7841 Phone Shuts Down Immediately - Cisco Community

Hi Cisco community

We've got the problem, that the cisco 7841 phone shuts down immediately after connecting the jabra headset with the computer over USB.If we do not use the usb-connection between the jabra headset and the computer, the phone and headset are working perfectly.

Switch: Cisco WE-C3560X-24P-E 15.0(2)SE8Phone: Cisco 7841 11.5.1-18 (connected on port gi0/17)Headset: Jabra 9450

Below you see the debug ilpower during connecting the headset with the computer:

We tried power inline consumption 15400 and power inline static 30000 on the port, but that doesn't help:

Does anyone knows how to fix this problem?

Thanks!
