An interesting approach is done here
http://www-user.tu-chemnitz.de/~heha/bastelecke/Rund%20um%20den%20PC/USB2LPT/index.html.en

This is a USB-parallel adapter which comes with a Windows device driver, 
that hooks into direct I/O accesses to the parallel port.
Thus a standard Wiggler ought to work when attached to this device, 
albeit a tad slowly when reading data.

I've not yet had time to test this.

When developing a "true" USB solution, the MPSSE embedded in the FTDI 
FT2232C should be an interesting starting point, given that there is 
software provided for JTAG access:

This I presume to be more interesting and time-worthy than mere bit-banging.
