Here's the output for lsusb -v, with the Sony plugged in under uhci:

Unless I disable uhci, all I get from dmesg is:

usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: configuration #1 chosen from 1 choice

I never get enough information to try mounting it. If I disable uhci,
then one of the other usb modules takes over and the Sony gets assigned
a device, but no amount of guessing would allow me to mount it. If as
you say it's a proprietary internal filesystem, well, that's that.
