CONFIG_USB_USS720: USS720 parport driver

General informations

The Linux kernel configuration item CONFIG_USB_USS720 has multiple definitions:

USS720 parport driver found in drivers/usb/misc/Kconfig

The configuration item CONFIG_USB_USS720:

Help text

This driver is for USB parallel port adapters that use the Lucent Technologies USS-720 chip. These cables are plugged into your USB port and provide USB compatibility to peripherals designed with parallel port interfaces.

The chip has two modes: automatic mode and manual mode. In automatic mode, it looks to the computer like a standard USB printer. Only printers may be connected to the USS-720 in this mode. The generic USB printer driver ("USB Printer support", above) may be used in that mode, and you can say N here if you want to use the chip only in this mode.

Manual mode is not limited to printers, any parallel port device should work. This driver utilizes manual mode. Note however that some operations are three orders of magnitude slower than on a PCI/ISA Parallel Port, so timing critical applications might not work.

Say Y here if you own an USS-720 USB->Parport cable and intend to connect anything other than a printer to it.

To compile this driver as a module, choose M here: the module will be called uss720.
