This particular wording suggests it is *not* a high-speed 2.0 device,
but in fact only runs at USB 1.1 speed.  In either case it should be
backwards compatible with your USB 1.1 system, so no worries.

Note that "USB 2.0" is a meaningless term for the most part.  Unless it
also says "high-speed", there's no guarantee that it's not just USB 1.1
(at least performance wise).  When USB 2.0 came out several
manufacturers started applying the term to their laptops and other
devices even though they did not support the faster 2.0 features.

Beware of the fine print and confusing terminology.  "low speed" means
something like 2Mb/s, "full speed" means USB 1.1's 11Mb rate, and
"high-speed" means the very fast speed only available with 2.0.  But
just saying "2.0" in no way implies that the device supports this "high"
speed.

So remember: "high" is faster than "full" when it comes to USB speeds,
and "a full speed USB 2.0 device" is likely an attempt to confuse you
into thinking that something is better than it actually is.
