Can someone explain how I would read the data from the USB "port"? I
don't know if it matters, but I am trying to read the data from a GPS
plugged in to the USB port.
Thank you,
Robin

Just a guess, but can you use pyserial to talk to USB001?

You can't. There's no such thing from a SW point of view. ;)

It's probably a serial device. Try using pyserial to talk to
/dev/ttyUSB0.

Have a look for PyUSB - there are (confusingly) two different packages
called pyUSB. one interfaces to FTDI chips connected to a USB port: http://bleyer.org/pyusb/
The other uses libusb to interface to devices generally under windows: http://pyusb.berlios.de/

USB is a "protocol" bus. It isn't like a serial port, where you can just
start reading bits. Each device has one or more "interfaces ", and each
interface has one or more "pipe" for transmitting data. You have to know
which "pipe" to talk to, what kind of pipe it is, and how to force the
device to send before you can talk to it.
On the other hand, as someone else pointed out, many types of USB devices
fall into standard device classes, and the operating system supplies
drivers for those classes. If your GPS device is in the communication
class, you might be able to pretend it is a serial device.

The problem comes in when the server is stopped before the client, in which

This is how it works:

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
