Peripheral Device Serial Numbers

USB devices and monitors were previously discovered without serial numbers or appeared as duplicates during agent-based Windows scans. The sensor now extracts serial numbers from Device IDs, deduplicates entries using the Device ID as a unique key, and uses a three-tier fallback for monitor detection (WmiMonitorID > Win32_DesktopMonitor > USB DISPLAY entries).

Where the fix appears

The improved peripheral data is visible in the following locations:

Location	What changed
CMDB > Windows Host CI > Peripheral Devices tab	USB devices and monitors now show serial numbers with no duplicate entries.
CMDB > Peripheral Device CI > Detail page	Individual peripheral CIs have accurate serial numbers and model information.

Procedure

Complete the following steps to populate peripheral data for existing Windows hosts.

1. Update the Discovery Agent.

   Deploy the updated agent to Windows hosts where peripheral discovery is needed.

2. Re-run the agent scan.

   Trigger a new scan to collect peripheral serial numbers.
