Is USB Available at all?

[MikeiLL]

Playing around with PyUSB a bit to see if it offers some insight. I installed libusb1 on the Mac via Homebrew. Does any of the below offer any insight?

# got these using the command lsusb -vv
VENDOR_ID = 0x0483
PRODUCT_ID = 0x5740
DATA_SIZE = 1

device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)

>>> device
<DEVICE ID 0483:5740 on Bus 020 Address 014>

>>> device.is_kernel_driver_active(0)
False

>>> device.set_configuration()
Traceback (most recent call last):

The Vendor ID and Product ID declared here are for a completely different device.
