|
|
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 device has an USB port, either host, peripheral or
|
|
dual-role.
|
|
|
|
For an USB host port, 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.txt>.

|

Enable driver model for USB. The USB interface is then implemented
|
|
by the USB uclass. Multiple USB controllers of different types
|
|
(XHCI, EHCI) can be attached and used. The 'usb' command works as
|
|
normal. OCHI is not supported at present.
|
|
|
|
Much of the code is shared but with this option enabled the USB
|
|
uclass takes care of device enumeration. USB devices can be
|
|
declared with the U_BOOT_USB_DEVICE() macro and will be
|
|
automatically probed when found on the bus.
