How to update webcam driver?

I've ArchLinux installed with v4l-utils 0.8.8-1 and gspca_zc3xx webcam driver v2.13.0 . The driver is installed as a kernel module, and I can detail it with modinfo gspca_zc3xx command. This driver version is now outdated, and it doesn't support correctly Auto Gain and Exposure controls in my webcam Logitech Quickcam Communicate STX. On the developer's site in Webcam GSPCA driver V4L version 2 section there is an updated version of this driver v2.15.18, and I found the thread gspca_zc3xx possible options in Mint lxde 12? claiming the above issues were fixed in it.
Can someone explain with code examples, how to update the webcam driver in my ArchLinux installation step by step? Webcam Setup ArchLinux Wiki lists various drivers, but come very short on explaining how to install them or update already installed driver. Is there a Wiki on how to install or update any device drivers in ArchLinux?

I think you should since the kernel owns the files. Also, the file you linked is beta, so it is likely no one will,add this to the official package for you. What I don't know is how best to handle this.
1) rebuild the Linux package except manually delete those files for the build prior to packaging.
Or
2) make a new PKGBUILD for just this new driver and somehow handle the file conflicts outside of pacman... Not recommended in my mind.
Perhaps someone else can offer and alternative solution but for now I think that option 1 is your best bet.

Hi,
I am using my Late 2012 rMBP also in bootcamp with windows 7 64-bit
Often I see a popup from the NVidia Control Panel saying that a new update is available. Most of the time, the update adds new game profiles and such... I only use my Mac for CAD. But sometimes they also fix bugs or improve routines...
I know I am "safe" to ignore these messages.
But is it also "not recommended" (or even "dangerous") to install these updated drivers?
Probably, the included driver in the bootcamp driver pack is tweaked for these MBPs.... but is it?
Regards,

How to update NIDAQmx driver in Labview RT?

Dear members,
I have a problem to make my NI PCI 6289 card working in Labview RT.
Namely when I run the self test appears an error number -88716.
The screenshot says that the NIDAQmx drivers on the host and on the target are different.
It suggests to update the driver to correct the error.
Now I have checked. On the host I have the NIDAQmx8.5.1f2 driver on the RT target the NIDAQmx8.5.1.
The question I want to ask is. How can I update the driver on the RT target to the other version?
Since I have installed the RT system just yesterday I can't imagine that I have done some updates on the host which are not done on the target.
Someone has an idea how to override the error?
Thanks
Principiant
Solved!

The NI support solved my problem here is the link with the solution.
http://digital.ni.com/public.nsf/allkb/A47734CC1E03922186257435004D0C49?OpenDocument
In the download page, just download the first link NIDAQmx 8.7.1 not the runtimes at the end of the page.
Thanks for the help .

Please advise how to update driver for W7 as it is not available on the HP site.

Hi:
Did you try the Vista driver? Normally they work fine for W7.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-69143-1&cc=us&dlc=en&lc=en&...=
Another thing you can try is to be connected to the internet. Click on the audio controller in the device manager. Click on the Driver tab. Click on Update Driver and select the automatic search.
Sometimes W7 will pull down a driver from the Windows Update site.
If the above 2 suggestions don't work, try this driver which seems to be the same as the Vista one, but for Windows 7.

How to Update the driver of your graphics card

When I open Photoshop CC, I get this message:
"3D features require a minimum of 512MB of vRAM. Photoshop has detected less than that on your system. Updating the driver of your graphics card may resolve the issue."
I went to the website they recommended but found nothing about this. How can I determine if this is the problem? How do I find out how much vRAM I have? How do I update the driver of my graphics card?

You cannot upgrade the GPU except by buying a newer model with a better GPU. Normally, with shared RAM the GPU will have a maximum of 384 MBs of VRAM with 4 GBs of installed RAM. That will increase by about 128 MBs per 2 GBs of additional installed RAM.

How can I know the version of existing installed hotkey driver? Where does it hide?
When I update the hotkey driver, do I need to uninstall the existing installed one first?

How to update usb driver...

I've got a MS-6390 and am running Window 2000 Pro. I am trying to get my digital camera to connect, and their support tells me I need to update my usb drivers. My multiple attempts all end in miserable failure as far as I can tell. I'm checking in the device manager and looking at the properties for "VIA USB Universal Host Controller" -- on the driver tab I see "Driver Provider: Microsoft Driver Date: 11/14/1999 Driver version: 5.0.2183.1", which suggests to me that the update I just did was ignored. Can someone *please* give me a clue as to what I need to do????

Thanks, but I've had sp3 for a while now. Nikon support has disowned me and won't talk to me anymore until I have a "supported" usb driver. I broke down last night and bought a cheap plastic compact card flash reader and everything works -- it even auto-starts the Nikon software when I pop in the cf card!
So I have a useable work-around, but I am still bugged that I can't get the update working for this motherboard/os. I don't want to give up on that just yet. I hate it when something that should work, doesn't! X(

How to update my driver

i am user for hp deskjet 1515 for hp deskjet 1510 series version 30.0 can upgrade the version to 32.2 without uninstall the old version please reply in the fast time

Hello Nxccraft,
Welcome to the HP Forums.
I see that you would like to upgrade the driver and software to the Version32.2.
You can do the upgrade but you will have to uninstall the printer from the computer and disconnect the usb cable from the printer and the computer before you can reinstall with the HP Deskjet 1510 e-All-in-One Printer series Full Feature Software and Drivers.
Let me know if you have any other questions or concerns.

Satellite A200 - WebCam issue - webcam drives has failed

Hi,
I need some help regarding the integrated webcam of my Satellite A200.
Everytime I start the laptop I keep receiving a message saying that the webcam drives has failed and I have to restart the computer, but the problem persists.
I have downloaded an updated webcam driver, but nothing.
Can anyone give me an idea of what is going on?
Thanks!

Ok - I've had the same problem:
"Everytime I start the laptop I keep receiving a message saying that the webcam driver has failed to load and I have to restart the computer"
Same when trying to update driver from Toshiba site, same when rolled back / uninstalled drivers, then re-installed default drivers. Nothing worked.
Sorry - but the solution that worked for me wasn't easy.
I had to disassemble the laptop to take a look - fix something else ( wireless on/off switch had broken / jammed in off position - lugs had snapped on back of the slider switch on the case, but no problems, I just left it in "on" position, as wireless can be switched off in software anyway). I decided as I'd got that far already, to pull the laptop completely apart and clean it out properly.
There's a shielded cable running from the webcam in the lid, though to a small white socket on the motherboard, accessible under the keyboard, next to the wireless board.
I was disconnecting various other cables etc, and came across this one disconnected, and couldn't remember disconnecting it myself. Hmmmm...
Anyway, I connected it back up on reassembly, it pushes in to the socket and seems seated, but needs an extra little push to "snap" securely in place.
My guess is that some of these haven't been seated properly ex-factory. They probably work just fine, until perhaps through repeated flex on the back of the keyboard when typing, or opening and closing the lid, the connector falls out of the socket.
Anyway - my webcam works again now. (using Vista SPII and all current updates, but in my case that's not relevant, as it was NOT a software or driver issue).
There's instructions (with pictures) for disassembling the A200 on the net - use google to find them. You don't need to pull it completely apart, just to the point where you can get the keyboard out, then you can access the connector.
