1039 card shows "Unknown Device"

I recently changed from the internal modem to an external cable modem, with cable hookup through the ethernet port. Now my Maxtor 3000DV external hard drive no longer shows up on the desktop. System profiler shows Firewire Bus with 1394 "Storage Front Panel" and "Unknown Device". The Storage Front Panel is a Maxtor External Hard Drive, 80 GB One Touch. The other (Unknown) should be the Maxtor 3000DV, but it is not showing up on the desktop. Is the ethernet hookup to the cable modem blocking the 3000DV? Or what?

I'm thinking that if you remove all power from the Computer, including clock Batteries, let it set a few minutes, replace batteries, power up, then connect one FW device at a time, it might fix it.

  • Amazon Q&A: E1200 - Shows unknown devices connected

    E1200 shows unknown devices connected I recently bought my first router. My question is that it shows multiple devices attached. When I chect the DCHP table it shows only my pc. Is there something I don't understand?

    Where do you get the info telling you that you have unknown devices connected to your router's network? Make sure to enable the wireless security of the router. Use WPA2 encryption. With wireless security enabled, it will ensure that no one else can connect not unless you provide them the wireless security code.

    What you need is the ACPI ( advanced configuration protocol interface) driver for the installed CPU. You can get that at the processor manufacturers support website. Intel's download center is here.

  • Unknown device - ipod nano fine - problem with windows xp and usb root hub

    Greetings all. I've seen this question come up over and over again and have been working on it following previous posts and posts on microsoft and hp sites for a couple of days now.
    First off - the ipod nano is fine. Works on my son's computer well.
    When I plug it into my 6 months new HP Pavilion laptop it says: 'found new hardware' and goes through the process of installing it, says it's been installed, but then shows 'unknown device'. In Device Manager it tells me there are no drivers installed, but when I try to follow the other instructions on this forum to update the drive to USB mass storage device (usbstor.inf), it tells me the best driver is installed and won't do it.
    Many seem to have this problem with devices other than the iPod on Windows service pack 2 so I went to the Microsoft forums and they seem just as puzzled. I've updated all my Windows & HP software to the latest possible versions. The problem is definitely in the USB. Once, when I uninstalled the USB device and then rebooted the computer with my iPod still plugged into the port, it found my iPod, correctly identified it, and for a blissful moment I thought everything was fine! Then it reinstalled the USB drivers and made a comment to the effect that I should move the iPod to a USB 2.0 port for more effective operation and the iPod disappeared again.
    I have 3 USB ports on my laptop, all are USB 2.0 and all 3 have the same problem.
    I've tried all the stuff people have already said on here...does anyone have any NEW ideas? I'm hesitant to take it in for service because it seems to be a software problem that should be fixable.
    Thanks in advance for your help and sorry about the long post.

    This isn't a solution, but it's something I just tried and it may provide someone additional clues about's going on. I too think this is some sort of USB problem.
    I have 6 USB ports. Two of them are USB 2.0. Since I applied the 03-23 update my computer hasn't recognized my nano at all. I would connect my nano and I couldn't get it to show up in My Computer, in iTunes, or on the far right side of the Start taskbar.
    I just tried plugging my nano into the first USB port of my USB 2.0 pair and left the second 2.0 port empty. I then rebooted with the nano attached. Viola - I get a "Found New Hardware Apple iPod USB Device" message. My nano is now flashing "Do Not Disconnect." A small removeable storage icon with green arrow now shows on the far right side of the Start taskbar. If I click on it (like you're going to eject it) the note displayed says "Safely remove USB Mass Storage Device - Drive (F:)".
    If I go into My Computer, "Removeable Disk (F:)" now shows there. However, if I try to follow Trevor's instructions in another post to "go into My Computer with iPod connected, right click it, wait till the right click menu comes up (could take a few minutes); click Format, . . ." I'm stuck. I do the right click, watch the hour glass and wait for the Format menu to come up but it never does. Eventually the hour glass just goes away. No message, no Format menu. The waiting hour glass just goes away.
    My computer isn't as new as yours, but like you I am completely current on maintenance.
    I'm going to keep trying . . . If anyone has any ideas, please let me know.

  • Iphone 5 fallen in water drained for around 20 secs, kept in rice bag for 2 days, worked perfectly for 6 hrs! now it shows to restore, after restoring during activation it says unknown device contact apple care.

    hello, i have an iphone 5 it just fell into water and was in there for around 20seconds. I've seen on many of websites saying to keep it in a rice bag for 48 hours nd said it may work so i've done the same. I took out my phone from dat rice bag yesterday which worked perfectly alright for 6 hours and then switched off automatically! when i connected it to itunes it detected as a recovery device which after recovery during activation it shows as an unknown device! been working on it soo long! i live in mauritius here i have no official apple store but my phone is still under warranty. Please help me!!

    When your phone was exposed to water, your warranty/support was voided, so you no longer have any warranty. An out of warranty exchange, from Apple, is US $269. Call AppleCare or whoever handles support where you live.

  • Iphone 3G on windows 7 (64bits) shows as unknown device

    HP Pavilion tx2500 Notebook PC
    ADM Turion X-2 Dual core
    Windows 7 - 64Bits
    I downloaded the latest version of Itunes and haven’t been able to use since
    Every time I connect Iphone to computer, PC recognizes (it shows on Portable devices)
    but somewhat shows also in another devices (unknown device) and Itunes doesn't recognize or even shows anything.
    I uninstalled and reinstalled Itunes and all apple software (Bonjour, QuickTime etc) about 15 times every way I could imagine.
    I extracted files (usbaapl64). I tried to update drivers with no success.
    I uninstalled Anti viruses, scanned HD, updated some video/sound drivers
    It works on my husband’s computer (another HP)under windows Vista 32bits but it’s not working on mine for the life of me.
    I can’t figure it out what its causing the conflict and would appreciate any suggestion
    I do not really want to try to jump using the restore since last time I did it I had a hard time to download/update my contacts and settings and ended up having to download MobileMe
    Pls help

    todays update
    It got worse before got better
    I uninstalled and reinstalled Itunes a couple more times. I even tried to install a 32bit version since task manager shows Itunes 32*exe.
    I finally gave in and restored Iphone to factory settings and then my iphone could only call 911 (emergency calls)
    I try to connect again to restore it but it didn't work. I tried the DFU and got a error msg "error-message-0xe8000001"
    I researched the error msg and found something about USB2.0. I went to HP site and downloaded an update for some drivers and voila
    right now iphone is being synchronized
    hopefully I won't have any problems with my contacts like I had last time
    this happened to me

  • Playbook showing as unknown device in desktop manager

    Hi
    Just bought a Playbook and wanted to transfer some files across to it.  Unfortunately I have come up against a fairly major problem with this.  First thing I did was connect it to my PC and start up Desktop Manager, unfortunately the Playbook comes up as 'Unknown Device'.  Tried checking all settings including everuything recommended in article KB27464 with no success.  The Playbook shows as network device in Device Manager in both the PC's I've tried (one runing Win7 Starter and the other Home Premium) and as far as I can see all settings correct but no joy.
    I then tried using the network share option as suggested on the support site.  Typed in the relevant IP address (file:/192.168.1.5) in the run dialogue after truning WiFi sharing on with no luck.  All I get is Windows can't find the relevant folder!  Then tried the same technique but using the USB IP address but still no luck!
    Can anyone help me as after many years of enjoying various blackberry devices this tablet is wearing my patience very thin.

    Hi
    Thanks for the reply, I was going to return the tablet this morning but thought I'd give it another go.  Anyway after turning off both WiFi and Bluetooth as well as disabling sharing I plugged the Playbook in and it was detected!  Anyway now managed to get it synched, updated and bridged to my 9900 so everything's looking great.
    Thanks again for you advice, hopefully I can help someone else in the future as I get to know more about the tablet

  • IMac shows firewire hdd as "unknown device"

    Hi,
    I have an Iomega firewire hdd, that a few months ago worked fine with my powermac. Now I have an iMac Intel and it shows the firewire as "unknown device". I've tried plugging the firewire hdd into two different iBooks and got the same result.
    When the firewire hdd in plugged in, its blue light comes on. But I can't hear the hard drive working (though I can't remember if it made a noise when it was working properly).
    Unlike another post that was similar to this, I cannot change the jumpers, as it is a closed unit.
    Does anyone have any ideas?
    Thanks!

    hmm, sounds as if either the HD has died/ has a loose connector, or the firewire controller had gone kaput, its not that common but can happen, and seing as you have tried it on 2 other Ibooks and still have unknown device that seems to be the case.
    I have had an external enclosure that had firewire and it stopped working but when i took the HD out it worked find, just the box died..
    as yours is a sealed unit id hope its still under warrenty
    Sorry i couldnt be more helpfull

  • "FireWire Unknown device" - but nothing is connected!

    Hi everyone,
    although I have no FireWire devices connected, System Profiler keeps showing an "Unknown device - maximum speed 400 Mb/sec".
    Seems like the FW bus retains the memory of something that was connected at some time, but I cannot reset it. I ran through the suggested "unplug everything, shut down and wait 30 minutes" method, with no positive results.
    Problem is, my Avid Mojo will not run if it thinks there is anything else connected to the FW bus.
    Anyone have any ideas on how to reset the FireWire bus?
    Thnks a million!

    Hi Roberto Servera-
    Did you look with everything except mouse unplugged?
    Have you tried removing any PCI cards if present?

  • Unknown device in device manager after win8.1 upgrade W540

    I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
    I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
    Device manager lists the device in question as follows:
    Device instance path: ROOT\SYSTEM\0001
    Hardware Ids: root\iwdbus
    Device stack: \Driver\PnPManager
