[SOLVED] wrong keyboard after upgrade to kernel 4.14.52

[v_andal]

I've upgraded kernel using "make oldconfig". Compiled and installed - no problems. But after boot into Xorg I've discovered that
my mouse and keyboard are not working. After rebooting into old kernel I've compared Xorg logs. It appears that new kernel has found 2 keyboards and 2 mices instead of only 1.

I'm using Medion wireless keyboard and mouse. But they are connected to PC via USB dongle. So normally they appear as regular USB devices in Xorg. With new kernel Xorg sees additional devices with names like "MEDION keyboard" and "MEDION mouse".

Which new option may cause such behavior?

What do you have for INPUT_DEVICES in make.conf?

Finally, I've found the reason for the problem. There's new kernel option CONFIG_USB_PCI. When I did "make oldconfig" this option was not set, as result my USB devices didn't work. Enabling this option has fixed the problem.
