- why hardware off-loading does not work for that interface?
- why switch ACL rules cannot be applied to that interface?

- how to connect both USB disk and network card to one port?
- why USB port extender draws so much power?
- why my XYZ branded very cheap card is not recognized but it works with my Windows/Mac?
