[USBSTOR]
- Implement timer routine which checks for hung srbs, not yet activated - Stop timer when the device is stopped - Implement function to check if the attached device is a floppy device - Implement function to send read format capacity request - Implement missing hardware id / device id support for floppy - Add retry count parameter for debugging purposes - Tested in VBox + VmWare + RH svn path=/trunk/; revision=55659
