Because hidpp_probe() calls hid_device_io_stop() across hid_connect(), incoming HID++ responses from the device are blocked and g920_get_config() times out with -ETIMEDOUT. Temporarily re-enable HID device I/O around g920_get_config() in hidpp_input_configured() so the hardware configuration queries receive their replies during input setup.
