Log:
[USBHUB_NEW]
- Implement constructing CompatibleIds string using device descriptor. However, if the
Class of the device descriptor is 0, then Class, SubClass and Prot which make up this
string must come from the Interface.
- Change Ids and Descriptions to Unicode Strings.
- Move the creating of Id strings to one place, CreateDeviceIds, and called it at device
creation.
