Hi, I'm trying to reverse engineering something with a windows driver, but I'm having trouble replicating one of the reads it makes with pyUSB.
The driver sends a read-request on each endpoint, with different wValue, wIndex and wLength fields set. I can see how to do this on the control channel with pyUSB (using dev.ctrl_transfer), but I can't see how to set these if I'm doing a read request as that just takes a length... The driver packet looks like this in wireshark: ... Endpoint: 0x80, Direction: IN <snip> URB: bmRequestType: 0xc0 bRequest: 4 wValue: 0x0040 wIndex: 0 (0x0000) wLength: 8 I'm not sure if I'm missing something about how USB works, or how pyUSB works....any pointers much appreciated! Thanks, Joel
