Public bug reported:
(This bug report supersedes bug #427327)
On my MSI Wind with bison webcam (5986:0203) most of the time I boot
karmic (2.6.31-10.35 kernel) I get these error in dmesg:
[ 18.861916] ehci_hcd 0000:00:1d.7: force halt; handhake f8046424 00004000
00000000 -> -110
[ 18.877866] hub 1-0:1.0: cannot reset port 6 (err = -108)
[ 18.877882] hub 1-0:1.0: cannot reset port 6 (err = -108)
[ 18.877893] hub 1-0:1.0: cannot reset port 6 (err = -108)
[ 18.877904] hub 1-0:1.0: cannot reset port 6 (err = -108)
[ 18.877913] hub 1-0:1.0: cannot reset port 6 (err = -108)
[ 18.877921] hub 1-0:1.0: Cannot enable port 6. Maybe the USB cable is bad?
As a consequence the system will fail to suspend and recognize USB mass
storage devices, which is a main problem.
Further investigation shows it only happens when the uvcvideo module is
loaded.
System works well if uvcvideo is not loaded, either by disabling the
webcam before rebooting (FN+F6) or by blacklisting the uvcvideo module
in /etc/modconf.d/.
If I blacklist uvcvideo and load it manually after boot (modprobe) the
same thing happens: most of the time I get "cannot reset port" error and
USB storage and suspend is non-functional from then on.
In very rare occasions (1 in 10 or less) the system loads uvcvideo and
does not give "cannot reset port" errors and all suspend, USB storage
and webcam are functional.
This is a regression since it does not happen with ubuntu 9.04: I have
used 9.04 for months before and it also works well if I boot with 9.04
-netbook-remix usb image.
Considering that the MSI Wind and its several clones are quite popular
and that this bug will make suspend and USB unfunctional, it may have a
quite big impact on ubuntu users, specially the netbook-remix friends.
