• Unknown device: Windows has stopped this device because it has reported problems (Code 43).

  I have Windows 7 Ultimate. Recently an unknown device keeps popping up in the device manager every time that I start to win. It is reported the location is in the front USB hub, but I haven't changed it anything lately. The device status says "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall or disable it but it will get picked up again the next time that I reboot. All other usb devices (mouse, keyboard, webcam, UPS APC, external hard drive, printer) work very well. How can I get rid of this nuisance so that it is not reappear?

  If the problem coincided with connecting the inverter APC that may indicate the problem is with the inverter.

  Somewhat similar situation discussed in the following link:

  http://www.velocityreviews.com/forums/t527369-APC-ups-USB-as-unknown-device.html

  Your situation sounds similar as "Information system" leading the 'problem of the device' has an error Code "this device is working properly" but still "unknown device".

  I would say to detach from the APC UPS of the computer and uninstall any software related.

  Restart the computer and see if the "Unknown device" problem resolves.

• S230u Windows 7 unknown device

  My company recently bought a ThinkPad S230u for use on the ground, time management and others, to help relieve the duties of our managers. However, my company only supports up to Windows 7, so it was my job to make this thing work on Windows 7. I managed to compile almost all drivers for the machine with hardware ID and various research, which I'll be happy to help provide if anyone needs them. However, there are still two items in my device manager I have not managed to solve yet, and I do not have any progress. Any help would be appreciated.

  Two unknown devices have hardware ID:

  ACPI\MSFT9000

  and

  ACPI\MSFT9001

  My guess is that it's the battery, but I already have the lenovo power management software installed with no luck. If anyone can help me to get it working on Windows 7 x 64 (Professional), I would be very grateful. Thank you!

  As a note, if anyone needs help for other drivers together for a similar project, I'd be happy to help you. I already did the work, so no need to repeat the process if you don't have to.

• 4 "other unknown devices" in Device Manager. Windows 7 RTM 64 dv7 1450

  Just bought a computer HP dv7-1450 laptop with AMD Turion X 2 64 processors. Installed Windows 7 RTM 64 and everything seems to work except there are 4 unknown "other devices" listed in Device Manager. The 4 devices are:

  -System base unit (x 3)

  -Unknown Device (x 1)

  I have no idea what are these devices. I tried looking for drivers for chipset on the AMD and HP Web site without result. But I do not know if these are the associated chipsets. One of the devices would be the disk fall sensor hard (it does not appear in the device no matter where Manager)?

  Unfortunately on the HP site, there are not many downloads of drivers available for the 64-bit (Vista). I know that Windows 7 64 drivers won't be available until in October, but if there are not any available Vista drivers either, I expect to see all the drivers for Windows 7?

  The most important thing for me is just to know what are these "other devices" 4 and get the drivers installed.

  Thanks in advance!

• Unknown devices in device Windows 7 Manager - dv7-2170us

  I have a laptop dv7-2170us.

  I did a clean install with Windows 7 Home Premium 64-bit.

  I used the drivers for this model of laptop on HP's site.

  I get a few unknown devices in Device Manager.

  I tried to uninstall the device and re - install to allow Windows to re - detect but no drivers are found.  See the pictures below, what devices could they maybe refer to?

  I have all the necessary drivers load that I know and I installed a driver who looked valid on the site of HP drivers.

  

  

  EDIT: Everything works!  Thanks for the tip of Daniel.  I googled how to identify the ID of material and is here with this site http://www.pcidatabase.com/ , punch in the device id and bam, it IS the card reader.  Weird because it worked perfectly.  But I downloaded the driver even re-installed and this solved the problem.

  =============================================

  I tried the Intel Chipset utility, did not work. However, here is the hardware id:

  

  

  

  If you look closely, you will notice that each of these devices are in fact different.
