I used to see the USB ports under F-23. The change happened more or less when I installed F-24, though I can't see how that could have caused the USB loss. F-23 and F-24 share my /home partition, so it is conceivable that some change there could be the cause. Also the bootloader in /dev/sda presumably changed with F-24 installation I'm afraid I'm completely ignorant of USB software. I couldn't see what kernel module, if any, deals with USB. Any suggestions or elucidation gratefully received.
