If I understand the code from hid-core.c correctly, usbhid_output_report sends the report using the interrupt out pipe instead of a control transfer. Check if the USB descriptor for your device declares an interrupt out endpoint and use it if it exists. > > Thanks in advance. > > Manuel > > > My current code, which does *not* work, follows.
