Hi Johan,
it’s good to hear that you already found out 🙂
Yes, there is currently a limit of seven USB-HID trackers on the same machine. The limit comes from a design choice to only use a single page of memory for the tracker metadata. We anticipate that the limitation will be removed sometime in the future but it’s hard to tell when that will be.
So I hope that a solution with, say, two computers, each hosting five trackers, can be viable for now.
