When I repeatedly open and close ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3 several times, errors will occur.
All the ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3 devices can no longer be open agin, Here is the error message：
[ 185.127665] cp210x ttyUSB2: failed set request 0x0 status: -110
The requested massage is sent through this usb_control_msg() API
Please help me, what causes it and how to repair it.
