12d629c0e2SLukas Bulwahn	  This driver is for USB parallel port adapters that use the Lucent
13d629c0e2SLukas Bulwahn	  Technologies USS-720 chip. These cables are plugged into your USB
14d629c0e2SLukas Bulwahn	  port and provide USB compatibility to peripherals designed with
15d629c0e2SLukas Bulwahn	  parallel port interfaces.
16d629c0e2SLukas Bulwahn
17d629c0e2SLukas Bulwahn	  The chip has two modes: automatic mode and manual mode. In automatic
18d629c0e2SLukas Bulwahn	  mode, it looks to the computer like a standard USB printer. Only
19d629c0e2SLukas Bulwahn	  printers may be connected to the USS-720 in this mode. The generic
20d629c0e2SLukas Bulwahn	  USB printer driver ("USB Printer support", above) may be used in
21d629c0e2SLukas Bulwahn	  that mode, and you can say N here if you want to use the chip only
22d629c0e2SLukas Bulwahn	  in this mode.
23d629c0e2SLukas Bulwahn
24d629c0e2SLukas Bulwahn	  Manual mode is not limited to printers, any parallel port
25d629c0e2SLukas Bulwahn	  device should work. This driver utilizes manual mode.
26d629c0e2SLukas Bulwahn	  Note however that some operations are three orders of magnitude
27d629c0e2SLukas Bulwahn	  slower than on a PCI/ISA Parallel Port, so timing critical
28d629c0e2SLukas Bulwahn	  applications might not work.

3298bc06364SMatthias Kaehlcke	  This driver can be used as a module but its state (module vs
