I'm actually wondering if you're hitting a bug that is fixed by a patch
in my queue to send to Greg. Apparently, some BIOSes expect specific
USB ports on the mobile Panther Point chipset to remain under the EHCI
controller, even though they can be switched over to the xHCI host
controller.
Hi Sarah!
Thanks for your reply!
Can you run this git command, compile a kernel, and see if it fixes your
issue?
git clone git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git -b for-usb-linus
I did that but doesn't change anything. Same errors are still present.
This is from logs with this rebuilt kernel:
[ 293.314742] xhci_hcd 0000:00:14.0: Timeout while waiting for address
device command
[ 313.518513] xhci_hcd 0000:00:14.0: Timeout while waiting for address
device command

[ 314.778480] usb 3-3: device not accepting address 6, error -22

Please help. :)
