bug in konicawc webcam driver

I have a problem with usb camera driver. It's konicawc. It was working in previous kernels 2.4 for sure (I have an old installation of Slackware 2.4.26) and perhaps in 2.6. Now in the latest kernel it doesn't work.
The file is /drivers/media/video/usbvideo/konicawc.c
I couldn't find anyone in MAINTAINERS for this driver and also
can't google how to fix this bug.

The error message is "Lost sync on frames" the same as here

There is a patch but it seems it's already applied in current source.

If it could help.I can try older version of 2.6 to find out when this driver broke.
