USB Interface

Many maXTouch devices support a native USB interface which reports touches via USB-HID. Evaluation touch boards also use a “bridge chip” which converts the I2C to USB protocol. USB support in mxt-app is enabled during compile time in the source.

With a USB device attached mxt-app will find the first available controller. 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
