Satellite L670 - unrecognized USB keys

I have a Toshiba Satellite L670 with Windows 7 64 bit Home Premium edition.

Recently, I bought 3 keys usb SanDisk Cruzer, 2x8Gb, and 4 GB. Have you tried multiple USB ports on this computer, but the same result. The computer recognizes that the SanDisk Cruzers, because it makes the sound when the USB drive is plugged into the machine, but it does not appear on the file manager or Explorer windows of this machine, so can not use the USB.

I moved that the USB stick to a two other machines of Windows 7 (Home Premium version). The USB is immediately recognized by the Office else opens and is available in the windows Explorer, with no problems. I found a temporary solution of desconecting my Toshiba of the cable of power supply and after reboot, the sticks are recognized, but only for 10-15 minutes.

very delicate situation, please help!



Well, if the USB is recognized from another computer USB sticks seem to be ok and it must be a problem of your laptop.

Have you checked the Device Manager if all USB ports are recognized correctly or is there a yellow exclamation mark in the Device Manager on the USB ports?

I had a similar problem with the USB ports, so I removed all the USB ports in Device Manager (right click > uninstall) and then I rebooted the computer. After that, the ports have been recognized again and I could use my USB devices again. :)

    I think that you need to reinstall the chipset driver:

    * Note *, I found in this forum that drivers from the chipset built into the display driver, then I guess you have to install the display driver.

  • Satellite L670 - missess keyboard keys

    Hey all, had this problem since the new - November 2010.

    I've seen several threads on the same issue, but above all, all have been solved by an update of the BIOS.

    I did this update of the BIOS when it came out and everything was fixed.
    So long that I have been using an external keyboard, but I decided to unplug the unit yesterday and once more the problem occurred.
    It took about 3-4 minutes to type while it should take me less than a minute.

    Here is an example of a sentence:
    "I have a keyboard problem which is irritating a me lot"-FIXED
    "I am avea keyoard isue wich is irriatin me a lot"-RAW

    Thank you


    You have installed an additional driver for this keyboard? If so, I would recommend removing this driver. For external mouse and you n t need special keyboard drivers, the internal Windows driver is enough and can be used for this.

    In addition, enter the BIOS setup and load the defaults (F9 key). Then save settings and exit the BIOS.

    It works again?

  • Satellite L670-1EE - reinstallation of Win 7 - key not readable series


    I bought a Toshiba Satellite L670-1EE January 2011
    Now the system completely crashed and I need to reinstall from scratch.

    My problem is, that the first 5 digits of the product key Microsoft are not readable.

    Are there opportunities to get the key, or can I use a special image of Toshiba to retrieve?

    I can't access the installed windows, fails to start, I tried a recovery with a DVD of victory but it didn't work, so I need to reinstall it.

    > My problem is, that the first 5 digits of the product key Microsoft are not readable.
    This key cannot be used as part of the new Windows 7
    It is an OEM key that belongs to the image of Toshiba. For the most part, these keys don't work.

    The point is that Toshiba preinstalled system has already been activated in the image of the Toshiba.
    But there is no need to be activated after the recovery procedure.

    So if you want to use the own system of Windows, you must purchase a license from Microsoft.
    In case you want to use the image of Toshiba, you must use the Toshiba Recovery disk that probably, you have not created in the past. Right?

    In this case, there is another option: you can order this disc from here:

  • Re: My Satellite L350 does not recognize USB key

    I have a Toshiba Satellite L350-235. It suddenly stopped recognizing my usb key that I use every day. Normally, he would say "new hardware found" and allow me to click on the F drive, now I get nothing!

    Can someone advise me?

    I guess that the USB ports are working properly if you connect another device; something like USB mouse. Right?

    In my opinion, you should test the USB in USB ports.
    You can also try to remove the USB controllers and hubs from the Device Manager list.
    After restarting of new laptop, (ports) USB controllers must be recognized, and then you could connect and test the USB again.

    In the event that the USB is not recognized by one of the available USB ports, try to connect to another USB key.

  • Satellite M40-237: CD Boot does not not + is possible startup USB key drive

    * Model: Satellite M40-237 (PSM40E) *.

    I decided to reinstall windows, my hard drive is now formatted. So as usual, boot from the Windows CD is necessary to start the instalation but it does not start. I never had problems like this, always worked boot. It's as if there is no bootable CD in the drive (but it is bootable and it works on another PC).

    -J' have the latest version of the BIOS
    -The BIOS detects the optical drive and everything is ok, HARD is the ODD main drive is secondary
    -J' tried selecting the boot priority, with F12 and/or the BIOS setting but it works anyway

    What could be the problem here? Drive does not properly (hopefully, that and not something worse)? I had some problems with the drive I have (...) before, but it reads the disc normally and as I said start was working fine before. I cleaned the lens a bit, disconnected it and it put. Is there something more, what can I do?

    I'll try to find someone who has the player that fits so I can try with that one, but who knows when is what will be.

    Now, here's the second question, which I've linked to this. Because my laptop is practically useless now (I can't install anything), is it possible to boot from a:
    (a) optical drive USB external
    (b) USB flash drive

    BIOS on this laptop has no USB boot option, it has HARD drive / CD / floppy / network. But I red somewhere this FDD = USB legacy emulation is enabled.

    If that is correct, I should just plug in the USB key and select FDD as boot option? If I can't find a USB optical drive, I thought make it bootable USB flash drive and copy the installation of windows xp on it. So once it starts in DOS I start just the installer from the key.


    First I must say that the initialization of memory flash USB (USB key) is not possible and you shouldn't t waste time to try this.

    With regard to your reader of CD/DVD boot problem
    Well, it s really strange, it sounds a bit like a sort of master/slave/c-salt settings problem. But generally, you should get an error IDE (#0 or #1) if one of the devices (ODD or HARD disk) would not be recognized?  :|
    This whole thing seems mysteriously
    There may be a firmware issue

    Several months ago a friend of mine was not able to boot from the CD.

  • USB key used in iMac unrecognized by any other device

    Hi all, I recently encountered a problem using USB keys with my iMac 2010 10.11.3 running OSx.

    My iMac will recognize UBS sticks and allow me to save documents and files for them, but when I insert into any other device (e.g. a few friend PC and Macs, professional printers to Officeworks etc.) the USB stick is not recognized and does not see the same on their system.   Then when I insert the USB in my iMac, it is recognized immediately as well as its content.

    Before that, I was able to share files and documents with family, friends and clients on USB with no problems at all.

    I tried a variety of different USB keys (old and new) and what is happening to all of them, whatever the brand, age, size, etc.   Is produced only for a few months and at first I was in denial and thought that it was my friend PC, but now I see that it is certainly a problem with my iMac.  He may have started happening around the same time that when I upgraded to IE Captain earlier this year.

    Any ideas please?

    Thank you.


    The fact that this happens with different computers suggests that the problem could be the configuration.

    Go to Applications/Utilities/Disk utility. Insert your flash key and look at the settings. It may look like this:

    Everything on this list must be verified. While you're there, see if your USB is correctly configured:
