kinect fails to publish depth data #22

Open jeking04 opened 8 years ago

Not sure this is the correct place for this issue...

Recently we are having issues with getting the kinect properly started. In particular, when running

roslaunch herb_launch kinect2_bridge.launch

on herb2 we see a spew of this error:

[TransferPool::submit] failed to submit transfer: LIBUSB_ERROR_IO

And then no depth data published:

[ INFO] [1456415760.926092816]: [Kinect2Bridge::main] depth processing: ~infms (~0Hz) publishing rate: ~0Hz
[ INFO] [1456415760.926144961]: [Kinect2Bridge::main] color processing: ~0.102961ms (~9712.41Hz) publishing rate: ~26.64Hz

Rachel and I experienced this earlier in the week and I am seeing it again now. The previous fix was to unplug/replug the USB into herb2 and then reboot the whole machine. This has not worked this time.

Note: A quick google of the error shows many people having this problem. Some of the proposed solutions might work for us. I didn't try because I don't think I know enough about how we have herb2 setup.

Actually, I forgot one other step we did: rosclean purge. This seemed to do the trick now too. Perhaps we need to add something to do this regularly?

We should try upgrading libusb, as per @DavidB-CMU's post on Slack:

I took a look at the Kinect2 setup on HERB's computer. I think a step was missed when installing the driver. This may explain why the libfreenect driver or the USB port drops-out sometimes. $ apt-cache show libusb-1.0-0 says libusb-1.0-0_1.0.17, which is around two years old. v19 was the recommended version last year, now the iai Kinect2 guys are recommending v20. There's instructions at the bottom of this thread: https://github.com/code-iai/iai_kinect2/issues/91 Because there are important demos this week, I did not upgrade anything. I will leave that as an exercise to the reader :wink:
