Driver for USB 3.0 PCIe Card  

Hello there, I'm a complete newby to formums so apologies in advance if I make a mistake.

I too have exactly the same problem with the 'Dynamode 4-port PCI-Express Card Superspeed USB3.0 plug n paly'. The drivers on the disc supplied did nothing, so I looked at the chip on the card ' VLI VL805-Q6' and did a search which lead me to the VIA website as mentionied in a previous post one this thread, were I downloaded the 2 driver files, VIA_XHCI_Driver_V4.50A_AP.exe & VIA_XHCI_Driver_V4.40D_AP.exe . The card was recognised after installing the V4.40D. exe program from the VIA website but was not running at 'superspeed' transfer rates of 5Gbps more like 50Mbps with a USB 3.0 HDD! However, when I logged off my PC for the night and logged on the next day the 2 HDD drives plugged into the PCI card were not showing, on checking device manager the yellow ! triangle appeared next to the VIA USB 3 root hub again. Anyone help further with this issue? My system is Win7 Home Premium 64bit.

I did notice on the download page there were extra files relating to the 05/06 chipset - I know its a pain downloading them from the site - don't recall now what exactly they were for, but they may help.
BTW - an hour for downloading - I WISH !! Took me nearly 36 hours to get 4.5 completed - kept timing out on me and failing.

I was having trouble with my startech usb 3.0 pci card. When connecting even a 2.0 thumb drive to the 3.0 port I'd get the message that it could go faster. The drivers on the cd that came with the card were from 2012. I d/l'd the VIA driver mentioned above 4.50 dated 2014. Installed it and now no notification of thumb drives able to go faster.

Though my galaxy S5 still created the alert when connecting to the computer. Found that the S5 defaults to usb 2.0 and you have to tell it to use usb 3.0. by swiping down on the phone screen when it is connected to the computer. A menu is listed with different connections. On mine the bottom one is usb 3.0. Select that and its done. While the phone is in usb 3.0 mode the phone goes into airplane mode. So no texts and such while usb 3.0 is in effect. Also once it has 5 minutes of inactivity the phone goes back to usb 2.0 speeds. Hope this helps.

That's a Via chip. Here is what I found.

It worked for me too.

Finally completed the download of the ZIP file from Taiwan. It unzips to VIA_XHCI_Driver_V4.50A_AP.exe.

And sure enough, that VEN_1106&DEV_3483 is present for XHCI:

Thank you very much for research and proof of correctness of this driver.

If somebody wants to find out, whether this driver is the correct one for him, he can check out this download link on gigabyte site:
GIGABYTE Motherboard GA-970A-DS3P (VIA USB 3.0 Driver)
It's quite outdated though.

It's ridiculously big (100MB) since it contains some weird "control tool" and .net redist, but downloads in minutes. It's a self-extracting archive you can open by 7-zip, and extract just the 14.6MB setup.exe.

17 hours later I decided to check out Ye Olde Windows 7 Forums and solved my problem within the hour.

I should have came here first instead of playing Mr.Independent to no avail. For those of us who have USB 3.0 HUBS and card readers running on Win 7 (because we stubbornly hold onto the last real o/s Microsoft ever made) this thread is Priceless. No more ugly yellow triangles in device manager! More importantly, usb 3.0 works front top and back! The wife will be impressed because she won't have to dual boot back to 8.1 to use all the hardware.

Hi, I decided to refresh the topic. I have a no-name card with the VIA VL805 chipset and the same problems: controller disappearing from CP, ports not working. I searched internet forums. There are different versions of the drivers - unfortunately only by VIA "for Evaluation Board reference only". Some suggest replacing the card firmware. There is also a possible problem with the power supply via the internal Molex connector. And here's my question - in not-working card are there voltages on the outputs or not?
