Uncommented that line. Testing with a USB stick. The stick is detected
fine in Debian, I can check it in Virtualbox's list of USB devices and
it is 'removed' from Debian and appears in the guest OS. All works fine.
I safely removed that stick and reconnected it and the behavior repeated
in the same way. All good.

Yes, they are the same.

Haven't tried that yet.

I think that I do. I will check shortly.

(see above), a USB stick works.
I tried Tomtom again. It is shown in the USB device's list, in the guest
OS, as:
Linux 2.6.28.10 with dwc_otg_pcd Tomtom [0327]
Once I check that to use it in the guest OS, it disappears and takes all
my USB detection and stuff from Debian too.
