  • OAK-D-CM4 Top USB no data - only power working

When connecting any USB device which uses data transmission, top USB port is not working. It is only providing power to the USB peripherals. Is it configurable with software or hardware limitation?

Hi @AnshumanFauzdar
I tested with both the old OS and the new one V10, but in both cases the usb device was detected. Which revision of the board do you have?

Thanks,
Jaka

    jakaskerl Where to check the board revision?

    In meantime which OS should I consider re-flashing from the link [Because it shows POE also]?

    I have this CM4 Module:

      Hi @AnshumanFauzdar
      You have revison 2 (R2M0E2). I tested on the same board and the R0 board and the usb seems to work as expected. I tried connecting the OAK device to it an running lsusb and seeing the connected device, which indicates that the data transmission works.

      How did you test it on your side? Maybe the cable is the problem, or that the dongle drivers (you have it plugged in on the image) need updates.

      Thanks,
      Jaka

        jakaskerl Thanks for the update, I flashed new image that is version 10 and now its working but still USB devices requiring higher current like waveshare touchscreen do not run but its okay in my use case scenario as I am utilizing lower one for higher power USB and upper one for Wi-Fi dongle.

        Thanks!
