This option adds core support for Universal Serial Bus ([31mCONFIG_USB[0m).
You will also need drivers from the following menu to make use of it.

Universal Serial Bus ([31mCONFIG_USB[0m) 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 [31mCONFIG_USB[0m peripherals can be
connected to a single [31mCONFIG_USB[0m host in a tree structure.
The [31mCONFIG_USB[0m host is the root of the tree, the peripherals are the
leaves and the inner nodes are special [31mCONFIG_USB[0m devices called hubs.
Most PCs now have [31mCONFIG_USB[0m 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 [31mCONFIG_USB[0m port and you want
to use [31mCONFIG_USB[0m devices. You then need to say Y to at least one of the
Host Controller Driver (HCD) options below. Choose a [31mCONFIG_USB[0m 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 [31mCONFIG_USB[0m 2.0 support. It doesn't normally hurt to select
them all if you are not certain.
If your system has a device-side [31mCONFIG_USB[0m port, used in the peripheral
side of the [31mCONFIG_USB[0m protocol, see the "USB Gadget" framework instead.
After choosing your HCD, then select drivers for the [31mCONFIG_USB[0m 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>.
To compile this driver as a module, choose [31mCONFIG_M[0m here: the
module will be called usbcore.
config [31mCONFIG_USB_PCI[0m
bool "PCI based USB host interface"
depends on [31mCONFIG_PCI[0m
default y
---help---
Many embedded system SOCs (e.g. freescale T2080) have both
[31mCONFIG_PCI[0m and [31mCONFIG_USB[0m modules with the [31mCONFIG_USB[0m module directly controlled by
registers and having no relationship to the [31mCONFIG_PCI[0m module.
If you have such a device you may say N here and [31mCONFIG_PCI[0m related code
will not be built in the [31mCONFIG_USB[0m driver.

---help---
This driver is for [31mCONFIG_USB[0m parallel port adapters that use the Lucent
Technologies USS-720 chip. These cables are plugged into your [31mCONFIG_USB[0m
port and provide [31mCONFIG_USB[0m 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 [31mCONFIG_USB[0m printer. Only
printers may be connected to the USS-720 in this mode. The generic
[31mCONFIG_USB[0m 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 [31mCONFIG_PCI[0m/[31mCONFIG_ISA[0m Parallel Port, so timing critical
applications might not work.
Say Y here if you own an USS-720 [31mCONFIG_USB[0m->Parport cable and intend to
connect anything other than a printer to it.
To compile this driver as a module, choose [31mCONFIG_M[0m here: the
module will be called uss720.
