Hi David,
i've tried your suggestion and now it works.
I'am sure, it didn't work last time i've tried that way. But now, I'am fine.
Thanks.

One option I resorted to is using Qemu's emulated USB serial device and
connecting it to the USB serial device host side. The stack then looks like:
.---------------------.
| VM |
| |
| /dev/ttyUSB0 |
|---------------------|
| Qemu - serial device|
'---------------------'
|
.---------------------.
| Host: /dev/ttyUSB0 |
'---------------------'
|
.---------------------.
| USB serial port |++++++++<-- character stream -->++++++++
'---------------------'
A hack, but it works. :-)
