Windows 7 compatibility

Post by Wizzboy » Sun May 22, 2011 3:06 am

Hi,

I've playing with V-USB all day. I've converted a ATmega164P + FTDI FT232RL board into a ATmega164P with USB (poped the FTDI chip out and wired it up).

I've configured the whole thing and it does respond correctly on Windows XP, but on my Win7 laptop, windows cannot recognized the device as HID. Is their any know problems with windows 7?

Thanks for any info.

It might more be a hardware problem in combination with your laptop. V-USB isn't 100% up to USB spec, but it works in most cases. I had some troubles with my laptop, I made the cables a bit shorter which resolved the problem in my case.

If the program has not run on anything since Windows 98, it will almost definitely NOT work on Windows 7. Windows 7 has better backward compatibility than previous versions of windows, but a piece of software over a decade old will surely have problems no matter what you do.
