I operate the RK3288(Android5.1) board in dual-display(clone) mode. And one of them is the USB touch monitor.
When i touch the monitor, it often seems like a touch up event does not occur.
So, when I release my finger after touching it, it happens that it stays press.
I don't think it's a touch monitor problem because it works fine if I connect it to another board(RK3288 and not firefly).
Please advise if someone has encountered or solved the same problem as me.
