Dear Kai-Heng thank you vefry much for your contribution. I do have a webcam version 15.0 I (think I) installed your .deb and rebooted and this is what I see in the journal: apr 16 15:18:39 ox kernel: Linux video capture interface: v2.00 apr 16 15:18:39 ox kernel: usbcore: registered new interface driver btusb apr 16 15:18:39 ox kernel: uvcvideo: Found UVC 1.50 device Integrated_Webcam_HD (0bda:58f4) apr 16 15:18:39 ox kernel: uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.

Two questions: a) how can I make sure I am running your version (the uname -r is the same...) b) is there any other output you would like to see?
P.S. needless to say the webcam is not working ATM :-) Thanks Stefano 2018-04-17 9:04 GMT+02:00 Kai-Heng Feng <kai.heng.f...@canonical.com>: > Please try this kernel, > https://people.canonical.com/~khfeng/lp1763748/ > > I made an ugly workaround to keep the UVC version at 1.0.
