python
import subprocess

def check_usb_device(device_name):
command = f"devcon find * | find \"{device_name}\""
result = subprocess.run(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
return result.stdout.strip()

# Example usage
device_to_check = "My USB Device"
output = check_usb_device(device_to_check)
if output:
print(f"USB device '{device_to_check}' found!")
else:
print(f"USB device '{device_to_check}' not found!")

In the above code, the `check_usb_device` function takes a `device_name` parameter and searches for it using the `devcon` command-line tool. The output of the command is captured, and if any output is found, it indicates that the USB device is present.

Note that this code requires the `devcon` utility to be installed on your system and accessible via the command line. Additionally, the code assumes that the `devcon` command can correctly identify the USB devices on your PC.
