Which USB version have I got?

Probably daft question of the day. Under Device Manager, I've got a dozen or so entries e.g. USB Printer Support etc..., but only one entry specifies a version (2.0), everything else just says 'USB'. Can I therefore assume I'm USB 2.0 compliant, and can connect devices which require this level of USB?

If your USB ports are all on the motherboard, I think you'll find they are all USB2. USB2 devices will work on USB1 ports - but at USB1 speed.

In Device Manager on my PC, I can tell if I have USB 2.0 as under 'Universal Serial Bus controllers' I have an entry for 'Standard Enhanced PCI to USB Host Controller'.


If you have this then you should be running USB 2.0 ;0)

I think it is the Root Hubs that you need to take note of. If this / these say 2.0, they are USB 2.0, if not they aren't (i.e. they are 1.1).

On my main system I have a combo of USB Root Hubs and USB 2.0 Root Hubs as I have 2.0 and 1.1 on the box.
