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. Uint8_t reportId // Report ID = 0x4D (77) 'M' LED Indicator Page outputReport 4B (Device Host) On this endpoint: with an interval setting in the descriptor of 32, my device get tokens every 32 ms (stdev 50us).

#Wireshark usb interrupt windows 10
USBpcap 1.2.0.4 (via the current version of Wireshark 2.6.4) on Windows 10 圆4 shows all sorts of useful traffic: USBCONTROL out, SET CONFIGURATION Status, USBINTERRUPT in. Keyboard/Keypad Page inputReport 4B (Device -> Host) Turns out it's being captured but either the capture is wonky or Wireshark is incorrectly displaying this data. If you want to also decode the HID report descriptors then use the "-d" option. Field name Description Type Versions usb.addr: Source or Destination: Character string: 2.0.0 to 3.6.8: usb. It will by default print the C-structures (see below).
#Wireshark usb interrupt software
Now run the decoding software and paste the hex stream after the "-c" option.
#Wireshark usb interrupt code
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. Wireshark can also sniff USB traffic so I thought it would be At this stage Ill try.
