Re: [Libusb-win32-devel] application works with older libusb-win32 but not with version 0.1.12.1

Well, since the application on the controller is not written by me I can't
give you the code. But I can post what TestLibUsb gives me:
wTotalLength: 46
bNumInterfaces: 1
bConfigurationValue: 0
iConfiguration: 0
bmAttributes: 80h
MaxPower: 50
bInterfaceNumber: 0
bAlternateSetting: 0
bNumEndpoints: 4
bInterfaceClass: 255
bInterfaceSubClass: 0
bInterfaceProtocol: 0
iInterface: 0
bEndpointAddress: 01h
bmAttributes: 02h
wMaxPacketSize: 64
bInterval: 0
bRefresh: 0
bSynchAddress: 0
bEndpointAddress: 81h
bmAttributes: 02h
wMaxPacketSize: 64
bInterval: 0
bRefresh: 0
bSynchAddress: 0
bEndpointAddress: 02h
bmAttributes: 02h
wMaxPacketSize: 64
bInterval: 0
bRefresh: 0
bSynchAddress: 0
bEndpointAddress: 82h
bmAttributes: 02h
wMaxPacketSize: 64
bInterval: 0
bRefresh: 0
bSynchAddress: 0
As you can see, the bConfigurationValue is 0, not 1. Is that the problem?
And if it is, why does it work with the older version of the lib? Do I have
to change the value to 1 (which might be a problem as I can't flash the
controller...)?
Best regards
