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>. 	  To compile this driver as a module, choose M here: the	  module will be called usbcore. config USB_PCI	bool "PCI based USB host interface"	depends on PCI	default y	help	  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. config USB_PCI_AMD	bool "AMD PCI USB host support"	depends on USB_PCI && HAS_IOPORT	default X86 || MACH_LOONGSON64 || PPC_PASEMI	help	  Enable workarounds for USB implementation quirks in SB600/SB700/SB800	  and later south bridge implementations. These are common on x86 PCs	  with AMD CPUs but rarely used elsewhere, with the exception of a few	  powerpc and mips desktop machines. if USB source "drivers/usb/core/Kconfig" source "drivers/usb/mon/Kconfig" source "drivers/usb/host/Kconfig" source "drivers/usb/renesas_usbhs/Kconfig" source "drivers/usb/class/Kconfig" source "drivers/usb/storage/Kconfig" source "drivers/usb/image/Kconfig" source "drivers/usb/usbip/Kconfig" endif comment "USB dual-mode controller drivers" source "drivers/usb/cdns3/Kconfig" source "drivers/usb/fotg210/Kconfig" source "drivers/usb/mtu3/Kconfig" source "drivers/usb/musb/Kconfig" source "drivers/usb/dwc3/Kconfig" source "drivers/usb/dwc2/Kconfig" source "drivers/usb/chipidea/Kconfig" source "drivers/usb/isp1760/Kconfig" comment "USB port drivers" if USB source "drivers/usb/serial/Kconfig" source "drivers/usb/misc/Kconfig" source "drivers/usb/atm/Kconfig" endif # USB source "drivers/usb/phy/Kconfig" source "drivers/usb/gadget/Kconfig" source "drivers/usb/typec/Kconfig" source "drivers/usb/roles/Kconfig" endif # USB_SUPPORT
