The USB CDC driver is unable to process any bulk IN transfers after receiving spurious 'Clear Feature - Endpoint Halt' request from host due to perpetual locked state caused by previously scheduled transfer, that will never be finished, as the endpoint's state is set to NAK. Fix by ignoring spurious request. Signed-off-by: Piotr Ciura <[email protected]> (cherry picked from commit 29a191a)
