The library uses libusb to access USB devices and the - ppdev interface to communicate + ppdev interface to communicate with parallel cables. The parallel part currently only supports Parallel Cable III mode (and PCIV in PCIII compatibility mode) as the faster PCIV modes use another kernel module which is not emulated by this library. So you are limited to a 200kHz JTAG clock when using Parallel Cable IV with this software. The USB cable is supported at full speed.

+The library is called libusb-driver as it was developed to support the USB cable, but later extended to also support parallel cables.
