usb: Fix out of sync data toggle if a configured device is reconfigured 2020-09-04T14:41:22+00:00 Mathias Nyman mathias.nyman@linux.intel.com 2020-09-01T08:25:28+00:00 cfd54fa83a5068b61b7eb28d3c117d8354c74c7a Userspace drivers that use a SetConfiguration() request to "lightweight" reset an already configured usb device might cause data toggles to get out of sync between the device and host, and the device becomes unusable. The xHCI host requires endpoints to be dropped and added back to reset the toggle. If USB core notices the new configuration is the same as the current active configuration it will avoid these extra steps by calling usb_reset_configuration() instead of usb_set_configuration().
