• Some USB devices are more recognized when plugged after upgrading Fusion 7

  After reclassification of the merger of 6 to 7, some USB devices, specifically webcams is faster to connect to Windows (guest) or Host (osx).

  They also no longer appear in the USB & Bluetooth under the Virtual Machine settings.  Anyone else see this problem?  Try to understand this point, I completely uninstalled merger to try to solve this problem.  Webcams work fine under OSX itself and are usable.

  7 merger supports a virtual USB camera, that can be added as a new device in the virtual machine settings. This allows the physical camera (USB or integrated PCIe FaceTime HD) to share between the host and the VM at the same time.

  There is currently no option in the settings of the VM to UN-hide USB cameras for passthrough to the virtual machine, but it can be done with a preference.

  Edit the ~/Library/Preferences/VMware\ Fusion/preferences file and add the following line:

  vusbcamera. PassThrough = 'TRUE '.

• Windows 10 Device Manager: "unknown devices", ACPI (Aspire V3 - 112 p)

  After a new installation of Windows 10 (64-bit / Education version) on my Aspire V3-112 p-P5B3, I have yet three "unknown devices" in my device manager and a warning about my 'SDA Standard compatible SD Host Controller'. The first three say «Drivers not installed...» "and display in the 'Détails' tab the" property: device instance path "with the" value: ACPI\INT33FC\n ' (n = 1,2,3). The "SDA". "says"device pending on another device... ". ». So I think that the last problem could somehow be based on the first three problems (?).

  I installed all the drivers on the Acer site for win 10/64 bit.

  I tried to update the drivers in Device Manager... the problems are still there.

  I used the "driver update utility" Intel... the problems are still there.

  I found some clues on the web about "ACPI\INT33FC\n" - but above all, in my opinion, the strange sites for updates of drivers. But somehow, I don't think these pages...

  Someone at - it a solution for this problem? Or the same problem?

  It's a serious thing? Should / can I ignore it? Maybe a future driver updated by Acer?

  Any help is welcome! Thanks in advance!

  ACPI is part of the Intel IO drivers:

  http://global-download.Acer.com/GDFiles/driver/IO%20Drivers/IO%20Drivers_Intel_603.9600.1948.28229_W...

  Sometimes you have to force the installation manually, then go to ACPI peripheral unknow, update/install drivers manually search for and navigate to the folder drivers and let windows choose the good.

• Re: Equium L20-198 - in Device Manager unknown devices

  Hello
  I have a PSL2ZE Equium L20-198.

  I have trouble with the drivers provided by this site everytime I try to install the driver it stops telling me that the chipset is not supported by the program, so I have these unknown devices left to solve

  Ethernet controller
  modem PCI
  SM bs controller
  controller of SB
  VGA controller

  And even if it is a wireless switch (and it works IE turns the light on). I have no software or the details of the installed wireless (standard) whatever it is!
  Not there at - it no utility driver like all the drivers in one of toshiba!

  Thanks to anyone who repiles in advance as this is driving me crazy!

  Hello

  Do you have what OS installed on your Equium L20?

  Normally, you can download all the drivers on the Toshiba site. Did you check that?

  I had a similar error message if I tried to install a new driver from chipset, but it worked if I installed the driver in the Device Manager with the Advanced installation order.

• Device Manager - unknown device + Hig Defintion Audio Device (Point of Exclamation)

  Hello

  I hope that someone can help you. The hard drive on my laptop of HP ENVY TS 15 (product number: E3S19UA #ABA) out crapped and I reinstalled Windows Enterprise 8.1. I downloaded and installed all the drivers from the HP website. When I look at the Panel, I have an "unknown device" and in the audio, video and game controllers, I have an exclamation mark next to the high definition Audio Device.

  I installed the HP Support Assistant and let it do its thing. That has not fixed the problem. When I look at the properties for the unknown device, I see the following in detail: "ACPI\HPQ6007\3 & 11583659 & 0" regarding high definition Audio, I see the following in the general tab:

  This device cannot start. (Code 10)

  {Operation failed}
  The requested operation failed.

  When I try to update the driver software fo the High Definition Audio, I get a message that "Windows has determined the software driver for your device is up to date.

  Don't know where to go from here. Any help or words of wisdom would be greatly appreciated.

  Thank you

  -Val

  You are the very welcome.

  This is defininitely the driver you need and you need to install it manually.

  Run the driver again.

  Go to Device Manager and click on the unknown device needing driver.

  Click the driver tab.  Click on set to update driver.  Select Browse my computer for driver software, and find the folder of the driver that was created when you ran the driver.

  This file will be located in C:\SWSetup\sp66078.  Make sure that the include subfolders is selected and see if the pilot goes like this.

  If this does not work, then back to her browse my computer for driver software window and then select Let me pick from a list of drivers for devices on my computer option, then select Have Disk and browse to: C:\SWSetup\sp66078\InstallFiles\Win8_1\accelerometer and select the HP Mobile Data Protection sensor from the list and see if the pilot goes like this.

  The HD audio device is the audio device Intel HDMI which could not install when you ran the graphics driver, so run it again and if it does not install, manually install the driver using the same procedure that I posted to the 3D driveguard.

  If it doesn't, then I remove the driver and tell you where to get the driver from, as I did for the above device.

• Cannot see the usb device manager devices or windows Explorer.

  I use windows 7 64-bit. I have a certain external drives connected vis USB everything works OK when lit.

  I have a video camera Digital Sony connected to usb, which gives a 'bong' sound to indicate that it is connected, but I do not see in windows Explorer or disk management. The camera itself acknowledges that it has been connected to my PC OK. I tried the camera using usb different positions, still no visibility? Help, please!

  Have you selected the right mode of the camera for connectivity? For example, the PictBridge and mass storage mode are usually present in a camera. If not select any mode, Windows shows a device is connected, but it cannot access anything whatsoever to the camera.

  Also, have you tried to change the cable?

• URGENT: Some USB devices no longer work in Fusion 3!

  I used 2 Fusion (and its minor updates, through 2.06) on my MacBook Pro.  I use this machine for multimedia player for a high school variety show which I am the technical director.  I use a few pieces of music via iTunes on the Mac side, and a few Powerpoint/PDF slideshows (video content all) through my virtual PC machine.

  Side PC is necessary because I have been connecting to a Casio LCD projector wireless.  This connection uses dual USB adapters, one for the projector and the other for the computer to connect.  It worked perfectly throughout Fusion 2.06, and I've never had problems.

  However, this morning, I downloaded and installed Fusion 3, and I am regretting doing so.  My virtual machine will not recognize or even feed of Casio's wireless USB adapter.   I tried everything to try to remedy this.  Our last rehearsal for this variety show is tonight, and the two representations are the next two nights.  If I don't get this situation resolved in the next 4 hours, we are irrevocably screwed.  We have no way of any video content of the project.

  We know that Casio USB wireless adapters are not compatible with 64-bit OS, which is one of the reasons that I am running XP SP3 on my virtual machine.  Fusion 3 for Snow Leopard support (and its associated 64-bit architecture) would be the problem?  I'm not under Snow Leopard on my Mac, but I'm just speculating...

  Also, is there a quick way to "roll back" Fusion 2.06, since I know that worked well with these devices?

  Please, if you please, please help and fast... in fact, if you wish, you can call me: 651-210-5998 and ask for Mike.  Thank you.

  However, this morning, I downloaded and installed Fusion 3, and I am regretting doing so.  My virtual machine will not recognize or even feed of Casio's wireless USB adapter.

  Not giving power is really strange, I don't think he has everything what we could justify this.

  I think that it is probably independent.

  Also, is there a quick way to "roll back" Fusion 2.06, since I know that worked well with these devices?

  Yes.

  1. If you updated the tools in the comments, uninstall them.

  2. Uninstall the Fusion 3

  3. Install Fusion 2.0.6 http://downloads.vmware.com/d/info/desktop_downloads/vmware_fusion_for_the_mac/2_0

• Basket PXI in Win 7 Device Manager unknown device

  I'm dealing with a flakey PC that don't become flakey recently, and I don't know why...

  The problem I see is that the PXI basket is a unknown device in Win 7 peripheral Manager.

  Is there some sort of service or the driver available to fix this?

  I am using a third party card that was installed and working on this system for over a year

  and have swapped it out and also swapped the motherboard. I contacted the technical support of the mfg and this error only

  appears when the PXI ((NI PXIe-1065) basket is connected via the NI PXI-PCI8360.)

  How can I fix it?

  Thank you

  

  Hey robojeff,

  I think that what we are looking for is PXI Platform Services (http://www.ni.com/download/pxi-platform-services-15.0/5404/en/).

  It is the main factor that makes the PXI accessible to the computer systems. Let me know if that helps!

  Best,

• Device Manager - unknown device (Win 7 64)

  When I go to properties / details / Hardware ID value is: root\sscbfs_storlib_bus3.

  It's a SugarSync device according to internet. My first question is, use SugarSync? If so, you should then contact the people for their support and see what happens. It seems that it might go away if you disable the starter, but I'm not sure if that's what you want to do.

• USB device recognized on Windows 7, but not Windows XP

  Last week, some of my USB devices need not be recognized on my Windows XP SP3 laptop.

  First of all, it happened with 2 external USB HDD connected via a mini USB hub. Connecting them individually did not solve the problem. The error I got was:

  USB device not recognized. One of the USB devices attached to this computer has worked and Windows does not recognize.

  More importantly, the laptop is no longer recognizing my USB thumb drive, which works perfectly on my Windows 7 machine to work.

  Can I reinstall my USB drivers? Just remove the USB devices, reboot and let Windows reinstall them? They need to be specific to the manufacturers of the drivers?

  I deleted it and reinstalled my hubs USB Device Manager etc, but a device is not installed correctly: mass storage controller. It is of course preventing me from accessing the USB and external hard drives. Where can I get the drivers for this if Windows XP does not have? Sure that the key USB is FAT32 (the default format) I went in the properties of the mass storage controller in the Manager of peripheral and copied the device ID. I did a Google search and was surprised to find that it was a card reader. I downloaded the drivers from my manufacturer Web site, and Windows has detected and installed the drivers for the card reader, as well as the mass storage controller. The USB appears in the Explorer, but shows 0 items. I have After the reboot, the USB is not in Windows Explorer, and when I unplug and reinsert an error comes up saying the USB device is not recognized and malfunctioned.

  The solution was to turn off the laptop, remove the power cable and leave it for a few hours, before feeding it back.

  Windows detected and installed the device very well then.

  I don't think that I understand perfectly why he fixed.

• Error "USB device not recognized" but nothing is plugged

  Hi, this problem recently just started to happen, nowhere I can say. Whenever I turn on my computer or it wake up from hibernation, a message from the task bar appears saying "USB device not recognized". However, there is nothing plugged one of my USB ports. I have three USB ports available, and all are empty. I tested all three ports in something by plugging, and all three ports seem to work well. What can I do to get this message to stop appearing? Thanks in advance!

• Is AT200 - possible to connect USB devices?

  Hi all

  I bought last week a Tablet AT200-100 (in Spain), and a few days ago I also bought an adapter for USB cable for it. I've seen (at least that is what I understood) that it is possible to connect devices to the Tablet (as a host).

  Well, I tried with two cables different and two different pills (I went back one and got another), and I can't get it to work.
  I hope you can help, maybe I'm doing something wrong...

  I used a micro USB B (plug) to USB (plug) adapter, and I tried to connect a USB keyboard, mouse and an external hard drive. Everything seems to work, nothing doesn't appear on the screen, and nothing new appears in the file manager. The light devices has never lit at all.

  Is it necessary to install something before? To activate something?
  I use a bad cable?

  Help, please!

  Thanks in advance!

  Hello

  The AT200 seems to be equipped with a USB port of microfiber that support OTG technology.
  Allows you to connect the key USB and HID (keyboard and mouse).
  This port is USB 2.0 compliant.

  To connect a USB (memory flash USB, keyboard or mouse), you must use a cable OTG (USB On-The-Go). The cable must be certified USB ON-THE-GO.
  http://en.Wikipedia.org/wiki/USB_On-the-go

  PS: this Tablet does not support a printer and as I know the operation of the port of USB devices was not confirmed for some USB devices may not work correctly.

• Laptop HP Pavilion dv6 - 3016 s: USB (device not recognized) problems

  Hello

  on my laptop (Pavilion dv6-3016sl, bought in 2010) for a few months the USB connections give many problems with different devices.

  The first issue with the key external communication 3G (ONDA TM201) Internet: the USB key (which has worked for many months) is not recognized. I tried to reinstall the software and drivers (get the latest version from the website of the producer), but it is always unclear correctly.

  The visible in USB Device Manager error message is "cannot start (code 10) machine.

  Recently other USB devices have ceased to be recognized: powered USB Hub (HAMA USB 2.0 Hub 1:4, bus) and the Wired Optical mouse (Logitech).

  It is also not possible to install new USB devices (for example, a device of wireless sync to a cuff of training).

  I've done many controls of Microsoft on the integrity of the system, and I frequently run the Windows Update to be aligned to the latest version of the fix.

  You have any suggestions to analyze/fix this locking problem?

  Thanks in advance,

  Moreno

  I know this may seem a rather harsh to suggest method, but at this point, I suggest backup of important things on your laptop computer to online storage. This is because you can use the USB storage for the moment.

  Once you have done this, it's time to locate your drives support usb recovery and licenses of all other programs that you have installed or recovery.

  Start on the recovery media.

  Use the HP Recovery Manager to perform a factory image recovery which will reinstall the operating system.

  Since you say that the usb ports work under Linux, then reinstalling the operating system Windows needs to solve the problem of usb port that you are experiencing.
