hai sir how to communicate the usb thumb sensor with arduino.....

when am connecting thumb sensor with my system.. i got following results..

here am getting two types of data transfers

  1. bulk transfer
  2. interrupt transfer...

You'll have to find a driver for that USB class, for e.g. a Leonardo or other Arduino with USB master capabilities. Most probably you'll have to read more about USB device types and drivers.

but iam getting

bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00

so how to solve this problem

5

Unless the USB specs state differently, I interpret the 0x00 as the device saying "I don't want to reveal anything" :frowning:

6

is there any solution that i can get the "class", "sub class" protocol addresses...

7

i got class, sub class and protocol as 0x00..

is there any other possibility to communicate with arduino....

8

An Arduino can communicate in many ways, but the thumb sensor most probably can't.

9

how to get transfer in function as "0" in usb.....

10

how to communicate thumb scanner with arduino.....
