Help with configure.ac rule wanted

[Uwe Bonnes]

Hello,

for some special hardware, e.g the STLink from ST Microelectronic for
debugging an programming Arm microprocessors, I have translation dlls that
translates the hardware access to libusb calls. To detect libusb, until
recently I added the libusb detection code from
ftp://ftp.etersoft.ru/pub/people/amorozov/usb/
However recenty Alexandre did some work around the configuration area and
things no longer work.

I would appreciate if anybody can help me with coming up with a libusb
detection rule for wine.

Thanks
