New usb flash memory driver, now CDROM not working 100%

Just downloaded and installed USB flash memory driver for Kingston Data Traveler. Now some of my programs won't recognize the CD-ROM (Magellan TOPO USA now tries to access the flash memory instead of the CD-ROM).

Device manager doesn't show any problems with CD-ROM

System is an older PC

OS is Windows 98SE.

Hard drive is partitioned: C: D: E: F:

CD-ROM is Drive G:

Flash Memory when pluged in is Drive H:

2 port USB Card added to mother board and has worked fine with scanner and cheapy digital camera usb connections.

USB flash memory works OK (files access, copying, etc.)

Any help or suggestions to get system to not confuse drives would be appreciated.
