I am trying to use the USB 3 OTG port on the ROCK3B (running debian 11 OS) as a USB HID keyboard on a windows device and I wanted to know if it’s possible.
I came across a thread on this forum which tried a similar thing but that was for a ROCK 3A board which used the ubuntu image.
One of the difference I became aware of is the configfs file system in ubuntu which I could not figure out for debian.
I would appreciate if someone can guide me in achieving this.
Thanks & Regards,
Yash
Update:
Using the radxa wiki guide for Debian dev I was able to successfully generate a kernel image & debian package of the 4.19.193-1 kernel image with USB-HID device drivers enabled. This modified kernel (image and headers) was installed on my existing debian image running on the rock3B. I have verified that the new kernel is running by running the uname -r
I have run into a new problem, where in now I cannot see any overlays when I run rsetup. It says “Unable to find any compatible overlay under /boot/dtbo” inside rsetup when I try to manage overlays or view overlay info. Even when I try to rebuild overlays it says overlay data has been successfully rebuilt but when I try to view overlay data it says the same thing (unable to find any comptabile…)
Apart from this, I have confirmed that
“/lib/modules/4.19.193-1-rockchip-g67a0c0ce87a0/kernel/drivers/usb/gadget/legacy/g_hid.ko”
and
“/lib/modules/4.19.193-1-rockchip-g67a0c0ce87a0/kernel/drivers/usb/gadget/function/usb_f_hid.ko”
both exist BUT when I try to
modprobe g_hid
I get “modprobe: ERROR: could not insert ‘g_hid’: No such device”
I am quite stuck. Any sort of help or direction would be most appreciated.
Thanks & Regards
I decided to uninstall the previously installed linux kernel and generate a fresh kernel image following the same guide as before. While installing the kernel on the rock 3b board using the dpkg command I received the following errors:

My build process is as follows:
I am building the u-boot, kernel and debia package on a virtual machine which runs debian 11.
I then rsync the files over ssh from the build machine to the target board (radxa rock 3 b) and then try and install the kernel packages…
Where am I going wrong?
