2011-10-19Android : Ux500 : USB :Resetting the endpointsSakethram Bommisetti
USB endpoints are not being reset at the time of disabling the functions. Due to this, the endpoint data is not freed. So, during re-assignment of EP's for a new USB configuration, some of EP's are skipped.

2011-06-14USB: gadget: android Fix gadget descriptor compliance for IAD'sJohn Michelau
USB-IF core team mandates that composite devices containing IAD's must use bDeviceClass=0xEF, bDeviceSubClass=0x02, & bDeviceProtocol=0x01 instead of the usual 0x00 in all fields. This is not a problem currently on Linux hosts, but it is a problem when connecting to Windows hosts. Without this change the default Microsoft composite driver will not group interfaces properly, which is what allows child function drivers with IAD's to load correctly.
