More information please: what sort of device is it? make / model? You say it's a controller, and then it's a device - which one is it? Maybe upload the inf as well.

Controller is a AT91SAM7S64. Device software return obtained bytes only. I create .inf by VISA Driver Wizard, but Windows say error (Code 10) and MAX can't see new USB device

I have USB controller with known VID & PID (Windows detect)

Visa Driver Wizard create .inf, but Windows can't use device with this driver (Code 10) and MAX can't see new device...
