Hello, Please accept my apologies, if this is the wrong place to ask but it is so specialist I doubt I'll get much traction outside of this group. Logitech recently changed the C270 camera with a totally new board that behaves in subtle yet important ways - it is noticeable because the new board is blue whereas the old one is green. We've got some V4L code that uses ioctl DQBUF and QBUF to grab frames from the C270 unit, we have two units connected and they are both streaming at 1280x960 with an fps of 5. With the old, green, board this has been working for years. However on the new, blue, board we can only stream 1 camera in a process - if we try to stream two we have constant EAGAIN errno reported. Is this something seen before? It seems weird that the new revision of the logitech C270 causes the issue. Again, apologies if this is very specific and not of interest but I was hoping someone wiser than me would have some advice!
