Hi. I must be really unlucky: I have 2 webcams, tested on 3 differents freebsd (containing both UHCI & OHCI devices). The webcams are using pwc driver, from /usr/ports/multimedia/pwcbsd. I have applied the patch to use one of them with "motion"; but have every time the same error: "Too many ISOC errors, bailing out." pwcbsd is a version 1.4.1, it's seem old enought to be "stable", so I just can't figure out what's happening. Even pwcview don't work: it's just light-on the cam a fraction of seconds, clear the screen then give back the prompt. Here are the specs of what I have tested: home-made desktop freebsd 6.2-STABLE/amd64 recompiled kernel usb: ohci hp nc4000, FreeBSD 6.1-BETA4/i386 generic kernel Usb: ohci sony laptop (p800-quite-old) freebsd 7.0 Beta/i386 generic kernel usb: uhci (except for those 2 laptops, I can install & test any freebsd version and even give an ssh access on a fixed ip...) The webcams: Apr 11 20:53:37 nc4000 kernel: pwc0: vendor 0x046d product 0x08b2, rev 1.10/0.00, addr 2 Apr 11 20:53:37 nc4000 kernel: pwc0: Logitech QuickCam Pro 4000 USB webcam Apr 11 20:53:38 nc4000 kernel: pwc0: This camera is equipped with a Sony CCD sensor + TDA8787 (32) Apr 11 20:23:34 nc4000 kernel: pwc0: vendor 0x0471 product 0x0329, rev 1.10/0.03, addr 2 Apr 11 20:23:34 nc4000 kernel: pwc0: Philips SPC900NC USB webcam Apr 11 20:23:35 nc4000 kernel: pwc0: This camera is equipped with a Sony CCD sensor + TDA8787 (32) Apr 11 20:23:41 nc4000 kernel: pwc0: Too many ISOC errors, bailing out. (unfornutaly, I have bought the philips thinking the logitech was the problem, but it's seems the both are in fact the same thing with different plastics...) T.I.A. PM.
