Windows 7: USB 3.0 Ports Not Working with USB 3.0 Devices

Uninstalling the root hubs would be a starting place, but that'll disable your mouse or keyboard if you have them USB connected.

USB 3.0 cables are much bigger than USB2.0 ones. They are about as big in diameter as an ethernet cable and have 9 conductors as opposed to USB 2.0's four.

Please post a picture of these devices and see the thread below.

I had an issue with my USB 3.0 ports and "Other Devices" that is how I found this great forum and the link below was my very first post.

USB 3.0 Ports Not Working

Not sure how helpful the picture will be but here it is!



Also, I'm confident that at least one of my blue USB cables is a true 3.0 cable. It is very thick and has a "square" connector at one end that is taller than normal -- has sort of an "attic" to it.

I'll have a look at that thread.

Also, I'll try the uninstall -- I have a PS2 keyboard I can use. I can turn on mouse keys if I get stuck.

You might try running Unknown Device Identifier:

Unknown Device Identifier - Freeware Download

It not only helps ID devices, but can also find drivers for them if needed.

Solved: I'm a bit embarrassed but I have a defense. First, my defense <g>. I've been around for a while and even though I may not be current on my tech, driver installation habits die hard. I make it a point to point devices at drivers via device manager rather than point a driver install or setup at my system. In the past this ensured I didn't get extra stuff and was rarely a problem.

In this case I pointed all device candidates at the USB driver package and came up with the three hubs but no roots. Not surprisingly, the three unknown devices were my three roots but I couldn't point them at anything -- driver update wasn't an option.

So, the solution was to run the driver setup and get out of the way. Let me know if I owe anybody beer money for time spent

Thank you sincerely.

Glad you got it running. Enjoy USB 3.0!

I have a similar problem. My Western Digital My Passport isn't able to connect through my USB 3.0 port, but works fine on any USB 2.0. Other USB 2.0 drives work on that USB 3.0 port too, so I'm not sure what the issue is. Attached are screenshots for the different scenarios.

I checked your motherboard specs you have listed for your system and the Biostar TA785G3 does not appear to have USB 3.0 ports only USB 2.0. Is this the correct motherboard or do you have an add-on card and if so what make and model?

▲This - the specs for that board are x4 USB 2.0 ports - no mention of USB 3.0

If it's the correct board and you have an add on card, have you installed the drivers for it?
