To begin with, your former code can be summed up to this (with latest
git PyUSB):
import usb.core
import usb.util
import sys
VENDOR_ID = 0x24e9
PRODUCT_ID = 0x0824
device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)
if device is None:
sys.exit("Could not find Id System Barcode Reader.")
else:
print 'Device detected'
device.set_configuration()
device.write(0x01, [0x01]) ---> you probably meant [0x01] or '\x01'
instead of '0x01'
print device.read(0x82, 64, 1000)
If you are still getting a read timeout, that is probably because the
0x01 command means nothing to the device.
