My 5 years old Dell Dimension 4100 has two USB ports. How can I find out,
whether they are USB1 or USB2 ?

given the age of the machine they are almost certainly USB v 1.0 or 1.1

Some Googling says this is the motherboard:

ICH2 UHCI USB driver = USB 1.1

If it supported USB2, it would have said EHCI. In which case
there would be an entry in the USB section of Device Manager
that has the word "Enhanced" in it.

If there is a spare PCI slot, you might add a USB2 PCI card.
USB2 cards that have a "NEC" chip are good.

And, if you are going to add a card, consider adding one that supports both
Firewire and USB2. SIIG makes card that supports Firewire 400, Firewire
800, and USB2.

Are the SIIG cards as fast at USB2 though?
One can get among the fastest possible USB2-only cards with
an NEC chipset for about $15, delivered (varies $5 per
promos/sales/etc).

The SIIG card runs USB2 as the same rate that other USB2 cards run, but also
adds both variants of Firewire. If you want to save a few dollars, combo
USB2/Firewire 400 cards (without Firewire 800) are less expensive. The SIIG
card has several ports, at least one each for USB2, Firewire 400, and
Firewire 800. You can use just one port, or all of them at the same time.

Sure it runs it at "same rate" but that doesn't necessarily
mean the actual throughput is the same. Point being,
having a card that does these several features is good, but
if it doesn't do the needed feature as well and costs
more...
