Hello,
I tried to calibrate my Adafruit AR1100 5" and 7" 800x480 TFT HDMI Backpack with AR configuration utilities. Whatever configuration I chose, it gave an error as like in the attached snapshot. The error message is like "could not change the mode to HID, verify the AR1100 is properly attached"
I use it as the secondary display. It shows the desktop. But when I touched it, the touchscreen did not respond but my primary display respond instead.
Please help me solve the problems. Thanks.

you may have to run the AR1100 program a bit, but it ought to find it eventually! we use it here to test the board :)

How do I run it? I tried all the possible configurations like 4 wire, 9 pin something.

Here is the screenshot of my device manager. Now I can use the touchscreen and it displays well. But I still cannot calibrate it with AR configuration untilities. The error message always shows up: Could not change mode to HID. Verify the AR1100 is properly attached.

what OS version are you using? is there any emulation or virtualization going on?
