Hi, I have not seen that issue before with Xsane. I know that sometimes people report that a window is tiny with nothing in it. I think that is usually related to a corrupted configuration file.
Yeah, I've heard about the libusb issue. I believe Brother even say something about it in the driver instructions now. Xsane is well overdue a release and it is something that I am working on in the background.
