Hey,
I'm sure the error happens somewhere inside libftdi or more probably libusb.
The function does not return, so I'm quite sure it's not my Program that's
faulty... MAybe I really need to dig into libusb a bit.
I'm using libusb 0.1. Isn't that the only one supported by libftdi?
Thanks for the help
Tim
