Dear tinggg,

Hmm.. very good question.. I would say if you know your system specifications of your machine unless specifically stated
it has USB 2.0 , it should have USB 1.1 and also if your machine is more than 1 yr old it should have USB 1.1 ..

This is an immediate check .. But wait for other experts answer on this ..

There would be nothing in Device Manager regarding the version but looking at the USB driver there should be  a way of telling .

Thanks,
Sunray

why don't you plug in some known USB 2.0 devices  eg card reader, RAM drives etc and if you don't get a message such as " you have connectted a USB 2.0 high speed device to a low speed port etc" you have a USB 2.0 port. Other method is to check your manual (how often people will read it or keep it) to find out 1/ if you have USB 2.0 controller or 2/ which chipset your m/b use eg SIS 961/962 etc.
