AR1100 fails to connect while using the configuration software

The problem may be one of the following:

  • The controller is not changing from HID-generic back to HID-mouse/HID-digitizer. If you can connect to the AR Configuration Utility, try to 'Restore Defaults' and start over.
  • Windows® treats the three modes (HID-mouse, HID-digitizer, HID-generic) as three separate devices and installs them separately. If USB enumeration failed on one mode, it may never recover in that mode yet still work with other modes. To fix this, you must reinstall the driver under that mode (get Windows to recognize the device again). To do this, connect the AR board and if it is not working, go to Device Manager and find the device; it may be under 'Other Devices' and listed as 'Unknown'. Then, right-click and uninstall the device. After that, reconnect the AR and let it search for the driver again.
  • USB attachment must occur within a certain time on the AR1100 board or it will revert to RS232 mode.
