I am not promoting this as a fix all for every device. I since attached a POWERED 3.0 hub which I connected the Diamond BVU165 (USB 2.0) through the USB 3.0 hub and never had a problem since.

During this crash, the monitors would disconnect (turn black and go to sleep) and reconnect to the PC. Whenever I would watch movies or youtube videos on the PC, after 2-3 mins, the hub would crash and I could hear my scanner (also connected to the hub) reboot and go through the warm up procedure (USB powered only). I verified this later on because I have 2 additional monitors connected to my PC via a Diamond (BVU165) through a USB 2.0 powered hub. Sure enough, I plugged the unilink into the 3.0 port instead of the 2.0 port and never had a problem since. On a hunch I believed that the USB 2.0 port itself was the bottleneck.

I tried everything including contacting support, downloading the SetPoint app, switching ports (USB 2.0), etc. I had the unilink receiver plugged in to the 2.0 port and the keyboard would constantly lag to the point that I was going to return the solar keyboard to the store. So short answer yes, a small increase, but not nearly as fast as native USB 3.0 links. When I plugin a USB 3.0 thumb drive on the same ExpressCard USB 3.0 hub though, I get up to 122 MB/s. I think the controller is probably more efficient on USB 3.0. So I am getting both a higher minimum speed and ceiling when the same USB 2.0 device is on the USB 3.0 hub. If the enclosure is a USB 2.0 device, it will be operate with more of its bandwidth when plugged into a USB 3.0 hub, but not nearly as much as if it was a USB 3.0 to USB 3.0 device to hub link (with a USB 3.0 cable).Īt least on my laptop, USB 2.0 external 500 GB on USB 2.0 gives me about 19–23 MB/s and up to 25–32 MB/s when connected to a USB 3.0 express card. for instance a modern 7200 hard drive in a external enclosure could more than saturate the USB 2.0 port. You will only see gain if the device in question can dish out a higher bandwidth over another interface like ExpressCard or PCIe. Actually, yes, it will be faster by a small margin.
