Hi Theodore It looks like I'll have to keep checking eBay for cheap USB v3 (HD) webcams periodically. Which somebody will need to support because they will probably not work out of the box with an OEM driver CD ;-) Ah yes, there is that aspect to think about before making a purchase :-).

Hi Theodore As to getting that kind of resolution out of a webcam, though, it would be a rather tough go due to the amount of data which has to pass over the wire even if it is compressed data. The frame rate would be pretty atrocious. Therefore, you are probably not going to see that kind

Hi Jean-Francois It seems that the webcams handled by the driver sn9c20x work the same as the ones handled by sonixj. In this last driver, I adjust the JPEG compression to avoid the errors USB FIFO full, and I think that these errors also raise the URB error -18 with the sn9c20x. I will need

Hi Hans The good news is that the nasty errors I was getting yesterday have magically disappeared overnight! That is likely because the scene you're pointing at (or the lighting conditions) have changed, not all pictures compress equally well with JPEG. If you point the camera at the same

Hi Hans Thanks for letting me know that this problem will be fixed in Linux v3.3. It could be several weeks before my distribution releases that kernel. Dropping back to Linux v3.1 isn't an option, as my NVIDIA driver requires Linux v3.2. Can the fix for this problem also be applied to Linux
