Hm. It seems there's a more serious problem either with your USB hardware or drivers. I'm way off my depth here, but throwing the error message into a search engine (no, I don't "google" things ;-) yields [1] [2], which recommend: (1) trying another USB cable/hub (2) reformatting the memory device (DON'T DO THAT WITH YOUR CAMERA, i'd say) (3) booting with kernel option 'irqpoll' (4) setting the old_scheme_first parameter in the usbcore driver, either by "echo Y | sudo tee /sys/module/usbcore/parameters/old_scheme_first" or by booting with kernel option 'usbcore.old-scheme-first=1' (5) booting with kernel option 'acpi=off' Since things seem to have gone south after upgrade, (1) doesn't seem very plausible. OTOH it's usually a very cheap option to try, so if you have some cables lying around, I'd try that first. Options (3) and (4) seem to be worth a try; I haven't much confidence in (5) and I'd rule out (2) -- who knows whether the camera has important tidbits in the storage it exports as USB.
