Has anyone had any success using this for comms on debian6-19-04-2012?
I'm trying to connect a CrystalFontz 20x4+Keypad LCD http://www.crystalfontz.com/product/CFA635YYEKU and as soon as I try to access the port by the example C code (or LCDproc or LCD4linux) the Pi locks up - powercyling is the only way to get it working.
Here's what I've done so far:
Plugged the LCD into the PI & looked for the /var/log/messages entries to ensure the Pi can see the USB details - it mentions FTDI and ttyUSB0. I also used lsusb and lsmod to ensure the device had an entry.
I read on a UBUNTU forum that I had to add an entry to /etc/modules to assign the product to usbserial drivers...or something.
- Code: Select all
usbserial vendor=0x0403 product=0xfc0d

I also read that other Linux versions have crashed systems when ttyUSB0 was accessed.
Does anyone know how to get this working?
