RE: [Libusb-win32-devel] Re: set_configuration problems

[Dan E. <Dan...@ne...>]

You should only be trying to set the configuration using
usb_set_configuration, doing using usb_control_msg could potentially
bypass the USB stack and cause problems.

It works for me, tested on XP-SP2 with a keyboard and a mouse.

[Libusb-win32-devel] Re: Re: set_configuration problems

[Fouzi B. <fou...@tr...>]

Hi Stephan,

It works for me too now (set_configuration), the problem happened last=20
time because I did not install correctly the new snapshot.
But now, I can't send a bulk message: (LIBUSB_DLL: error:=20
usb_submit_async: submitting request failed, win error: Param=DEtre=20
incorrect).
With the last release of the libusb-win32, the bulk messages works if=20
the set_configuration succeeded, do you have any idea of the reason of=20
that ?

Thank you for your helping !
