Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I have a Ubuntu 12.04 system. On that system I have one USB 3.0 port. In this port I am trying use my USB 2.0 device, but every time when I plug in that USB 2.0 device into the USB 3.0 port, the system gets hung and I try to shutdown but it won't allow me to.

If I continue to match Port types to Device speeds (2.0 to 2.0) everything woks fine.

So my question is: How can I allow a USB 3.0 port to use a USB 2.0 device or is there any way to convert a USB 3.0 port to a USB 2.0 port like drivers or something?

Am I mistaking the issue I'm having for another type of problem?

Here is my lsub command output

Please add the relevant part of dmesg output to the question so it's not lost if the external stops working. –  Pavel Šimerda Apr 22 at 7:06

This sounds related to your issue: ubuntuforums.org/showthread.php?t=2090382. The only way to confirm would be to upgrade your kernel or distro though. –  slm Apr 26 at 16:04
