[Libusb-win32-devel] Problems with usb_set_configuration

[John E. <jei...@mw...>]

Hi,

I have just started building a driver for 
my custom USB device. I started by using the Windows usbser.sys as 
a CDC driver. This worked well for my board.

I then downloaded the libusb binary driver (not the filter driver)
and used that to start my USB application. I am using the free 
Borland BCC 5.5.1 compiler. The code compiles and runs.

Upon detecting my device I issue a usb_set_configuration() to select 
configuration 1. Then I claim interface 1 which is the data interface for
my CDC implementation.

The SET_CONFIGURATION command is never sent to my device. This 
means that the device always stays in the address stat and never goes into 
the configured state.

What am I doing wrong here ?
