de0-nano-soc USB OTG Keyboard and other

Hello! 

I have a de0-nano-soc, according to the manual, everything worked fine, but I need to try to connect the keyboard or mouse to the USB OTG. 

What was done for this: 

1) in soc_system.dts - added in usb1: 

status = "okay" 

dr_mode = "host" 

2) in settings kernel:

But I could not get input from the keyboard. 

Here's what it produces when connected: 

usb 1-1: new low-speed USB device number 4 using dwc2 

usb 1-1: New USB device found, idVendor=046a, idProduct=0001 

usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 

input: HID 046a:0001 as /devices/platform/sopc@0/ffb40000.usb/usb1/1-1/1-1:1.0/0003:046A:0001.0003/input/input2 

hid-generic 0003:046A:0001.0003: input,hidraw0: USB HID v1.11 Keyboard [HID 046a:0001] on usb-ffb40000.usb-1/input0

Now I went another way. Loaded the ready Linux LXDE for de0-nano-soc, launched X11.  

When I connect the keyboard, I see that it is defined, but the text is also not entered. But I see that, the input is with the process: 

cat /dev/input/event1 

I understand that he uses the keyboard from the computer itself, which is connected to the SSH ttyS0. 

How do I now start the input with event1?
