![]() ![]() I am also trying to get my system to work with a Contour Shuttle Xpress USB jog and shuttle wheel. If I open more than one card the keyboard stops responding. However, with updated versions of Raspbian I can only use one 4-port card at a time. I have used the system at my day job to control banks of video recorders, and have left the system talking to itself on another RasPi for days on end without problems. These are on three FTDI USB-COM422-PLUS4 cards. With an early version of Raspbian, 3.1.9 #168 from 14th July, I can reliably open and read/write twelve RS422 serial ports. However, later versions of the operating system seem to give more problems. I have been working on a USB to serial project on the RasPi for some months now, with quite a lot of success. )Ībcdfghiijjjjjjjjklllmnopqrstuvwxyz123467890-= Tral fterusb ull ( caused the previous txt to be ovewritten with BS.
