Summary: The ibmcam driver is not working
Product: Drivers
Version: 2.5
Kernel Version: 2.6.34
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: USB
AssignedTo: greg@xxxxxxxxx
ReportedBy: davidsen@xxxxxxx
Regression: Yes
This driver has been working, and around the 1st of May I updated my Fedora
kernel (FC13-RC) to current. The camera stopped working, so I built the latest
2.6.34-rc version and verified the problem. When 2.6.34 final released I
repeated the test and the driver is still not working.
Originally reported against Fedora (not going to be fixed in FC13) the
information in the Fedora report may be enough to identify the problem. I can
do a bit of test almost any day, but the cams are on a video monitoring system,
so I'm not able to do long bisects and such.
It's a 2.6.33 -> 2.6.34 regression, I think. I don't know whether it's
a v4l problem or a USB one..
It may very well be a regression, I don't know. But in general the usbvideo drivers
(of which the ibmcam is one) have been unmaintained for a long while, and they are
still v4l1 drivers. I've been slowly working on converting all old v4l1 usb webcam
drivers to the gspca usb webcam driver framework, removing a lot of code duplication
(and other cruft such as controls being controlled through module parameters)
from these drivers and making them v4l2 drivers in the progress.
I really bough 2 ibmcam driver using webcams in the US and had them shipped to the
Netherlands esp. for this purpose. I hope to have a new gspca subdriver to replace
ibmcam soon.
I know this is not really a fix for the problems with the existing ibmcam driver, but
as it is destined to be replaced soon anyways I think this is the best way forward.
Regards,
Hans
