hi all, I'm using usb-cams since a long time. I'm shure, I had tested to use 2 cams at the same time several months ago - and they were working fine.
But now (kernel 2.4.9 and 2.4.14) on 2 different PCs with a different hardware, the following happens, if I try to access 2 cams at the same time: -------------------------------------------------- kernel: pwc Adding decompressor for model 740. kernel: pwc pwc_isoc_handler() called with status -84 [CRC/Timeout]. kernel: pwc pwc_isoc_handler() called with status -84 [CRC/Timeout]. kernel: hub.c: port 1 enable change, status 101 kernel: hub.c: already running port 1 disabled by hub (EMI?), re-enabling... kernel: hub.c: port 1, portstatus 101, change 2, 12 Mb/s kernel: usb.c: USB disconnect on device 2 kernel: pwc Disconnected while device/video is open! kernel: pwc pwc_isoc_handler() called with status -84 [CRC/Timeout]. last message repeated 3001 times --------------------------------------------------- the message: kernel: hub.c: already running port 1 disabled by hub (EMI?), re-enabling... always appears, if I access the second cam. One of the cams is locked then. (it hangs on ioctl-VIDIOSYNC) It does not matter, what kind of cam I use. (I've tried pwc and ov511) If I stop one of the reading-processes, the other cam then starts to work again. I am shure, it's n cable-problem..... Any hint or ideas ? best regards wicki :*) _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
