Comment 6 for bug 1529077

I have tested with the following kernel:

Linux computer4 4.4.0-040400rc7-generic #201512272230 SMP Mon Dec 28 03:32:16 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

The behaviour is the same as with Linux computer4 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

This means the problem persists.

Relevant lines from the syslog with the rc kernel:

Jan 4 19:14:57 computer4 kernel: [ 219.001128] usb 3-1: reset high-speed USB device number 2 using xhci_hcd

Jan 4 19:29:10 computer4 kernel: [ 1071.599601] usb 3-1: reset high-speed USB device number 2 using xhci_hcd

More precise description of the problem (for both the distribution kernel and 4.4.0-rc7):

If I start the CD player application with no disc inserted, it does not hang. But when I then insert a disc, it hangs for approximately 30 seconds and the disc is not detected at all.

If I start the CD player application with the same disc inserted, it hangs for approximately 30 seconds and then the disc is detected.

Once the disc has been detected it can be played normally by the CD player application.
