This only means that the kernel unsuccessfully tried to download digital 
photos from your Line6 device - nothing to worry about :-)

This indicates that you compiled the driver from the subversion sources, which 
are slightly different from the version in the kernel git repository. However, 
the differences between them are mostly cosmetic and should not cause the 
driver to work with one version and fail with the other. For the sake of 
completeness, you can try to use the driver module that comes installed with 
your kernel binaries (unless Linux Mint omits the staging drivers) or compile 
the driver from the git sources.

To make sure that a particular driver gets loaded, you can unload the current 
Line6 driver module ("rmmod line6usb") and load the new module by its absolute 
path ("insmod /path/to/line6/driver/line6sub.ko"). This is not persistent, 
i.e., when the kernel tries to automatically load the module (after a reboot 
or after unloading the module), it will always search in "/lib/modules/...".

Aside from that, as Stefan suggested, putting some "printk()" in the code and 
see in the system log file whether these statements are reached is probably 
the easiest way to figure out what's going wrong.
