Python - infi.devicemanager usage help needed

Question

I am quite new to programming and have written a simple piece of code to check for the presence of a specific name within the windows device manager.

I am using the following library https://pypi.org/project/infi.devicemanager/

my function:

def searchdongle():
    found = 0
    devicesname = ""
    dm = DeviceManager()
    dm.root.rescan()
    devices = dm.all_devices
    for device in devices:
        #print(device)
        devicesname  = device
        print(devicesname)
        #if devicesname == "<Gaurdant Code>":
        if "Gaurdant" in devicesname and "Code" in devicesname:
           found = 1 
           print("Found it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!")
                
    return found 

But I cannot detect the name at all. I believe this is because Device is of type "Device" and not a string??? how would I cast this to a string to test??? I did try using the python IN operator but got the error TypeError: argument of type 'Device' is not iterable

testing both print statements yields the correct results:

resulted output

Any help appreciated thanks
