Build failure for fx2pipe on LMDE

Hi, I'm getting a weird compiler error building this:

Making all in usb_io

My system is:

Thanks! Steve

Can you check what version(s) of libusb you have installed

dpkg -i | grep libusb

If I remember correctly, fx2pipe needs libusb0,1 and won't compile/work against libusb1.0.

For reference, there was an eevblog thread about this: https://www.eevblog.com/forum/programming/updating-fx2pipe-to-work-with-libusb-1-0/

Might also be worth you trying cannelloni: https://github.com/jhol/cannelloni

I will have a look at cannelloni. Thanks!
