Looks like the new device detection code causes problems with the PRS500 on windows. I no longer have mine to test with, so could you do the following:
Install python 2.5 from
http://python.org/ftp/python/2.5.1/python-2.5.1.msi
Then install the (python win32 extensions) from
https://sourceforge.net/project/down...5.exe&12384980
Finally download the attached file to some directory on your computer.
Now open a terminal ad type the following command to start python
Code:
c:\Python25\python.exe
Now at the python prompt, with your PRS500 connected, type the following lines, line by line
Code:
import wmi, pythoncom
pythoncom.CoInitialize()
w = wmi.WMI()
devices = [c.Dependent.DeviceID.upper() for c in w.USBControllerDevice()]
for d in devices: print d
Sorry for the runaround
And post the output of the print statement
