DA45: Cisco 9971 Resets After Pressing Call Control Button

Why does the Cisco 9971 phone reset when I press the call control button on a USB-connected DA45?
There is a known issue with the DA45 with firmware rev90 and the Cisco 9.3.2 firmware.  DA45’s with older firmware ver58 will work as expected.
