Hi,
In these days I am working on pyusb to establish a connection between my
laptop(Windows 7) and one FX3 hardware.
The first thing I must do is to download the firmware,but I met some
problems.The downloading process is easy to describe,and I am sure about the
.img data is writen to FX3 RA

Hello...
I'm new to python (and pyusb).
I try to port some VUSB device to work with python, but get at trouble
in beggining. I can't send bytes...
here is my example (stripped from manual...)
import usb.core
import usb.util
from array import *
dev = usb.core.find(idVendor=0x16c0, idProduct=0x05
You are right: Kindle is recognized as a simple mass-storage device.
I have the kindle touch to experiment with, but actually I need to
communicate with the Atmel STK 600 with Atxmega 32A4U. I've found a
simple example from Atmel and they offer a dll with 4-5 function which
are really simple.

Do you know what's wrong?

Hi everyone,
I'm testing PyUSB right now and tried this example:
>>> msg = 'test'
>>> assert dev.ctrl_transfer(0x40, CTRL_LOOPBACK_WRITE, 0, 0, msg) == len(msg)
>>> ret = dev.ctrl_transfer(0x40, CTRL_LOOPBACK_READ, 0, 0, len(msg))

Thanks for reply:
I am trying to write to it. Sorry - there was an error in the snip-it I
posted.
I believe ctrl_transfer is defined as:
ctrl_transfer(RequestType, Request, Value, Index, Length, Timeout)
Corrected code
msg='\x00\x01\x01\x01\x00\x01'
dev.ctrl_transfer(0x40, 0x03, msg, 0, len(msg)

Hi,
I have been working with a Toradex Oak 4-20mA sensor. Using PYUSB I can
read from this device, but I would like to write to it such that I can
identify an individual sensor by flashing the LED or modifying its name. I
am running on Ubuntu 10.10 with Python 2.6.6 with PyUSB1.0
