Install blinkstick on Slacware

I recently built a blinkstick, a cool little device. Using it under linux is very easy using the command line, but I had some issues installing it under Slackware:

pip install blinkstick

Apparently my version of pip would not install pyusb by default, so I had to do:

pip install -pre blinkstick

I plan to use it in my hp microserver behind the logo so I can glance server and raid status, as the default rgb led broke in mine and it also only turned red for fan or other hardware issues. What for would you use yours?
