Canon EOS 50D dslr connected to usb ports attaches but detaches after few seconds, between 1 and 4 seconds. ugen6.2: <Canon Inc.> at usbus6 ugen6.2: <Canon Inc.> at usbus6 (disconnected) usbconfig list does not show any Canon device any more. How-To-Repeat: attach canon eos 50D firmware version 1.07 with usb on freebsd 8.0 laptop.
Can you try with an 9-current kernel? --HPS
I will try this later this week. Maybe tomorrow time allowing. Regards Robert Blacquiere

Hi, Maybe your device needs a UMASS quirk to be able to function. In FreeBSD-8+, see /usr/src/sys/dev/usb/storage/umass.c and /usr/src/sys/dev/usb/quirk/usb_quirk.c . --HPS
I experience the same problem with Canon EOS 450D and 8.2-STABLE from around this May. Any further pointers (except trying 9.0-CURRENT, which is not an option for me right now)? A bit more information: apparently, this happens when camera is plugged in, but not being accessed for some time, so it will disconnect after several seconds. Plugging it in and using gphoto2 to query information or start transferring images works reliably, it does not disconnect in the middle of the process. Unfortunately, I cannot recall what was the behavior on 7.X.
