New Revision: 51582
URL: http://svn.reactos.org/svn/reactos?rev=51582&view=rev
Log:
[USBSTOR]
- Make DeviceId generation to match ms usbstor
- Don't hardcode the device type in USBSTOR_PdoHandleQueryHardwareId
- Don't hardcode device type in USBSTOR_PdoHandleQueryCompatibleId
- Hackfix generation of instance id
- Add comments
- Cleanup code
- Usbstor now receives ioctl from disk.sys
