    spontanious usb disconnect troubles


    For quite a while I'm having difficulty trying to access my USB harddisc. With some effort I manage to mount filesystems on it, but every now and then (minutes up to hours apart) the device fails. So I decided to take the device apart and disconnect as much items as possible for the device to keep failing. All I have now is an empty casing, no flash cards inserted, no harddisc inserted, no external power supply, only a usb2 hub and usb2<=>ide bridge (without drive). The disconnects appear far too often to be able to use my external disc, and it especially frightens me to write to the filesystems (although journalled reiserfs). I googled up the error messages below, but so far I haven't been able to resolve this issue.

    I used the gentoo livecd to reproduce the issue on my laptop:
    # uname -a
    Linux livecd 2.6.15-gentoo-r5 #1 SMP Mon Feb 13 20:23:47 UTC 2006 i686 Intel(R) Pentium(R) M processor 1500MHz GenuineIntel GNU/Linux

    But same problem occurs on my desktop machine, running gentoo 2.6.12 and earlier kernels too.

    Any help to resolve this issue is welcome.

    Does the device works nicely on other machines?

    Both my desktop and my laptop computers have the same problem. Both are running linux by the way. I have no clue how to check this behavior on Windows.

    Are you sure this USB drive is OK then? That's suspicious.

    You can try it in Windows as well (I guess it will pop up "New Hardware found" repetitively or something).

    I checked this, but this "New hardware found"-baloon only pops up first time you connect a device to a Windows (XP) system.

    Same problem

    Hello out there,

    just to strengthen the suspicions that there is a problem that does not only have to do with the hardware:
    I have got an
    Fujitsu-Siemens Amilo-D (quite old) running either Kanotix or Knoppix (up to 5.0).
    Attached to this is an ultron uh-420 PCMCIA <-> USB 2.0 card (NEC chipset).
    Attached to this is an ICY BOX case including an USB 2.0 <-> S-ATA Bridge.
    Build into this is a Toshiba HDD (exact model not known at the moment, newly bought).

    Same problem, only that the case disconnects much earlier than posted (seconds, not minutes).

    The ICY BOX runs ok on two desktop PCs and a newer Fujitsu-Siemens Amilo D with USB 2.0 built in, using both linux (Knoppix 5.0) and Windows there (but, ob course, without using the PCMCIA-card).

    Interesting detail: The hdd fails not so quick if I link in an USB-2.0 4 Port HUB from digitus.

    In the PCMCIA slot a Card-Adapter with a CF-Card works fine (well, very, very seldomly it disconnects, too).

    Attaching an external power-supply to the PCMCIA-card or the hub does not make much of a difference.

    Any hints are welcome...

    spontanious usb disconnect troubles

    Hai,

    I am experiencing the same problems.
    Hardware: Dell Latitude with Windows XP on hard disk (completely NTFS)
    USB-drive: IBM Travelstar (80 GB)
    partitioning: 40 GB NTFS, 1 GB (mountpoint /boot), 5.9 GB (mountpoint /), 4.9 GB (mountpoint /home), 1.9 GB (swap)
    GRUB installed in MBR of USB drive
    Linux distro: Mandrive 2007 (Free)

    Upon boot the above mentioned error occurs. However ...
    1) put in a Knoppix CD/DVD and boot from the CD/DVD-drive with the USB drive disconnected
    2) once Knoppix has started, attach the USB drive; the partitions will now be 'auto-mounted'
    3) shutdown Knoppix
    4) reboot (while pressing F12 --> Dell boot-up menu appears)
    5) select booting the USB-drive; select Linux from the Grub-menu ...
    6) and watch the wonder of mandriva running completely from the USB-drive

    It is a work-around because the next time booting is attempted without the procedure as described the error occurs again.

    I am aware this won't help against the observed disconnections during file-transfer and a solution has to be found for this. But at this stage I am still not quite sure where the problem lies.
    BTW The mounting has to be performed using Knoppix (or perhaps any Linux installation). Doing the same using Windows XP has no effect, the problem will still occur.

    Please excuse me if I'm not understanding your problems or my attempt at a solution is too simplistic, but have ya'll tried using a differnet USB cable or connector if that's possible to do? (I say "possible to do" since I'm not at all familiar with the hardware described here.) I had very similar disconnect problems with a brand new HP USB printer and brand new USB cable. After pulling my hair out for a week or so, I changed the USB cable and that fixed it. USB cables can go bad. Again, please forgive my ignorance if I'm not understanding the problem...

    Angry

    Thnx for your suggestion. I completely forgot about this thread I started. It appears that my IBM Thinkpad T40p suffers from a _hardware_ problem. Several of my collegues experienced the same problem until the laptop itself was replaced. The real problem though is that after repair my supplier cannot guarantee that the USB ports will function properly.
    Faulty USB2.0 ports on WinXP do all kinds of strange things until I receive a message like: This device will perform better when connected to a USB2.0 interface.
    After that message the system is stable, but my USB functions at 1.1 speed

    I was seeing something similar with my brand new PowerSpec usb IDE external hard drive enclosure. namely the following when I attached the device:

    ehci_hcd 0000:00:1d.7: port 2 reset error -110

    a simple jiggle of the cable and a different port fixed the problem!
