Today I was locked in my house due to having a slight case of the flu. During the times I wasn't sleeping and drinking Nyquil by the gallons I actually got my Visor USB device to syncronize with Linux. Follow my easy setup tips and join in on the fun.
The quick and dirty Setup
The first thing is to use kernel 2.4test? or use the latest stable release (currently 2.2.18). When you get to the USB section add the visor via a module and be sure you choose the correct driver for you motherboard. After you get the recompile done, reboot your machine and add the following USB devices:
mknod /dev/ttyUSB0 c 188 0
mknow /dev/ttyUSB1 c 188 1
etc....
cd /dev/
ln -s /dev/ttyUSB1 visor
You will won't to make at least 15 of the ttyUSB's that is just what the docs say).
Next, "insmod visor" and install the next pilot-link software. Be sure that you setup the pilot-link software since that is what does all of the transfering of your files from Jpilot. Next, install Jpilot, setup your preferences. Press the sync button, and then sync in jpilot. Enjoy!
