I really need a second set of eyes on this as I seam to be missing something and I have been struggling with this issue for a good time.

I have 3 snow blowers with 3 channels each. ID 11, 22, 33

I purchased a Hasen DMX-USB Dongle and it works perfectly on my PC.

I plugged it into the Pi and in the FPP UI Output/Other I added it as shown below. No output to the snow blowers.

I read in a post that I needed to add a controller in xLights as FPP and upload it. Tried this and no change.

What a I missing?

Having a dongle on a Pi in FPP is actually not that easy a process in Xlights. I think that the main problem that you have is that in FPP you have the dongle starting on channel 1 and not channel 7142.
I would probably have the "dongle" setup set as an ethernet controller with DPP on the FPP IP of 192.168.2.207. Uploading the channels to the Pi would then kind of work and you would still have the dongle setup on the "other" tab.
You may be better off with the Pi configured as an FPP player only.
I have a dongle on my master player and have a fake e1.31 controller setup for it. This allows the FPP connect to upload channels to my Pi and in FPP I assign an opendmx dongle similar to what you have done. I manually turn off the e1.31 output to the controller that doesn't exist.
I'd love a better option but this is how I've managed to get it working.

RPI-28D+ get one of these and a PI and then you have 4 DPI outputs and DMX out without the hassle - hansonelectronics sells these, they are far more superior to the usb dmx dongle
