That's not the same; libusb is doing the low-level handling for you.
That's not the sense of "device driver" that gets really close to the
metal. I'm talking about real-time response to signals, I/O port and
interrupt handling, that kind of thing. The device driver will then
expose a higher-level API, maybe as a /dev/something openable, and
Python can control the device using that.
And that's something that Python *is* good at. I wouldn't use Python
to write a device driver for an RTL8169 card, but if I have that card
in my computer, I will totally use Python to create a network
connection and transfer data. I'm just not going to concern myself
with the low-level details when I do. :)
