From: Andrey Konovalov <[email protected]>
During device operation, the host might decide to reset a device emulated
via Raw Gadget. In this case, if the device emulation code has endpoint
requests queued, usb_ep_queue will fail with -ESHUTDOWN. Currently, this
disables the Raw Gadget device and makes the emulation code unable to
proceed.
Do not disable the Raw Gadget device if usb_ep_queue fails.
