  I have a Satellite P10-304 and the USB ports not recognize anything that are attached to them. Device Manager tells me that they are enbaled and works correctly. What can be wrong with them or what can I do?

  Hello

  One of my friends has the same unit on the work and everything works perfectly. It uses the USB hub too and have many external devices connected to the unit.

  By the way: something like who can occur if the external device is not removed correctly use safely remove hardware option. If you try to connect any other device after that in most cases it is not recognized at all. In this case, you can restart the device or remove ports from the Device Manager and use the hardware detection to find them again.

  Good bye

• USB does not recognize the Garmin unit. Error "unknown device".

  Recently, addition of windows 7 Home premium stopped detecting my garmin unit. Other USB devices such as my ipod work very well. I was able to detect the Garmin only a few times, he would try to install the drivers, but the drivers would not install. The garmin was working a few weeks ago. Here is a list of what I've tried:

  1. Reset (after all what I try)
  2. Turn off the computer and leave it unplugged overnight
  3. Completely uninstall all the drivers and the software associated with the kid.
  4. manual installation of drivers
  5. uninstall the unknown device and search for new hardware
  6. uninstall the unknown device and do a search for legacy hardware (which produces a device does not not (Code 10) error)
  7. Go back to a restore point before updating the last windows

  Please, any help would be much appreciated. I'm decently computer savvy and have always been able to solve any problems that I have. This one had turn me my wheels for days.

  Thank you

• .chm TOC using variables - print SSL does not recognize anything after the variable

  Here's something interesting that I came across today.  I think that maybe it's a bug in RH 10.

  I create .chm TOCs using variables.  For entries of table of contents of page, a content before the variable in the table of contents entry converts to the table of contents printed without problem.  But any content after the variable is ignored.  It's only a problem with the pages in the table of contents.  Books are very good.

  For example:

  Book TOC:

  "Clinic - {variable} {variable}.

  This translates very well to the table of contents printed in printed documentation SSL.

  Table of Contents Page:

  "Clinic - {variable} {variable}.

  Aside from the link in the table of contents page, the code for the TOC book and page table of contents is the same.  But, for some reason, anything after the * first * variable in the page table of contents is ignored in the table of contents printed for printed documentation SSL.  It doesn't matter if it's another right or variable text.

  

  In the image above, both the "clinic - display the list of participants in the" book of the TOC and TOC page on the left contains two variables:

  "Clinic - {variable} {variable}.

  On the right page "Clinic - Participant list", the variable "screen" is ignored and deleted page table of contents only when the layout of the chapter is created for printing SSL.  HR will remove anything after the first variable in the table of contents page, whether it's a text variable or right.  HR does not remove the antything of a book TOC when the presentation of the chapter is created for printing (visible in the picture above).

  Post edited by: eeddings - added image to visually show the bug.

  When you generate print books will go in the printed document.

  Pages in the table of contents of the document are not based on what is in the table of contents above, but on the topic title.

  Add the variable there and it works.

• Reader superdrive USB does not recognize discs

  I'm trying to save a file to a CD using my attached to a Macbook Air USB superdrive and when I click Backup I continue to get messages that the drive is empty and enter a valid disk.   I have tried various CD and DVD and can not make a backup.

  Because it is likely still in warranty, make an appointment at the Apple Store - Genius Bar store and bring it into service. If you are in the United States or is unable to make an appointment in this way, contact your Apple store.

• Computer does not recognize LaCie external hard drive when it is connected.

  Should I just a 'driver' of the manufacturer so that windows recognize? Help, please.

  The device is a hard drive (250 gb) bought in 2006.   LaCie support has provided relevant solutions.

  I disconnected the USB line, reconnected with the power of the unit it turned on and off while only plugged, unplugged, and made all possible combinations of many times. My computer does not recognize anything.

  I can't find it in my computer, and also, the computer does not list the device in the Device Manager utility.

  I have disabled the Windows Firewall.

  The computer with which the external drive worked and one that currently does not recognize are model computers windows XP (2008).

  Thank you very much for your help.

  Thanks for the reply.

  In the meantime and after reviewing all similar positions, it turns out that find the 'live' usb device does the trick.

  So, other people with similar problems, try the usb cables at the back of the computer (all), then by restarting the connection there.

  It worked for me.

  Thanks again for the reply!

  Hi Alba.

  1. who is the operating system installed on the computer?

  2. What is the brand and model of the computer?

  This issue may be caused if one of the following situations arises:

  • The currently loaded USB driver has become corrupt or unstable
  • Your PC requires an update for problems that could conflict with an external hard drive USB and Windows
  • Windows may be missing other problems hardware or software updates
  • Your USB controllers may have become corrupt or unstable
  • External drive can enter selective suspend
  • Your PC motherboard may need updated drivers

• Qosmio F30 does not recognize USB devices

  My new Qosmio F30 does not recognize USB devices. Displays Device Manager USB ENHANCED CONTROLLER and ROOT HUB works fine, but the machine still wants to install each device but cannot. BIOS version seems to be V1.30. I tried the devices on other machines, and they work fine.
  Is there something that I missed?

  Hello

  Before your shot the beautiful F30 can you please say what OS you are using?
  Did you use the OS from the Toshiba restore CD?
  On this CD, all drivers must be preinstalled and you don t need to install no matter what chipsets or anything like that.

  Windows 7 does not recognize that a Canon canoscan 8000F is as a device when it is connected to the USB port.  Tried unplugging, reboot & reconnect, in different orders, but the computer does not recognize there is.  Tried to install a European website for Canon driver: Scangear CS, 8000fvst8120a_xpen.exe, which is advertised as compatible with Windows 7.   But the installer does not work.

  Hello Graboots,

  Thank you for your message.  You can plug your printer on another computer, in order to exclude the possibility that the problem lies in the printer?  You can try using a different cable, for this rule as well.  Since it is a question of recognition, we remove the external devices before software troubleshooting.  Do you get anything when you plug the printer (ie. a tinkle of connection)?  Please let us know, we are looking forward to hear back on your part.
  See you soon

• "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." Why it does not recognize my device?

  Some time ago I had a huge problem with my computer (I think that my mother-in-law accidentally downloaded a virus) and I took it to a repair shop where they wiped out completely and replaced the hard drive.  Since I got it back when I try to use my wireless mouse and plug the nano receiver he said 'one of the USB devices attached to this computer has malfunctioned and Windows does not recognize it.  Why he says this?  And what can I do about it if anything?  I already tried uninstalling the driver and reinstalling, but that did not work because as soon as I plugged it it again once he says the same thing.  So I don't know what is happening or how to fix it.  Please help me!

• Problems connecting to a projector. Laptop recognizes the new monitor but projector does not display anything.

  I have a Macbook Pro (non-retina display) mid-2012. I have a mini VGA screen that worked throughout the year and all of a sudden, it doesn't seem to work. My computer recognizes the new monitor (screen flickers and flies all content secondary screen) but the projector does not display anything. I tried to reconnect the cable, the cable VGA switch to turn on the projector and turn off, restart my computer and clouds of dust on the connections. Sometimes if I move the connection just that will work, but if I so much as breathe on it or watch funny it stops and I can't get it back.

  Jiggle the cable or adapter is something different, you have a physical adapter or cable problem. Any bit-reversal can help that.
