I `inherited' a Pentium 4 Intel WinXP computer that, although it will recognize a 1/2 GBFujiFilm Flash Drive, will not recognize a 1 GBLexar Jump Drive (JDSP1GB-04-500C).
I have called Lexar several times about this (an email to Support brought no response). Their suggestions were:
1] Go to Device Manager. Uninstall the "Unknown Device", unplug the Jumpdrive and restart the system and plug it back in.
2] Assign a Drive Letter: Go to Control Panel, Disk Management, Assign a new drive letter, find the device and make the assignment
Neither solution worked, followed as I described them here. It did not even show up in"Assign a new drive letter."

The info about the problem and the computer's USB ports and handling of the Lexar and the FujiFilm, as written to Lexar:
=========================================================
Dear Lexar Support,
I have a 1 GB Lexar JumpDrive (JDSP1GB-04-500C). I have recently acquired a Pentium IV, 1.5FHz computer with Windows XP Professional version 2002. I have used the Lexar in every computer (all WIN 2000 or WIN XP) I have come across without a problem. This computer only recognizes it as an "Unknown Device" on a USB port.
The computer has two USB ports.
Device Manager Details:
____________________________________________________________
The computer's Device Manager reports two USB host Controllers:
Device: Intel(rl 82801BA/BAM USB Universal Host Controller - 2442
using I/O range EF40-EF5F and IRQ 19. No conflicts reported.
Device: Intel(rl 82801BA/BAM USB Universal Host Controller - 2444
using I/O Range EF80-EF9F and IRQ 23. No conflicts reported.
They both use the drivers:
Windows\system32\drivers\usbhub.sys version 5.1.2600.1243 (xpsp2.030702-2125)
Windows\system32\drivers\usbport.sys version 5.1.2600.1243 (xpsp2.030702-2125)
Windows\system32\drivers\usbuhci.sys version 5.1.2600.1243 (xpsp2.030702-2125)
Windows\system32\drivers\usbui.dll version 5.1.2600.0 (xpclent.010817-1148)
It reports two USB Root Hubs. Under USB Root Hub Properties...
It reports these drivers:
Windows\system32\drivers\mlnxfltr.sys version 5.1.2600.0 by WinDDK
Windows\system32\drivers\usbd.sys version 5.1.2600.0 (XPXlient.010817-1148)
Windows\system32\drivers\usbhub.sys version 5.1.2600.1243 (xpsp2.030702-2125)
It reports the Lexar as an:
Unknown Device
with Power Required as 0 mA.
It reports (for example) another USB Flash Drive (a Fuji 500 MB) as a:
USB Mass Storage Device
with Power Required as 178mA.
This Fuji is reported as using the driver:
Windows\system32\drivers\USBSTOR.SYS version 5.1.2600.1106 (xpsp1.020828-1920)
