Hi Ian,
Actually the reason I decided to use PyUSB was that I found your work(WeDoMore)
a month ago and decided to start using PyUSB.:)
I have tried to use the WeDoMore class/code but I still have no clue what's
going on and plus I get some errors like :
Traceback (most recent call last):
File "C:\Users\DevTech\workspace\testPyUSB1\src\WeDoTest1.py", line 8, in
<module>
self=WeDoMore.WeDo()
File "C:\Users\DevTech\workspace\testPyUSB1\src\WeDoMore.py", line 19, in
__init__
if self.dev.is_kernel_driver_active(0):
File "C:\Users\DevTech\workspace\testPyUSB1\src\usb\core.py", line 687, in
is_kernel_driver_active
return self._ctx.backend.is_kernel_driver_active(self._ctx.handle,
interface)
File "C:\Users\DevTech\workspace\testPyUSB1\src\usb\backend\__init__.py",
line
355, in is_kernel_driver_active
_not_implemented(self.is_kernel_driver_active)
File "C:\Users\DevTech\workspace\testPyUSB1\src\usb\backend\__init__.py",
line
79, in _not_implemented
raise NotImplementedError(func.__name__)
NotImplementedError: is_kernel_driver_active
It seems that PyUSB have been updated since you have used it so has the scratch
code since the screen shot you had posted of the scratch/squeak and their
WeDoPlugin functions is different from what I was able to see yesterday (now
they only have PrimeOpenPort,PrimeClosePort,PrimeRead and PrimeWrite). I am
just
saying this because I am trying to understand what is going on so maybe I am
able to get the code to work....sigh....
Thanks for putting the library together.....:)
Any comment/thoughts would be greatly appreciated.
Thanks
Safoura
