Print info about devices we can control power on if possible

Browse Source 
Print information about connected devices in following format:
[VID:PID Vendor Product SerialNumber].
However, some of these items may be skipped if they are not possible to obtain.
For example, on Linux, VID:PID should always work, but getting Vendor/Product/SerialNumber
requires having udev permissions for USB devices in question or running uhubctl as root.
