Hi
Try to go on cypress.com.They have SL811HS USB host controller.which is interfaced in parallel.All the details are available online
 

Most of the time you want something fast. This meas you dont have to spend too much time learning.

FTDI provides some circuits that allows to simplifi the USB interface to a simple serial o parralle port. So you convert the USB problem to an already known serial o parrallel interface.

Just take a look at it.
