USB 3 host port out of resource
I have a system using a variable number of Cypress FX2 devices to control data acquisition. The host system can be either windows 7 or 8. Each FX2 has three open pipes when in use. When I connect to a USB 2.0 host port I can connect a large number of units in various combinations of hubs and devices without any problem.
When I connect to a USB3 host port I get an "out of resource" message from the win 8 system or a "code 10 error" with win 7 when I connect in excess of 13 units (29 pipes) in any combination of hubs and units. All hubs and units are self powered.
Any help with this would be appreciated.
