Unable to update firmware on OmniTouch 7

[eddy]

I just recently my first OmniTouch.
 
Out of the box, it is running version 1.01 and is functioning with the system (I can control lights, arm/disarm, control thermostats, etc.) but I have the "chuffing" noise so definitely want to upgrade the firmware/kernel.
 
When I go in to PC Access > Extended Setup > OmniTouch 7 Screens, I see the OmniTouch with the correct IP address. I click the "Update" button, select the "OmniTouch_7_Version_1.14_99A00-1_2.ot7f" file, and click "Open". I get the dialog asking me to make sure I selected the right firmware file, and then click "Next".
 
Then I get a screen that simply says:

Firmware File:

OmniTouch_7_Version_1.14_99A00-1_2.ot7f
134217756
3/18/2016 11:16:02

Disconnected. (Duration: 00:00:00)

 
I've tried this dozens of time. Sometimes the duration is slightly longer than zero (e.g. 00:00:00.0156001). The same thing happens if I select the older "OmniTouch_7_Version_1.12_99A00-1_2.ot7f" file.
 
I'm running the latest PC Access (3.15.0.803).
 
Any suggestions?

Wouldn't you know it... I got it to work.
 
I logged in to the switch and turned PoE off and back on to reset the OmniTouch 7, and after that, PC Access was able to apply both firmware updates.
 
The good news is the "chuffing" sound coming from the speaker appears to be muted during idle periods.
 
Here's hoping Leviton continues to update the firmware with some key features that are still missing (like H.264 support for cameras)...
