Resetting the host endpoint may immediately restart any pending transfers for that endpoint. If the device endpoint halt has not yet been cleared, then this will probably result in a second failed transfer. This second failure may be detected within usb_endpoint_reset() while waiting for usb_clear_feature() to complete. The endpoint will subsequently be removed from the list of halted endpoints, causing the second failure to be effectively ignored and leaving the host endpoint in a permanently halted state. Fix by deferring the host endpoint reset until after the device endpoint is ready to accept new transfers. Signed-off-by: Michael Brown <mcb30@ipxe.org>
