I don't know about Mint but in Ubuntu there is a similar problem with permissions to the device. In that case, Ubuntu thinks every serial device (which is what is inside the USB plug after all) is a modem and assigns permissions accordingly on plug in. The permanent solution is not to change the ownership/permissions of /dev/ttyUSBx but to add the user of subsurface to the group that is allowed to create dial out connections on modems. That would be

sudo useradd -G dialout username

where "dialout" has to be substituted by the appropriate group name, find out with 

ls -l /dev/ttyUSB0

and username of course by the username.

Unfortunately, I cannot help with the actual download problem. But I am sure, others (Jef? Miika?) can.

Best
Robert
