I'm going to have 3 controllers total, and was planning to use usb serial interface, is there a way to query a serial number or something? I know I could query the device type, but that's not enough. I have 1 HDC2450 and 2 HDC2450S's, so I could identify the HDC2450, but not between the hdc2450s's. I should be able to figure out which USB is connected, but i'd like to be extra sure, and I was just hoping there was a serial number or something to query. I can't find anything like that in the documentation.

The usb/serial interface doesn't seem to have a serial number either.

Since I can identify the HDC2450 dual channel, if I just put the 2 HDC2450S's on different USB bus's that would be easy to figure out pro grammatically, but i'd rather have a solution that wouldn't matter if I re-do all the USB connection order, for whatever reason, and that would query and determine which USB channel was which.

Thanks,

Controllers dont have a unique id but you can use the "controller address" parameter to store any 16-bit value you want.

YOu will need to do this separately for each controller initially using the console and the following command:

^cad nn (nn is the address value)
%eesav (to permanently save the value in eeprom)

Then after you have all controller hooked up on the usb, query that number with the ~cad command.

Perfect, thank you.
