The Broadcom 7211 has new functionality that allows some USB low
speed side band signals, that go from the XHCI host controller to
pins on the chip, to be remapped to use any GPIO pin instead of the
limited set selectable by hardware. This can be done without changing
the standard driver for the host controller. There is currently
support for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. This
driver will allow the remapping of any of these three signals based
on settings in the Device Tree node for the driver. The driver was
written so that it could handle additional signals added in the
future by just adding the correct properties to the DT node.
Below is an example of a DT node that would remap all three
signals:
usb_pinmap: usb-pinmap@22000d0 {
compatible = "brcm,usb-pinmap";
reg = <0x22000d0 0x4>;
in-gpios = <&gpio 18 0>, <&gpio 19 0>;
brcm,in-functions = "VBUS", "PWRFLT";
brcm,in-masks = <0x8000 0x40000 0x10000 0x80000>;
out-gpios = <&gpio 20 0>;
brcm,out-functions = "PWRON";
brcm,out-masks = <0x20000 0x800000 0x400000 0x200000>;
interrupts = <0x0 0xb2 0x4>;
};

config USB_IDMOUSE tristate "Siemens ID USB Mouse Fingerprint sensor support" help Say Y here if you want to use the fingerprint sensor on the Siemens ID Mouse. There is also a Siemens ID Mouse Professional, which has not been tested with this driver, but uses the same sensor and may therefore work.
This driver creates an entry "/dev/idmouseX" or "/dev/usb/idmouseX",
which can be used by, e.g.,"cat /dev/idmouse0 > fingerprint.pnm".
See also <https://www.fs.tum.de/~echtler/idmouse/>.
config USB_FTDI_ELAN tristate "Elan PCMCIA CardBus Adapter USB Client" help ELAN's Uxxx series of adapters are USB to PCMCIA CardBus adapters. Currently only the U132 adapter is available.
The U132 is specifically designed for CardBus PC cards that contain
an OHCI host controller. Typical PC cards are the Orange Mobile 3G
Option GlobeTrotter Fusion card. The U132 adapter will *NOT* work
with PC cards that do not contain an OHCI controller. To use a U132
adapter you will need this "ftdi-elan" module as well as the "u132-hcd"
module which is a USB host controller driver that talks to the OHCI
controller within CardBus card that are inserted in the U132 adapter.
This driver has been tested with a CardBus OHCI USB adapter, and
worked with a USB PEN Drive inserted into the first USB port of
the PCCARD. A rather pointless thing to do, but useful for testing.
