I have installed a plugable usb 3.0 i/o card on my Windows 7 computer. It shows up on my device manager, but when I plug in a 3.0 device it does not show up
Thanks for posting your question here, I’ll be happy to assist. I just have a couple of quick questions to help me get a better idea of your issue and then we’ll figure out the best next steps.
First, can you say if there is any warning on the device in device manager?
Next, make sure that you have the correct drivers installed, there are two different packages depending on which card you have. You can find details and links to download the drivers here:
Also check what happens when you plug in a simple USB device like a wired USB mouse. Does it work?
Let me know these additional details and we’ll figure out the best next steps to get you up and running.
