Hi, I can send input/output report request via HID interface, using the following command: dev.ctrl_transfer(0xA1, 0x01, 0x0100|reportId, hidItfaceIdx, reportLen) dev.ctrl_transfer(0x21, 0x09, 0x0200|report[0], hidItfaceIdx, report)
but failed to send feature report request: dev.ctrl_transfer(0xA1, 0x01, 0x0300|reportId, hidItfaceIdx, reportLen) dev.ctrl_transfer(0x21, 0x09, 0x0300|report[0], hidItfaceIdx, report) I tried the above command in MS-Window, using libusb as backend.Is there any restrictions on this usage? Thanks.
