HIDRAW
The hidraw backend supports maXTouch devices which connect using USB or HID over I2C.
The hidraw interface is documented in the Linux kernel source, in Documentation/hid/hidraw.txt.
The device must have /dev/hidraw raw HID device support enabled using the CONFIG_HIDRAW kernel configuration option.
To use hidraw, provide a DEVICESTRING such as d. There is no scanning support. Bootloading is not supported in this mode.
It is possible to use the –flash command with a device already in bootloader mode by specifying the bootloader address only for USB-HID mode.
