If you are driving the pixels fast with fast changes and the transmit light on the USB is on constantly, then there is too much data for the USB. If you are running at the default 57600 baud rate, increase the baud rate to 250000. That will increase the communications speed to the controllers.
To change the baud rate, use the device manager and change the baud rate on all your controllers, then change the speed of you USB-485 network in the Show Designer.
Increasing the speed should solve your issue, but if it doesn't you may have to change your show so the pixel changes are slower, or control pixels in pairs rather than individually.
Pixels require a lot of data. This is one of the issues with Pixels and relatively slow serial communications. If using a lot of pixels then the Ethernet controller is best, as Ethernet is much faster.
Let us know how you get on.
