We've been using EZ-USB for many years to build applications for our products without any problem. Recently we've switched to Windows 7 (32-bit), and even after installing CYUSB to replace EZ-USB, are having intermittent problems running hex2bix under windows 7.
When I run HEX2BIX from a command prompt it fails (as reported by windows) about 25% of the time (once or twice out of five or six tries). Has anyone else seen this behavior? I've tried changing the program's compatibility mode, but this causes Windows to ask if it's OK to let the program make changes to the system every time it runs (a typical build compiles a dozen modules, so that's a PIA).
You can find the source of Hex2bix in C:\Cypress\USB\Util\Hex2Bix. Try compiling it with the later versions of visual studio, say VS2008. I'll check if i'm able to catch hold of a Win7 machine and figure out what this issue is all about.
