Windows 7 Blue Screen of Death minidump analysis request

Greetings wise wizards of EE:

I'm helping a friend with an HP Pavilion Windows 7 laptop that just recently started producing the dreaded blue screen of death. The BSOD does not appear often, though it does appear randomly. I was able to copy two minidump files (dated 9/12/14), which I attach to this inquiry.

I now ask for you wise wizards to analyze the attached minidumps, so that I can solve her BSOD issue. Though I am grateful for all responses, I would ask specifically for an analysis of these minidumps from an expert who can decipher them, rather than just general advice or BSOD utility links, so that I tackle my friend's solution directly.

Many thanks in advance,

Zovoth

Zovoth  the 2nd dump says :  _IMAGE_usbhub.sys  , and  DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.


so it is an external device, connected over usb - is this a disk drive, in an external case?  it seems to have a power problem
does it have it's own power supply?  if not use a powered usb hub
otherwise, you may need to replace the case (with it's PS)

G'day Zovoth
I have diagnosed your Dump files with an error DRIVER_POWER_STATE_FAILURE (9f) with a bug check code of 9F. This means that a device object has been blocking an Irp for too long a time. The faulting driver is btfilter.sys.
Try to download and install the latest btfilter.sys, which is the Atheros Bluetooth Driver Package from the manufacturer’s website.
http://atheros-communications.drivers.informer.com/bluetooth/

Plug in your transceiver, restart the computer.
Use your computer normally to test by connecting a Bluetooth device.

Or as the Microsoft Bluetooth package is already installed, disable the Atheros Bluetooth Driver from Device Manager, restart the computer. Use your computer normally to test by connecting a Bluetooth device.

Your Bugcheck analysis for the minidump file:
DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time (usually 10 minutes).
Arguments:

Greetings Nobus & Rob Miners:

Many thanks for your rapid and helpful replies regarding your analysis of the minidump files. I spoke with my friend about USB and bluetooth devices, to which she stated that the only USB device she regularly connects is an older iPhone. She has just recently replaced it with a newer Android, so I am hopeful that the BSOD is behind her. Based on your analysis, we shall keep an eye on her external device useage if the dreaded BSOD reappears.

Thanks again and may the wind be at your back,

Zovoth
