** Description changed: Hi all, Problem: The LED on this webcam is always turned on when connected to USB, unless some application uses it - the behavior that is opposite to what is expected. It was tested on Ubuntu 9.10 32 bit, kernel 2.6.31-19-generic. lsusb shows the webcam information as follows: ID 093a:2460 Pixart Imaging, Inc. Q-TEC WEBCAM 100 Suggested solution: The driver for this camera is gspca_pac207 (located at /lib/modules/2.6.31-19-generic/kernel/drivers/media/video/gspca). In the driver source file pac207.c it can be seen that the bit 1 of the register at 0x41 controls the LED. Looks like it was assumed that '0' at this bit turns the light off, when actually '1' does that. After I've changed the value of this register to the opposite, the re-compiled driver works correctly and the LED is on only when the camera is in use. I've attached the modified pac207.c. The diff of the changed file vs. original is below: 272c272 < pac207_write_reg(gspca_dev, 0x41, 0x02); --- > pac207_write_reg(gspca_dev, 0x41, 0x00); 308c308 < mode = 0x00; /* Image Format (Bit 0), LED (1), Compr. test mode (2) */ --- > mode = 0x02; /* Image Format (Bit 0), LED (1), Compr. test mode (2) */ 331c331 < pac207_write_reg(gspca_dev, 0x41, 0x02); /* Turn off LED */ --- > pac207_write_reg(gspca_dev, 0x41, 0x00); /* Turn of LED */ + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + ApportVersion: 1.23-0ubuntu4 + Architecture: i386 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: yuri 1733 F.... pulseaudio + /dev/snd/controlC0: yuri 1733 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'PCH'/'HDA Intel PCH at 0xfaa00000 irq 52' + Mixer name : 'Intel CougarPoint HDMI' + Components : 'HDA:10ec0892,1043841b,00100302 HDA:80862805,80862805,00100000' + Controls : 39 + Simple ctrls : 21 + Card1.Amixer.info: + Card hw:1 'NVidia'/'HDA NVidia at 0xfa080000 irq 17' + Mixer name : 'Nvidia GPU 15 HDMI/DP' + Components : 'HDA:10de0015,10de0101,00100100' + Controls : 16 + Simple ctrls : 4 + DistroRelease: Ubuntu 11.10 + HibernationDevice: RESUME=UUID=de1eeb67-9373-4213-9118-ae26c42861ed + InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release i386 (20110427.1) + IwConfig: + lo no wireless extensions. + + eth2 no wireless extensions. + MachineType: System manufacturer System Product Name + NonfreeKernelModules: nvidia + Package: linux (not installed) + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-26-generic-pae root=UUID=8e0e5216-29f9-432a-9298-ec75abcd3f07 ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.0.0-26.43-generic-pae 3.0.43 + RelatedPackageVersions: + linux-restricted-modules-3.0.0-26-generic-pae N/A + linux-backports-modules-3.0.0-26-generic-pae N/A + linux-firmware 1.60.1 + RfKill: + + StagingDrivers: mei + Tags: oneiric running-unity staging + Uname: Linux 3.0.0-26-generic-pae i686 + UpgradeStatus: Upgraded to oneiric on 2011-10-30 (353 days ago) + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare + dmi.bios.date: 04/01/2011 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 1002 + dmi.board.asset.tag: To be filled by O.E.M. + dmi.board.name: P8H67-M PRO + dmi.board.vendor: ASUSTeK Computer INC. + dmi.board.version: Rev 1.xx + dmi.chassis.asset.tag: Asset-1234567890 + dmi.chassis.type: 3 + dmi.chassis.vendor: Chassis Manufacture + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1002:bd04/01/2011:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP8H67-MPRO:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: + dmi.product.name: System Product Name + dmi.product.version: System Version + dmi.sys.vendor: System manufacturer ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/525959/+attachment/3402820/+files/AcpiTables.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/525959 Title: 093a:2460 Webcam (Pixart PAC207BCA) - inverted LED logic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/525959/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
