Re: [Pyusb-users] PyUSB how to set the ControlOutput message ?

From: Romain A. <r.a...@gm...> - 2010-01-22 14:28:05

Yes I did both sniffing, from linux with usbmon and from windows itself with
usbsnoop.
What I didn't do is starting sniffing when I plug the device, I always
started sniffing before pressing the "download data" button under windows
when the device was already connected.
Sorry to fulfil the mailing list with log files... :(
This first log file is from windows running usbsnoop when I plug the device.
I don't know if this traffic is generated from windows querying the device
or from the device driver initialising the device.

The second log file, always from windows, is when I press the "download

and the previous one on the usb port.
