The new is that the driver is not allowed to set the config index by itself.


usbconfig -u 0 -a 2 set_config 1

You can for example add a quirk for this, see "usbconfig -h | grep -i quirk". 
I know this is not so easy, but if you can make a general rule for when 
selecting another configuration, I will add it.

Could you dump me the descriptors of your USB device?

usbconfig -u 0 -a 2 dump_curr_config_desc dump_device_desc
