I then delete pyusb-0.4.2 and reinstall the svn version of pyusb. The
following program works fine.

#!/usr/bin/env python

import usb.core
import usb.backend.libusb01
b = usb.backend.libusb01.get_backend()
assert b is not None
#import usb.legacy

def opendevice(idVendor, idProduct):
        devices=[]

        for b in usb.busses():
                for d in b.devices:
                        if d.idVendor==idVendor and d.idProduct==idProduct:
                                devices.append(d)

        if len(devices)==1:
                device=devices[0]
                return device

        elif not devices:
                raise "Device not found"
        else:
                raise "More than one device found"

if __name__=="__main__":

        device=opendevice(0x04d8, 0x0033)
        packet_len=64

        dh=device.open()

        dh.setConfiguration(1)
        print "set Configuration 1"
        dh.claimInterface(0)
        print "claim Interface 0"
        #dh.setAltInterface(0)

        # To get firmware version number
        print "Sending version command by USB interrupt write"
        dh.interruptWrite(0x01,"v",1000)
        print "Getting version command by USB interrupt write"
        r=dh.interruptRead(0x81,3,1000)
        print r

[mc...@myfreebsd ~/Desktop/build/pyusb/tests]$ python testpk2_1.py
set Configuration 1
claim Interface 0
Sending version command by USB interrupt write
Getting version command by USB interrupt write
array('B', [2, 32, 0])

But unfortunately it is still using libusb10 backend.
