Here's an update. I got it working now, but have been unable to crack Microsoft's anti-driver download firewall. Talked with the product manager at Belkin, and he at least got me running with no BSODs. I deleted the OrangeMicro USB 2.0 Controller, and then deleted all of the old OM driver files from SYSTEM32\DRIVERS.
I also downloaded a new OM driver set for USB 2.0. With that, I rebooted and it found the controller . . . and the new OM driver INF file made it end up as a "NEC PCI to USB Enhanced Controller B0." I then added the new Belkin hub, and it installed as a Generic USB hib on that controller. So far it all works, but I don't think it is USB.
According to the Belkin tech, the only way to get the Windows Update site to provide any sort of clue as to a new USB driver, it is necessary to go there with nothing related to USB installed or in use. That sounds wierd . . . but this whole thing is wierd. I just wish M$ would post drivers in a library . . . go to their catalog under USB 2.0 and you end up with nada as well.
Viva Firewire! I am now convinced to forget about a USB 2.0 CDRW and get another Firewire one.
