very unstable with www.usb-over-network.com

[rusefillc]

https://www.usb-over-network.com/ is a commercial software offering transparent remove USB access

on my Windows remote client I see putty working reliably, also some other piece of software works with another non-CDC USB device, meaning usb-over-network somewhat functions

with jSerialComm I was able to establish communication and receive data only once - unable to re-connect

is there a way for me to enable verbose/debug mode to have some visibility into low level?
