Hi mr_bigmouth_502,
the utility usb_modeswitch is available in our repos, simply start Synaptic (package manager), click on Reload, Mark all updates, Search [usb_modeswitch], select the two packages, click Apply and Apply.
usb_modeswitch-1.1.8-1pclos2011
usb_modeswitch-data-20110619-1pclos2011
then try to follow the link you posted, remember that PCLinuxOS doesn't use
sudo, instead before to use commands that would require sudo, simply type
su (or "
su -", depending on current setup of LXDE), followed by your root password, then type the required commands.
Good luck!
AS
