Post 10.10 USB-Serial Converter needs reboot to work
Guys,
I have a PL2303 based USB-Serial converter that I use every day for my work (to connect via serial port to network devices)
Up until now it was working perfectly fine. After upgrading to 10.10, it simply will not work until I reboot my mac book air. It goes like this...
Plug in USB serial converter, connect to network device.
Start up iterm or terminal, check the device exists:
Carls-MacBook-Air:~ carlnewton$ ls /dev | grep 230
cu.PL2303-00001014
tty.PL2303-00001014
"screen" to the device using 9600 BAUD, as per the profile configured in my Iterm client:
screen /dev/tty.PL2303-00001014 9600
The screen is successful, but I get no output at all, just a flashing cursor.
I then unplug the serial, reboot my mac, plug it back in and it works fine. It will continue to work fine until my mac goes to sleep from inactivity, I put it to sleep or shut it down.
I then will have to reboot it again to get it to work.
Any ideas anyone? Im not sure how to troubleshoot this, the device exists, and looks no different in /dev when its working or when its not working, I have a cu. Device and a tty. device both times.
Thanks in advance!
MacBook Air, OS X Yosemite (10.10)
