It differs from hiddev in that reports sent and +received are not parsed by the HID parser, but are sent to and received from +the device unmodified. + +Hidraw should be used if the userspace application knows exactly how to +communicate with the hardware device, and is able to construct the HID +reports manually. This is often the case when making userspace drivers for +custom HID devices. + +Hidraw is also useful for communicating with non-conformant HID devices +which send and receive data in a way that is inconsistent with their report +descriptors. Because hiddev parses reports which are sent and received +through it, checking them against the device's report descriptor, such +communication with these non-conformant devices is impossible using hiddev. +Hidraw is the only alternative, short of writing a custom kernel driver, for +these non-conformant devices. + +A benefit of hidraw is that its use by userspace applications is independent +of the underlying hardware type. Currently, Hidraw is implemented for USB +and Bluetooth. In the future, as new hardware bus types are developed which +use the HID specification, hidraw will be expanded to add support for these +new bus types. + +Hidraw uses a dynamic major number, meaning that udev should be relied on to +create hidraw device nodes. Udev will typically create the device nodes +directly under /dev (eg: /dev/hidraw0). As this location is distribution- +and udev rule-dependent, applications should use libudev to locate hidraw +devices attached to the system. There is a tutorial on libudev with a +working example at: + http://www.signal11.us/oss/udev/ + +The HIDRAW API +--------------- + +read() +------- +read() will read a queued report received from the HID device. On USB +devices, the reports read using read() are the reports sent from the device +on the INTERRUPT IN endpoint. By default, read() will block until there is +a report available to be read. read() can be made non-blocking, by passing +the O_NONBLOCK flag to open(), or by setting the O_NONBLOCK flag using +fcntl(). + +On a device which uses numbered reports, the first byte of the returned data +will be the report number; the report data follows, beginning in the second +byte. For devices which do not use numbered reports, the report data +will begin at the first byte. + +write() +-------- +The write() function will write a report to the device. For USB devices, if +the device has an INTERRUPT OUT endpoint, the report will be sent on that +endpoint. If it does not, the report will be sent over the control endpoint, +using a SET_REPORT transfer. + +The first byte of the buffer passed to write() should be set to the report +number. If the device does not use numbered reports, the first byte should +be set to 0. The report data itself should begin at the second byte. + +ioctl() +-------- +Hidraw supports the following ioctls: + +HIDIOCGRDESCSIZE: Get Report Descriptor Size +This ioctl will get the size of the device's report descriptor. + +HIDIOCGRDESC: Get Report Descriptor +This ioctl returns the device's report descriptor using a +hidraw_report_descriptor struct. Make sure to set the size field of the +hidraw_report_descriptor struct to the size returned from HIDIOCGRDESCSIZE. + +HIDIOCGRAWINFO: Get Raw Info +This ioctl will return a hidraw_devinfo struct containing the bus type, the +vendor ID (VID), and product ID (PID) of the device. The bus type can be one +of: + BUS_USB + BUS_HIL + BUS_BLUETOOTH + BUS_VIRTUAL +which are defined in linux/input.h. + +HIDIOCGRAWNAME(len): Get Raw Name +This ioctl returns a string containing the vendor and product strings of +the device. The returned string is Unicode, UTF-8 encoded. + +HIDIOCGRAWPHYS(len): Get Physical Address +This ioctl returns a string representing the physical address of the device. +For USB devices, the string contains the physical path to the device (the +USB controller, hubs, ports, etc). For Bluetooth devices, the string +contains the hardware (MAC) address of the device. + +HIDIOCSFEATURE(len): Send a Feature Report +This ioctl will send a feature report to the device. Per the HID +specification, feature reports are always sent using the control endpoint. +Set the first byte of the supplied buffer to the report number. For devices +which do not use numbered reports, set the first byte to 0. The report data +begins in the second byte. Make sure to set len accordingly, to one more +than the length of the report (to account for the report number). + +HIDIOCGFEATURE(len): Get a Feature Report +This ioctl will request a feature report from the device using the control +endpoint. The first byte of the supplied buffer should be set to the report +number of the requested report. For devices which do not use numbered +reports, set the first byte to 0. The report will be returned starting at +the first byte of the buffer (ie: the report number is not returned). + +Example +--------- +In samples/, find hid-example.c, which shows examples of read(), write(), +and all the ioctls for hidraw. The code may be used by anyone for any +purpose, and can serve as a starting point for developing applications using +hidraw. + +Document by: + Alan Ott <alan@signal11.us>, Signal 11 Software diff --git a/drivers/hid/Kconfig b/drivers/hid/Kconfig index 9de9e97149ec..67d2a7585934 100644 --- a/drivers/hid/Kconfig +++ b/drivers/hid/Kconfig @@ -55,12 +55,6 @@ source "drivers/hid/usbhid/Kconfig" menu "Special HID drivers" depends on HID -config HID_3M_PCT - tristate "3M PCT touchscreen" - depends on USB_HID - ---help--- - Support for 3M PCT touch screens. - config HID_A4TECH tristate "A4 tech mice" if EXPERT depends on USB_HID @@ -100,12 +94,6 @@ config HID_BELKIN ---help--- Support for Belkin Flip KVM and Wireless keyboard. -config HID_CANDO - tristate "Cando dual touch panel" - depends on USB_HID - ---help--- - Support for Cando dual touch panel. - config HID_CHERRY tristate "Cherry Cymotion keyboard" if EXPERT depends on USB_HID @@ -300,12 +288,6 @@ config HID_MICROSOFT ---help--- Support for Microsoft devices that are not fully compliant with HID standard. -config HID_MOSART - tristate "MosArt dual-touch panels" - depends on USB_HID - ---help--- - Support for MosArt dual-touch panels. - config HID_MONTEREY tristate "Monterey Genius KB29E keyboard" if EXPERT depends on USB_HID @@ -320,13 +302,25 @@ config HID_MULTITOUCH Generic support for HID multitouch panels.
