How to plugin USB PCIe card to C2S2 slot
Hi all,
I need to plug in all USB PCIe cards to all PCIe slots in Dell T7910.
All USB cards were plugged into PCIe slot in CPU1 work fine.
Just two USB cards were plugged into PCIe slot in CPU2 cannot recognize. Please note that I tried to move VGA card to PCIe slot in CPU2 and it worked fine, except USB card did not work.
Could you please give me some suggestions?
Thanks,
Hoang

You cannot plug in cards into slots with reckless abandon. You cannot plug card after card after card whether nic, usb card, video etc. Each card uses a specific amount of bandwidth which is why you cant plug multiple USB cards into the bus or 6 video cards etc. This is also why chipsets have a limited number of USB2 and USB 3 ports because of Bus Bandwidth. If you need more usb ports you should use an Active Hub not multiple cards. There isn't any vendor that says you can use as many slots as you want and plug USB cards into them. This is not supported and never will be.
