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
