There will be a new way to write USB drivers from userspace in a couple months. usbfs is slowly being replaced by a new usb file system, usbfs2. Eventually, user-space USB drivers will just use usbfs2, and libusb won't be needed anymore. usbfs2 will have asynchronous support for bulk, interrupt, and isochronous transfers. It will also represent USB devices as several endpoint files in /dev that drivers can read and write to. The project page for this is http://wiki.cs.pdx.edu/usb/usbfs2.html Sarah Bailey
