In windows, 8.1, I’m sending a vendor specific control request that looks like the following:
Broken down, this is what an example looks like where variable1 and variable2 can be 0-255 rq = fl_send_msg(0x42, 0x3, variable1, variable2, buf[1], 1, 500) The result is that the transfer fails with error code 87, “the parameter is incorrect”. usb log at the bottom of this mail. I’m not quite sure what I’m doing wrong, I don’t seem to have a problem on mac or linux. It’s only windows, and only seems to be 8.1. Anyone know what this could be? Thanks so much in advance.
