This helps. Now ubsa attaches to the device. But I can't communicate
with it (no echo even). I see the following messages in the log:
ubsa_cfg_request:395: device request failed, err=USB_ERR_STALLED (ignored)
ubsa_cfg_request:395: device request failed, err=USB_ERR_STALLED (ignored)
ubsa_cfg_request:395: device request failed, err=USB_ERR_STALLED (ignored)

Why not let the driver to set the config?
