USB Error while running a Docker Container

[SimeonOA]

I am running a Docker container application that uses libfreenect2 in a system/setup with eight computers running Ubuntu 18.04 and a Kinect connected to each of the computers. All computers are running the same version of the application and were set up alike. The USB is USB 3.0.

I keep seeing this error on two of the computers:

[Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_TIMEOUT Operation timed out
[Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_TIMEOUT Operation timed out
[Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_TIMEOUT Operation timed out
[Info] [Freenect2DeviceImpl] stopping...
[Info] [Freenect2DeviceImpl] canceling rgb transfers...
[Info] [Freenect2DeviceImpl] canceling depth transfers...
[Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_TIMEOUT Operation timed out

Disconnecting and reconnecting the USB usually fixes this for a short while before the issue develops again.

I have looked at similar issues: 546, 547, 915, 831, 458 and the troubleshooting tips here.

I tried increasing the USBFS buffer size to 64 and 128 but this had no effect.

Disabling USB autosuspend worked for a longer period but the error still developed.

Do you have any suggestions on what might be wrong or what I could try?

All the other computers are working without this error and have the same buffer size and settings as the two which have this error.

Thank you.

Just guessing, but I'd say there's two possible causes:

• if the computers are different (i.e. different USB3 host controllers in particular): bug in the HC silicon and/or driver
• if the computers are identical: problems with the USB3 cables
