Summary: Use Windows PowerShell to show attached USB drives.

 Is there an easy way with Windows PowerShell to show all drives that are connected via USB?

Use Get-WMIObject and query win32_diskdrive:

GET-WMIOBJECT win32_diskdrive | Where { $_.InterfaceType –eq ‘USB’ }

Or…

Write this as a query and pass it directly to WMI:

GET-WMIOBJECT –query “SELECT * from win32_diskdrive where InterfaceType = ‘USB’”
