Vista Troubleshooting

I posted this in installation as well but I thought I'd post here as it is also a troubleshooting issue.
The Vista drivers will install and Vista says the USB-UIRT is working properly yet no program, even lrnhelper, will see the USB-UIRT.
Works fine under XP, but not Vista (on my 32 or 64 machines).
Anyone else have an issue running USB-UIRT under Vista or can make any suggestions?
Thanks in advance for any help.
