Who is the mfg. of the device? Did you look at their website for drivers?
My Lexar shows in My Computer as Lexar Media (G)
But I have to install drivers when attempting to use on any older OS than XP.
As with any hardware, Windows may not automatically install the correct drivers.
Check in the device manager under disk drives to see the status of the device. If it's listed there, double click on it to see the status. Look for the yellow ? or !.
Best of Luck
I have tried connecting my 128MB flash USB pen drive to my USB (1.0) port (I tried both ports). XP Pro SP2 sees it and installs it, but I don't see it as a drive in Win Explorer or My Computer. "Safely Remove Hardware" shows it as a Generic Volume (G), but the only other place I can acknowledge its presence is in Internet Explorer. This P3 800Mhz PC is an upgrade from W98SE (9 months ago). It is fully patched, and otherwise functioning normally. Mboard is an Asus p2B-F with the last available bios upgrade. I am unable to do a clean re-install of XP Pro at present. Is there a technical workaround in the registry for this? I have experenced the same problem trying to hook up an external Firewire drive. Thanks for any help and advice.. Jay
