uChameleon Communication problems


I have a number of Linux scripts that access data from the uChameleon pins. To retrieve the data in the script I use:

echo "adc 1" > /dev/ttyUSB0
echo read LINE < /dev/ttyUSB0

All scripts used to work fine but now they hang when reading the data back from the device. (i.e. never reads the data from /dev/ file) This is only started in the last week.

Also if i setup and run a script that only reads the data in /dev/ttyUSB0 and prints to output, then open another terminal and send
echo "adc 1" > /dev/ttyUSB0
the value on pin 1 is displayed in the first terminal.

This is happening with 2 uChameleons

Any help appreciated
