Doing a small modification on the built-in Port: USB report to filter only by assets with a Type C USB port:
Select Top 1000000 tsysOS.Image As icon,
tblAssets.AssetID,
tblAssets.AssetName,
tblPortConnector.ExternalReferenceDesignator,
tblPortConnector.InternalReferenceDesignator,
tblAssets.Domain,
tblAssets.Username,
tblAssets.Userdomain,
tblAssets.IPAddress,
tblAssets.Description,
tblAssetCustom.Manufacturer,
tblAssetCustom.Model,
tblAssetCustom.Location,
tsysIPLocations.IPLocation,
tsysOS.OSname As OS,
tblAssets.SP As SP,
tblAssets.Firstseen,
tblAssets.Lastseen
From tblAssets
Inner Join tblPortConnector On tblAssets.AssetID = tblPortConnector.AssetID
Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
Inner Join tsysOS On tblAssets.OScode = tsysOS.OScode
Left Join tsysIPLocations On tblAssets.LocationID = tsysIPLocations.LocationID
Where tblAssetCustom.State = 1 And tblPortConnector.PortType = 16 And tblPortConnector.ExternalReferenceDesignator like '%Type C%'
Order By tblAssets.AssetName
