    USB hub not working on OdroidC2

    Hi Guidol, Thanks for replying. I am not using an external usb-hub rather the usb-hub of the odroicdc2. None of the USB peripherals connected to the ports o f the hub are detected by the OS. I tried connecting a barcode scanner and a ZTE USB modem. None of them were detected in lsusb. Thanks Sumit

    USB hub not working on OdroidC2

    Hi @TonyMac32, Thank you so much for replying. This is the link to the output of `armbianmonitor -U` : https://pastebin.com/7VS5BzZ4 Couldn't upload debug info using armbianmonitor -u as the usb hub is not working I couldn't connect the device to the internet through USB Modem. Thanks again. Sumit
  4. I used a stable Armbian Image (Armbian Stretch mainline kernel 4.18.y) for OdroidC2. The OS booted up normally but the USB hubs didn't detect the connected peripherals. The output of `lsusb` didn't show any of the connected peripherals. Thanks Sumit
  5. Solved the problem (edited) Disabled usb gadget service of orangepi zero `sudo /sbin/rmmod g_serial` (edited) then `sudo bash create-gadget.sh` link to solution: https://vjordan.info/log/fpga/nanopi-neo-usb-otg-with-armbian-mainline-4x-kernel.html after `rmmod g_serial` , it can be verified on the host pc by `lsmod`. On the orangepi: `ls /dev/hid*` lists the hid device ports (hidraw1, hadraw2 ... ) and gadget port (hidg0)
  6. I want to load my custom service to show orangepi zero as three devices on the host PC. But as the UDC ( /sys/class/udc/musb-hdrc.1.auto) is being used by another service which is probably the builtin service using udc to show orangepi as: Bus 001 Device 048: ID 0525:a4a7 Netchip Technology, Inc. Linux-USB Serial Gadget (CDC ACM mode) I want to disable that service so that my custom service can use the UDC for the required purpose. This is the command: echo "$(ls /sys/class/udc/)" > UDC and this is the error: echo: write error: Device or resource busy "ls /sys/class/udc" has the file musb-hdrc.1.auto and UDC is in the folder /sys/kernel/config/usb-gadget/< custom name>/ , which is created using a bash script Regards, Sumit
