Operation with pen and touch works quite well, but the tablet makes me phantom entries, although the pin is far enough away. Could possibly be due to a bad USB extension cable. Such problems have been then just when the manufacturer operates a cable mitliefert, which is far too short for use on the desktop PC. In addition, the connection of the cable is far sunk into the device, so you simply can not use a longer replacement cables (there are almost always the plug too thick - the AmazonBasics cable fits at least definitely not, even after removing the cover).
Thus, since only helps a stroke or Gefrickel with an extension. Extremely annoying.
Addendum: The Belkin USB 2.0 Hi-Speed fits into the socket, if one removes the cover to the tray, or sawn to fit. Belkin USB 2.0 Hi-Speed charging and sync cable (USB plug A / plug Micro B) 1.8 m
