Qt Android with FTDI - which driver to use ?

[phenoboy]

I want to FTDI dirver work in non-root phone. Is only possiblity to use newer D2XX .jar library and make native calls from Qt to use that ?

Here are the drivers: http://www.ftdichip.com/Drivers/D2XX.htm

I tried native drivers ( http://www.ftdichip.com/Drivers/D2XX/Linux/libftd2xx-arm-v5-sf-1.4.6.tgz ) for ARMV5 but seems they don't work because library is built in wrong hash style and is incompatible with Android host system. Also I read that you need to be root user for this native driver to work.
