Fix documentation of lsusb behaviour

[Crote]

The documentation did not accurately reflect the behaviour of lsusb , which might result in minor confusion.

Description

On Fedora 32 (and I assume most other distributions), lsusb will display the configured MANUFACTURER and PRODUCT if the database does not contain entries for the VENDOR_ID and PRODUCT_ID used. Considering the DB does not contain any entries for the vendor 0xFEED, it should just display the values as advertised by the device.

Similarly, doing a lsusb -v will not show those values, as it seems that a regular user does not have the required permissions to read them. It will just leave the field empty. Doing a sudo lsusb -v fixes this.

This needs to be rebased.

It has been rebased.

I think you can safely target the master branch with this change as it is not breaking.
The change needs to be properly rebased first, though.
