Stream 7 Kionix Sensors and Auto-rotation

[JohnMurray]

Hi,
I have two Stream 7 5701na tablets, both of which were running Windows 8.1.  I've carried out a clean install of Windows 10 on both.  The 'Sensor I/O Devices' section within Device Manager shows the Accelerometer device is installed and functional.  The 'Sensors' section shows the 'Kionix Sensor Fusion' device, but this device is flagged with an exclamation mark, and the device status advises that the 'Device failed to start, Error 10'.

I have tried the original retail build of Windows 10 Pro N, and the latest release Version 1511.  I have also tried the Windows 8.1 and Windows 10 drivers from the HP web site.  I have tried various downloads of the individual drivers (inf25 and inf24), and installing the devices manually as legacy hardware.  Even when the devices appear to install correctly, the 'Kionix Fusion Sensor' device stops with the Error 10, typically within a few minutes.  And I've tried all of the combinations on both tablets, just in case one was faulty.  Both tablets were rotating properly while running Windows 8.1.

Everything else is working as expected, including tablet and desktop modes, and the Windows button, which switches between task view and the desktop.  But within Control Panel -> Display Settings, and within 'All Settings -> Devices -> Display', there is no drop-down or toggle for auto-rotate.

I've installed and re-installed the OS at least a dozen times, trying different driver combinations in different orders, but the Fusion Sensor will simply not stay enabled.  Has anyone else had the same issue?  Windows 10 is better suited to the tablet, and I'd be disappointed to go back to Windows 8.1.

Thanks.

Hi, I have a Stream 7 with Windows 10 and have not had this problem, you probably already installed the Windows 10 chipset driver after the fresh install and searched the forum?  There are quite a few related threads like this one.

Yes, I've looked through that post, and pretty much every other Stream 7 post on the forums.  I've tried the Kionix driver before and after the chipset drivers (both the Windows 8.1 version, and the Windows 10 version).  After installing the chipset drivers, there is a single unknown device left over, the Accelerometer device, which installs itself to the 'Sensor I/O Devices' when I install the G-Sensor Enabling driver.  The issue is that the Kionix Fusion Sensor appears to install, but immediately flags itself with an exclamation mark, and reports the Error 10, couldn't start device message.  I've unistalled the device and the driver, and re-installed with the same result.  I've even installed both devices manually, the Sensor I/O from the 'Update Driver' tab, and the Sensor from add legacy devices.  The outcome is the same, in that the sensor waits perhaps a minute or so, and marks itself as unable to start.  I'm pretty sure the issue isn't due to faulty hardware, as auto-rotation was available on both tablets when they were running Windows 8.1.

Some other posts have mention that there should be two entries under the Sensors tab in device manager, the Kionix Fusion Sensor and the Sdo Sensor V2.  I've installed both of these as legacy hardware, then tried an on-line check of the drivers, which were both reported as being up to date.  The auto-rotate option isn't available, and then two minutes later, the Fusion Sensor and Sdo Sensor are suddenly flagged with Error 10, cannot start device.

The issue is that your auto-rotate does not work on either Stream 7?  I just checked mine and it is working okay.  I have the original Windows 10 final release installed.  I did a clean install, instructions are here. 

Did you update the BIOS to the latest version?  There was a fix for the auto-rotate recently.

If you haven't already, maybe you could try another fresh install of Windows 10, install the chipset driver, reboot, and then install the rest of the drivers.

Looking at my Device Manager currently:

• Sensor I/O Devices

1. Kionix KXCJ9 Accelerometer SP8

• Sensors

1. Kionix Sensor Fusion Device
2. Sdo Sensor V2

The latest BIOS is installed, and I've tried a clean install of both the original retail release of Windows 10 Pro N, and the latest release Version 1511, both from MSDN.  I've installed the OS, then the Intel Driver package (Win 8.1, then re-installed the OS and tried again with the Win 10 Intel package), then restarted, then installed the Sensor Enabling package.  The Kionix KXCJ9 Accelerometer SPB is then created under Sensor I/O, and the Kionix Sensor Fusion Device is cretaed under Sensors.  The Simple Device Orientation Sensor does not appear, and has to be added manually as a legacy device.  If the KXCJ9 Accelerometer SPB device is added successfully, but the Sensor Fusion Device is added but not successfully started, then perhaps this implies a driver issue?  Regardless of the OS version (Retail or Version 1511), the Intel and Kionix driver packages (Windows 8.1 or Windows 10), or individual drivers used (from Kionix, or various other packages), the Fusion Sensor appears to install, but immediately stops with the Error 10, and the SDO sensor will only appear if added manually as a legacy device.

I just noticed that the Intel Chipset, Graphics, Camera and Audio Driver Pack is only available under Windows 8.1, I don't remember that being the case before.  I believe there was a Windows 10 version when I did my fresh install of Windows 10 to the Stream 7, otherwise I would have noted it in my instructions.   I am wondering if that might be the issue.  There has been a problem with drivers disappearing and reappearing on the hp.com site since the Stream tablets were introduced unfortunately.

UPDATE:  Examining the files from my Windows 10 chipset driver and the Windows 8.1 driver, they appear to be the same so that might not be the issue.  Both say: "Intel MRD7 Driver Package PR1 Release - WW35 " and the datestamp on some of the driver files I checked appear to be the same.

Both package sets were available on the driver download page.

The G-Sensor Enabling Driver seems to be at fault.  It configures and enables the KXCJ9 Accelerometer, and it finds the Sensor Fusion Device, but can't enable it.  And it doesn't seem to find/add the Sdo Sensor V2.  I'll give it all one more try with the Windows 10 drivers, this time with the OTG cable unplugged, just in case the keyboard and/or mouse is perhaps causing the other devices to fail to register.

Turned out to be the 'N' version of Win 10.  The non 'N' version supports the Kionix driver, while the 'N' version apparently does not.  As far as I can make out, the 'N' version doesn't install the required driver update framework(s).  The driver appears to run through all of the options, but doesn't actually install the driver properly.  With a non 'N' version of Win 10, the driver install takes approx. 10 seconds, the driver framework portion doesn't appear to be triggered, and the package successfully installs/enables the sensor devices.  If you're looking to install Win 10 Pro, remember to insert EI.cfg and PID.txt files in to your USB image, to override the Win 8.1 Home activation key that's burned into the BIOS.
