Actually, an active cable won't work, either, I'm sorry to say. The problem is
that that 4.5 meter limit only applies to high-speed devices; low-speed devices
are limited to three meters. With an active cable, I'd get intermittent mouse
support under FreeBSD, and my Mac OS X system would actually panic after a
while.
There is a solution: Chain some powered hubs with some 3m cables. For a
25-foot span, you could probably get away with two hubs:
Computer]----3m cable----[HUB]----3m cable----[HUB]----[mouse

10' 10' 5'
This solution works very well for me---no more system panics, and rock-solid
mouse support.
Best of luck.
