I bought a cheap VK-QF9700 to connect to my new Raspberry PI Zero. I know the chipset (DM9601) had some problems with the Raspbian kernel that has been recently updated.
The problem I have is that if I power on the Raspberry, wait for the boot to finish and then plug the Ethernet adapter in the Micro USB, everything works fine.
But if I leave the adapter plugged in and try to boot, the adapter does not get recognized.
rc.local to check if it is detected, but the command just shows me the standard USB Hub without any devices attached.
I tried resetting (with a utility I found around,
usbreset) the USB hub, but nothing happens.
