USB 1.1 is more likely.  But yes, point valid beyond the nitpick.

$ echo '(15*1024*1024)/(5*60*60)' | bc

873 bytes per sec?  That's crap.  This an old computer?  How many USB
ports?  No hubs, right?

I typ get 6MB/sec writing and 15 MB/sec reading on USB2.0.  If it's
USB1.1, I typ just give up.  USB 1.1 is for keyboards and mice.  Lack
of USB2 is a good indicator that the computer in question is too crap
to bother with.  Computers of that age a subject to break down and use
too much power.  But if you are sure you want to keep using it and it
has pccard/cardbus (i.e. old laptop but not too insanely old) I do
have a USB2 pccard card I'd be happy to donate- it's doing me no good.
