Hello list,

I got an "eKey RS485 to USB converter" and they seem to work with an FTDI
chipset (FT232BL). The USB vendor is FTDI (0x403) but the product ID is
somewhat unusual: 0xCB08.

I tried to quick hack the uftdi driver, and the probing works. But any
read attempts on the created /dev/cuaU0 or /dev/ttyU0 fail with EAGAIN.

Any suggestions or hints on how to get this TOCAnet eKey converter
working?

Regards,
Florian Stinglmayr
