UCSI specification quite clearly states that if a command
can't be completed in 10ms, the firmware must notify
about BUSY condition. Unfortunately almost none of the
platforms (the firmware on them) generate the BUSY
notification even if a command can't be completed in time.
The driver already considered that, and used a timeout
value of 5 seconds, but processing especially the alternate
mode discovery commands takes often considerable amount of
time from the firmware, much more than the 5 seconds. That
happens especially after bootup when devices are already
connected to the USB Type-C connector. For now on those
platforms the alternate mode discovery has simply failed
because of the timeout.
To improve the situation, increasing the timeout value for
the command completion to 1 minute. That should give enough
time for even the slowest firmware to process the commands.
