I have a PCI card installed which gives this computer USB2 capability. My "memorex M flyer" flash drive works just fine except often after a few minutes of having it connected the computer gives me a message indicating it thinks I have removed the drive from the USB port when I haven't. This sometimes happens in the middle of transferring files, etc. I immediately restart the file transfer process and it recognizes the drive and the process goes for a minute or two then the same thing happens.Whats happening and what can I do about it?

USB2 cards are cheap, maybe yours is defective. Swap it out and see if it still fails. Clean contacts, check for frayed cables etc. Otherwise: Maybe your drive is sucking too much current and something shuts down via overheat. Try removing all other usb devices. Best

That sounds like good advice. But I neglected to mention that I have two almost identical win 98SE machines where I have inswtalled the same card and both act the same way. But I just ran across advice that said I should have disabled the legacy USB via CMOS. I have tried that in this one computer and I think that may have cured the problem. I have tried transferring a large bunch of files without having it act up during the process. Got my fingers crossed.. maybe it's fixed. ???

If you are using a USB keyboard and you disable that BIOS setting you won't be able to re-enter the BIOS with the USB keyboard. Possibly connecting the KB to the add in card would work, should that need arise.

Good point! In my case I am still using a PS-2 connection for the keyboard & mouse so I could safely do that without "painting myself into a corner". Incidently, I have been using the flash drive and so far the problem has not reappeared!. Actually think it's fixed!
