Subject: [PATCH] staging: vt6656: call usb_device_reset before netdev registration
Date: Tue, 22 Oct 2013 20:00:22 +0100	[thread overview]
Message-ID: <1382468422.6472.8.camel@canaries64-MCP7A> (raw)

The USB reset occurs after netdev registration if network manager
calls device_open too fast causing USB fails in main_usb.c: device_init_registers.

Move the usb reset to before register_netdev.
