[Libusb-win32-devel] Reg libusbk error code 4c7h

[Cilambarasan R. (RBEI/EAC1) <Cil...@in...>]

Hi,
  I am using the libusbk. My usb device is cdc type uses bulk transfer.  I tried to read my device using the EP_Address 0x81 with xfer-async-loop example.
  Getting the following error. Libusbk version 3.0.7 running in Windows 7 OS.

Error code obtained as following. I browsed to find the similar issue reported https://github.com/mcuee/libusbk/issues/2  in 3.0.4. But I find this happens in the 3.0.7 as well.


Failed getting i/o results. ErrorCode: 000004C7h
