Interesting - definitely something I will take a look at. Thank you for the pointer. > Or maybe at least improve the current libusb-0.1.x implemenation > for FreeBSD. Yeah, I was looking at backporting some of the features from libusb CVS HEAD to libusb-0.1 on FreeBSD a while back and improving FreeBSD compatability as well for an application, I work on - but we ended up making FreeBSD specific work-arounds in the application instead. The current stable version of libusb certainly makes a lot to wish for on FreeBSD. > By the way, the latest CVS version of usbutils (lsusb) supports > FreeBSD and it is rather a nice tool. Oh, I haven't looked at this in a while. I'll try to come up with a port for FreeBSD.
