I must admit, that /dev/umass2 looks better than /dev/usb0.2, but I don't really care :-) Other than that you will, probably, have to take over maintainership of the libusb port... Maybe, even to the point of bringing its relevant bits and pieces into the src-tree. There is simply too much stuff being written for Linux that uses the libusb API to ignore it... It is bad enough, that we can't have video4linux support :( > Some open problems that needs to be resolved: > > Should we allow parallell access to USB interfaces? Not sure, what you mean. Parallel access between multiple interfaces to the same device (umass and ugen access to the same blackberry), or parallel access between two different user-space processes? > And what about rights management? devfs.conf? -mihelp
