Hallo,
I tried to run Alexander Morozov's patches against wine-git with libusb and ftd2x devices.
Two remarks: - The files from ftp://ftp.etersoft.ru/pub/people/amorozov/usb/current/ miss lines in configure.ac to trigger the Makefile generation for usbd.sys and usbhub.sys. - The HardwareID in the registry is the end of the Registry key http://msdn.microsoft.com/en-us/library/dd568018.aspx You can use the string itself in the win registry. This helps, if you don't have the devices installed on a windows machine available.
Both dll/drivers pair (libusb0.dll/libusb0.sys and ftd2xx.dll/ftdibus.sys) work an a lot devices and so must scan the bus for matching devices. I didn't get wine with the patches to do anything sensible in that case.
Alexander, could you perhaps have a look (ftd2xx at http://www.ftdichip.com/Drivers/D2XX.htm and libusb-win32 at sourceforge)
Thanks
