the USB hubs, but don't scan for changes. Restart the system and Windows should rediscover the USB hubs and restore them in Dev Mgr. Now, try the flash drive to see if it is detected and works.

Well, removing the USB hub removes the driver for the wireless phone (which i'm using to connect to the web!)
I'll post back soon...

Keep more solutions coming...

ScottW, i saw the link, and did as told... but it didn't work

Let me make myself more clear. The PC doesn't recognize what type of device is attached to it. It doesn't know whether it is a mass storage device or what. It just shows the message:

As you said Do also remove any entries for the Kingston flash drive, there were no entries for kingston flash drive, since it is not recognized...

Hatryst, well it was worth a try since it worked for your friend. There are some KB articles at Microsoft that might help or try the USBMan's troubleshooting tips:

@Hatryst,
$8.00 bucks at New-egg plus a ribbon cable of course.

Always advise all Builders to include one in their Builds. Almost a NO cost item.
Very, very convenient for doing many, many things on big machines.
Regards,
Rick P.

Yep, if you want to boot a machine in Dos or DosPE with a Ram Drive, easy way to get the job done fast.
Boot CDs are also Great.

I changed the RAM in my Dell Lat. C610 from 2x128mb to 1x512mb and my Kingston 8GB usb drive wouldn't work. I found that for some reason this Dell won't take 1024mbs of RAM like Dell says it will. When I put the 2x128mb sticks back in, my USB worked again. Not sure why but it did.
