Does using PS/2 adapter fully safeguard against USB related risks?

It’s hard to get a good PS/2 keyboard these days.

I have two simple questions.

  1. Is using female USB to male PS/2 adapter as good as using default PS/2 mouse and keyboard on Qubes?

  2. Any risk to using PCIe PS/2 card?

Note that PS/2 is pre-PCI: any PCI/PCIe “PS/2 card” is almost assuredly implemented using a PS/2 to USB circuit and a USB to PCI(e) bridge.
