HP Probook 470 G0 - Biometric device (driver) problem

Hello,
I have a problem with biometric device, I can't find biometric in device manager. Does anyone know how can i fix it? I installed driver (Validity Sensor) but nothing happens when i enter in device manager. Does anyone know how can i enable biometric? Thats the whole problem I think, there is no biometrics in device manager. Is that problem with BIOS, can i enable it there or what? I use Win 7, 64-bit.
Thanks in advance,
Aleksandar Sretenovic

Can anyone help me, please???

Thunderbolt device driver problem

I have a W540 and running Windows 7 64 bits - and brought a WD My Passport Pro Thunderbolt HDD. I know it is for Macs - but, I was thinking of reformating the HDD into NTFS once I can get the HDD to mount into Windows. The Thunderbolt Devices display tells me -
Thunderbolt Port 1 *-> Western Digital, My Passport Pro.
Unfortunately, I have a problem with "Standard AHCI 1.0 Serial ATA Controller" driver - gave me Code 12.
Does anybody knows of a replacement device driver to get this HDD to work? Or recommend an equivalent portable HDD (of at least 4TB) that works with W540 Thunderbolt port.
Thanks... WTS

Update - I think a more fundamental issue is this ...
Does the W540 BIOS support Thunderbolt hard-disks? I ask this - because I observe this ... when a Thunderbolt hard-disk is plugged in AND I reboot the computer, it hangs at the BIOS initialisation stage. Only when I remove the Thunderbolt drive, then the machine can boot up.
Also I noticed there is NO option in the BIOS for Thunderbolt - only USB.

Solaris 10 GA and 64 bit Pentium Processor. Device Driver Problem

We have a Dell Poweredge SC420 with 3.4 GHz Pentium 4 (EMT64)
it also has 300Gb SCSI disk and 2 Gb Ram.
By default this machine tried to boot with the 64 bit kernel then could not load the CADP driver (SCSI CARD). We forced the Kernel to 32 bit by changing the BOOT_FILE from /kernel/AMD64/unix to /kernel/unix.
The machine is now booted but we are having problems with our PCI device. The device is a DMA Bus master and works fine on another SC420 which has a 2.8GHz Non-64 bit processor running the same release of Solaris. The device driver fails in strategy when we try to bind the dma buffer,(ddi_dma_buf_bind_handle) returning DDI_DMA_TOOBIG when the cookie count is > 1.
The machine appears to function apart from our device although we have suffered some kernel panics. We cannot ascertain if other devices are performing DMA successfully but must assume that they are.
Anybody got any ideas, Has anyone else got this processor working?

My bad. The memory per guest domain is 1GB. Se the Section 1 (NEW) - Hardware http://wikis.sun.com/display/SolarisLogicalDomains/LDoms%20Community%20Cookbook

Unable to Sync Centro with Vista 32; device driver problem

I currently sync my Palm Centro (Verizon) to my Desktop Computer running Windows XP and Palm Desktop 6.2.2 with no problem. I am trying to move everything to an HP Notebook running Vista Business 32 bit. I disabled Norton Internet Security and loaded Palm 6.2.2 on the notebook but was unable to sync. Error message on the Palm said “The connection between your handheld computer and the desktop could not be established. Please check your setup and try again”. On the notebook the Palm handheld device driver has a “?” besides it. I tried doing a clean uninstall and reloaded Palm Desktop 6.2.2, but it still gives me the same error message. I tried looking for an updated device driver, uninstalling and reinstalling the device driver didn’t help either. Palm Support was unable to fix the problem. I then tried restoring the notebook to the factory condition, and reinstalled Palm Desktop; same error message; Palm device driver still has a “?”. I called HP Tech support. They had me update the Bios and update Vista to Service Pack 2. Still has the same problem. This is driving me crazy! Any ideas???
Post relates to: Centro (Verizon)

The system doesn't allow me to browse to PalmUSBD.inf or any other specific file name. It only allows me to browse to the subfolder USB_Driver. When I tried to key in the file name C:\Program Files\Palm\USB_Driver\PalmUSBD.inf and click next I'm told "The location you specified does not exist or cannot be reached."
I tried uninstalling the driver, then reconnecting to another USB port; driver seemed to install successfully, but then still has "?" and doesn't work. I am not using a USB Hub.

WinXP reboots caused by a device driver problem??

Hi All the experts there,
I recently bought and installed a MSI 865GM2-LS Motherboard. However, after I installed WinXP, as each time I get onto the web, system reboots and telling me it's caused by a device driver. I installed every device drivers provided in the installation disk. Is there sth wrong with the hardware of just software problem?
This is really wierd because I've tried WindowsME with exact same hardwares attached and device drivers installed, it works perfectly!
Please Help!
MSI 865gm2-ls
P4 2.6G 800 FSB
Kingmax 512MB Memory
Seagate 120G HD
Pioneer DVD-RW A106
WinXP Home/Professional

Sorry, I forgot to mention that there wasn't any problems AT ALL when I use the exact cable modem with another computer that has WinXP installed!! I don't think it's the problem of the modem driver.
Maybe BIOS configuration problems? Then, what is it? I have gone through numerous times and I can't think of anything I might be mistaken.

MTP USB Device Driver problem

Hi Guys
I currently have an iPhone 5S and I am trying to connect it to my Windows 8.1 Computer so that it appears as Mass Storage, enabling me to back up photos and videos. I noticed int the Device manager that the "MTP USB Device" has an esclamation mark on it and it states that the driver was unable to verify the digital signiture of the device and cannot be used (Code 52)
I have tried various methods to try and resolve this issue but I have had no success.
E.G...
https://discussions.apple.com/thread/3153566?tstart=0
https://discussions.apple.com/message/16322708#16322708
https://discussions.apple.com/message/22972618#22972618
and various other methods.
I Contacted Apple support and Microsoft Support but they were unable to help me. The device was working until a week ago and suddenly stopped showing up as a Mass Storage device. It is visable in iTunes and can be used to USB tether, but not USB Storage because of this MTP USB Device error.
Has anyone got a fix for this that actually works?
Your assistance greatly appreciated.
Chris

Update.
I have found out that the driver file for MTP USB Device is the file winusb.sys.
The problem is that it is not digitally signed and windows 8.1 can not verify it's signiture. This is why there is an esclamation mark on the device in device manager.
I have tried various procedures to fix the problem but none have been successful yet!
If the driver file was digitally signed, the driver would be fine.
The search goes on..

Bluescreen - Software Device Driver Problem

The problem also occurs with safari beta (3.0.4) and firefox (2.0.0.9). The Bluescreen is reproducible on both browsers with some pages of apple.com (those with Quicktime videos). After uninstalling Quicktime i saw a picture of the XMas-Add on the start page (with the Download Quicktime link). (Quicktime v 7.3)

Hi!
Its not easy to say what is wrong.
First of all, which notebook do you have exactly?
In your position, I would first check the RAM. There are some special tools and I do this always with Memtest86.
You can download an ISO image to burn it on a CD from [www.memtest86.com]
Boot from CD and test your RAM, maybe you will get some errors.
You can also reinstall Windows with the recovery disk. It could be a software or driver issue.
If you have more questions, I will try to help you.
Bye

NI device driver locations for upgrading labview to 64-bit

There is a section in the NI LabVIEW 2012 SPI (64-bit) download where it prompts you for the location of the NI Device Drivers. Unfortunately, I cannot get a hold of the original CDs for a while, so I cannot see where they default to. Does anyone know where these drivers default to? Alternatively, what should I search for if I want to find these device drivers?

Probook 470 windows 8.1 upgrade to windows 10, any driver compatible issue?

Probook 470 windows 8.1 upgrade to windows 10, any driver compatible issue?

Hi,
First I assume there is a bluetooth module inside your computer.
If so please test to reinstall its driver. To get a driver for the device, you need to know the brand and model of your computer or your motherboard.
Generally computer manufacturers will provide all drivers for their computers on their website. Search with your computer model on manufacturer's website could help you get a proper driver. If failed, search your motherboard from its manufacturer instead
will also help.
After that, uninstall your bluetooth module from Device Manager and install the driver you just downloaded, reboot to see the result.
Please remember to mark the replies as answers if they help and un-mark them if they provide no help. If you have feedback for TechNet Support, contact [email protected]

Problem with a DDI Device driver for Solaris 8 and 9 on a Sun-Blade-1500

The problem has to do with dma allocated memory and the little-endian format.
When I copy blocks bigger than 256 bytes to the dma memory, using a uiomove() or bcopy(), the data after the first 32 bytes is swapped around over 8 bytes.
The bcopy from a driver (stack) buffer into the dma virtual memory has the same affect.
So it has to do with the kernel dma allocated memory and the endianess.
When I set the byte order to big-endian inside the ddi_device_acc_attr the data seems to be alright, also with bigger transfer sizes.
My device however needs the little-endian format.
I have the same the same device driver running without any errors on a Sun Blade-150 Solaris 8 for a long time now.
Can somebody please advise me?

PCI Memory card.
Problem: When driver moves more then 40 bytes via PIO from a PCI device memory card, the long words are swapped starting at 40 byte transfer size and greater.
device memory description:
static ddi_device_acc_attr_t sdram_access_attr =
DDI_DEVICE_ATTR_V0, /* Boilerplate value */
DDI_STRUCTURE_LE_ACC,
DDI_STRICTORDER_ACC /* Don't reorder accesses */
The user application does a read call, which goes to xxread. xxread calls physio( xxstrategy, bp, dev, B_READ, xxminphys, uio );
In xxstrategy the transfer is done using
ddi_mem_rep_get8(ucb->ucb_sdram_accHndl,
(uint8_t*) kaddr,
(uint8_t*) raddr,
(size_t) bp->b_resid),
(uint_t) DDI_DEV_AUTOINCR );
PCI Device memory is loaded with incrementing address (8bit), 0,1,2... This is confirmed using a PCI Bus Analyzer.
A read of 36 bytes or less returns:
03 02 01 00 07 06 05 04 ...
A read of 40 bytes returns:
07 06 05 04 03 02 01 00 ...
If I peek 1 byte at a time using ddi_get8(ucb->ucb_sdram_accHndl, ...) I get
00 01 02 03 04 05 06 07
Why are the long words swapped starting at 40 byte transfer size and greater?

I'm not sure I clearly understand the problem. Are you saying that some 3825s are not being discovered by Common Services Discovery? If so, are they showing up as unreachable, or are they not showing up at all in the Discovery reports?
