I've put it here: http://mbox.bz/pub/lsusb-v-before.txt [17k, before timeout] http://mbox.bz/pub/lsusb-v-after.txt [16k, after timeout] After the device went bad lsusb announces protocol errors while querying it. That's not surprising but I put the after- output there too, for completeness. > And the rest of the debug log ... with initialization dump > for the EHCI controller, at "00:0e.3" ?

The > diagnostic with "descriptor data left" seems to be a new clue. You are right. I overlooked it before but it really is a GeneSys. Do you happen know an usb2->ide bridge (sold in a 2.5" external hdd-case?) that definately works in linux 2.4?

I just attacked the drive again, with the patch applied and USB Mass Storage debug verbosity enabled. Here is the relevant parts from the log of that session: http://mbox.bz/pub/kern_ehci-debug.log [2.2M] or http://mbox.bz/pub/kern_ehci-debug.log.bz2 [ 18k] The full log was 103M. I cut out large chunks of the repeated error messages to bring it down to a reasonable size. The cut out parts were replaced with a few hundred hash-lines. So you can skip to the next part of the log by searching for "####". The additional debug messages reveal that the device behaves just the way you described (if i parse them right that is). It seems to block in the middle of transfer and times out. > One person had better luck after applying a patch that slowed > down EHCI on an NForce2 southbridge ... the fact that it even > mattered is in indication of problems in the GeneSys device. I assume the wintendo drivers use a similar hack to make the thing work then. What really pi**es me off right now is that the case has the USB2.0-logo printed on it.

Unfornationally I cannot switch to 2.6 at this time[1] but I will try it once soon, just to see if the bridge works in there. Thanks for your advice so far. Best regards Moe [1] I Need VMWare and I doubt the kernel-modules will work in 2.6 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
