Bugzilla – Bug 105585
External USB or Firewire harddisks are still not handled to be usable
Last modified: 2006-02-28 12:29:28 UTC
Bug description at the end. Since introducing subfs the handling of external harddrives has not been improved. Nevertheless the amount of such devices is rapidly growing. Please consider the following: After hardwaredetection has found the new device, ask the user, wheter - he wants to use the device with subfs (suitable for FAT-Disks) - he wants to use the device without subfs (needed for maximum speed and every Linux Filesystem (recommended). In the second case, make usual fstab-entries for the disk, so that it get's not mountet automatically, but is mountable by the user. Bug in Beta2: once an external device gets unmountet, it cannot be remountet again. I opened a 150 GB USB-disk, browsed it and left the window open. When I clicked on a directory 5 minutes later, Konqueror told me, that there is no such device.
Changing Hardware to all, as this is not HW-specific.
Who unmounted the device? The system only umount the device if you remove it or of you unmount it manually. I can't reproduce a umount without user umount. This is the correct behavior for me If _you_ unmount the device you can't access this anymore. I don't understand the problem. If you have a problem with the kde behavior, this is a KDE bug
External devices are mountet on demand by subfs. Of course they are not unmountet, but if you don't use the device, then the system doesn't use it. (e.g df -h does not show up the device) If you change to the directory with cd /media/usbdisk, the disk is activated again. The problem is, that after 5-1o Minutes of inactivity cd /media/usbdisk does nothing. Once the USB-disk get's inactive, you cannot access it anymore. I hope the problem is now clear. Nevertheless it makes less problems on console then within Konqueror.
Created attachment 46853 [details] Log detail, where the USB-disk "gets lost" This appers randomly after 5-10 minutes. If I mount the disk by hand, there are no connection problems.

I have also problems with my Trekstore external 120 GByte USB harddisk. Before SUSE 9.3 I think it worked without any problems. Then with SUSE 9.3 or so the problems started. The cause is the ehci_hcd.ko kernel module. I don't know what you did but I can only use my USB disk with USB 1.0 after removing the kernel module from it. With Ubuntu Hoary the disk works perfectly... I attach some "trekstore" log files.

Like in 113827. When I transfer big file from iPod (usb2) transfer can (too often :[) be stalled. Message in "/var/log/messages": "linux kernel: usb 3-2: reset high speed USB device using ehci_hcd and address 9". Same thing was in SuSE 9.3.
So is this a subfs issue, or a usb issue?
The problem with my Trekstore went away after labeling the partitions with tune2fs. With Hoary everything was OK. Then I had problems with Breezy and SUSE 10. So I think the problems have sth. to to with a Kernel problem, because in Hoary with an older Kernel it worked and with the newer Breezy/Suse Kernels there were these problems. But with the labeled partitions the USB disk is mounted automatically at the right place. BUT a big problem is that I cannot umount them in KDE nor in Gnome because it says: "... is not in fstab so only root can umount this device..." which is VERY annoying. I have to umount it as root in a console which is NO solution! With Hoary/Breezy everything works fine - I can umount it as normal user without problems.
Ok, not a kernel problem, closing...
Sorry, but i think you didn't read the comments. It's still not clear, wheter it's a kernel or an udev problem. Also closing the bug doesn't help improving the still existing problem. If you feel, that is't not your job to fix the problem, please assing to another developer or leave the bug open. It's far away from beeing fixed, and open a new report for 10.1 doesn't make much sense, as the whole history is gone then. If you want to close the bug, mark it as won't fix or whatever, but it's definitely not resolved. Thanks
Created attachment 57808 [details] New log 10.1 Alpha3 I've made some tests with the new 10.1 Alpha3 release. The bug is still here. Pls. read the attached logs. Regards: Janos PS.: I think it's in the kernel or in my IDE2USB firmware.
>or in my IDE2USB firmware. I don't think so. My iPod have the same bug, but only in Linux :) Maybe problem is in "ehci_hcd", because when I remove this module ("rmmod ehci_hcd"), everything ok, but speed (usb1 mode)...
I have the same problem with an external drive, except sometimes it never comes back (not even in 1.1 mode). It appears to be a kernel issue however: http://bugzilla.kernel.org/show_bug.cgi?id=5682 Looks like the cause of it to me, though I could be wrong.

I can confirm that doing: - unplugging my external DVD drive > rmmod ehci_hcd > modprobe ehci_hcd - plugging in drive allows udev to function as intended. Previously, if I unplugged the drive after using it, when i replugged it, it would detect the device, but wouldn't detect any DVD.
(In reply to comment #18) Sorry, forgot to add : using package : kernel-default-2.6.13-15.8 on SuSE 10.0
Seems, that 10.1 beta4 resolves the problem. I will wait for beta5, than close it, if there are no other complaints.
Beta5 works fine for me, too. Closing the bug.
Verified & Closed.
