It’s super weird that my ARC4 (latest aluminium version) sometimes will be recognised as “xxxx i2c”, although several unplug-replug will fix that. Also Serialosc 1.4 and 1.4.1 constantly crash my max the moment i plug my ARC4 in… I’m now using FTDI 2.4.2 and Serialosc 1.2a and it stops crashing my Max but the recognition problem still exist. I’m on El Capitan. Anyone know how to fix this or has the same issue here?
