The kernel configuration was the trick!

[Clemens Gruber]

Hello,

The Device Node /dev/ttyUSB0 wasn't there until we enabled the option 
"CONFIG_USB_SERIAL_FTDI_SIO" as a module in the kernel.
Because there was no information about this in the documentation, i 
suggest to add it to the wiki.

If we do a "librfid-tool -s" to search for tags, we always see a bunch 
of error messages on the debug interface:
WRAP DURING APPEND
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! 
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! 
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIT
WRAP DURING APPEND
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! 
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIL! 
NO_RCTX_AVAIL! NO_RCTX_AVAIL! NO_RCTX_AVAIT
....

We don't understand what's going wrong.
I hope somebody can help us..

best regards,
Clemens Gruber
