gadget devices

Unread post by odroid-C2 » Tue Jan 22, 2019 3:51 pm

I am currently trying to set up the gadget devices: HID, mass-storage, Ethernet and serial adapter
I got the HID gadget working, but then it stopped working after a kernel update.
On the updated version of the kernel I can run the mass-storage, serial adapter and Ethernet with no error messages. When I look at dmesg on my computer which is connected to the odroid, it detects the devices but does not set them up properly. If I run all of the gadgets together (including the HID gadget) I get the error message: "ls: write error: No such device"
Any idea what could be causing these errors?
Thank-you

We tested some basic Gadget drivers functionality on Ubuntu with Kernel 3.14 and 3.16 only.

I have no idea how USB drivers work in Kernel 4.x with S905 CPU. Sorry.
