Directly connect 5 touch panels to a PC, all 5 touch panels can be operated at the same time without problem.

If connect to the VE8900, when 4 touch panels are connected, the 4 touch panels can be used normally (1T 4R). When the 5th touch panel is connected, the 5th touch panel will not work at all.

If replace the touch panels with 5 USB mice. As a result, the 5 USB mice can be used normally.

Touch Screen and USB mouse are supported differently, Touch Screen is supported by bypass mode.

The USB bypass mechanism can only support 4 devices at the same time, this is the limitation on VE transmitter.
