[Libusb-win32-devel] Segmentation fault in usb_submit_async

[Christian Z. <za...@tr...>]

Hi,

I need some advice on debugging libusb-win32. I get a segmentation fault
in usb_submit_async(). There isn't too much code in that function, any
hints on what the problem could be or how I can approach this?
Also, is it likely that this is a bug outside of libusb, with wrong
parameters or maybe the specific usb driver?

I'm using libusb-win32. 0.1.12.1 filter and ObexFTP to access my mobile
phone (download at http://triq.net/obexftp/obex-win32.zip )

This is from gdb:
