I'm developing a USB device, using the microprocessor JM32, and a Windows software for communicating with it, using Visual Basic 2010 and the library SimpleUSB.dll provided by Freescale (I've followed the tutorial "USBJM_Training GUI").
I've no problem under Windows XP SP3 (communication ok, all data bytes sent and received correctly).
Instead under Windows 7 64 bit I've this issue: the driver seems to have been correctly installed (after a little modification to the inf file generated by the tool "WinUSB INF Generator"), but the software isn't able to connect to my device.
The question is: is SimpleUSB.dll compatible with Windows 7 64 bit?
Thanks in advance to anyone who can help me.
