Have no idea if that's workable as I have no idea what your objective are.Thanks for the reply
I was thinking about the daemond/service running on PC that will check com port's value in regular periods.According to the value I will trigger an action.
Is that workable?
@GetDeviceInfo:Can you explain a little more "
A toggle on the USB port will generate a useful interrupt"
Not at all familiar with the PCs' USB host controllers, but with all the micros / dedicated host controllers I've worked with, pulling D+ or D- low will generate an interrupt, indicating attachment. I'm making an assumption, but I can't see any reason you couldn't hook into this event.
