Yeah, that lsusb sure is a strain on your eyes formatted like that.
I think that your Calibre can't make up its mind if that's PTP or MTP.

Mostly that's because of the stupid descriptors.
I really don't know why anybody uses ff:ff:00 (instead of 06:01:01)
I modified my kernel to fix that and I don't even use MTP.

Have you tried turning off ADB (in Developer Options) as a test?
Check in dmesg for -110 timeouts and general USB thrashing.
