Hi guys,
I have the following problem. When I try to connect to a USB to serial Converter the Rpi freezes. The library I'm using is nmodbus. Has someone been able to connect with a Modbus rtu device and if yes using what library?

After some tests I found out that the Rpi freezes when you try to connect to the USB converter.

Yes, I am using libmodbus-3.0.3 with raspbian and FTDI USB-RS485 Cable.
It works fine, but there is something wrong with the USB driver that hangs thi pi. You can read more about this on http://www.raspberrypi.org/phpBB3/viewtopic.php?t=8010&p=210013

Edit: The problem doesn't seem to be the power consumption of the converter, since it only draws 20 to 25 mA from the USB.
