I am trying to plug a USB 2 device in a USB 3 slot. Nothing is being detected in "lsusb". Is there something special I need to do? I am running centos 5.5 x86_64. I thought 3.0 was backward compatible. Nothing special about my device its an RS232 to USB device. It works in 2.0 slot.
Thanks,
Jerry

It is backwards compatible, but the chipset might not yet be supported. What does lsdev show for the port?

I dont have lsdev - I do have lspci. Is this what you meant?

I don't have a lsdev either, I hope he meant lspci | grep usb* or something along those lines...:-)

Jerry, See the /var/log/messages and see if you see the device being detect by the kernel when you plug in. tail /var/log/messages should hint you something..

:D Working on AIX at the moment so got my ls*'s mixed..

So no driver installed.. There's a link I found: http://git.kernel.org/?p=linux/kernel/git/sarah/xhci.git;a=summary
But it appears you need a later kernel...

"Unknown device" from lspci does not in the general case imply a lack of driver. The only thing it says is that the pci-id database does not contain an entry for the component. The command "update-pciids" will update your pci-id database.
In this perticular case though, it seems that both 1) device not in pci-id db and 2) no driver loaded.

Very true. Thanks for clarifying.

Saw this link with some CentOS info: https://www.centos.org/modules/newbb/viewtopic.php?viewmode=thread&topic...
Following that eventually led to this: http://elrepo.org/tiki/kernel-ml
So it appears that you can load the mainline kernel and automagically get support for the device. I haven't located a module for the stock upstream vendor's kernel though.
I downloaded 2.6.34.8 - compiled and ran the new kernel making sure to enable XHCI and the device is now registered with lsusb.

That sounds great Jerry, the kernel upgrade worked for you. Just make sure you monitor that module since it is new and it might have glitches still. Keep that module up to date in your agenda.
