Make sure you're telling Subsurface to connect to the correct device. On my
computer, and many other Linux systems with many dive computers, it's
/dev/ttyUSB0, but it may be different for you. One way to find out what the
device is called is to look at the system log file. On Ubuntu, I think it's
/var/log/syslog, but it may be /var/log/messages. At the command prompt,

sudo tail -f /var/log/syslog

sudo may or may not be necessary, depending on permissions.

This will monitor the log, and display the last few lines of the file.
Then, plug in your cable, a bunch of new lines should be logged. From this
you should be able to work out the correct device. From this you should be
able to work out the correct device. As an example, taken from Appendix A
of the user manual:

usb 2-1.1: FTDI USB Serial Device converter now attached to ttyUSB3
usbcore: registered new interface driver ftdi_sio

This tells you that the device is /dev/ttyUSB3, and the kernel driver is
ftdi_sio. In subsurface, when you download from dive computer, enter
/dev/ttyUSB3 (or whatever you get) as the device.

Let us know if this helps.
