Could you post the output of `usbdevs -v' when the camera is plugged
in? The "BBB reset failed" error message is exactly what I saw
before C1 support was added to umass.c, so I suspect your camera
has a different product ID, but needs the same workaround.

For a quick solution, try editing umass.c, and find the lines:

	if (UGETW(dd->idVendor) == USB_VENDOR_OLYMPUS &&
	    UGETW(dd->idProduct) == USB_PRODUCT_OLYMPUS_C1) {
		/*
		 * The Olympus C-1 camera uses a different command-status
		 * signature.
		 */
		sc->quirks |= WRONG_CSWSIG;
	}

Then change the condition so that all Olympus cameras can use the
workaround:

	if (UGETW(dd->idVendor) == USB_VENDOR_OLYMPUS) {
		/*
		 * The Olympus C-1 camera uses a different command-status
		 * signature.
		 */
		sc->quirks |= WRONG_CSWSIG;
	}

If that fixes the errors, the `usbdevs -v' output will be enough
to get the driver updated to work properly with this camera in
future.
