TPM Passthrough with QEMU fails

I am running Ubuntu 16.04 and I have installed the following:

qemu - version 2.5
qemu-kvm - version 2.5
libvirt - 1.3.1-1
virt-manager - version 1.3.2-3
virt-viewer - version 1.0-1
trousers - version 0.3.13-4
tpm-tools - version 1.3.8-2

I prefer to use Linux, but need a Windows platform with a virtual digital badge for work and would like to run it in a VM. Once I create the VM and add the TPM device, I get the following error:

Unable to complete install: 'internal error: process exited while connecting to monitor: 2016-08-17T23:57:55.383617Z qemu-system-x86_64: -tpmdev passthrough,id=tpm-tpm0,path=/dev/fdset/1,cancel-path=/dev/fdset/2: '/dev/fdset/1' is not a TPM device.'

The path is correct in virt-manager when the TPM device is added, but the error shows the path to be /dev/fdset/1 and the cancel-path to be /dev/fdset/2. The cancel path should be /sys/class/tpm/tpm0/device/cancel, but cancel does not exist there. Below are some outputs from tpm_version and dmesg | grep -I tpm:

Before trying to add the TPM device, I stopped and disabled trousers. Any help would be appreciated. Thank you in advance!
