Hi,
Seems that your card is a "serial" device and not usb?

Hi,
I'm trying to improve the times in a code. In the 99% of the times, when
youdoes the "discover" process (to check if your device is connected) you make:
list = []for bus in usb.busses():for dev in bus.devices:if
dev.idVendor == SOME_VENDOR and dev.idProduct == SOME_PRODUCT:
).
This makes only difference for fast transfers and large data packages.
For me it makes a difference when transfer rate is >5MB/s.
Best Regards,
Tomek

Classic problems of permissions. Check your UDEV rule.Do in a console:

Hi,
The package python-usb of wheezy must be 0.4...I recommend download the 1.0
version of PyUSB:

Unzip the file.Open a terminal go to the folder "pyusb-1.0.0a3"open python:

I think that PyUSB 1.0 must be called "stable" (I use and not have problemsof
the library).
Another problem: only PyUSB 0.4 is packaged. Who is the packager?
