Thread: libgphoto2-2 udev rule prevents webcam usage

in past few months, can no longer use creative pc cam 300 webcam (usb, 041e:400a). when plug in, no video device appears in /dev/ it.

poking around, i've discovered model of camera has entry in /lib/udev/rules.d/40-libgphoto2-2.rules seems load sort of photo downloading driver takes precedence on video functionality require. (this model of camera can, in theory, used portable stills camera low image quality, ever use webcam.)

when comment out relevant line in /lib/udev/rules.d/40-libgphoto2-2.rules, webcam works should do. when uncomment line, stops working again.

commenting out line in udev rules file in /lib/udev/rules.d/ not proper solution, liable overwritten during software updates.

can guide me towards proper solution problem?

not care if can no longer download photos camera. use webcam.

have tried copying libgphoto2-2.rules file new file /etc/udev/rules.d/45-libgphoto2-2.rules , commenting out relevant line. not solve problem.

have tried fudging rule

code:

subsystem=="video4linux", bus=="usb", attrs{idvendor}=="041e", attrs{idproduct}=="400a"

don't know enough udev , doesn't work.

apparently need libgphoto2-2 satisfy dependencies likes of wine , libsane, can't remove package.

can help.
