![]() ![]() The "Leftover Capture Data" should contain the payload as described by one of the C structures. Now that you have a clear idea of the possible reports that may be flowing, you can go back to your Wireshark trace (still filtered on "usb.request_in") and select "URB_INTERRUPT in" packets. ![]() Int8_t GD_MousePointerX // Usage 0x00010030: X, Value = -127 to 127 How to capture USB data and filter - How to capture USB traffic TimVT971 194 subscribers Subscribe 18K views 2 years ago Show more USB in Wireshark: Stealing.

It will by default print the C-structures (see below). Now run the decoding software and paste the hex stream after the "-c" option. right-click the "HID Report" and choose "Copy" and ".as a Hex Stream".select the "GET DESCRIPTOR Response HID Report" packet.I wrote a bit of code a while back to help me decode HID report descriptors and to create C language structure definitions to describe each report. ![]()
