I have this C++ dll where i created a wrapper with PInvoker. This small app is working great on my development pc with windows 7 64 bit. But soon as i try to work the release on a xp machine and when a specific action is happening it throws an error that the device is not ready. The dll is managing a serial device, where in all other actions seems to work fine.
I guess there is something installed or a library i should need on the xp machine. I just cant find what this could be to fix this problem.
Please any thoughts would be great.
Thank you.
