Hi Chris
Thank you for answer.I asked that question because I found on the internet, the
pyUSB code changed by CISCO.
https://developer.cisco.com/site/eiot/documents/pyusb-dev-guide/?python#cisco-pyusb-hello-world-programRegistration
is required to access the codeA key change was that the function find () has
been modified to accept the mac address as a parameter instead of IdVendor. The
code below was copied from the CISCO's site:
import usb.core
import usb.util
# find device with Mac address of the PoE to USB adapter
dev = usb.core.find(address=int("0022bdcf3600", 16))
I tried using this code but an "segmentation fault" error occurredI apologize
for not being able to help. I am new to python and I thought someone might have
integrated the Cisco modifications to the original pyUSB.I think it would be a
good idea the possibility to read USB ports remotely.
Best regards,
Heilan Percio Cardoso

Is it possible to read a USB port remotely ? How can I do this?
Simple answer is no, this is an application issue and not related to pyUSB. I'd
recommend asking on a general Python mailing list. That being said, the two
options that I can think of off the top of my head are:
1) remote access to NFC reader from cloud (i.e. pull)2) NFC reader machine
contacts cloud application (i.e. push)
For #1 you would design a proxy server in your application OR use an off the
shelf generic option like RPyC https://pypi.python.org/pypi/rpyc. I've used
RPyC as a simple proxy solution for other libraries and it does what it says it
does.
Either way you will want to ensure the communication line is secured somehow!
