With a 2.4 kernel I can connect my usb camera and list/get pictures as many times as I would like. In 2.6 though I can do that only once, the 2nd and following times I get a timeout and the operation fails. I can use my camera again only after I power cycle it or reconnect it. Tried to re-emerge gphoto2 with /usr/src/linux symlinked and running 2.6 if that matters. Connecting the camera directly (not through a usb hub didn't help).
