feet from the pc, first of

Dan,

according to the poor man's wi site
" we had 5 x 5m cheap USB 2.0 M-F extenders cobbled together for a 25m
( 75') run, for which the USB adaptor never missed a beat. "
I would think that what you were powering - say for example a hard
drive which would require more power the distance factor would be more
of an issue.
The USB hubs seem to come in two varities - powered and non powered.
The non powered ones are the less inexpensive ones .
The powered hubs to make a power boost to the line are the preferred
variety.

Maximum distance is 5m.
You're within spec - just buy a 5m (or 15' if you're unlucky enough to live
in the states) cable.

16ft is the official limit. I've gone 42ft without any noticeable
problems. It seems to vary with the quality of cables. I have a
thin, cheezy, 6ft USB extension on my desktop that barely works. The
wire guage for the 5VDC power is apparently (my guess) so thin, that
the USB device is running undervoltage and craps out. I bought some
really stiff and heavy cables, and find that I can go to 42ft with
them. It also depends on the wireless device. My assorted 802.11b
devices will work on longer cables than 802.11g devices, which run USB
2.0 instead of 1.1 and at higher data rates on the cable.

The safest bet (other than the usual trial and error) is to get an
active USB cable or use a USB hub, as others have suggested. Seach
Google for "active USB cable".

For really long distances, there are some expensive devices:

Some of which run on CAT5.
