Re:
I have tried the library in your link. At the beginning, I had a difficulty because the compiler couldn't find the file "JclUnicode.res" in the folder: "jcl\jcl\source\common". There was the file "JclUnicode.rc" instead. So I used the MS-DOS prompt to convert it to *.res with the command "BRCC32 file.rc".
Then the program ran properly except that it doesn't display the vendor name and the product name, but for the VID and the PID it's okay.
Do you have an idea of the problem?
