How to install a driver of my USB-A to Serial Cable

Hi Gurus of Unix
Recently I install a OpenSolaris in My HP 530
In this moment want to install a USB-A to Serial Cable. Any guru can send a Link where I can use how reference.

I want to configure a Router and my PC don't have any serial Port.
My LapTOP only has USB ports. In this case I buy a Adaptor from USB to Serial, but the drives is only for windows.

Any Guru that can help me

plugin the usb adapter and watch/post the output (last lines) of "dmesg". maybe solaris knows the adapter... also try a "reconfigure" boot with the device attached.

also have a look here:
