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?
