ttyUSB0 seen by guest but no characters or data in or out

Good morning or afternoon,

I can see my ttyUSB0 in the host and send and receive data all day but ...

... when I disconnect the device from the host and connect to a Linux guest ... everything seems fine but I can't get or send data.

(both host and guest are Ubuntu 16.04)

(Workstation Pro 12)

lsusb on the guest yields:

Bus 001 Device 005: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303]

On host:

Bus 003 Device 002: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303]

Any ideas?

I see /dev/ttyUSB0 disappear from host and appear on guest when I connect to guest and visa versa when re-connect to host.
