I have a laptop and a desktop, both XP Service Pack 3, both Dell. I bought a couple Sandisk USB flash drives and an HP flash drive. Plugged one into the laptop, worked fine, copied some files onto it, then plugged it into the desktop, the light on the flash drive came on for a second and then went out, drive is unrecognized. Did the reverse with one of the other flash drives, used first on the desktop and then plugged into the laptop, same thing, light came on then off, drive unrecognized. Once this happens, that USB port becomes unusable for anything until the PC is rebooted. I now have flash drives that work on one PC and not the other. Any ideas what could be causing this and what the solution might be?

You can try to force it to recognize the flash drive in the Device Manager.

Go to Start> Run and type in devmgmt.msc and press the Enter key.

When the Device Manager opens right click on Computer. When this opens click on Scan for hardware changes.

Other options to try can be found in this Microsoft Support article.
