Description Greg Kroah-Hartman 2006-02-15 12:15:14 UTC

Comment 1 Greg Kroah-Hartman 2006-02-15 13:36:38 UTC

Ok, I've added everyone who has reported this kind of problem with the
usb stack to this bug.  If you don't want to be on it, please feel free
to remove yourself.

The problem is that the error:
  device not accepting address XX, error -71
is happening for some device in your system, on the latest kernel version.

But unfortunatly, it's not easily reproducable for anyone in the Linux
USB developer group.  None of my devices or systems cause this error.

So, any help in trying to debug this would be greatly appreciated.

I know Alan has a suggested patch that might help people out, if he could
attach it and people could try it out, that would be very helpful.

Also, if people use git, could you try to use 'git bisect' to determine
exactly what change caused this to happen?  I think it was working fine for
2.6.13 or maybe 2.6.14, but 2.6.15 and later has the problem reported for it.

Increase the reset recovery delay time

Here's the patch Greg mentioned.  It helped one user with an iPod; I'm sure it
won't help everybody.  In that case the problem was in the iPod, but the
general problem appears to lie in the host controller hardware.

Comment 4 Alan Stern 2006-02-15 14:34:54 UTC

A related bug report is #5777.  Len Brown found that the internal hub in his
laptop's docking station wouldn't accept an address until he reloaded ehci-hcd.
 However, he also found that using a different .config fixed it.  Nobody has
tried to duplicate his results or interpolate between the two .configs to see if
the problem can be traced to a single item.

Comment 5 Solomon Peachy 2006-03-09 13:45:41 UTC

I have this problem on a bus-powered High-speed USB drive.  If I plug it into
the onboard OHCI controller, it works.  If I plug it into an add-in ALI
OHCI/EHCI card, I get the -71 error.  I haven't tried unloading the EHCI
component.  

This machine is a Serverworks Dual P3 box and is running the Fedora
2.6.15-1.1833_FC4smp kernel; the USB disk is for backup purposes.

Due to the production nature of the machine I can't take it down for random tests.

Comment 6 Solomon Peachy 2006-03-31 08:27:23 UTC

As a FYI, Using Fedora's 2.6.16-1.2069_FC4 kernel (based on 2.6.16.1) I'm still
seeing this.  If I remove ehci_hcd, the device comes up just fine, albeit at
full (ohci) speed.  If I unload/reload ehci_hcd, the device still malfunctions:

At this point it shows up in 'lsusb' but is otherwise dead.

There are a few other load/plug/etc permutations I can try.

Comment 7 Alan Stern 2006-03-31 08:40:30 UTC

Solomon, your problem may simply be caused by a poor USB connection.  That is,
the cable may work okay at full speed but not at high speed.  Check the USB
cable and connections.  It could also be due to a hardware problem in the disk
drive's USB interface.

Sometimes there are just some small incompatibilities between pieces of
hardware.  I've got a USB disk drive and cable that don't work on my home PC. 
Switching any one of the PC, the cable, or the drive is enough to get things
working again.

experimental 2.6.17-rc3 SET_ADDRESS patch

Worth maybe trying this patch.	When SET_ADDRESS fails, the state of the
device is actually indeterminate.  Linux currently assumes the operation
actually succeeded, which is rather optimistic.  This patch makes a more
pessimistic assumption.

Comment 9 David Brownell 2006-06-13 12:42:22 UTC

PING.  Have you actually tried the patch?  It's been sitting 
there for over a month now waiting for you ...

Comment 10 Greg Oliver 2006-07-08 12:58:45 UTC

I have seen this probolem with my Motorola Phone since 2.6.13 I believe.  I just
compiled 2.6.17-rc3 with debug turned on for USB, and here is th eoutput if it
helps.  udev loaded cdc_acm as expected, and the phone charged for ~4 seconds
and then quit.  Better than 2.6.16 was doing.  This was the only time it has
worked at all - even for 4 seconds since it has happened after the fresh reboot.
 removing the modules and reloading them have no affect either.

Same behavior with two different machines.

Sounds like it could be a wiring problem on the gumstix, or something of that sort.

I'm seeing this problem with my Scanjet 5300C on Ubuntu 7.04 with 2.6.20-16.

I'll try the patch from David Brownell, and let people know if this is works.

This may take a while, as I've never built a kernel under Ubuntu before :)

Comment 15 Phil Lello 2007-10-16 05:06:29 UTC

Nope, the David's patch doesn't fix my issue.

There's nothing new in the logs that I can find, but if i boot in Ubuntu's 'recovery mode', I get extra "device not accepting address X, error -71" messages echo'd to console.

lsusb doesn't show the scanner, but is frequently slow... I guess this is because it has to wait for the bus reset to finish.

e.g. :
phil@Ubuntu:~/kernel$ /usr/bin/time --format="%E" lsusb
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 002: ID 046d:08f6 Logitech, Inc.

I've not done any kernel debugging before, so please provide hints on anything else useful I can do.

Comment 16 Phil Lello 2007-10-17 06:16:00 UTC

Hmm... just read my own last update and spotted that the scanner actually got picked up once, then disappeared.

I've downloaded some USB docs, and will go through this... as a pure, ill-educated guess, it could be that the SET_ADDRESS is being timed out by the stack, then takes effect on the device, and then getting clobbered by the hub reset.

Comment 17 Phil Lello 2007-10-18 17:23:36 UTC

The SET_ADDRESS problem is fixed in the 2.6.22 kernel.

I can get a preview scan in sane fine, but for some reason it a full scan fails.

This may well be a problem in either sane or libusb, and even if its a usb-kernel bug, it is unlikely to be related to the SET_ADDRESS problem.

Also see http://qa.mandriva.com/show_bug.cgi?id=26728#c41, which includes apparently related information (talking specifically about HP5300C/HP5370C scanners with apparently broken USB protocol) and which includes a patch.
