My shuttle control was working fine out of the box with the supplied cable before the update, not sure if theres something on the shuttle system that is different, you could try to mess with the settings and make sure there arenāt any midi loops happening.
In my config, OP-Z is the master clock sending pulses to Shuttle Control. Sometimes I have had to replug the USB cable on the OP-Z end to make sure the correct midi relationship is established before it starts to work (Since Z can be host or slave).
Ive never had the Z lock up in this situation thoughā¦
