One possibility is that something (like a windows editor) has introduced invisible wierd characters into the loadusr line.

Running Linux Mint nothing windows related on my end or do you mean on the end where this was compiled?

Is it worth seeing if you have more than one version of the module on your PC?

(It might even be worth re-compiling the module)

Sorry Ive been out of town for a few days.

Only one module yet I may try to recompile it at some point. That would take some serious effort as it is a bit outside of my scope of knowledge at the moment. Im game for trying it though.

Right now I am sorting out hooking it up through TB4. If I determine I do not like this method I may do exactly as you said. Yet for the moment I want the machine running to get me to the next stage.

If I need to I will buy another Huanyang as I really like the modbus configuration then figure out the recompile for the wj200. I really would love the wj200 on modbus so that is the goal in the end no matter what. For me its not a waste of money to have a cheaper backup as I always want backups on hand. I am that way with everything, especially electronics. I fly FPV acro drones, let me tell you it really sucks to not have the parts on hand after a crash LOL!
