The driver was issuing synchronous uninterruptible control requests without using a timeout. This could lead to the driver hanging on probe due to a malfunctioning (or malicious) device until the device is physically disconnected. While sleeping in probe the driver prevents other devices connected to the same hub from being added to (or removed from) the bus. The USB upper limit of five seconds per request should be more than enough. Fixes: 99f83c9c ("[PATCH] USB: add driver for Keyspan Digital Remote") Signed-off-by:
