This "HcDoneHead not written back; disabled" bug also affects me with
the device "ID 08bb:27c4 Texas Instruments" on the 4.8.4 Kernel from
Ubuntu mainline. With the kernel 4.7.10 it works without problems.

  specific USB devices disconnect and don't reconnect

Bug description:
  2 USB ports randomly disconnect and don't reconnect (it's always the
  same two), and in dmesg all I get is

  [ 1276.916458] ohci-pci 0000:00:12.0: HcDoneHead not written back; disabled
  [ 1276.916467] ohci-pci 0000:00:12.0: HC died; cleaning up
  [ 1276.916553] usb 3-1: USB disconnect, device number 2
  [ 1277.017302] usb 3-2: USB disconnect, device number 3
  This only started happening when Yakkety went to the 4.8 branch, with 4.7 
branch this doesn't occur, hence the bug report since it's unlikely that a 
hardware failure will only stick to one OS and one branch of the kernel for 
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested 
that in the past couple of days)
