CM19a X10 Transceiver on Ubuntu 10.04

The CM19a is a USB based X10 Transceiver. This is a modified version of
the more popular CM11/CM11A/CM15/CM17 versions all of which have serial
interfaces

** All of this information is from :
http://www.cuddon.net/search/label/CM19a ** I'm only posting it here so
that I can find it again easily

1. The Python driver written by Andrew (www.cuddon.net), requires
sudo/root permissions. To make the USB driver work for any user, do the
below:

Add this to /etcudev/rules.d/cm19a.rules
#Allow all users to read and write to the CM19a X10 Transceiver (USB)
SYSFS{idVendor}=="0bc7", SYSFS{idProduct}=="0002", MODE="666"

2. Blacklist two modules (in 10.04) so that the CM19a is seen by the system:

Edit using vim or nano /etc/modprobe.d/blacklist.conf

Add the following two lines at the bottom of the file:

blacklist lirc_atiusb
blacklist ati_remote

Reboot the machine so that the modules are unloaded and the udev rules
are updated at the same time.
