USB 3.0 hub showing as 2.1

loosenut said:

I don't think that's the issue - otherwise the USB flash drive would be running at 3.0. Does that make sense?

Well we are trying to isolate the problem you are having. It could be a mislabel product and its really is only a USB 2.0 device ? Looking at the HUB #'s, The HUB states is only running at USB 2.1 speeds on a USB 3.0 connection ? I question why it isn't showing a 3.0 speed ???

Just trying to help.

I appreciate your help! I'm attaching the two Tree View files, one with nothing connected to the Hub, and one with the USB 3 Flash Drive connected to the Hub. As I reminder, the USB 3 Flash Drive shows as USB 2 on all ports, of the Hub or when plugged in directly to the computer.

However, I just plugged the USB 3 drive into my laptop, and it does show as USB 3. When I plug the Hub into the laptop, it shows as USB 2.

So, that's all pretty weird.

Nothing jumps out at me from the logs.

You can try booting to a Ubuntu live USB drive and seeing if USB 3.0 is negotiated in Linux (by running lsusb -v). That way you can see if it's a Windows issue.

I believe the OP has a bogus USB 3.0 HUB. I decided to hook up a 3.0 hub on a 3.0 port and also plug in a USB 3.0 memory stick. I also have attached on a 3.0 port a USB 2.1 HUB and it has a couple USB 2.0 devices The following screen prints document the USB 2.0 HUB and its connection speed, followed by the USB 3.0 and its connection speed and finally the USB 3.0 Memory stick and its connected speed. I'm sorry but from what you have shown in this thread, it looks like its a 2.0 HUB.

Opps it looks like the attachments were inserted backwards from how described them above so the first one is the 3.0 USB stick.

I'm going to go with that. Time to contact returns. I appreciate everybody's help on this. Cheers!

Actually, before we close the thread, I'll post the results from plugging the device into Ubuntu on my laptop. The diff is pasted below. "bcdUSB 2.10" seems to indicate that it is USB 2.

Yes, that would indicate it's connected through USB 2.0.

That weird thing is that only USB 3 devices would use bcdUSB==2.10 (that version number was introduced in the USB 3 spec). So the hub is probably USB 3 but maybe there's a wiring issue.

I get that from time to time and to me the solution is usually to uninstall the entire USB device entries in device manager under "Universal Serial Bus Controllers" then reinstall Intel Chipset drivers (by manufacturer) and then reboot (Auto detect happens after bootup then) .

Usually that happens after plugging in pretty old devices where their installed drivers come to modify USB ones some how .
