Does anyone know if there is a way to set the MaxTransferSize for the control
Endpoint using USBD? I'm successfully selecting an interface with the desired
MaxTransferSize but when I do a Control-Write with a MaxTransferSize -sized
packet I'm get an int3 in the IOCallDriver() call and a
STATUS_INVALID_PARAMETER return from the call.
The MaxTransferSize of the selected interface is 8204 bytes but I'm only able
to send about 4k without the int3.
BTW. This is a dfu interface with no pipes (uses only EP0) so I can't just
set it in the pipe info
Any thoughts?
