GadgetFS disables keyboard/mouse #331

Closed jiajun78 closed 6 years ago

jiajun78 commented 6 years ago

Hi,

I have encountered some issues using gadgetfs on the Intel Aero Compute Board.

My setup is as follows: OS: ubuntu 16.04 Kernel: 4.4.76-aero-1.2 I downloaded the kernel source from https://github.com/intel-aero/linux-kernel Using the config from https://github.com/intel-aero/meta-intel-aero-base/blob/master/recipes-kernel/linux/linux-yocto/defconfig

I configured the kernel to use gadgetfs instead of ethernet gadget (g_ether).

On boot, the mouse and keyboard will not work at the Ubuntu login screen.

This is rather odd. Using a kernel with g_ether instead of gadgetfs will not encounter this problem. This seems to be an issue with gadgetfs on the board.

Any help is appreciated.

No one have tried this and I'm not sure if the driver supports it: https://github.com/intel-aero/linux-kernel/commit/9c7592a46553ca8bfcd02f204e6db8bd8380eca0 Maybe if you backport the upstream driver to Aero kernel(4.4) it might work.

Managed to solve the issue using kernel 4.4.76-aero-1.2

It was due to a bug in the userspace gadget driver ..

Thanks
