I'm having an issue with my usb 3.0 port. I've recently bought an Asus
N73JF laptop which has one such port. I'm running a fully updated
Squeeze with the 2.6.32-5-amd64 kernel image from the Debian repo.
During boot I see lots of:
"hub 1-1:1.0: unable to enumerate USB device on port 5" and the port
doesn't work.
What kind of device do you have attached to the USB 3.0 port? What
happens if you attach another device?
When I run "lspci -v" I get the following (among others):
(...)
So obviously xhci is used for it, as it should I guess. Some google
search returned, that it might be an issue with ehci getting in the way
so I experimented a bit with modprobe. I disabled ehci_hcd and when I
typed "modprobe xhci_hcd" I got the following response:
FATAL: Module xhci_hcd not found.
Hum, I would try the opposite: enforce the use of "ehci_hcd" (or
uchi_hcd, whatever you have it in your system) and see how it goes
(unload "xhci_hcd" and connect the USB 3.0 device to the USB 3.0 port,
then run "dmesg" to get the output messages).
It's the same with ehci enabled so I guess this has nothing to do with
it. I looked into /sys/bus/pci/drivers/ and xhci_hcd is there all right.
Does anyone know what I'm missing? It would be nice to be able to use
the usb 3.0 but I can't seem to find any solution. All advice are
welcome
I guess that USB 3.0 stack is still under heavy development in the latest
kernel branch (2.6.37.x) :-?
