Thanks for the data! I was hoping to see a different response to the version 
request code (F0 7E 7F 06 01 F7), which could simply be detected, but there 
doesn't seem to be any response at all. You mentioned that you successfully 
used the driver 2 years ago, so it would be useful to have the logs (with 
"dump control messages" enabled) of this old version. It might be difficult, 
though, to compile it, since the Linux kernel has changed a lot since then, 
and the Line6 driver changed accordingly. If you succeed, please provide the 
logs and let me know whether the driver special file "firmware_version" 
contains the correct value.

Another debugging option is to record the USB traffic under Windows with the 
original Line6 driver by some USB logging software. Somewhere during 
initialization, the firmware version number should be transmitted, though this 
is somewhat of a needle-in-a-haystack problem.

Do you have a Variax guitar connected to the PODxt Live via the Variax digital 
cable? Don't know if it is relevant, just to make sure we have the same setup.
