| bdmurray | uvcvideo is blocking my laptop from suspending | 01:48 |
| bdmurray | I receive an error message when that kernel module is loaded and I try to suspend with 2.6.22-11. | 01:51 |
| === osmosis [n=steven@cpe-76-80-127-252.socal.res.rr.com] has joined #ubuntu-kernel | ||
| bdmurray | Actually, I don't understand why that module is being loaded on my system. | 02:22 |
| bdmurray | Whay does this "alias: usb:v*p*d*dc*dsc*dp*ic0Eisc01ip00*" alias match? | 02:23 |
| bdmurray | s/Whay/What/ | 02:23 |
| kylem | any device that claims to be usb video, subclass video control | 02:30 |
| bdmurray | kylem: So uvcvideo will loaded for any unknown webcam? | 02:32 |
| kylem | it's a match based on the capability of the usb device, not it's specific vendor/device ids. | 02:32 |
| mjg59 | bdmurray: If it claims to be a USB video device, which most webcams don't | 02:34 |
| bdmurray | okay, but I don't understand why the module would be loaded for devices that are supported by the driver | 02:34 |
| bdmurray | maybe webcam was the wrong word, the camera in my laptop then | 02:34 |
| kylem | lsusb -v | egrep 'bInterface.*Class' | 02:34 |
| mjg59 | Your camera presumably claims to implement the USB video class | 02:35 |
| bdmurray | Okay, so it might work with uvcvideo then? | 02:37 |
| mjg59 | bdmurray: It claims that it should do. It might be lying, or uvcvideo might be broken. | 02:39 |
| bdmurray | mjg59: Okay, that module is preventing me from suspending though and if it matches a lot of devices it seems like it might be a problem for a lot of people then. | 02:40 |
| mjg59 | bdmurray: Sounds like we need to fix the module. What are the symptoms? | 02:40 |
| bdmurray | When trying to suspend vi "echo -n mem > /sys/power/state" I receive a kernel erro message regarding "uvcvideo 5-4:1.1: suspend error -22" | 02:42 |
| mjg59 | bdmurray: Uh. Why are you trying to suspend like that? | 02:43 |
| bdmurray | line 39 of /etc/acpi/sleep.sh is what was failing and it wasn't very informative | 02:43 |
| bdmurray | So I was originally using /etc/acpi/sleep.sh | 02:44 |
| mjg59 | dmesg should give you the same information | 02:45 |
| mjg59 | Hm. Interesting. I can't see any obvious reason why that would fail. | 02:45 |
| bdmurray | I think it worked before this commit - 616d7243b60bb3eb2abed6cf99fe4d3edfc6a874 | 02:46 |
