Libprs500 doesn't detect reader
I installed Libprs500 0.4.24 today and elected to also install the device drivers. I uninstalled the Sony drivers as directed by the installer. Now when I call up libprs500.exe it does not seem to recognize my reader. The only icon in the window is "Library", and the "Send to Device" button is greyed out. My reader is connected and I have the usb icon on the reader itself to show the computer recognizes it. How do I get Librs500 to see it? My reader is the PRS500.
