So, I have two USB 3.0 hubs and on two Windows 10 computers I have tested, I cannot get it to run a USB 3.0 speeds.
If I connect the testes device like flash drive directly to the USB 3.0 port on my computer then it runs around 125MB but the moment I plug into the hubs, they run around 35MB.
This is driving me crazy :/
Anyone has a hack, drivers, anything to help with this?
Under Windows 7 the same hubs run at full speed.

Thanks!
 
Now that I think about it I have the same issue but on Win8.

USB 3.0 can reach speeds as high as 625 MB/s. I am running HDTune on the USB 3.0 port right now and am getting just 32.9 MB/s max.

https://en.wikipedia.org/wiki/USB_3.0

Various early USB 3.0 implementations widely used the NEC/Renesas µD72020x family of host controllers,[37] which are known to require a firmware update to function properly with some devices.[38][39][40]

A factor affecting the speed of USB storage devices (more evident with USB 3.0 devices, but also noticeable with USB 2.0 ones) is that the USB Mass Storage Bulk-Only Transfer (BOT) protocol drivers are generally slower than the USB Attached SCSI protocol (UAS[P]) drivers.[41][42][43][44]

On some old (2009–2010) Ibex Peak-based motherboards, the built-in USB 3.0 chipsets are connected by default via a 2.5 GT/s PCI Express lane of the PCH, which back then did not provide full PCI Express 2.0 speed (5 GT/s), so it did not provide enough bandwidth even for a single USB 3.0 port. Early versions of such boards (e.g. the Gigabyte Technology P55A-UD4 or P55A-UD6) have a manual switch (in BIOS) that can connect the USB 3.0 chip to the processor (instead of the PCH), which did provide full-speed PCI Express 2.0 connectivity even back then, but this meant using fewer PCI Express 2.0 lanes for the graphics card. However, newer boards (e.g. Gigabyte P55A-UD7 or the Asus P7P55D-E Premium) used a channel bonding technique (in the case of those boards provided by a PLX PEX8608 or PEX8613 PCI Express switch) that combines two PCI Express 2.5 GT/s lanes into a single PCI Express 5 GT/s lane (among other features), thus obtaining the necessary bandwidth from the PCH.[45][46][47]

Read this url, seems it is a driver issue.

The hubs may be electrically dividing the bandwidth between ports. USB devices share bandwidth. But have you tried it on another computer to verify?
 
After reading that url I downloaded USBView and did some investigating. Turns out my bios options where set wrong and I am now getting 165MB/s. So check your bios settings for USB first.

So I was able to get one of the Hubs working (brand VEMONT and no model part). It only works on my Laptop though. On my main PC (both running windows 10 64its) still wont run at full speed.
One thing I notice is that on Device Manager my laptop shows it as Generic SuperSpeed Generic USB Hub. On my main PC it only shows as Generic USB hub. I have tried uninstalling and letting it reinstall but no luck.
I am about to just get a long USB 3.0 cable and forget about the hub! :/
I did have a USB 2.0 hub also on my main pc so I removed it and still wont show that SuperSpeed hub device.

I see but my problem is that the USB port works fine at 3.0 as long as I plug the device directly to it, is when I use the HUB that it drops to USB 2 speeds and now only on my main PC. My Laptop works fine and it is also running 10 64bit.

And I use that program from the link and indeed mine is Renesas USB 3.0 root HUB ad the device is showing as USB 2.0. Wont connect as 3.0 for some reason.
I saw someone said it was a driver issues but I am yet to find a fix.

I just ordered two extension cables from Amazon. Not going to break my head with this lol

Even though HDTune shows USB3.0 speeds now in practice you get no where near those speeds when transferring files. I just transferred 7.42GB to a USB 3.0 device and saw as low as a few MB/s and briefly as high as 45 MB/s.

You could try to manually change the driver to the SuperSpeed Generic one.
 
I've had similar issues with Renesas USB 3.0 chipsets before, although the issue I had was that the whole USB hub would simply vanish out of device manager and therefore stop working altogether.

It's been an issue since Windows 8, was never an issue under Windows 7.
