The mt9t031 works ok with the current kernel and system. However, udev does not create the /dev/video0 device node. I have to create it manually with mknod and then it works well. If I unbind the device on the soc-camera bus (and then eventually rebind it), udev then creates the node correctly. This looks like a "timing" issue at "coldstart". OpenEmbedded currently builds udev 141 and I am using kernel 2.6.33-rc5 (but this was already like that with earlier kernels). Is this problem something known or has at least someone already experienced that problem ?
