This product supports both USB 1.1 and 2.0 ports. We highly recommend to 
connect it DIRECTLY onto a Computer USB Port and not to a USB Hub. There are
so many different Hub makes and models, that it is impossible to test everyone
of them. Generally speaking, a non-powered Hub will not work but a Powered one
usually but not always should work. There are no guarantees on this.

NOTE:
    Please bear in mind that our published minimum requirements are based on 
    a test system that was reasonably optimized for performance (without a lot
    of overhead). A typical "casual home user" will often be unwilling to run 
    as 'lean' a system, so in-home performance may be compromised to some
    extent.
 
    We recommend using minimum requirements as a starting point, but faster 
    systems will provide better results. Other applications, especially games,
    may have higher system requirements. Refer to the applications documention
    for details.
