Fedora-23 does not see my USB ports, but Fedora-24 beta does: =========================== [tim@william ~]$ cat /etc/fedora-release Fedora release 24 (Twenty Four) [tim@william Tel]$ lsusb Bus 002 Device 003: ID 17ef:1003 Lenovo Integrated Smart Card Reader Bus 002 Device 002: ID 8087:0020 Intel Corp.

I'm running F-23 and F-24 (beta) on separate partitions. 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. F-24 seems to be running fine now, so it is not a critical issue. (There were some problems with kmail under F-24 originally, but I think they have been sorted out.)

I suppose that I would run "strace -o somefile lsusb" on both the F23 and F24 system to see if something obvious pops out. Before that, I would also run lsusb as root on the F23 system for kicks.
Well if I were you I would start by Googling “usb hot plugging linux Fedora 23” then for “24” and possibly look into how UEFI secure might affect what systems/modules are signed and therefor loaded.

Or maybe it isn't signing. Maybe it is the state the device is left in by the driver at reboot time. Try booting into f23 from a completely powered down state and see if it recognizes the device then (just to gather data points :-).
