I purchase USB3 dual-hard-drive docking station from Fry Electronics called the Dyconn Dubbler Dock.
When I plug this device into an Ubuntu Linux 15.04 laptop (kernel: 3.19.0-26-generic), I see no indication that I've plugged it in. When I plug it into a Windows 10 workstation, the hard drive (plugged into the dock) auto-mounts under "This PC" (drive E).
I know a few commands for hardware detection on Linux, but each command I know outputs the same output whether I have the device plugged in (and on) or not.
For example, with the device plugged in (and on, with a hard drive docked), I ran this command:
sudo lshw > ~/Desktop/hardware.txt
Then, with the device unplugged, I created another file like this:
sudo lshw > ~/Desktop/hardware2.txt
I used Meld to compare these two output-files, and they are identical.
Even if there are no Linux drivers for this device, I'd still like to report some information about the device to kernel.org, to help towards it eventually working with Linux. But none of the commands I know seem to detect its existence.
