Using Sparky v5.3 Mate on two computers
Laptop: Lenovo Thinkpad T450s - Processor Intel Core i5-5300U, Graphic Intel Mesa 5500.
Desktop: Processor AMD FX-4100 Quad core, Graphics nVidia GF108 (GeForce GT430)
Both computers are have been updated as of today's date.
I also have a Samsung Galaxy S4 GTi9506 mobile phone.
If I plug in the Samsung to the Desktop computer nothing is displayed. On the other hand, plug it into the laptop and I get a display of the Samsung operating system and all the files.
I have tried all USB connections on the Desktop, in the hope that it would be a fault in one of them - but it wasn't.
Can any member give me a possible explanation for this, please. It is very annoying, as I use my desktop constantly and normally only turn on the laptop each morning to update the system, unless I am going away from home.
For some unaccountable reason, although I get a message that the Samsung device cannot be opened, eventually I now get the Samsung icon on the desktop and can access all the files I've tried it about a dozen times, with success, so have marked the problem as Solved.
