USB connection failed

Hello, after firmware update, the USB HID connection between PC and printer is no longer functional. Windows tell me the “USB device is not recognized”. the actual firmware is 1.2.1 , the old one was Oct 18 2017 version.
Printer type = VX
Could someone give an advice?
Thanks!

I have the same problem (first time to connect the USB).
Firmware 1.2.1

Are there some drivers or something I need for this?
