• Cannot access the usb Gizmo.

  Original title: bo

  It cannot access usb Gizmo! Crucial storage device. Window 7 it shows in Device Manager, but do not have access to the device. I used this drive for 4 years, I need the data on it.

  Hello Bobby.

  Thanks for posting your query in Microsoft Community.

  • Do you have an error message when it is not detected? If YES, what is the exact and complete error message that you receive?

  I understand that the USB device is not detected by your computer. The question may arise if the currently loaded USB driver has become unstable or damaged or if your PC requires an update for problems that could conflict with a device USB and Windows. This can also occur if your USB controllers may have become unstable or corrupt. So, I would suggest trying the following steps and check if the problem persists.

  Method 1:

  Please try the fixit (s) provided below which will help you solve common problems associated with devices and USB ports.

  • Hardware devices do not work or are not detected in Windows
  • Diagnose and automatically fix the Windows USB problems

  If method 1 does not work, try Method 2.

  Method 2:

  Remove and reinstall all USB controllers.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of the categories of equipment, locate and expand Bus USB controllers.
  3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
  4. Restart the computer and let the USB controllers get reinstalled.
  5. Plug in the removable USB device and test to make sure that the problem is solved.

  If the problem persists, go to method 3.

  Method 3:

  Disable USB selective suspend framework. This method prevents your power off USB device.

  1. Click the Start button, type power management in the search box, and then click choose a power plan.
  2. Next to your currently selected plan, click Change Plan settings.
  3. Click change advanced power settings.
  4. Click in the box USBsettings, and then expand the USB selective suspend settings.
  5. Click on the area, and then click the menu drop down and select disabled.
  6. If you use a laptop, click the cell, and then click the menu drop down and select disabled.
  7. Click apply, and then click OK.

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

  Kind regards

• Cannot access the USB storage

  I had an E3200 for over a year and all is well. I have a 128G USB plugged into the usb port and had no problem sharing the content with any user connected to the router. In the last 2 days I started to have access to the USB problem. When my WIN8.1 came, I saw notification saying: "unable to cnnect to all network drives" and I can't go to the USB. The other function of the router is fine (each user can access the internet without problem). I tried to check using the administration interface. But 192.168.1.1 has not returned the admin login (via IE or Chrome).

  I put off and then power on the router, I can only get to the admin and saw no problem with the USB Stoarage and I was also able to get the USB content on my file Explorer.  It remained OK when I was using my laptop (maybe 1 or 2 hours). But the next time I turn on my laptop, I had the problem once again (impossible to get to the USB drive and 192.168.1,1 are not returns login prompt).  Power off and power on the E3200 will do again. Any suggestions on how I can know what is the problem?

  To help us isolate the situation, try to access your files using other laptops. If all devices are affected, it would be better if check you if the firmware is up to date. If this is the case, you can try to re-flashing the firmware.

  To download the updated instructions and the latest firmware, go to this link, http://support.linksys.com/en-apac/support/routers/E3200.

  It is recommended to do a factory reset after properly updating the firmware. Reconfigure the router and observe its performance.

• Palm Pre more - broken digitizer - cannot access the usb mode

  Hello.  I recently dropped my phone, making the unnecessary digitizer (yay!).  Since I tried to reach usb via white + sym + shortened u mode, nothing works.  I've searched the forums and they all State that it should work correctly.  I remember working until I upgraded to 1.4.5 with verizon.  Is there something in the update that may have caused it to stop working?  Yet once, I tried white + sym + you all at the same time, separate both, with different brands/models/3 os for portable computers.

  Any ideas?

  Just so you know, when I do not press the three keys together he does nothing for a few seconds, then opens and behaves as if I touched u 5 times, adding a Symbol pop up every few seconds.

  Nevermind - 15th time is the charm and finally it worked.

  Thank you!

• Cannot access BIOS when OS disk encrypted w / Bitlocker, starting on the USB key is not unlock disc

  Hello

  I enabled Bitlocker on my Acer Aspire 5315. The system partition is encrypted and the data partition. My motherboard doesn't have a TPM chip, so I opted for the unlock with a USB key.

  When I start the PC or wake them from their hibernation, the splashboot (with the logo of Acer) BIOS screen does not display the information below on how to access the BIOS (press F2) or the boot menu (F12). And therefore I can't access those as I used to.

  BitLocker does not account for the USB key, then asks for the password to unlock the HARD drive. Then Windows starts very well.

  However, restart (by a Windows or after you have entered the wrong password Bitlocker too many times), the BIOS splash screen is normal (with how access BIOS and boot menu), I can access BIOS by pressing F2 AND succesfully Bitlocker unlocks the HARD drive with the USB flash drive without having to ask for the password.

  So, my question is how Bitlocker unlock the HARD disk automatically via the USB when the PC starts?

  Thank you for reading.

  Note: I posted this question on http://social.technet.microsoft.com/Forums/en-US/w8itprosecurity/threads they suggested that I ask the Acer support.

  Thank you also get answers in the TechNet forums.  I'm sorry that you were unable to get a more complete answer it.

  We suggest that you uninstall BitLocker and decrypt the drive to determine if this restores your ability to access the BIOS.

  Hi Jon0909,

  The error that you received can be for several reasons. I suggest you try the following steps:

  Method 1: Run the fixit available in the link below and check if that makes a difference

  Tips for solving problems of USB devices

  Method 2: This normal matter as a result of a conflict between the USB and other USB (Universal Serial Bus) connected to the computer.

  (a) disconnect all the external devices connected to the computer to expect the mouse and keyboard, check if your USB key works.

  (b) If this solves the problem, and then add back both devices until you discover the piece of hardware causing the issue.

  If the problem persists, you can contact the manufacturer of the device for any known issues

• WES7: 'Windows cannot access the installation sources. "Check that the installation sources are accessible and restart the installation.

  I try to install Windows Embedded Standard 7 on an vacuum Compact Flash 4 GB but when installing, I get an error message "Windows cannot access the installation sources. "Check that the installation sources are accessible, and run the Setup again."

  I created an answer file with the Configuration of Image Editor and I created an Image of the IBW of my answer file. All the files and the Image of the IBW (738 MB) files are copied to a USB bootable 4 GB. I inserted the Flash DRIVE to a computer with a Compact Flash 4 GB (which contains only a primary NTFS partition set as Active) and it starts on a USB key. IBW Wizard starts and I followed the instructions until the disk selection step. I chose the disk and partition of Compact Flash and I press the next button. First 2 installation steps manage (copy of Windows files and extend Windows files) but 3rd step (installing features and updates) failed with the error message "Windows cannot access the installation sources. Check that the installation sources are accessible, and run the Setup again.'.»

  I tried to do the same thing with a Compact Flash 4 GB, which contains 2 partitions: a primary NTFS defined as active and a system partition, but I got the same result. Then I tried to install it on a Compact Flash 8 GB which contains 1 single defined primary partition as active and I managed.

  Problem is that I must install on a Compact Flash 4 GB.

  Can someone help me please?

  I recently bought Toshiba Satellite L20-100
  I installed a USB in Kingston datatraveler flash drive and windows recognized it without problem.
  but when I open my computer there is no icon for the reader (it works on another computer well).
  the drive is recognized in Device Manager, but it is not given a drive letter.
  When I open disk management and try to give it a drive letter it still does not show on my computer even after a reboot.

  Although I can access the disk management flash drive and can open, copy & paste the files & to her.
  same problem happened with a card reader.
  other USB devices like cable modem & mouse work well

  What is the solution

  Hello

  Is it possible that the USB is not formatted? Try changing the file system on the USB key.
  You can also try to change the drive letter because the letter assigned automatically sometimes gives some conflicts with other readers.

  Second possibility:
  You can try to clean all the USB stored device settings and let Windows refresh their.

  Create a file with Notepad containing the following lines and save it as a BOOKMARK. REG
  -cut after this line-
  REGEDIT4

  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment]

  "DEVMGR_SHOW_NONPRESENT_DEVICES" = "1".

• Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

  Hello

  I recently changed to use AVG free Antivirus Vista 2010 edition and since then (next day) seems to be locked out almost everything on the computer other then IE.  Open any kind of .exe translates into "Windows cannot access the specified device, path or file. You don't have the appropriate permissions to access the item. "I can access the Control Panel, but when I try to run something (a user restore Sys account) nothing happens or I get the same error.  I can not even access/cmd?

  Operating system is vista 64 bit home premium
  Computer has 1 which is defined as administrator SP1
  Tried to do a restore of the system in normal mode and safe, the two will not start.

  I have a feeling I know what the problem is, that when you look at the properties > Security "Progam files" in the 5 groupnames user administrator has not enabled in the lower area of permissions?  Guess a virus has locked all accounts to use the machine key files? (When editing and allowing the admin to have full control etc. in written authorization, I get an "access denied" Message.)  Be honest this really problems out of my PC knowledge, I would usually just reformat if I hit I can't solve a problem, but this time reformating is not the best option.

  Thanks in advance for any help, I would really appreciate it, it left me speechless!

  PS. read through the similar questions and have used the "fix windows' programs, with nothing working or me being not able to access something used.

  Hi Dany88,

  First of all, I would say that you uninstall security antivirus vista 2010 of computer software, since there are several questions on the computer after installing. This software may have created conflicts between other programs on the computer.

  As you face problems to access items from 'Control panel', I would say you visit the security software vendor's Web site and search a tool of suppression using which you can uninstall the software.

  Important: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

  If questions are set after uninstalling security software, I suggest that you change the security antivirus vista to some else software or contact the vendor of the software for more information.

  I would also say that you are investigating the computer by using the methods mentioned in the link below.

• Windows automatically restarts constantly, cannot access the system restore point, cannot access the computer in safe mode

  Hi all

  For the not 24 hours I tried to access my computer in normal mode. When I turn on the pc, it says "configuration data 1 of 3 steps...". 0% complete"he never spent 0% and within seconds, it automatically restarts and starts again. It's so frustrating! I have a windows vista pc (purchased in ' 06). I can only access my desktop in SafeMode.

  I tried to perform a system restore, but not like he says "recovery disk is not the restore point selected. What should I do? I tried to manually create a restore point, but cannot access the system and Maintenance, while in safe mode. I can't do anything but literally access the internet. How can I get Windows back to factory settings it is with these limited resources? I have a Dell reinstallation DVD.

  I searched my programs and found that recently Windows automatically updated and downloaded "Microsoft Powerpoint Viewer" and "for 2007 Office system Compatibility Pack '. Now, I think it has something to do with it, because they were the most recent updates, before the pc crashed. But I also fear that it may be a virus, which has completely hijacked this PC. How am I supposed to get rid of a bug, if I can't even get the necessary antivirus?

  Sorry for the ranting, but it's so stressful when my pc is completely down. Please, please please help me. Thank you in advance for reading this same!

• Windows cannot access the specified device path

  I have a HP 2000 laptop with windows 7. I had problems playing a dvd. I can burn images and photos of viev on cd. When you try to play a dvd a message-" Windows cannot access the specified device path. You can have not permissions to access this item. "I uninstalled the drive so it is reinstalled on reboot of windows. I used to get a flag asking what program to open with. Now to see "cd" should open in my computer.

  I use Google chrome.

  Hey @Stern07 ,

  Welcome to the HP Forums!

  I understand that you are unable to play the DVD on your laptop of HP 2000 by using Windows 7.

  There may be an easier way to solve this problem, but it's the method that I am referring usually to when having this problem:

  1. launch Regedit (Windows key + R > type regedit > click OK).
  2. navigate in the tree of HKEY_CLASSES_ROOT > DVD > shell > play > order.
  3. double-click on the (default) value on the right side of the split dialog box (String edit dialog box should appear).
  4 copy the contents of the value data field.
  5. click Cancel on the dialog box change the strings.

  Figure 1:

  6. right click on the right side of the split dialog box
  7. Select new-> expandable string value

  Figure 2:

  8. just press ENTER if the cursor is what allows you to change the name of the new value
  9. double-click on the new value that you just created (Edit String dialog should appear)
  10. glue the string that you have already copied in the value data field
  11. click OK in the Edit String dialog box

  Figure 3:

  

  12. now on the left side of the split dialog box, highlight the folder HKEY_CLASSES_ROOT\DVD\shell\play\command
  13 right-click and choose export.
  14. save this file in a location of your choice and a name of your choice.

  Figure 4:

  15. close regedit.
  16. go to the location you saved the file.
  17. right click on the file, and then choose the Edit option (expected to launch the file open in Notepad (or any text editor).
  18. you should see something similar to (not just copy and paste what I have below, because this PC has installed WinDVD):

  [HKEY_CLASSES_ROOT\DVD\shell\play\command]
  @= "Files \"C:\\Program (x86)\\InterVideo\\WinDVD\\WinDVD.exe\ '%1'.

  19. now delete the first line:
  @= "Files \"C:\\Program (x86)\\InterVideo\\WinDVD\\WinDVD.exe\ '%1'.

  20. now replace all in front of the remaining line with just the character = @, final result should look like:
  [HKEY_CLASSES_ROOT\DVD\shell\play\command]
