what is the preferd module to use for interfacing to a USB device

Hi Folks,
I need to interface to a USB device to do read/write (send some text
commands and receive some text back from the device, just like the
traditional RS232). I have looked CPAN there are several modules but seem to
be very new. Any idea what is the preferred way to do this. Do you have any
code that can help start.

Regards,
