[libusb] My problem with URB_FUNCTION_GET_DESCRIPTOR_FROM_ENDPOINT

[toannt <toa...@gm...>]

Hi all,
I'm writing a sample application to simulate USB Transfers to USB Mini
Pocket Airpen.
I'm using the URBs capturing by USBLyzer application and libusb 1.0.9.
My problem is that: All URBs are simulated successfully except for 1 Control
Transfer URB as below:
The result of USBLyzer on Windows:

/Sent package:
USBPDO-1 - usbehci:
 Request: get descriptor from endpoint. (code 0x24 on Windows).
 Request Details: report.
 I/O: in.
 URB details:
  Reserved 1: 0000h.
  Index: 00h.
  Descriptor type: 22h.
  LanguageId: 0001h.
  Reserved 2: 0000h.
 Length: 64h.

Respond package:
Usbehci - USBPDO-1:
 URB details:
  Setup package:
   bmRequestType: 82h
   bRequest: 06h.
   wValue: 2200h.
   wIndex: 0001h.
   wLength: 0064h.
return actual length: 24h./

I've tried libusb_control_transfer(mHdlDevice, 0x82, 0x06, 0x2200, 0x0001,
testbuff, 0x64, 0);
The result is -1 and errno: 2.
please anyone help me to correct my control transfer params in this case.
Thought that bmRequestType x82 and mRequest x06 is not match to standard
CTRL Request.
