|
Universal Serial Bus (USB) is a specification for a serial bus |
|
subsystem which offers higher speeds and more features than the |
|
traditional PC serial port. The bus supplies power to peripherals |
|
and allows for hot swapping. Up to 127 USB peripherals can be |
|
connected to a single USB host in a tree structure. |
|
|
|
The USB host is the root of the tree, the peripherals are the |
|
leaves and the inner nodes are special USB devices called hubs. |
|
Most PCs now have USB host ports, used to connect peripherals |
|
such as scanners, keyboards, mice, modems, cameras, disks, |
|
flash memory, network links, and printers to the PC. |
|
|
|
Say Y here if your computer has a host-side USB port and you want |
|
to use USB devices. You then need to say Y to at least one of the |
|
Host Controller Driver (HCD) options below. Choose a USB 1.1 |
|
controller, such as "UHCI HCD support" or "OHCI HCD support", |
|
and "EHCI HCD (USB 2.0) support" except for older systems that |
|
do not have USB 2.0 support. It doesn't normally hurt to select |
|
them all if you are not certain. |
|
|
|
If your system has a device-side USB port, used in the peripheral |
|
side of the USB protocol, see the "USB Gadget" framework instead. |
|
|
|
After choosing your HCD, then select drivers for the USB peripherals |
|
you'll be using. You may want to check out the information provided |
|
in <file:Documentation/usb/> and especially the links given in |
|
<file:Documentation/usb/usb-help.rst>. |

|
Many embedded system SOCs (e.g. freescale T2080) have both |
|
PCI and USB modules with the USB module directly controlled by |
|
registers and having no relationship to the PCI module. |
|
|
|
If you have such a device you may say N here and PCI related code |
|
will not be built in the USB driver. |

|
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. |
