So I went through all the System Devices and Universal Serial Bus Controllers in the list and updated all of them that mentioned Intel, chipset or USB, directing it to use the INF/driver files from the downloaded Intel® Chipset Device Software version 9. The readme had instructions for doing it manually through device manager but it did not correspond to the names of my devices. When I tried to run setup.exe it said "This computer does not meet the minimum requirements for updating the software". The one that gave me an error was listed as INF, Intel® Chipset Device Software version 9. So I thought I will try installing them again.

I complained to Microsoft support about the USB problem and they suggested I install drivers from the motherboard manufacturer. A couple of them did not install and gave me error messages - I assumed they were not compatible with my machine.

I did attempt to install all the relevant Windows 8 64 bit drivers from my motherboard manufacturer's website. Here is where I got mine - ASRock > B75 Pro3-M )Īfter upgrading from Windows 7 to Windows 8 (64 bit) my USB 3.0 ports would only operate as USB 2 ports - at slow speed and Windows would say "device can perform faster if connected to USB 3" I had to get the inf/driver files from my motherboard manufacturer's website (Check your motherboard manufacturer's site. If you have an intel brand motherboard I believe you can just use this - Download Center (Try running the setup.exe first, it might work for you)

At first I had trouble installing it, but using device manager you can manually update the Intel chipset and USB drivers one by one and point it to the folder with the downloaded inf/driver files. Intel® Chipset Device Software version 9. It has fixed my problem, I hope it may work for other people too.
Our solution was attaching the server with 5 PCI 4x USB Cards which allowed us to stack 110 devices per server.I found a solution that does not require unsigned drivers. However even with active power supply on the hubs and good cable connections we had issues if we added more than 1 7er Hubs (=7 devices) per physical mainboard USB Port. On our setup we were limited to 3 additional hubs per Port. So you should check which port on your hub is connected to the "primary" and "secondary" hub.Īdditionally you cannot put more than 5 hubs in row, (including root hub + possible already another hub on your mainboard before you even reach the USB Plug) Most of the time you get 7 Port hubs there are actually 2 Hubs inside the case row. Measure the power output of the USB cables. Make sure you do not use too long cables between host and hubs, low cost ones did produce high amount of issues for us on even 3m length, while USB2.0 specs allow for 5m Cable until you need a "Hub" Technically my answer is USB2.0 info i give but it might help you get some ideas where to look at.

I'm hoping that there is a way around this limitation with the Intel hardware - another driver or a different controller altogether.įirst: i do not know if there might be a bug/feature limit on your USB host controller or spec limitation (in case of devices, hubs in row) change in USB2 vs USB3 (Davids Answer seems to show the limit of the intel controller) We are sure that this is a power issue but all of the hubs are powered and the cameras are also on mains adapters.Īt the moment we are having to fall back to USB2 but the transfer rate means that the photo capture process has increased significantly - each image file is around 23MB and it can take 20 seconds or so to download all of the files. The system has three of these - all powered, but will only support around 11 of the connected devices (two and a bit hubs worth). The configuration is that the cameras connect to a powered USB3 hub ( something like this) which allows 7 devices to be attached. I am working on a project which utilises 18 high-end DSLR cameras, connected to a PC via USB.ĭuring development the system was running USB2 will no problems whatsover but when we moved to a system running USB3.0 we started getting the following error which resulted in only 11 of the cameras being recognised.
