There is a very good PCs still have USB2 ports. They are reliable. The always work. Before an OS loads, getting usb3 ports working is iffy. Manufacturers rarely fix their implementation in firmware so you’d want to boot that Linux distro on that Dell or HP laptop and start with usb2.
Usb3 also causes interference with wireless transmitters
Oh god I hate this so much. The proliferation of USB 3.0 devices in the office has made 2.4 GHz keyboard and mice nearly unusable. I'd much rather they change the frequency to fix this than whatever thunderbolt stuff they're dealing with right now
That interference doesn’t span an entire office. Simply place the transmitter in a USB2 port or get a short usb2 extension cord and put the transmitter in that, giving it some distance from the usb3 port.
This does get me thinking there is an attack you can pull on machines with USB3 ports where the signals emitted by the ports could be picked up further away and be used to break an airgap.
