I'm having a similar, but unique, problem with my USB drives. If I use a USB device that requires a program interface (i.e., it's not a drag and drop device) then I have no problem getting my computer to recognize it. But if I use something like an SD memory card reader, that's when I run into a problem. However, my computer DOES recognize that the device is there. I get a popup notification in the system tray saying "found new device" and I have the button which allows me to "safely stop device." But if I go into "My Computer" and try to open the device to view the contents, it doesn't show up in the list of available drives.

I will try the fix described by n10city since it talks about "hidden devices", but thought someone might have another idea as well.

Thanks!

EDIT: I forgot to mention that I'm running Windows XP Home (SP2)

CJTucker,

What did u do to make the USB recognize the printer? I have a Color Laserjet 1500L printer and it's plugged into the USB port of the XP box however it's not printing anything. I use the USB device when adding printer(u know, lptr, serial, usb, etc). It did not come up with an error when I added that printer using the usb port but it's not printing at all. Suggestion?

Vincent
