Has anyone actually built this driver in a while?
thanks,

Hi,
I have build and loaded the driver. To me this seems OK.
dmesg from loading:
usb_skeleton: loading out-of-tree module taints kernel.
usb_skeleton: module verification failed: signature and/or required key
missing - tainting kernel
usbcore: registered new interface driver skeleton
dmesg from unloading:
usbcore: deregistering interface driver skeleton
Used kernel 5.15.0-rc1+
Bye Philipp
