Here is what I can confirm:
Any decent quality mouse that I have seems to work just fine.
Mouses:
Logitech G203 - Works
MSI Gaming mouse - Works
Any Microsoft mouse I can find - They all work
Keyboards:
No name brand from AliExpress works (It is sold as an industrial keyboard and actually works in PS2 mode)
Strangely the Dell Keyboard I have doesn't, but Dell hardware is hit and miss. It either works perfectly for anything or is completely Windows locked.
The really cheap Woolworths mouse won't enumerate either but no love lost there.
The test isn't definitive. My USB2.0 breakout didn't arrive before the weekend, so I had to make my own, and it ain't pretty!
Even keyed it using a broken pin so that my drunk arse doesn't put the connector on backwards
