Title: UVC Quanta 0408:4035 camera PROBLEM Status in linux package in Ubuntu: New Bug description: I bought a Acer Nitro 5 AN517-55 with Quanta ACER HD User Facing', USB 0408:4035. The camera is reported to have problems by many users: https://linux-hardware.org/?id=usb:0408-4035 The uvc camera Quanta 0408:4035 does not work with ubuntu 22,04. the camera is “recongized” but fails installation. My console commands report similar info to other users: https://unix.stackexchange.com/questions/723504/integrated-camera-not-detected-working-on-acer-nitro-5-an515-58 PROPOSED SOLUTION I got in contact with laurent.pinch...@ideasonboard.com and with riba...@chromium.org , and subscribed to https://www.linuxtv.org/lists. And me...@vger.kernel.org mailinglist. Laurent proposed me a fix and I modified the 5,15 uvc_driver.c version, and loaded it on github https://github.com/Giuliano69/uvc_driver-for-Quanta-HD-User- Facing-0x0408-0x4035-/blob/main/uvc_driver.c I offered to test the fix, so I tried to compile the module with the new source. COMPILING PROBLEMS I’m running **Ubuntu 22.04.1 LTS, with kernel giuliano@Astra2A:/usr/src$ cat /proc/version_signature Ubuntu 5.15.0-56.62-generic 5.15.64 BUT the linux-source that I found installed seems to be different tgiuliano@Astra2A:/usr/src$ ls -al linux-so* lrwxrwxrwx 1 root root 47 nov 22 16:08 linux-source-5.15.0.tar.bz2 -> linux-source-5.15.0/linux-source-5.15.0.tar.bz2 I expanded the tar file, configured the IDE and compiled without error any errors… I manually copied the uvcvideo.ko in /lib/modules/5.15.0-56- sudo cp…... then tryed to intall the new uvcvideo.ko module sudo rmmod uvcvideo && sudo modprobe uvcvideo BUT… IT FAILS giuliano@Astra2A:~$ sudo rmmod uvcvideo && sudo modprobe uvcvideo modprobe: ERROR: could not insert 'uvcvideo': Exec format error and dmesg shows [25961.151982] usbcore: registered new interface driver uvcvideo [26323.125534] usbcore: deregistering interface driver uvcvideo [26323.189294] uvcvideo: disagrees about version of symbol module_layout These are the TWO modinfo from the old and new uvcvideo modules https://pastebin.com/tSj8Exm6 Basically OLD module: vermagic: 5.15.0-56-generic SMP mod_unload modversions NEW module: vermagic: 5.15.64 SMP mod_unload modversions -kindly ASK HOW can FORCE the uvcdriver.c to match mi kernel version ? Have I got OTHER ways to make the kernel module I’m compiling, match my running system ? I would like to test the module so to confirm the patch and let it enter the kernel main stream... BR Giuliano PS btw…. to allow Eclipse to compile the kernel, I had to pass this commands scripts/config --disable CONFIG_SYSTEM_REVOCATION_KEYS scripts/config --disable SYSTEM_REVOCATION_KEYS scripts/config --disable SYSTEM_TRUSTED_KEYS hope that this does not affect the module layout & checking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2000947/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
