USB Configuration¶
FlexKVM emulates a keyboard, mouse, and storage device via USB. You can customize the device identity — what name and vendor info appears in the target host's Device Manager.
Go to Settings → System → USB Configuration.
Switch Device Identity¶
The dropdown lists built-in identities and any custom ones you've created. After selecting, USB auto-restarts to apply the new configuration.
