[SailfishDevel] No QSerialPort

[Wim de Vries]

Thank you guys.
Indeed devel-su works.
I have attached the devices, but the first problem is that the 
connection does not supply power (the devices stay dead).
As far as I know, a usb connection should always have power, but it is a 
bit beyond my kowledge. Do I need another plug?

On other linux/MeeGo systems there was always power...
and dmesg would give:

Use Qserialport on ttyUSB0 and ready you are.

Nothing of this the dmesg of Jolla, though :-(
