port X disabled by hub (EMI?), re-enabling...

[kermitas]

Hello,

for a past 7 days I am fighting with:

Code: Select all

 hub 1-0:1.0: port 1 disabled by hub (EMI?), re-enabling...

I have a Microsoft LifeCam Cinema. It works from about 1 minute to 4 hours and then I it randomly disconnects. I tryed soft usb hub restart usb_modeswitch -v 0424 -p ec00 -R -W but nothing helps. Camera disappear on lsusb list (after that there is no /dev/video0 any more). To make it work again I have to manually unplug and plug USB again.

I checked and replaced everything 1000 times (r-pi, cabel, power, usb hub, sd car, Debian Wheezy, F17, libjpeg62, 7 and 8, I have also compiled my own 'motion', I did rmmod uvcvideo && modprobe uvcvideo, I have used quirks=128 FIX_BANDWIDTH as it is mentioned here http://www.ideasonboard.org/uvc/) and scenario is always the same!!

I am using 'motion' to motion detection digging a little security system for my home.

Gues what? Camera works fine with my laptop .

I also have second webcam: Logitech C270. This webcam works with r-pi+motion for many many days without a problem.

Microsoft LifeCam Cinema has 1.5m long cable without EMI noise cylinder (there is no anything like that http://www.sourcingmap.com/emi-noise-su ... 26796.html).

Does anybody know what I can do with his bug?
How can I do to tell usb hub not to disconnect my camera?
Can it be really some electromagnetic interference??

I am desperate, what can I do? Where to look?

Thank you very much,
Arthur.

Today I did some tests.

I am starting to be shure that by putting cell phone (with active phone call) near r-pi you can:
- disconnect Microsoft LifeCam Cinema usb webcam (sometimes it will back shortly, sometimes it newer returns - I have to manually unplug and plug it again)
- stop network transmission for a while (ethernet is related with usb so it also stops 'motion' from capturing new frames, after few seconds network transmission - for example ping, ssh - back)
- completely hang r-pi

I also tryed to put drill near webcam or usb cabel and sometimes it disconnects.

I used also walkie-talkie. It stops network trnasmission for a few seconds but did not disconnect webcam (once it hanged r-pi).

I don't want to say that all my problems with disconnecting webcam was electromagnetic interference. I need more tests. My camera semms to work longer at night and disappear more frequently during the day (once again, is it EMI?). Now I had put r-pi into metal box and will see how long it will work with webcam.

My second problem with LifeCam (jumping horizontal linest) I described here http://www.raspberrypi.org/phpBB3/viewt ... 63&t=12304.

If anybody had a problem with "port X disabled by hub" please let us know how to fight with is.

Thank you,
Arthur.

I have the same camera and the same problem - but not only disabling the hub arise, also my ethernet device will get dropped down, weird ...

I did some debugging and found an error within the ffmpeg package ... I'm still guessing, not knowing

Is ffmpeg_cap_new within motion.conf disabled or enabled? If you did enable it, please switch it off and try again ...

I forgot to mention that raspi isn't crashed, there is no ethernet device anymore ... If you restart the network from the console, raspi is "alive" again ...

After many days of fighting I am giving up.

What is the best in Microsoft LifeCam Cinema + RaspbeeryPi is ... not to use this webcam with rpi!

I bought and used two EMI ferrite cilinders, I replaced USB cables, usb hubs, raspberrypi (even inside metal box - EMI), OS (debian wheezy, F17), SD cards, power supply, I used 'motion' / fswebcam / v4l4j ... nothing helps. This webcam hangs my rpi or is disconnected by the hub.

I can't do nothing more . I have only wasted a money buying this webcam to use it with rpi.

Now I bought Creative Live! cam socialize HD 1080 and it works out-of-the box. It works for many days without any problem!

Sometimes my ethernet wend down and up in a few seconds. Camera disappear but rpi didn't crash.

From this what I know I don't have any ffmpeg installed so in my case it is not a reason of all that troubles.

I never create a movies on rpi. Just take snapshots every 10s and on motion detection.

Latest motion 3.2 or trunk557 works quite well. Yesterday I switched off motion detection and changed to take snapshot every 1s. Now it works even more stable.

I hate M$ LifeCam Cinema webcam. I loosed sooooo manyyyyy days . M$ support responded to me that this webcam should be used only with Windows and aksed me for registration key. (For many years I am a 100% linux guy and their webcam is UVC class device so it should work with non-ms products. )

If you are interested: I also described here http://www.raspberrypi.org/phpBB3/viewt ... 63&t=12304 jumping horizontal lines when using M$ webcam.
