Hi
I have a fuji finepix e550 which is "recognised" by the uvc driver. When I plug in the camera I see this messages in dmesg: usb 2-1: new full speed USB device using uhci_hcd and address 5 usb 2-1: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device USB Web Camera (04cb:0172) and a device node is created: /dev/video0 (and a symlink /dev/video to it) unfortunately it does work. It fails with the following error message: Message from [EMAIL PROTECTED] at Wed Jan 17 01:20:25 2007 ... dellD800 kernel: Oops: 0000 [#4] Message from [EMAIL PROTECTED] at Wed Jan 17 01:20:25 2007
