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

and memory deallocation are deferred on close.

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,
-Ben Swartzlander
