What would be the Mac command to connect to that if the machine were, say, 10.211.55.1?
Open a terminal, change the working directory to where the command-line utility (eveusbc) is located:
Connect to your shared device by doing the following:
1) find all USB ports shared on your remote server:
eveusbc explore [remote-host]
replacing [remote-host] with the IP address or network name of your Windows system.
2) establish a connection with one of the discovered devices:
eveusbc connect [device]
replacing [device] with the output of the "explore" command corresponding to a particular device (omitting the word "remote" in the beginning).
