I would like to use USB Input in a BrightScript Custom PlugIn.
I can handle GPIO, UDP, aso. but can not find any examples or documentation to USB.
What event type is it? What kind of data will be received (Str, int, float)
function USBin_ProcessEvent(event as Object)
'handle USB Inputs
if type(event)= "?????" then
eventData = event.Get?????()
endif
return false
end function
What type of USB device are you using?
Does it interface like a keyboard?
To get more insight, you could put a the top of the function this line:
print type(event)
You would then watch the terminal over serial port, or ssh, while interacting with the USB device.
Please share your experience here
It is a touch device from Phidget (linear touch) should be HID, unfortunately it doesn't send any event.
I get GPIO inputs, but neither Mouse or any other USB events.
Not all USB devices would generate USB events...
Getting GPIO events may be what you are looking for here.
Do those events correlate with touching the device?
See if you can get an integer value from the event...
Try to stop the script when a GPIO event is detected, and then explore it with the debugger.
Are you getting anything meaningful with event.GetInt() ?
Sorry, that was misleading by me. I get GPIO inputs from a GPIO button.
Just tested if the debug output worked at that point.
Do I need to register a special message port for USB inputs?
I don't think that you need to do anything special, but I may be wrong.
Not all USB devices are supported out of the box.
You can gain some insight, by examining the bottom of the log in the diagnostic web page, right after you plug in the USB cable.
At least it is recognized, No Errors

Recognized, doesn't necessarily mean supported.
The fact that you are not seeing any events, is not good news, but you should email that info to support@brightsign.biz, and they may be able to help.
