USB Interface
Many maXTouch devices support a USB mode which reports touches via USB-HID. In addition, evaluation boards may use a “bridge chip” which converts the I2C to USB protocol. USB support in mxt-app is enabled during compile time of the source.
With a maXTouch USB device attached mxt-app will find the first available unit. To specify a particular USB device, a DEVICESTRING option is required. The corresponding bus and device number can be given using the -q/--query option or kernel app lusb. The following options are available for USB:
EXAMPLE: Find specific USB device on bus #1 and device #3
./mxt-app -d: usb:001-003
