    Hello all, i have a problem with a smartcard reader on my udoo, using debian armhf. I use to compile a program (oscam) that use libusb to talk with this ftdi card reader, but when I start oscam I get this error (could not read reader-convention). Could it be a library error?

    I had my own adventures trying to access the ftdi driver. I finally made progress when I ran

    sudo modprobe -r ftdi_sio

    I thought libusb would have more control over the kernel driver though.
