Device Unknown Problem

When I plug my computer, I get a message saying 'Unknown Device' I tried to find a driver but could not find one that helped. If anyone knows what is going on, please help.

Hi
Did I understand this correctly?
You have restored the A500 to the factory settings using the Toshiba recovery procedure and the unknown devices still appears in the device manager?
Thats strange because the Recover disk should set the notebook back to the same state like at the first day of purchase. So usually the unknown devices should not appear and all drivers should be installed properly.
However, I found an interesting and in my eyes useful HowTo document which should help you to find out which drivers are missing in your case.

  • Airport extreme blinking yellow.  reporting "Unknown problem (6rer)

    My airport extreme router has been blinking yellow for a week.  All devices using it are still able to conect to the internet, but all report errors with airport. When i go thru diagnostic steps by way of those messages, i get "Unknown problem (6rer)"  I have powered down the unit and also the cable modem to which it is attached, with no luck.

    If you are using the Lion or Mountain Lion operating system on your Mac.....
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click on the amber dot, and another window will appear to explain why the amber light is blinking
    What is the message?  If everything seems to be normal, the message might indicate that an update is available for the AirPort Extreme.

  • Cannot print from firefox. Get mssg "an unknown problem occured"

    when I try to print, the "save the file as" screen comes up. If I clear it, the "unknown problem occurred--". I can print from other programs.

    I came across the same problem today, also using a 2600N. Window updated the drivers through a Windows update yesterday, so I suspect that's what caused the problem since it was working fine before.
    I tried the reset in about:config and that didn't do jack, but I was able to solve it by removing the printer with device manager and then disconnecting it from my PC, plugging it back in, and letting Windows reconfigure it automatically. It works now.
    Good luck

  • Ipod cannot be restored because of unknown problem (Error 1437)"

    One day when I was listening my ipod when I pass the other song ipod screen freeze and I reset it and when its open all the songs and videos are gone Then I connect it to my laptop and I took the Error says "iTunes has detected an iPod that appears to be corrupted" When I try to restore it through itunes, I take an error message says "ipod cannot be restored because of unknown problem (Error 1437)" And the ipod is not recognised in itunes after this message..Then I searched the help files; I updated my itunes to the latest version, also restart my computer and change the usb port Im trying.. Also tried to update the serial control drivers but nothing's changed..One time I tried to do it in safe mode.. Nothings Changes... I everything I found in apple help files.. I see lots of unanswered questions in many months but Please HELP

    Well it could be dead forever or you might just need some simple repairs. The problem i have seen in some is that when dropped the hard drive either comes loose (easy to fix) or gets killed (little more expensive).
    There could be other problems but i have seen those problems more often than something drastic like the whole board dieing.

  • Hi my iphone4 is stuck on device unknown and it won't let me do anything! It is connected to wifi but it stuck on the one screen.

    HI
    my iphone 4 lost its signal so it was switched on and off again. It wouldn't come back on. It asked to be connected to iTunes, which I did but now it's screen says "device unknown" and won't do anything else. The wifi is enabled but I can't get it to do anything!

    If the computer does not recognize the phone, did you try some of the suggestions mentioned in this article?

  • Hello.  I upgraded my MIFI 2200 (had no contract on it) to a Jetpack (with a contract) when customer service told me this 4G device would use less data because it was faster.  This was not correct.  Anyway, I got the device, had problems, did tech support

    I upgraded my MIFI 2200 (had no contract on it) to a Jetpack (with a contract) when customer service told me this 4G device would use less data because it was faster.  This was not correct.  Anyway, I got the device, had problems, did tech support, re-activated my MIFI.  1.  Decided to return the device. Spent hours with Customer Service, then finally up to Management, they agreed to take it back and void the contact, I sent it back immediately – and instead of voiding the contact they transferred it to my MIFI! Please cancel the contract on the MIFI. 2.  During the short time I had the Jetpack I continually received overage alerts, took it all the way up to 30 GB, each time I backdated the new data plan except twice when customer service did and failed to back date the increase, and once the computer locked customer service out and could not increase.  The end result is I have a $495 bill, many of these alerts were false since I ended up with only 14 MG for the month, etc.  I am asking that my bill be reduced significantly to reflect no overage and to compensate for these problems. Please open up a ticket for this.

    I had Verizon JetPak and you will find it will eat data like crazy. I opted to sign on to ATT Uverse and configured my phones and other devices to the WiFi on the Uverse system. It took about 5 minutes to completed the configuration.  I was using 10 to 12 GB monthly to support 5 devices. Even if you use Verizon DSL, you are still subjected to same GB allotment.  In my area, Verizon DSL is not available. With Uverse, I have 250 GB monthly to use, and I have not even come close to using anything of that magnitude. I reduced my GB package with Verizon to 2 GB per month and since having ATT Uverse, I never use more than 1GB a month with Verizon.
    I have no problem with Verizon cell phone service as we get a much stronger signal where we live than you can with ATT or any others.  It is just my opinion, but if you are running multiple devices off Verizon Jetpak, you will eventually spend a fortune to keep pace.  I pay $60 a month for 18 Mbps speed, although ATT have packages that cost much less. But, it saves me a bundle each month. The cost of Uverse alone is worth not having to run everything through a Jetpak.  
    If you have the  option to use another DSL service provider in your area, I recommend dumping the Jetpak and sign on with another carrier.

  • Adobe print engine failed to output your data due to an unknown problem using modified font

    I have a document I created in InDesign CS5.5 with no issues. One of the fonts had a some issues with how the letters looked, so I modified the font (True Type) with a font editor. The documet on screen looks fine and passes preflight with no issues, but when I try to print it to any printer or PDF (Adobe PDF or Winpdf wirter) I get the error: adobe print engine failed to output your data due to an unknown problem. I also tried to create a document in MS Word with the same modified font and had no issues printing. Can anyone check into the issue with InDesign with this font if I send it to you? I also did try to create a new document in InDesign with just some text using the modified font and it will not print that one either.

    ***Oops. Cross posted. Glad it is working.***
    If you desire to share the fonts I can look at them. Just send me a PM with a link.
    Did you change the internal naming/IDs when you created your varient? If not, try removing the version you began with. Paths all closed, etc?
    Ian's application works fine but I don't use the light version--isn't there some limitation with it?

  • Priemere Pro consistantly crashed upon export, I cleaned media cache and that seemed to help. Now export errors unknown problem... read to uninstall and reinstall and now I can not open up PPCS5

    Here is my problems with Premiere Pro CS5
    When I export a project... the computer crashes.
    I was able to get a tech chat and they would clean the media cache
    so I did that.
    Then, I got an export error "unknown problem" I then read in a forum to uninstall and reinstall Premiere pro
    Now on my very nice relatively newer IMAC, when I go to applications to open it... I can not find a purple tab to open it. It just has a presets folder, then open that and it has styles, templates, textures but, now little purple Pr to open or drag to my dashboard.
    Help PLEASE!!! I have wasted 20 hours of editing time, and work because of crashes, and problems.

  • 11inch air turns off when sleep due to unknown problem/takes awhile to fire up

    Hello,
    Since the update to Mavericks i've noticed everytime i put my macbook air to sleep for longer than a few minutes.. it's shut itself off and when it fire up (after holding the power button for quite a few seconds) it comes up saying it turned off due to an unknown problem.
    This never used to happen, I bought the Macbook Air 11 inch in September so its still fairly new. Is there anything im missing here - everythings up to date. I dont know if i should take it to genius bar yet or if theres something i could try to fix it.

    You are not alone.  This is a very active topic.  See https://discussions.apple.com/thread/5495588?start=0&tstart=0
    The remedy mentioned several times in that thread is to reset SMC + PRAM and in check "Put hard disks to sleep when possible”.  It is not a perfect solution.  The problem reoccurs for some people.
    SMC reset: http://support.apple.com/kb/HT3964
    PRAM reset: http://support.apple.com/kb/PH4405
     > System Preferences > Energy Saver
    > Battery > uncheck “Put hard disks to sleep when possible”.
    > Power Adapter > uncheck “Put hard disks to sleep when possible”.
    If that does not do the job, go to an Apple store for a repair or replacement.
    Actually, given this is an intermittent problem for others, you may want to take it to an Apple store before you try to make it better to have it fail in their presence.  After that try the fixes and if the problem comes back you will have a documented case for Apple to repair or replace the unit.

  • The Adobe Print Engine has failed to output your data due to an unknown problem

    I am currently having a huge problem printing from indesign.<br />I am running CS3 on a hi spec 08 Mac Pro (10.5.2) connected to an Epson 3800 Stylus Pro A2 printer.<br />I keep getting the message <Printing Error: The Adobe Print Engine has failed to output your data due to an unknown problem>.<br />I have tried trashing the indesign preferences, I tried a new account... In fact I have just done a clean install of the entire OS. Just can't get it to print. I did have it printing on this machine before and the same document prints from my iMac.<br />The problem seems to be something to do with the print dialogue. If I print WITHOUT checking the Printer settings in the Print dialogue is sends to the print, but the output is shocking as the paper selection is not right and uses photo black not matt black.<br />When I DO check the printer settings and set it all correctly it gives me the <Printing Error: The Adobe Print Engine has failed to output your data due to an unknown problem>.<br />Anyone else had this or have any thoughts?

    I am seeing this error too, but I've narrowed it down to an isolated set of circumstances. My client has begun rolling out Active Directory integration with Macs on their network. Here are the specifics:
    -- Mac OS X 10.5.4, IDCS3 5.0.3
    -- Using the Directory Utility, Macs are bound to AD with using the mobile account option (user folder is cached locally on workstation, hosted on the network)
    -- The message immediately pops up after clicking 'Print' button in print dialogue.
    -- Printers are a couple of different versions of DocuColor (250 and 260) with Fiery RIP front ends. Print queues are hosted on an AD print server and listed as Open Directory under Kind in the Add Printer dialogue.
    -- Only IDCS and ILCS3 (13.02) exhibit this problem. PSCS3 (10.01), Acrobat (8.1.2) and Safari do not have the same issue, so it appears to be Postscript related
    -- Printers not going through AD (IP or BonJour enabled HP B&W lasers) print successfully when logged in via the networked user. Logging into a local admin account resolves the problem as well.
    -- This issue appears on freshly imaged machines, G5s and MacBook Pros, not just an isolated workstation. So its possible there is a problem with the source image, but it was created by another office and I'm just a consultant onsite at another location trying to sort things out. Other workstations still using Thursby's Dave software for file and printer access, running 10.4.11 do not exhibit same issues.
    -- The console output lists this error when ID fails:
    7/23/08 3:28:59 PM /Applications/Adobe InDesign CS3/Adobe InDesign CS3.app/Contents/MacOS/Adobe InDesign CS3[1374] passwordCallback: didn't find keychain item for "ipp://localhost/printers/DC01_Fiery250_5th";prompting for it
    I have created a keychain entry to match this with no success.
    -- None the suggestions in linked KB doc. resolve the issue. But that doc seems to be outdated as it references CS 1 and 2 versions of ID.
    So, has anyone seen the same issues? AD integration appears to be the common thread, but I cannot find the cause.
