    Usb devices not mounted or recognised

    Hi, I've had this problem for about two weeks now, and its really starting to irritate.

    All of my usb slots are fine (both in ubuntu and windows), as they have all been individually checked with known working devices.

    The problem is, none of them detect or mount usb memory sticks, mp3 players, or cameras. I can get it to detect and mount usb stick and mp3 player if i plug them in at boot but not after. The camera just doesn't show at all.

    This cant be to do with the individual devices as they have all worked fine since dapper.

    If anyone has any ideas it would be greatly appreciated.
    It's much better to regret what you did, rather than what you didn't do

    Mac,
    I don't necessarily have a solution for you, but I can tell you what I've found out so far.
    I'm having the same problem you are, and I've not found much information about it. There's lots of talk about USB devices not automounting, but very few people talking about our problem.
    Do you, by any chance, know what your USB controller is? You can see this using lspci.
    The only partial solution I've found is to disable USB 2.0 support in BIOS. This seems to work sometimes. From my testing, if you reboot your machine with USB 2.0 off, plug in a USB device, and have it recognized, USB will function fairly normally until the next reboot. The next reboot, USB may or may not work. It's pretty much a crap shoot with each reboot.
    On those reboots when USB does work, my camera, flash drive, USB printer, USB hub, USB HDD are all recognized and function. Not that this is a good solution for data transfer, as data transfer is extremely with USB 2.0 disabled.

    I've got a theory, with no evidence to support the theory, that this is a kernel issue.

    In any event, please post your USB controller here and we'll go from there.

    Re: Usb devices not mounted or recognised

    I'm a newbie, so forgive me if this isn't in the right place, but I can't get my pictures from my Kodak EasyShare C533 camera. Except once. And it just doesn't show up anywhere.

    Okay. F-spot wouldn't open, at all. Period. The first time I plugged in my camera I got a message that said a camera was found, and would I like to import the images? I clicked OK, and then nothing happened.

    I tried to open F-spot, with or without the camera, and got a busy cursor, then nothing. Not even an error message. Checked forums, found a suggestion to try G-thumb if F-spot didn't work. Uninstalled F-spot, and installed G-thumb. Success! Retrieved photos from camera smooth as silk.

    Then I disconnected the camera and took more pictures. Now G-thumb doesn't work either. When I try to import my pictures, G-thumb shows the NAME of my camera, but can't or won't get pictures from it. In any case, the camera doesn't show up anywhere on the system. First I searched for possible solutions, and didn't find anything that worked. So I tried restarting the computer, turning the camera off and back on, and disconnecting and reconnecting the camera, in over a dozen combinations, but nothing worked (and got no error messages to point me in the right direction, either). I then tried various combinations of screaming, vulgar hand gestures, and stomping my feet. That didn't work either. So now I'm asking for help.

    This machine is a "reconditioned" piece of junk that I picked up for cheap cheap cheap after my nice computer died. I installed Ubuntu on it because it was slower than molasses running WinXP, and now it's fast fast fast, but I can't get my pictures! Wahh! Help!


    Here's the information I got from running hardinfo: I can't make heads or tails of most of it.

    Re: Usb devices not mounted or recognised

    irksomekitty,
    Regarding your camera: In those instances when you are unable to download pictures from the camera, does camera show up in the Places menu, or on the Desktop? (Forget about gThumb or F-Spot for now. I don't think either of those are the problem.)
    If the camera does show up in Places, but not on the desktop, then the volume is probably not mounted. Your computer does not necessarily know that your camera is a camera. It looks at it as an external USB storage device. In order to read data from a storage device, whether it is internal or external, the drive has to first be mounted. To mount the volume, click on its' name in Places.
    If it shows up in Places and on the Desktop, it is probably mounted already. In this case, double click on the desktop icon and it should open in Nautilus. At this point, you should be able to see the pictures on the camera.

    Try this and let me know what happens. Sorry if I sound patronizing above with the description of volumes and mounting, but I don't know your experience or knowledge level with this.

    I believe its a kernel issue also. I have a copy of mandriva spring 2008 which has the same issues, while pclinuxos 2007 is using 2.6.18 and all is working fine.

    If anyone knows of a permanent fix, it'd be great.
    It's much better to regret what you did, rather than what you didn't do

    If the camera does show up in Places, but not on the desktop, then the volume is probably not mounted. Your computer does not necessarily know that your camera is a camera. It looks at it as an external USB storage device. In order to read data from a storage device, whether it is internal or external, the drive has to first be mounted. To mount the volume, click on its' name in Places.
    If it shows up in Places and on the Desktop, it is probably mounted already. In this case, double click on the desktop icon and it should open in Nautilus. At this point, you should be able to see the pictures on the camera.

    Try this and let me know what happens. Sorry if I sound patronizing above with the description of volumes and mounting, but I don't know your experience or knowledge level with this.
    It's not showing up ANYWHERE, at ALL. The camera is plugged in, and turned on. I uninstalled G-thumb, and installed digiKam, and once again was somehow able to get my photos... but this might only work once, too!



    ... I'll have to test it.

    At any rate, my ignorance ticks me off. Where's a good place for a newbie to learn more about how this stuff works? Workarounds are okay for a quick fix, but not understanding bothers me. I'm intelligent enough to figure out a way to JUST MAKE IT WORK, if I knew what was actually going on (instead of just randomly trying different things with my fingers crossed).

    Help! Somebody infuse me with knowledge (or point me to a website that has nice, clear explanations, preferably with a glossary)!

    Re: Usb devices not mounted or recognised

    My flash drive worked fine under Hardy until I upgraded to the newest kernel 2.6.24-17-generic. I don't understand how it could be a kernel issue though because I rebooted with 2.6.24-16, and it still wouldn't mount the device.

    Re: Usb devices not mounted or recognised

    krlhc8,
    I agree that, in your case, it doesn't sound like a kernel issue. What is the USB controller in your machine? In my case, on the computer in question, I have not anything installed other than Hardy and USB is sporadic. My controller is ATI SB600. I have another machine, also running Hardy, with an Nvidia MCP61 controller and the USB works perfectly. However, everything I have seen still leads me to believe that it is a kernel issue.

    Mac71,
    Thanks for the lspci. I'm kinda trying to make a list of controllers that don't work correctly. That was my issue when I purchased the motherboard with the currently sporadically working USB. I couldn't find any information about specific controllers or chipsets, other than "If you have an AMD chipset, the board should work fine." Well, my board is proving that theory wrong.

    My solution, on the machine with the ATI controller, was to install a PCI USB controller. It is of Belkin manufacture and now USB on that computer works flawlessly.

    irksomekitty,
    Unfortunately, I don't know of a website with the technical information you are looking for. I've learned what I know over the years of messing with computers. From Commodore 64's and Tandy TRS-80's to the present. I will attempt to answer any questions you have as best I can, though I have only recently returned to Linux, so I'm not a Linux expert, by any means.

    As for your USB problem: Let's tackle it systematically:
    Step 1 - From terminal, type lspci. This will give you a list of all pci buses and devices on your computer, and will include your USB controller. Please include the entire printout of lspci, or at least the USB lines in your next post. Knowing the manufacturer and model, it will be possible to search and see if other people running Ubuntu in particular, or Linux in general, are having problems with this USB chipset.
    Step 2 - Uninstall digiKam and forget about imaging programs for a bit. First we need to get your USB running reliably. Once USB works properly, you should be able to use any imaging program you want to.
    Step 3 - Shut down your computer and plug in your digital camera, and any other USB devices you have, then reboot the computer. From terminal, type lsusb and post the result here. This will show a list of all USB devices currently connected to the computer.
    Step 4 - If any USB devices automounted (you will know this if they show up on your desktop) right click on them and select Unmount, then shut the computer down.
    Step 5 - With the computer turned off, unplug all USB devices, then restart the computer. Plug in your camera, then type lsusb from terminal and post the result.

    This should give enough information to figure out the next steps.

    I did just locate a couple of web sites that may give you some of the information you want. http://www.howstuffworks.com/usb.htm howstuffworks is a pretty cool web site that has all kinds of information about, you guessed it, how stuff works. http://www.linux-usb.org/ has a ton of USB information. Also http://en.wikipedia.org/wiki/USB

    I know this is frustrating, and it doesn't help that you have to wait hours or days for a reply, but hang in there and we should be able to get your problem solved.

    edit - I just re-read your hardinfo from your first post and see that you have an intel 82801 EB/ER USB controller. I find this interesting, because mac71 also has an intel 82801 USB controller.

    Re: Usb devices not mounted or recognised

    Thank you, kgriff. I'm not in a huge rush, and I don't mind waiting for help; this is not exactly a life-or-death situation. I shall follow the steps you outlined, and check out the links you kindly provided when I'm not drowsy and bewildered.

    Irksomekitty out. I'll work on this tomorrow, and keep you posted.

    Re: Usb devices not mounted or recognised

    From my experiances this is a race condition between hal and dbus which happens when the two initscripts are started concurrently by upstart.

    This should not happen because hal initscript requires dbus for starting but instead happens when upstart concurrency is enabled because the scripts have been symlinked with the same number (12).

    The solution is to install hal initscript with S13.

    Try this and see if this corrects the problem:

    Code:
    sudo mv /etc/rc2.d/S12hal /etc/rc2.d/S13hal
    Hope this helps.....
