SimpleUSB & Windows 7

MSe — Thu, 10 Mar 2011 18:26:19 GMT

Hello,

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.

Above INF file is fine.

SimpleUSB.dll refers to FSLwinusb.dll, a simple WinUSB wrapper DLL made by Freescale for ColdFire MCF522xx. SimpleUSB.dll is a .NET DLL for Any CPU, but FSLwinusb.dll is an unmanaged 32bit DLL.

1) Build your application for x86 platform, instead of Any CPU (Project > Property > Build: Platform target)

2) Place your application with these DLLs into a folder under C:\Program Files(x86) of Win7 x64.
