Flash drive problems.

[loki80]

I have a 256MB kingmax flash drive. When I inserted my flash drive in to my notebook computer, it was detected and ready for use. But, when i inserted it to my desktop computer (pentium IV, mainboard Intel), it was detected and show message "but i can't access it, and appeared a error "USB device not recognized". On the device manager, it's listed on Unknown device. My notebook computer has USB 1.1 ,desktop computer has USB 2.0. Then I disable a Universal Serial bus controllers "Intel(R) 82801DB/DBM USB 2.0 Enhanced host controller - 24CD" on Device manager, and my flash drive works fine. I don't know why, anybody please help me!

Did you restart the PC ?

Some PCs don`t recognize some USB flash drives automatically.

You just have to install/reinstall/restart manually.At least that`s my experience.

do you have service pack 2? Are you running XP?
The drivers for your flash drive probably aren't recognized.

It's only don't recognized with USB 2.0 port. USB 1.0 and 1.1 work fine

My flash drive uses USB 2.0, winxp SP2 isn't a problem. I thinks the problem's USB 2.0 on device manager, when i disable USB 2.0 port, my flash drive works fine.
