Can guest OS access hardware feature that is not supported by host OS?

Let's suppose a system with following configuration for example:

• Hardware: Has USB 4.0 controller and port
• Host OS: Windows 10 (Doesn't support USB 4.0)
• Guest OS: Linux with kernel version 5.11 (Supports USB 4.0)

Questions:

1. Is it also necessary for hypervisor to support USB 4.0 to use the feature?
2. If the hypervisor supports USB 4.0, would Linux get full 4.0 speed from attached device, say ext SSD, from the config above?

I guess the question boils down to whether VM gets direct access to attached devices or not.

Thank you.
