GPIB is not realy slow by todays standars. It's still capable of
transfering more data pr sec than USB 1, there is some notes about it at
NI.
The Prologix box consist of an an microcontroller and an USB chip or such,
but the programming involved in order to get it all working is extencive if
you want to support some of the early instruents.

I use the Prologix USB box often. It appears as an serial port, and is easy
to use. As fair as I understand, the GPIB-LAN device you just telnet into.
