MT300N V2 USBIP doesn't work

Error subscription: Atter installing usbip without error, can’t start it:

Thank you.

It seems to me that the files are missing:
ls: /lib/usbip: No such file or directory
ls: /usr/bin/usbip: No such file or directory

same here. i’v so far failed to find suitables packages to install with the latest version.
