This doesn't change anything, the device fails to attach.

Do you have some ideas how this situation could be handled in the new stack?

Yes, this module is loaded and I can see it enters the probe routine. But as
the configuration index doesn't match what the driver expects it fails to probe.
Driver checks for configuration idx 1, but I see this device on idx 0.
ugen0.2: <AnyDATA CDMA Products AnyDATA Corporation> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

The old stack didn't checked for specific configuration index, but tryed to select
the appropriate one in the attach routine.
        /* Move the device into the configured state. */
        err = usbd_set_config_index(dev, UBSA_CONFIG_INDEX, 1);

What is the reason you have reworked this? Should this be changed to be handled
like in the old driver?

Thanks!
