The limits on USB are the same for 1.1 as 2.0 afaik

No more than 5 metres of unboosted cable.  (I have a mouse with a 6 foot
cord on the end of a 5 metre extension and it works on a USB2 port but not a
USB1 port)

Maximum total length is 25 metres with active signal boosters every 5
metres.   (probably to do with bit times and all that coax ethernet timing
stuff from last century.)

I expect that you could make a USB cable as long as you like, but the 
signals have a high clock rate so they would degrade past a certain point 
(that and the voltage drop). 5m might be an arbitrary limit set by the USB 
specification, but it is not unreasonable, and guaranteed to work.
