As you may remember, I’ve been trying to get my line6 audio interface working in fedorajam. So, I found a topic in this site linuxmao that led me to a mailing list from the developer https://sourceforge.net/p/line6linux/mailman/line6linux-user/ 

Looking through it, I find several users complaining that the driver broke at about kernel 3.2. The dev says it’s a change to the linux driver spec for usb that causes it, and he declines to fix it. I’m guessing this is why I couldn’t find the driver in Debian, they’ve been purging old drivers. 

At a minimum it affects these products: 

BassPODxt 
BassPODxt Live 
BassPODxt Pro 
GuitarPort 
PODxt 
PODxt Live 
PODxt Pro 
Pod Studio GX 
Pod Studio UX1 
Pod Studio UX2 
Pocket POD 
TonePort GX 
TonePort UX1 
TonePort UX2 

Now I see why the liveusb for KXStudio is ubuntu 14.04 - (kernel 3.13?). So, I tried that, and my rig works fine on it. Not that I want to use something past it’s EOL. I’m also not replacing all my Line6 equipment. Aside from the cost, it would break my sound, I’d have to start all over again building my sound. Nope.  

I'll stick with what is working.
