# # [31mCONFIG_USB[0m Core configuration # config [31mCONFIG_USB_ANNOUNCE_NEW_DEVICES[0m bool "USB announce new devices" help Say Y here if you want the [31mCONFIG_USB[0m core to always announce the idVendor, idProduct, Manufacturer, Product, and SerialNumber strings for every new [31mCONFIG_USB[0m device to the syslog. This option is usually used by distro vendors to help with debugging and to let users know what specific device was added to the machine in what location. If you do not want this kind of information sent to the system log, or have any doubts about this, say N here. comment "Miscellaneous USB options" config [31mCONFIG_USB_DEFAULT_PERSIST[0m bool "Enable USB persist by default" default y help Say N here if you don't want [31mCONFIG_USB[0m power session persistence enabled by default. If you say N it will make suspended [31mCONFIG_USB[0m devices that lose power get reenumerated as if they had been unplugged, causing any mounted filesystems to be lost. The persist feature can still be enabled for individual devices through the power/persist sysfs node. See Documentation/usb/persist.txt for more info. If you have any questions about this, say Y here, only say N if you know exactly what you are doing. config [31mCONFIG_USB_DYNAMIC_MINORS[0m bool "Dynamic USB minor allocation" help If you say Y here, the [31mCONFIG_USB[0m subsystem will use dynamic minor allocation for any device that uses the [31mCONFIG_USB[0m major number. This means that you can have more than 16 of a single type of device (like [31mCONFIG_USB[0m printers). If you are unsure about this, say N here. config [31mCONFIG_USB_OTG[0m bool "OTG support" depends on [31mCONFIG_PM[0m default n help The most notable feature of [31mCONFIG_USB[0m OTG is support for a "Dual-Role" device, which can act as either a device or a host. The initial role is decided by the type of plug inserted and can be changed later when two dual role devices talk to each other. Select this only if your board has Mini-AB/Micro-AB connector. config [31mCONFIG_USB_OTG_WHITELIST[0m bool "Rely on OTG and EH Targeted Peripherals List" depends on [31mCONFIG_USB[0m help If you say Y here, the "otg_whitelist.h" file will be used as a product whitelist, so [31mCONFIG_USB[0m peripherals not listed there will be rejected during enumeration. This behavior is required by the [31mCONFIG_USB[0m OTG and EH specification for all devices not on your product's "Targeted Peripherals List". "Embedded Hosts" are likewise allowed to support only a limited number of peripherals. config [31mCONFIG_USB_OTG_BLACKLIST_HUB[0m bool "Disable external hubs" depends on [31mCONFIG_USB_OTG[0m || [31mCONFIG_EXPERT[0m help If you say Y here, then Linux will refuse to enumerate external hubs. OTG hosts are allowed to reduce hardware and software costs by not supporting external hubs. So are "Embedded Hosts" that don't offer OTG support. config [31mCONFIG_USB_OTG_FSM[0m tristate "USB 2.0 OTG FSM implementation" depends on [31mCONFIG_USB[0m && [31mCONFIG_USB_OTG[0m select [31mCONFIG_USB_PHY[0m help Implements OTG Finite State Machine as specified in On-The-Go and Embedded Host Supplement to the [31mCONFIG_USB[0m Revision 2.0 Specification. config [31mCONFIG_USB_LEDS_TRIGGER_USBPORT[0m tristate "USB port LED trigger" depends on [31mCONFIG_USB[0m && [31mCONFIG_LEDS_TRIGGERS[0m help This driver allows LEDs to be controlled by [31mCONFIG_USB[0m events. Enabling this trigger allows specifying list of [31mCONFIG_USB[0m ports that should turn on LED when some [31mCONFIG_USB[0m device gets connected. |
