Hi -questions! I'm having a strange problem with a USB Webcam under 4.6.2-RELEASE. The cam is a Puretek PT-6007, which is supported by the graphics/vid port. When connected into an old Compaq Deskpro, it works well, taking pictures almost without issue. Relevent parts of the Compaq's dmesg : uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x2020-0x203f irq 11 at de vice 20.2 on pci0 usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 usb0: USB revision 1.0 uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered ugen0: OmniVision OV511 Camera, rev 1.00/1.00, addr 2 However, when connected to an old no-name PC with a PCI USB adapter, it appears to be configured no problem : ohci0: <OPTi 82C861 (FireLink) USB controller> mem 0xef7ee000-0xef7eefff irq 10 at device 9.0 on pci0 usb0: OHCI version 1.0, legacy support usb0: <OPTi 82C861 (FireLink) USB controller> on ohci0 usb0: USB revision 1.0 uhub0: OPTi OHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered ugen0: OmniVision OV511 Camera, rev 1.00/1.00, addr 2 But when I try to use vid to take an image I get : ohci_device_isoc_start: not implemented on the console. Worse, the vid process hangs and if I try to kill it (but not before then) the whole machine hangs! I searched the archives and googled but I couldn't see anything relevent. I do note that the controller that the cam worked on was UHCI, but failed on an OHCI one. I've no idea if that's relevent though. After the system hangs, I can still use CTL-ALT-ESC and get the "No debugger in kernel" message, which I guess means if I compile in a debugger then I could get some diagnostics from the kernel if someone would like some. Any help or pointers would be appreciated! Thanks. Andrew. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
