Thanks for your replies.
First of all: I'm using the official drivers from that RS232 <-> USB
adapter (http://www.ftdichip.com/Drivers/D2XX.htm)
I monitored the USB transfer with wireshark and you can see part of the
compressed output here:
http://pastebin.com/4jf79vGQ
And if you want you can also have a look at the full file:
http://dl.i-am-alive.at/wireshark_full.txt
Correct me if I'm wrong:
What that tells me is that my endpoint adress is either 0x82 or 0x01.
The length is most of the time 64. So is assume that this is my "nrByteRead"
Can someone look at the logs and tell me if I'm right or wrong? I think
I may still use the wrong "bConfigurationValue"..
Thanks in advance

Have you monitored a USB transfer with the scale using its original
driver? I suggest the 'usbmon' kernel module. Use Wine or a VM if it's
a windows-only app.

Hello,
I'mright now trying to get pyUSB to read from my usb-scale but i'm
running into some issues there.
My python code: http://paste.pound-python.org/show/10095/
and my output: http://paste.pound-python.org/show/10096/
As you can see, it just stops at line 49 of the code.
In the Tutorial
(http://pyusb.sourceforge.net/docs/1.0/tutorial.html#how-am-i-supposed-to-work)
it says you first have to issue a "set_configuration" request.
I tried all three different methods (line 31, line 33 and lines 35
to 37) but it always tells me:
http://paste.pound-python.org/show/10097/
Any idea what I'm doing wrong, or how I can establish a successful
connection?
Thanks in advance
David
