David,

This doesn't look right.

usb_get_configuration_no() is being passed tmpbuf which is the device
descriptor just been retrieved from usb_get_descriptor(), but now you
are mallocing a 9 byte buffer and won't contain that information.

What was the size of the configuration descriptor you saw ?

Also can we check what Linux does here ?
