force the reload of udev rules:
sudo cp ./51-gqgmc.rules /etc/udev/rules.d/51-gqgmc.rules
sudo udevadm control --reload-rules
Disconnect the GQ GMC-300 from the computer and then reconnect.
Verify that there exists a /dev/gqgmc in the /dev directory with
read/write permission for all users.
ls -la /dev/gqgmc
6b. With the GQ geiger counter connected to your PC via USB and turned
on, start either bin/gqgmc or bin/gqgmc_gui from a console command
line. However, you must supply the device name of the USB port on
the command line, for example on Ubuntu 11.10 try
"bin/gqgmc /dev/usb/ttyUSB0". On Ubuntu 12.04 try
"bin/gqgmc /dev/ttyUSB0".
You can try to identify USB port using the following scheme.
(a) Before plugging in the GMC-300, run the command "dir /dev/ttyUSB*".
Take note of what, if any, devices are listed. After plugging
in the GMC-300 and turning it on, wait one minute,
then run the command line command "lsusb". You should see a line
with "Prolific Technology Inc." at the end of the line. This
indicates that Linux has successfully recognized and setup a port
for the GMC-300. Now try the command line command "dir /dev/ttyUSB*".
The device name for the GMC-300 should be the newest port added
to the previous listing of the same command. (On Ubuntu 11.10,
try changing /dev/ttyUSB* to /dev/usb/ttyUSB*)
line. The USB device name must be supplied from the command line, e.g.,
bin/gqgmc /dev/gqgmc
bin/gqgmc_gui /dev/gqgmc
The code expects the GQ GMC USB device name to be /dev/gqgmc. This
device name was created at step 6a.
