My code:
dev = usb.core.find(idVendor=0x0590, idProduct=0x0028)
    if dev is None:
        print "Device not found"
    else:
        print "Device found"
        if dev.is_kernel_driver_active(0) is True:
            print "but we need to detach kernel driver"
            dev.detach_kernel_driver(0)
            print "claiming device"
            usb.util.claim_interface(dev, 0)
            print "release claimed interface"

        usb.util.release_interface(dev, 0)
        print 'Now reading data'
        #dev.attach_kernel_driver(0)

        dev.set_configuration()

        #dev.write(2,'Hello')
    #dev.write(1,'g')
        #dev.write(2,'VER00',0)

        ret = dev.read(0x81,8,0) # read(size,interface)
        print '::::::::::::::', ret
