USB/Memory Stick/CD drive problems

Archived from groups: microsoft.public.windowsxp.general (More info?)

I've read the other threads on usb problems and none have helped. Here's my
problem:
1. When I insert the memory stick, I can see "Removable Disk (F)" in
windows explorer. When I try to open it, I get the "insert disk into drive F"
message and nothing happens.
2. In device manager, I can see the iomega mini usb device listed under
disk drives and its properties says everything is ok. The mini also appears
under USB controllers as a USB Mass Storage Device.
3. This type of problem has also happened from time to time with my D (CD
drive) and E (DVD RW) drives.
4. Restarting the computer with the iomega mini in the usb port solves the
problem but when I remove it and re-insert it, the problem starts again.
Restarting the computer with a cd in the D drive also lets me see the
contents of the cd.
