Please keep in mind I'm not that computer savvy, but I will try any suggestion so please help me out!

My tablet will stop working if the USB connection is ever broken, or the Ubuntu software is being updated. Sometimes it will stop working for no reason that I can see. The lights will still be on, but it won't be responsive. It doesn't work again until I restart the laptop with the tablet plugged in, which is grating if you have to do it every 25 min. or so... I'm not sure if the issue is with the port, the tablet/cable or the driver but any suggestions would be very welcome!

Also, MyPaint is frequently having hiccups. It seems to save fine but at times it will randomly close down and when I open files they're often empty. They turn into 0Kb files and only contain a single empty layer. Also very grating, considering I lose days of work for no clear reason and without any heads up. Again, I'm not sure if the issue is with the port, the tablet/cable or the driver but any suggestions would be very welcome!

The error message reads;
