[solved] YUN serial USB to UART via CP2012: how?

I got wifi setup and ssh to device.
$> opkg update
$> opkg install kmod-usb-serial-ftdi
$> dmesg

$> ls /dev/tty*

tty ttyATH0 ttyS0 ttyS1 ttyS10 ttyS11 ttyS12 ttyS13 ttyS14 ttyS15 ttyS2 ttyS3 ttyS4 ttyS5 ttyS6 ttyS7 ttyS8 ttyS9

where is /dev/ttyUSB0? I can't find a kmod-usb-serial-cp201x package, either.

Please: What do I do?

…huh. after a second opkg update it appeared in opkg list. Wierd. Thank you!
