Is there a way to set the backlight on/off? LCD2USB seems to offer contrast and brightness settings only.

I did: sudo pip install lcd2usb and then sudo python usblcd.py the result is: Traceback (most recent call last): File "usblcd.py", line 9, in <module> lcd = LCD() File "/usr/local/lib/python2.7/dist-packages/lcd2usb.py", line 69, in __init__ raise LCD2USBNotFound() lcd2usb.LCD2USBNotFound: Cound not find LCD2USB device.

It looks like that the device is not connected. Is there to do anything ealier ?
