I was able to fix the issue by changing the IO_WATCHDOG_DELAY in ohci- hcd.c from 250 msec to 275 msec. I suspect that the new timer wheel based timers in 4.8 have exposed a bug in the ohci driver. Before the io watchdog timer was set to 250 with 20 msecs of slack time. This is more than likely just a hack work around but I'm able to use my usb headphones now. Here's my diff
