Accessing USB
lazarus / 23-Operating Systems

Under the Oracle VM Virtual Box in a terminal window the command lsusb
returns what are supposed to be the USB ports with VID:PID numbers.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 80ee:0021 VirtualBox USB Tablet
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

These aren't what are actually on the PC running WIN-7 and the virtual
box.

Under Raspian it returns the real VID:PID of the USB devices and also
under Debian on a Beaglebone.

Under windows reading the registry can return the COM ports but the
USB VID:PID is harder to get at.

What I'd like is an approach to get the USB VID:PID and description
strings via Lazarus from any of the three target Operating systems. 
And then of course be able to open a USB COM port and read/write
form/to it.

Suggestions?
Thanks
John
