As I already wrote many times (and you just noticed), Hantek's USB drivers are a mess. Try to do this: Open the Windows Device Manager and mark the option "Show hidden devices" in "View" menu and then remove all Hantek drivers that you see (when you are deleting a device form the list, make sure to check the option "uninstall driver").
Unplug an plug the device again to confirm that there is no driver left in the system. When you see only the yellow exclamation mark, download the latest drivers from Hantek and manually install the Win 10 driver (in the Windows Device manager right click on the device and select "update driver").
Also try to plug the device in a different USB port and make sure that both connectors of the USB cable (black and red) are plugged. Oh! and don't use any USB hub, I don't know why but hantek's USB drivers don't work through a hub, you'll get a blue screen and the computer will crash and reboot.
Regarding the button at the back, it is simple: keep it pressed (H position) to use the oscilloscope with Hantek's USB driver and software. With the button in the position P (unpressed) the device will use the fx2 usb driver, this way you can use the Saleae Logic software for the logic analyzer (limited to only 8ch but way better and much more useful than the original software). You need to unplug and plug the device again to the usb port every time you press the button for it to work.
