I have a problem with mouse and keyboard on my raspberry pi.
When I connect two usb device they don't work and if I go in /var/log/syslog
I found this error:
mtp-probe: bus: 1, device: 6 was not an MTP device
If I make lsusb I see both the devices as recognized
Kernel 4.14.44-v7+
And I tried, at the starting before the boot, to press on my keyboard shift for start recovery, and in this moment mouse and keyboard works, so I exclude a USB hardware error
How can I resolve this problem?
