Windows is just reporting what the driver tells it to report. Some things to try:
1. Replace the cable.
2. Replace the device.
3. If you have more than one device on the same channel, remove the second device. (If you're not using cable select, make sure your devices are jumpered correctly.)
4. If you are *not* running the latest version of the interface driver, try upgrading.
5. If you *are* running the latest version of the interface driver, try downgrading, starting with the previous version and moving down incrementally until the problem disappears. (If this fixes it, notify the vendor.)
Upgrading and downgrading the driver may not be as simple as installing a new driver. It may be part of bundle, and certain driver versions may be dependent on specific versions of other drivers or device information files. When in doubt, contact the vendor.
You could also try Microsoft's knowledge base, which is quite comprehensive, despite popular belief. If you have access to premier support, you'll get "Microsoft Confidential" information as well.
Also, there are no registry "hacks"--just documented and undocumented values. The registry isn't a mystical land off the edge of the map, beyond which there be dragons. It's just a big set of binary INI files that support multiple data types and access control. ;-)
