Hi Charles, Thanks The device was created on Ti TMS320c6747 using BIOS USB pcakage (based on JUNGO USB stack). I am not sure which method it respond. re-run lsusb seems gotting correct report descriptor libhid test result: TRACE: hid_prepare_hid_descriptor(): retrieving HID descriptor for USB device 008/002[0]...
