What NetBSD version is asrock running ?
On a stock 6.0_STABLE GENERIC of some time ago, it's probed as:

uhub5 at uhub4 port 7: Standard Microsystems product 0x2412, class 9/0, rev 
2.00/b.b2, addr 2
uhub5: single transaction translator
uftdi0 at uhub5 port 1
uftdi0: FTDI BeagleBone/XDS100V2, rev 2.00/7.00, addr 3
ucom0 at uftdi0 portno 1
ucom1 at uftdi0 portno 2

and I can connect to the console with:
cu -l /dev/dtyU1 -s 115200

(console is on the second serial port; I'm not sure what the first one is
for, maybe the jtag ?)
