[Grigor K. <gri...@gm...>]

Hi!

I try to read data from USB Fingerprint reader

I connect wit reader and it work

import sys

import usb.core

import usb.util

 

VENDOR_ID=0x045E

PRODUCT_ID=0x00BD

DATA_SIZE=64

 

device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)

 

 

 

try:

    device.set_configuration()

 

except usb.core.USBError as e:

    sys.exit("Could not set configuration: %s" % str(e))

 

endpoint = device[0][(0,0)][0]

print endpoint

 

data = []

swiped = False

print "Send a code..."

a = 0

while 1:

    try:

        dev = device.read(endpoint.bEndpointAddress, 

                            endpoint.wMaxPacketSize)

        data.append(dev.buffer_info())

        

        if len(data)>2:

            print data[a]

            a = a+1

 

        if not swiped:

            print "Reading..."

        swiped = True

 

    except usb.core.USBError as e:

        if e.args == ('Operation timed out',) and swiped:

            if len(data) < DATA_SIZE:

                swiped = False

                continue

            else:

                break   # we got it!

 

How can get value?
