Increasing USB Host Controller Capacity?
Not a Max question, per se. But I am hopefully someone on this board might be able to help.
I recently made some adjustments to my workstation and added a bunch of new toys. I'm running into some problems now where when I plug in a USB device I get an error saying (paraphrasing) "Too many USB devices, unavailable port"
I am aware that the USB Host controller on the motherboard has a fixed capacity for USB ports, something like 127 ports. And that many devices consume more than one port, and that layering multiple hubs can consume a lot of ports.
Due to the nature of my layout, I don't think there's much more I can do to optimize the topography of my USB tree.
Does anyone know if there is a device out there can provide increased USB Host Controller capacity? If so, which one?
I see the PCIe USB boards that have 4 or 7 ports on them. But I don't know if they actually provide Host Controller Capacity, or if they just add even more ports to my motherboard's already overwhelmed USB host.
Thanks for any input!
PCIe usb card could be best solution, in case you are not using that many usb devices that system can't assign as many IO addresses, which I doubt.
but maybe you are connecting devices in a wrong way.
it is impossibe to say more without knowing all details, about host,
connected usb internal and external devices.
intel xhci usb contrllers are known to have limits
