Try this. Unplug the device and open a terminal and type
Plug the device back in. Is it recognised ?
echo -1 | sudo tee /sys/module/usbcore/parameters/autosuspend
Also unplug your Ubuntu machine so it is totally disconnected from any power. If it's a laptop also remove the battery.
Lean for 10 minutes. Plug the machine back in and start up Ubuntu. Plug the device back in. Is it recognised?
I have to be honest, i don't expect either of these ideas to work in your case but it is always worth trying.
