Subject: Chronic USB disconnect events for Pinnacle Dazzle DVC 100 video capture device
Date: Thu, 25 Feb 2010 13:52:52 -0500 [thread overview]
Message-ID: <4B86C704.3060709@swartzlander.org> (raw)
I have a Pinnacle Dazzle DVC 100 USB video capture device hooked up to a
security camera capturing video 24/7. A few times a month, my kernel
suddenly decides that the USB device was disconnected and reconnected,
resulting in the device getting a new number and causing my recording
software to stop recording until I restart it with the new device
number. Here is an example of the dmesg output when it happens:
[1126917.418424] usb 2-8: USB disconnect, address 3

This machine is running Ubuntu 8.10 with kernel 2.6.27-17-generic. Is
this a known problem for this particular capture device or a potential
driver issue? Should I be bugging the USB people instead of this list?
Any ideas would be appreciated.
thanks,
