Possibly because of the changes in usbhid/hid-core.c the first
raw input report is not received during ccp_probe function and it will timeout.
I am not sure, whether this behaviour is expected after hid_device_io_start or
if I
am missing something.
As a solution this adds msleep(50) to ccp_probe so that all initial input
reports can
be received.
