This is a note to let you know that I've just added the patch titled

usb: quirks: add quirk to start video capture on ELMO L-12F document

to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release during the merge window.

If you have any questions about this process, please let me know.

Without this quirk starting a video capture from the device often fails with

kernel: uvcvideo: Failed to set UVC probe control : -110 (exp. 34).
