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-testing 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 be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 1ebe718bb48278105816ba03a0408ecc2d6cf47f Mon Sep 17 00:00:00 2001 From: Stefan Ursella <stefan.ursella@xxxxxxxxxxxxxx> Date: Wed, 10 Feb 2021 15:07:11 +0100 Subject: usb: quirks: add quirk to start video capture on ELMO L-12F document camera reliable Without this quirk starting a video capture from the device often fails with kernel: uvcvideo: Failed to set UVC probe control : -110 (exp. 34).
