Problem
After #2625 it seems that the Realtek SDK has new behavior again and doesn't pass even more interface requests to setup request callback.
Solution
Fake/force it to pass those requests by patching in wrapper
__wrap_usb_hal_read_packet
withbmRequestTypeType
=SetupRequest::TYPE_CLASS
. This for some reasons makes the SDK deliver these requests to our setup request callback.Steps to Test
Build bootloader, go into DFU, test that
dfu-util -d 2b04:d020 -a 1 -s 3106:192 -U p2.der
works fine (involves SET_INTERFACE request).Example App
