i2cdetect -l
non i2c bus....

---

Summary

through this usbip server. I did can control the CP2112 GPIO. but the i2c bus did not trans out.

P.S
1, I try to control at the local OS (macOS), It fine.
2, I try to use the virtualhere server at macOS and the virtualhere client at windows10, is fine too.
3, I try to use the usbip-win server at windows10 and the usbip client at this ubuntu, is fine too.

thanks a lot to help

It is possible that the SMBus feature uses something not well-implemented.
