Fabio: Hmm yes those do look the same, but we haven't got Seth (original reporter) logs for it so we don't know if it was the problem he hit; so please file a separate kernel bug for that, and add a comment here stating the bug number. (I suspect most of the problems here are kernel bugs of one type or another - whether they're all the same bug is a different question).

[Bug 570049] Re: lsusb hangs forever
Hi Dave, what made me file my logs here is that both the symptom (lsusb hanging) and what looks like the underlying cause are both the same.

Hi, I've been experiencing the same issue on my Ubuntu 11.04 or 12.04 installations. Usb devices suddenly stops working after I plug/unplug some of them. I have a USB-Serial converte and an external SD-card reader and both seem to trigger the problem Only "workaround" is to reboot the system (which is not a solution, obviously). As it looks like from dmesg, the crash of khubd is at the root of the problem, and being a kernel thread can't be "restarted" other than rebooting Looks like a common problem, across different distributions... thanks Fabio ** Attachment added: "several logs" https://bugs.launchpad.net/ubuntu/+source/usbutils/+bug/570049/+attachment/3394401/+files/lsusb_hang.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/570049 Title: lsusb hangs forever To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usbutils/+bug/570049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 570049] Re: lsusb hangs forever
Hi Dave, You're right about ndiswrapper. I uninstalled it, rebooted and ran lsusb with no trouble (it also recognized my Netgear USB device). I don't like using ndiswrapper, so I looked for a different solution for my adapter, but unfortunately none of the open source drivers seem to work. I'll log a bug against ndis as suggested.

[Bug 570049] Re: lsusb hangs forever
OK, so I think your case may be different from some of the others that have
attached dmesg;
yours shows an oops in ndiswrapper driver wrapper that loads windows wireless
drivers; can you open
a separate bug against the 'linux' package with a title something like
'oops in ndiswrapper on lsusb' and include the same tar of debug stuff and a
copy of this comment.
I don't know your particular hardware, but if there is an open driver that
doesn't need ndiswrapper it's worth trying it.
the strace in your case finishes with:

472 open("/dev/bus/usb/001/002", O_RDWR) = 4

to the USB 2.0 controller), so I recovered the traces requested by Dave, which
I hope can be helpful (attached).
The end of the strace looks like this, and the /dev/bus/usb/001/001
corresponds to the USB 2.0 controller itself, not the devices:
open("/dev/bus/usb/001", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC)
= 3
getdents(3, /* 5 entries */, 32768) = 80
open("/dev/bus/usb/001/007", O_RDWR)= 4
ioctl(4, USBDEVFS_CONNECTINFO, 0xbf80d128) = 0
read(4, "\22\1\0\2\0\...@x\20\20\t\6\1\1\2\3\1", 18) = 18
read(4, "\t\2 \0\1\1\0\300", 8) = 8
read(4, "\1\t\4\0\0\2\10\6P\0\7\5\201\2\0\2\0\7\5\2\2\0\2\0", 24) = 24
close(4)= 0
open("/dev/bus/usb/001/006", O_RDWR)= -1 ENODEV (No such device)
open("/dev/bus/usb/001/006", O_RDONLY) = -1 ENODEV (No such device)
open("/dev/bus/usb/001/001", O_RDWR)= 4
ioctl(4, USBDEVFS_CONNECTINFO
The 'lsusb' process is left in the D+ state and a reboot is required to clear:
root 2004 0.0 0.0 1992 660 pts/0S+ 01:14 0:00 strace lsusb
root 2005 0.0 0.1 2476 1136 pts/0D+ 01:14 0:00 lsusb
dmesg shows a USB disconnect, followed by the hung task timeout + Call Trace:
[ 1221.678187] usb 1-6: USB disconnect, address 6
[ 1440.200059] INFO: task khubd:22 blocked for more than 120 seconds.
Earlier the same device gets bounced after the 1st disconnect:
[ 825.352643] usb 1-6: USB disconnect, address 5
[ 825.652071] scsi 6:0:0:0: rejecting I/O to dead device
[ 825.652092] ready
[ 825.652107] scsi 6:0:0:0: rejecting I/O to dead device
Hopefully tells us more about this problem.

[Bug 570049] Re: lsusb hangs forever
Hi James,
Your strace is interesting, the very bottom of it is :
open("/dev/bus/usb/002/002", O_RDWR)= -1 EACCES (Permission denied)
open("/dev/bus/usb/002/002", O_RDONLY) = -1 ENODEV (No such device)
open("/dev/bus/usb/002/001", O_RDWR)= -1 EACCES (Permission denied)
open("/dev/bus/usb/002/001", O_RDONLY) = 4
ioctl(4, USBDEVFS_CONNECTINFO, 0x700b5610) = -1 EPERM (Operation not
permitted)
read(4,
So, it doesn't like something about /dev/bus/usb/002/001 - but we don't
know what that is.
So, can you repeat the strace, then look at the bottom few lines for the last
name past to open( - if it's /dev/bus/usb/002/001 again
can you then include the output from:
udevadm info --query=all --name=/dev/bus/usb/002/001
which should hopefully tell us what it is and which driver it is using.
Dave

I am having the same problem of lsusb hanging, and disk utility shows no usb devices. (and my USB access is flaky, although my logitech wireless mx5500 works fine, most of the time).

[Bug 570049] Re: lsusb hangs forever
I am running i386 Ubuntu 10.04 with this error. Neither lsusb nor ndiswrapper will run without freezing up and staying frozen. This also effects the ability to System -> Administration -> System Testing, as this will freeze and never continue. I tried to install a Compaq W200 card and this might have been a side-effect of this operation (https://help.ubuntu.com/community/WifiDocs/Device/CompaqW200). Also, the instructions to get the W200 failed for me.

[Bug 570049] Re: lsusb hangs forever
I have the same problem on several machines since debian sarge and also on every ubuntu-version i used. Sometimes lsusb works with no problem and then on the same machine it hangs without any output and I can only kill it from a other terminal via killall lsusb, after reboot of the machine everything works again. I found any log message until now. -- lsusb hangs forever https://bugs.launchpad.net/bugs/570049 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 570049] Re: lsusb hangs forever
I suggest including: 1) Output of lspci -v 2) Output of dmesg 3) The result of strace lsusb 4) The output of find /sys/bus/usb Hopefully some of those might show what's odd.
