Just set the environment variable USB_DEBUG to 255 and you will see an error message. But the binary interface of libusb has not been design to report such errors, and changing it now will break a lot of software. You will have to wait for the next generation of libusb that is currently being developed.
Fine by me, so long as there's a fix sooner or later. I'm writing to point out the need for a fix, so that it does not get overlooked in the next iteration. I searched this list as so far as I know it's not been brought up. (And I've gotten some small encouragement from the #debian irc channel to report this as a problem. It's bad when you've been telling people to lsusb and then you find out that the results may or may not be accurate.) Does anyone think that the described behavior is desirable? If not then that's about as much assurance as I can hope for that somebody will do something to fix the problem. OTOH if it's not going to get fixed I'd like to know that too. This is the point where it's polite to thank folks for all the work they've done. So thank you. Regards, Karl <[EMAIL PROTECTED]> Free Software: "You don't pay back, you pay forward." -- Robert A.
