OK, I got it.
In the file /etc/defaults/openhab2 you should see a line like this EXTRA_JAVA_OPTS="-Xms250m -Xmx350m"
It needs to be changed to this (using sudo) EXTRA_JAVA_OPTS="-Xms250m -Xmx350m -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB1"
sudo systemctl restart openhab2
to use the new settings. You should then be able to select /dev/ttyUSB1 and see logs similar to this. Of course the baud rate should be 57600 and Software flow control.

Ok, something new. After changing the EXTRA_JAVA_OPTS to what Bruce suggests, Now the Ember EM35x has changed from UNKNOWN to OFFLINE-COMMUNICATION_ERROR.

What is your baud rate and flow control? Should be 57600 and Software
I did a fresh openHABian install and only added HABmin, zwave, & zigbee.
Who knows? another OH restart couldnāt hurt.
OK remover the UDEV rule, now restart and have option for ttyUSB0 and 1 (not the -5 and -55 that showed up after the UDEV rule)
Set to /dev/ttyUSB1, 57600, and software (XON and XOFF)
and still OFFLINE - COMMUNICATION ERROR
The raspberry Pi has four USB connectors, Should not matter which one I use?
And I saw a post on another thread that said to install the SERIAL binding, so I have that and the ZigBee binding installed. Have not tried Z-wave yet.

WOW, Hey guys, I finally decided to try to add the Z-wave binding and controller, and it went all good with controller ONLINE right away.
So I thought, why not delete the Ember EM35x and reinstall, I did and it finally came back and is status ONLINE.
Thank you all for your patience and help.
Sorry about that. Force of habit.
If you do not think you will need zwave I have a theory I can try. I suspect I should have added /dev/ttyUSB0 to the EXTRA_OPTS even though it is technically not needed. Since my system os for test, I can easily blow it away and try again.
If you expect to need Z-Wave you can leave it as is.
I used this stick for Z-Wave for many months on Home Assistant and openHAB until I was given another Z-Wave stick to test & keep.
When I migrated from a Pi 3 to a Hyper-V Debian VM on my sonās server, I decided to use the other stick for production and use the Pi and HUSBZB-1 for testing.
Where are you located? I have worked some with a Z-Wave vendor to get their devices into our database. in OH Zigbee and Zwave bindings are written by the same developer (Chris Jackson).
OK, great. I am in Virginia. Zooz and their online store thesmartesthouse.com have been working with a couple of us here to insure all of their devices are supported in our database.
Their prices are quite reasonable and their support is stellar. I have had a couple of defective devices replaced with no questions asked. In fact, in one case, the issue was an incorrect manual instruction and not a hardware failure.
