2 bool "USB support"

4 Universal Serial Bus (USB) is a specification for a serial bus
5 subsystem which offers higher speeds and more features than the
6 traditional PC serial port. The bus supplies power to peripherals
7 and allows for hot swapping. Up to 127 USB peripherals can be
8 connected to a single USB host in a tree structure.
9
10 The USB host is the root of the tree, the peripherals are the
11 leaves and the inner nodes are special USB devices called hubs.
12 Most PCs now have USB host ports, used to connect peripherals
13 such as scanners, keyboards, mice, modems, cameras, disks,
14 flash memory, network links, and printers to the PC.

Paul Kocialkowski68f7c5d2015-08-04 17:04:05 +020016 Say Y here if your device has an USB port, either host, peripheral or
17 dual-role.

19 For an USB host port, you then need to say Y to at least one of the
Masahiro Yamada6e7e9292014-11-07 18:48:31 +090020 Host Controller Driver (HCD) options below. Choose a USB 1.1
21 controller, such as "UHCI HCD support" or "OHCI HCD support",
22 and "EHCI HCD (USB 2.0) support" except for older systems that
23 do not have USB 2.0 support. It doesn't normally hurt to select
24 them all if you are not certain.
25
26 If your system has a device-side USB port, used in the peripheral
27 side of the USB protocol, see the "USB Gadget" framework instead.
28
29 After choosing your HCD, then select drivers for the USB peripherals
30 you'll be using. You may want to check out the information provided
31 in <file:Documentation/usb/> and especially the links given in
32 <file:Documentation/usb/usb-help.txt>.

40 Enable driver model for USB. The USB interface is then implemented
41 by the USB uclass. Multiple USB controllers of different types
42 (XHCI, EHCI) can be attached and used. The 'usb' command works as
43 normal. OCHI is not supported at present.
44
45 Much of the code is shared but with this option enabled the USB
46 uclass takes care of device enumeration. USB devices can be

48 automatically probed when found on the bus.
