[Linux-usb-users] Re: EHCI and external enclosure hangs all test systems

I have been having serious problems trying to get a USB 2.0 host controller working with a external USB IDE enclosure under Linux.

Short version of the story:  don't report such bugs against current
2.4 kernels unless you reproduce them with the patch Greg resubmitted
yesterday to Marcelo for 2.4.20 ... sounded like Marcelo would merge
it this time.

If your problem appears in 2.5.latest, or 2.4.20 with that patch, that'd
seem to be a new problem, not yet reported by anyone.  But a lot of your
symptoms sound exactly like ones that have been fixed by that patch.

I have applied the patch (I assume you are referring to the patch found 
at 
http://www.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-ehci-2.4.20-pre11.patch, 
it seemed to be the only recent patch that is relevant to my problem) to 
a 2.4.20-pre11 kernel tree, but I am still seeing the same problems as 
before.  When reading from the disk, all activity will cease and the 
process hangs.  Any further attempt to access the disk will also hang.   
It may have taken a little longer than before the patch to hang, on 
this test I read ~850 MB before it quit.  
With kernel 2.5.44, sometimes I can access the disk (and eventually hang 
as above) and sometimes I never can access the disk at all (with the 
errors listed below being repeatedly logged).
