I've been having no luck getting low-speed USB devices (i.e.: keyboard and mouse) to work with the 4.4 96boards kernel on hikey. My ethernet dongle works fine though. Is there a known problem or do I maybe just have a config issue? The error messages are:
device descriptor read/64, error -71
and
device not accepting address 7, error -71
Did you leave the USB dongle plugged in? IIRC Hikey cannot support a mixture of high speed and low/full speed devices simultaneously.
the following command should set the controller to full speed
$ echo 1 > /sys/kernel/debug/f72c0000.usb/config
That file does not exist in that directory.
