I've been having repeated BSOD's, this is the first one I've gotten a debuglog out of. I'll post more when it happens again.

The BSODs happen only when I'm away from the computer. I guess that means it has to be idle for a while for this to happen. I'm running Kerio Personal Firewall 4, and I'm almost certain that this was the cause. Just wanting to double check, though.

Minidump attached, since it seems to be too long to post.

is it a mobile or desktop computer?
the debug log tells something about a usb device that failed. do you use any removable storage devices? maybe the power settings interrupt the connection between usb device and computer?
its difficult and just guessing from the little background you gave us. maybe you can tell more about the computer and other devices you connect/use with the computer.
on first sight it doesn't really look like a firewall problem here....

Well, the computer has a few USB memory sticks in it, but they stay connected throughout. Keyboard, mouse, webcam are connected through USB as well, but I don't see how those could cause a BSOD.

I'm saying it was probably a firewall issue because Kerio is known to throw BSOD's left and right, and my memory passes Memtest86 and I can't think of anything else that could be defective.

well I was just guessing because the debug.log says this:

and that indicates a usb device error. I also wonder how many usb device you use at once. I mean it can work since not all of them are powered over usb but it is many device from what I think!

not sure about the firewall program since I donno it, sorry.

Hmm, it says 'usbhub' in there a few times, my monitor has a few USB slots and acts as a hub. I'll try disconnecting the USB drives when I leave the PC, but I don't think that'll be the end of it...

well, every usb controller is kind of a usb hub. the question is how many device can it handle or better how many of them can be powered by usb. you see keyboard and mouse get the power from ubs and so do usb flash drives and maybe you cam unless it has a power supply.
