Additional Notes

JDUSB2 - Drivers for Lexar Jump Drives. This one works. It's a self extracting file that creates a folder named /jdusb2. Contains instructions and drivers. Instructions in html.

After extracting, plug in the drive and point the wizzard at the c:\jdusb2 folder and the drive installs flawlessly for win98/me and win95. Windows 2000/XP do not need these drivers as they are found by the OS.

This one works, forget the rest. Taken from www.lexar.com. While there check out the recall on Lexar Jump Drives too.
