Hi,
I am using the CA-USB2-MTi cable to connect my MTi-30 (MTi-2A8G4, sn: 0368204E) to my laptop.

I can't launch ros node. The error is the same as mentioned in #36
TypeError: ord() expected a character, but string of length 0 found
If using the normal accompanying USB cable, everything works just fine.

Because I need to use SyncIn so USB-to-serial is the only choice I have.

I also try to reduce the rate to 80Hz, 50Hz as in #43 to see if I can avoid it but the problem persists.

@StevenXsens in #43 said that there is some troubles with the FTDI chip, I wonder if the problem has been resolved?
If the ROS driver is not ready, is there any workaround that I can try @arunvydhya?

The problem is solved with the new ROS driver accompanied the latest MTi Software Suite.
