Ok for Xenial (v4.4) kernel, there's one missing commit that adds UVC1.5 to device ID.
The commit for this bug is still needed though. I'll send another SRU to backport the commit. ** Tags removed: verification-needed-artful verification-needed-xenial ** Tags added: verification-done-artful -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem in Ubuntu. https://bugs.launchpad.net/bugs/1763748 Title: Integrated Webcam Realtek Integrated_Webcam_HD (0bda:58f4) not working in DELL XPS 13 9370 with firmware 1.50 Status in Dell Sputnik: New Status in linux package in Ubuntu: Confirmed Status in linux-oem package in Ubuntu: Confirmed Status in linux source package in Xenial: Fix Committed Status in linux-oem source package in Xenial: In Progress Status in linux source package in Artful: Fix Committed Status in linux-oem source package in Artful: Invalid Status in linux source package in Bionic: Fix Committed Status in linux-oem source package in Bionic: In Progress Bug description: ===SRU Justification=== [Impact] UVC1.5 Realtek webcam on XPS 9370 does not work. [Test] Both the bug reporter and I can confirm the patch from Realtek works. [Fix] Use correct version control length for UVC1.5. [Regression Potential] Low. This only affects UVC1.5 webcams, which is quite rare in the wild. ===Original Bug Report=== The webcam is detected by the system, but no applications detect it. sudo lsusb -v: (relevant part) Bus 001 Device 002: ID 0bda:58f4 Realtek Semiconductor Corp.
