I'm looking at this startech one on amazon which PB tech have listed as in stock with supplier for not too much more,

Anyone know of any other cards that have multiple controllers on one card? I am limited for slots on this computer and even with the onboard USB and a single controller card I am getting the dreaded insufficient USB controller resources message sometimes when connecting a few HDDs up to the computer.

The orientation of the plugs on the startech one sideways like they are worry me since I may have issues with plugs going in the gap in the case which many people have reported.

Power draw issue with the number of devices you are plugging in ? If so a powered hub would probably help.

No, they are all powered devices. Each hub is about 6 USB devices in one, and the drives have multiple devices. I always thought usb was supposed to go to 127 devices, but it seems there is a lower number of things called endpoints available on each controller, which HDD's use many of.

I've had the USB endpoint problem too, seems crazy they would impose such limits ... even worse if you have oculus rift as that uses a heap of USB ports too.

That startech card on amazon seems to be the best card for the money, am thinking about it myself.

A possible alternative is to buy usb2.0 backplates , connect them to the motherboard internal usb2.0 headers (most mobos seem to have these ) . Shift some slower devices from the usb3.0 ports to the usb2.0 ports (eg, mouse , keyboard etc).

That should free up some resources on the usb3.0 controller.... maybe enough if you are lucky.

Otherwise, get that startech card ( maybe consider usb3.1 c type controller , with adaptors)

USB 2 is on the same controller as 3 so even trying to use those headers won't help. Not like the old days where there was a separate controller for the 2 and 3 onboard.

Just noticed that the startech is a larger card so I may have to check what slots I have before trying to replace my aweful card with it. When I have the case out can check the size of the slots for the horizontal sockets.

Whatever you decide on, do a quick search to make sure it has drivers friendly to your OS. I've had a couple of USB3 cards that were a bugger to use with Windows 10.

Fixed the onboards with help from here and the USB 2 onboard ports are now useful again.
