There was a bug a while back, which (so far as I know) has been fixed for some time. Different symptoms. > 1) The ehci module's ref count never changes, even when the Archos is > plugged in and showing up in the device listing. Standard for USB host controller drivers. Makes it possible to rmmod them and swap in a new one without disconnecting every USB device on your system. The module refcount mechanism isn't exactly the right mechanism for anything, as far as I can tell. > 2) If you plug the Archos JB into the USB controller, wait until it > shows up in the device listing, unplug it, wait until it's not in the > device listing and then plug it back in, it will never show up in the > device listing. Somewhere earlier in the 2.4.19 series something seems to have broken some part of the highspeed enumeration process. I'm not quite sure what it is yet (haven't made time to look), I'm suspecting one of the hub driver timeout/debounce changes broke some part of the logic that hands devices from one HCD to another. Does that happen if you only have the EHCI driver loaded, and not the OHCI driver? > 3) The ehci module hangs when you try to unload it (i.e. > `/etc/rc.d/init.d/hotplug restart` or just a plain `rmmod ehci`), if the > Archos has ever been plugged in. Hmm, that's bizarre and new. Try to reproduce it with the EHCI debugging code turned on, and send me the dmesg output when you do the rmmod ... both the working case, and the non-working. - Dave ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek No, I will not fix your computer. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
