Summary

Allow or block USB devices by class or VID:PID to secure endpoint peripherals.

Prerequisites

• Device with SnapOS 1.3 or Higher
• Administrator privileges

Procedure

1. Open USB Configuration
   • Start → Preferences → Settings → USB Configuration
2. Allow/Block by Class
   • Select class (Mass Storage, HID, Audio) → choose Allow or Block → Apply
3. Allow/Block by VID:PID
   • Under “Manual Rules,” click Add → enter VID:PID (e.g. 046d:0825) → select Allow or Block → Save

Advanced Configuration

• Deploy rules via zMAN to enforce USB policies across device groups.

Troubleshooting

• Devices still allowed: verify no conflicting “Allow All” rule is higher in order.
• Important device blocked: add explicit Allow VID:PID rule above class Block entries.
