usb_set_configuration problem in 1.2.3.0

[MarkA]

Hi, hope an expert can help me.  

I used libusb since a long time. Recently i updated from 1.12.0.0. to 1.2.x.x and now to 1.2.3.0
Some devices have a problem with usb_set_configuration.
I get the error :  [set_configuration] could not set config 1: win error: The parameter is incorrect.

This param is 1.

This is the device I use :
DLL version: 1.2.3.0
Driver version: 1.2.2.0

bus/device  idVendor/idProduct
bus-0/\\.\libusb0-0004--0x03eb-0x2104     03EB/2104
- Manufacturer : Elektor
- Product      : AVRISP mk2 (CC2)
- Serial Number: 0000A00128255
  wTotalLength:         32
  bNumInterfaces:       1
  bConfigurationValue:  1
  iConfiguration:       0
  bmAttributes:         80h
  MaxPower:             25
    bInterfaceNumber:   0
    bAlternateSetting:  0
    bNumEndpoints:      2
    bInterfaceClass:    0
    bInterfaceSubClass: 0
    bInterfaceProtocol: 0
    iInterface:         0
      bEndpointAddress: 82h
      bmAttributes:     02h
      wMaxPacketSize:   64
      bInterval:        0
      bRefresh:         0
      bSynchAddress:    0
      bEndpointAddress: 02h
      bmAttributes:     02h
      wMaxPacketSize:   64
      bInterval:        0
      bRefresh:         0
      bSynchAddress:    0

Why does it not work any longer? And why does this device work fine with the original Jungo driver?

best regards
mark

Please quote the original thread. And if you can, try to avoid using
Nabble to post. Thanks.
