I'm having some kind of trouble with USB-stalls on two devices: * Canon DR1100C scanner (ugen) Easiest to provoke, because it fails right out of the gate and stalls long before any scanning takes place. * GreaseWeazle (umodem) Provoke by doing anything in the browser while a floppy is being read. In both cases my reading of usbdump output is that the trouble starts with a STALL. Who can give me some pointers to how I can debug this further ? PS: These are not new problems, but they have only now bubbled up near the top of my TODO list. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
