Dear fellow pd-ers,
I'm using comport to communicate with arduino/teensy for quite long time now, and I didn't encounter any serious issues while using one or two comport objects (and respectively one or two arduinos/teensies). But when I'm trying to connect three at a time, there are some problems, both when when connecting directly to computer's usb ports, and when using powered usb hub. I tried on two different computers. I'm getting this kind of messages in the console:
[comport]: WriteFile:GetOverlappedResult error: 31
[comport] ** ERROR ** couldn't reset params to DCB of device COM42
One of the teensies doesn't react, sometimes Pd freezes and unfreezes only when I disconnect the teensy in question.
Is there some hard limit in Pd - that you can't use more than two comports at once? Teensies are not draining that much power from usb, thei're controlling motor boards that have external power.
EDIT: I'm using latest available version of PD-Etended
