EVERY USB hub I EVER bought has this SAME issue!!! I've tried everything from the cheap hubs to the $50 hubs, powered hubs & unpowered hubs, they ALL have this SAME issue within a couple of hours of plugging them in!!! they ALL say "A device attached to the system has malfunctioned and Windows doesn't recognize it" and/or frequently connecting and disconnecting itself (hardware insert/remove sound) it's NOT my USB ports because they work just fine without a hub but ALL hubs I plug in to my laptop has this problem, and it DOESN'T MATTER what USB port or what brand of hub I use either, ALL SAME ISSUE!!!!

Does it happen only on one particular computer? How many and what devices are simultaneously connected when this happens?

I've only tried them on one computer and I have all 4 USB ports full and about 4 in the hub

So that makes about 8 devices on laptop. The problem seems not being able to handle the amount of power draw from the usb hub which shares from one usb port. If you lower the number of devices connected on the usb hub, does it reproduce the same message? Have you tried using the AC powered usb hub instead?

cheap hubs to the $50 hubs, powered hubs & unpowered hubs

 

Is it not more likely to be a bandwidth issue ?  Effectively all four ports on the hub are passing data through one USB port on the computer at the same time. I don't know enough about the detail of the USB standards to be certain about what happens if you try to overload the computer port, but at the least performance is going to suffer. It is equally possible that the system tries to dump load by switching some of the units off.

Or it could be that a USB device that does not like hubs (so to speak) is plugged into the hub. Some USB devices just HAVE to be plugged directly into a USB port on the computer.

Usually, it is a power issue that requires the direct connection, but not always.
