Usb doesnt work

i have a macbook pro 2011 and one of the USB ports doesnt work

I periodically see this on my computer running mavericks and find I can restart (maybe even power down/up) and bring the port back to life. Have you tried this? I was almost thinking of reporting this as a(nother) Mavericks bug but I have no idea if this is just me or if others have the same issue.

hello,
I downgraded hp 15-r101na from win 8.1 to win7 64bit, and got a huge problem, all usb ports doesn't work (although they provide power).
I was unable to update drivers via "Device manager", windows just dont find them.
I tried downloading drivers from http://support.hp.com/us-en/product/HP-15-r100-Notebook-PC-series/7234951/model/7429481/drivers#Z7_M... , but it did not help.
Maby someone could recomend third party drivers, or other solution?

Creative WebCam Vista Plus on USB PCI Card (VIA VT 6212) on Windows ME - doesnt work !!

PC turns off when the Vista Plus WebCam is connected to the USB port on my USB PCI Card
I use a primitive Intel Celeron 300Mhz processor with 64MB RAM on an Intel 440BX-AT Chipset running on Window ME. I recently installed a USB PCI Card (based on the VIA VT 622 chipset) which is a 394/USB 2.0 Combo. The problem is my 'Creative WebCam Vista Plus' doesnt work with it.
After I had installed the drivers on the 'Creative WebCam Vista Plus' CD - that is - without connecting the webcam to my USB PCI card the installation asks me to connect the webcam to the USB port and When I do that the PC just GOES OFF !
It starts up only in SAFE MODE and each time I've got to restore my PC.
How do I get the WebCam connected to my PC ?
Thanks in advance

9hours later and Ive given up. I cant get the Vista 64 Ultimate to work with the Audigy 2Nx usb sound card. Im very angry and very frustrated (not to mention very tired from the 2 late nights Ive spent trying to work it out). Im not a PC-noob, but am only 4days into my Vista ownership................... Im guessing now, after much research, that there will never be a driver that gets these units to work with Vista 64bit. thats pretty weak Creative. However, I dont want to use crappy onboard sound for my gaming.What is the suggestion?Should I be looking at returning this unit, and buying either the X-Fi Xtremegamer?Fatality Pro as?a highend device, or the X-Fi Xtremegamer for $00 less? Or should I be looking at another manufacturer. Would either of these x-fi gamers work with Vista 64bit Ultimate?suggestions please?

How do I install an apple usb SuperDrive with my macbook that already has a superdrive but doesnt work?

I bought a macbook off of a friend but the CD drive to the computer doesnt work and was broke awhile ago. I needed to install some software onto this computer so I bought the Apple USB SuperDrive thinking it would work, but later finding out that it is only compatible with macs that dont have a superdrive built in. An Apple support technician told me that it could be done through a process, but she couldn't help me with. So it would be greatly appreciated if someone can help me with this problem. Thank You!

There is some useful information here about the process mentioned:

Of course you need to be very careful with any use of Terminal.

FATALITY GAMING USB HS-1000 volume control button doesnt work

I have just bought CREATIVE FATALITY GAMING USB HS-1000 headset. Everything is ok, except of volume control button on wire, it just doesnt work. I have installed and updated drivers, nothing helped. I have readed few topic on similar issues, but there wasnt any solution. My OS is winXP SP3.

Have you tested your headset jock or where you plug your headset? It may be coming from that, as you have said you have tested the unit in another pc.

MSI GF4 Ti-4200 doesnt work with WindowsXP

I can't get the MSI display tools to work - it crashes,
the vbios.dll doesnt load, it also crashes.
the tv in doesnt work ,it crashes
the tv out doesnt work ,it crashes.
all the supplied software also crashes "application has encountered an error and cannot continue. sorry for any inconvenience"
the intervideo software (windvr, wincoder, winproducer) and MSI PVI software all crashes as well.
what's the deal with this stuff? ?(
I have a Dual AMD athlon Tyan thunder k7 motherboard,
MSI Ti-4200-VTD video card and MSI tv anywhere card.
is there any resolution for this?

I'm sorry gfilitti if I don't have my system listed, but I thought my question was pretty simple...
Has ANYONE been able to make the InterVideo WinProducer 2 software, that comes with the retail version of the MSI G4Ti4200-VTD64 card, work successfully under the Windows XP Home or Pro operating system?
If the answer is YES, then I will begin investigating why my system can't.
If the answer is NO, then I only ask for other people's recommendations of what software WILL work in place of that. I NEED those functions to work. That's why I paid extra for the VIVO.
All we've heard so far in this thread are NO votes. I would like to see just how widespread this is. If I can find ONE person who claims it works fine on his/her computer under Windows XP, then my NEXT question would be if they had to do anything different to make it run, or was it just a straight install? Did they add the program patch available from the MSI website? See where I'm going with this?

BTW, I would think when investigating a program's FLAT refusal to run, that the MOST important things aren't listed in these signature files. It has to do with what ELSE is running at the same time. Which services are running and which are NOT? What memory resident programs are loaded at boot-up? Any service packs installed? How about any security patches from Microsoft? Which anti-virus software (if any)? Which DirectX version? Personal firewall? Etc., etc.
Granted, the hardware DOES have a factor, but I feel all of these are MORE important factors than the speed or brand of a persons hardware. I look at the signitures more as bragging rights than anything else.
Now, this is just my opinion and may not reflect the feelings of the more sane people around me.

ITunes doesnt work with my iPod!!! Help please!

ok...i have tried to plug my iPod into my computer lately, and iTunes doesnt recongnize that my iPod is plugged in!!! i have pretty much de-bugged the problem...its not any of my USB ports b/c other hardware (digital camera etc...) work in them...and its not the computer...but it could possibly be iTunes. if i delete and re-install my iTunes software do i loose all my songs? and w/out loosing all my songs etc is there anything i can do to fix this?
i have also tried resetting my iPod multiple times, but that doesnt work so...the only other thing i can think that could have happened is: i got an iHome a few months ago, and ever since that i have had the problem...so that could have messed something up...can u help?

Does the text on your iPod show up grey in iTunes? Grey text when you look at the content and lock symbol at the bottom of the screen simply shows that your iPod is set to "automatically update songs and playlists". . If you want to access your iPod directly, play it through your iTunes, connect it to a second computer etc. you just need to change the update method to "Manually manage songs and Playlists" in the iPod preferences. For more detail see this tutorial: Managing Your Songs Manually
One thing to be aware of with manually updating is that the iPod also has to be manually ejected before the "Do Not Disconnect" message will go away. Safely disconnect iPod
For info: iPod 101
The iPod offers three ways to transfer music from your computer. You can select one of the following update modes from the iPod Preferences menu in iTunes (Edit=>Preferences=>'iPod' tab):
1) Automatically update all songs and playlists. This is the default mode, in which your entire music library, including playlists, is automatically synced to your iPod. If the music library on your computer exceeds the iPod storage capacity, you are prompted to select a different update method.
2) Automatically update selected playlists only. With this option, iTunes automatically copies the playlists you have selected to the iPod when you connect it to the computer.
3) Manually manage songs and playlists. You can also choose to transfer music to the iPod manually. This allows you to drag and drop individual songs and playlists from iTunes to the iPod.

Gf4MX440-VTP TV-Out doesnt work.

I've just buyed a dual gf4 mx440 with 64Mb and TV-Out, TV-In.
When I installed it I began working with two monitors witout problems, but when I've tried to connect de TV-Out, it doesnt word.
I've checked a hundred times the cable connecting, and it's ok because with my old graphic card I could.
I tried to upgrade the BIOS with an unofficial version and it didn't work, I downdated to the original version of BIOS again.
The graphic card detects the TV because it enables the TV-Out option in the configuration, but when I enable it I get a strange screen of one color on TV. The TV get's of a color brown or orange or something like that and I can't see nothing.
I've selected my country format (Pal/B, Pal/G). I've also tried all other formats whitout any result.
I'm running Windows 2000 Sp3
My motherboard is a DFI AD70-SC (With AGP 4x)
AMD Athlon XP 1.500
512Mb DDR RAM
I've tried all but it doesnt work.
Thank you very much.

Dunno if this thread is still going, but I figured why not
Well, I bought the GF4-mx440 VTP (8866) back in october, but haven't actually gotten around to testing it until last night, and I ran into the same issues.
For reference, the drivers on my cd are 30.00.
It was quite frustrating, but I did a ton of research and here is what I was able to find out. THis information isn't terribly organized, but bear with me because it's hopefully useful
TV-out on nvidia cards is not as simple as some may say. (Ie. all those who say nvidia has way better drivers than ati ).
Different detonator versions have WIDELY varying tvout support. In Some versions it works, some it works well, some it works poorly and others it doesn't work at all. Quite shocking, but sadly this is true.
Bits of info about the MSI-mx440 vtp itself. The tv out is based on a Seperate chip, the Phillips 7108. This chip handles the tv in and out features. (Geforce4 chips have themselves an "on chip" solution for tvout. But typically when manufactures use a Video In chip, you let that chip handle video out also).
Regarding the 440's bios. There is only one version (as listed through the live update running win9x). HOWEVER there are issues with this card and WinXP, to which the fix is to apply a bios update. I have not tried liveupdate on winxp (I run 98se), but I think that this bios update is only available upon special request to MSI. I'm not sure how it affects the situation(s) under win9x, but supposedly it fixes some winxp issues. (I will be installing XP in a dual boot config shortly, so I'l know for sure soon ). So according to the MSI support FAQ's, there is a bios update to address issues in winXP, that you can only get through special request (assuming you have winxp). I am not sure what the affects would be on win9x system, but since I am giong to dual boot soon, I'll probably have to apply the new bios and find out.
Okay, so how to find out if it's a software (driver) problem, or if it's hardware (a broken card that you can return). Here's what you do:
Unplug all monitors (vga connections) and plug in the TV out (I dont' have any s-vidoe tv's, so I just use the composite (RCA) jack) to a tv, and make sure the tv is on. Now boot your computer.
If you get output to the tv (usually the post info from the motherboard, followed by the win98 startup screen) this means your hardware works fine. (This is what happened to me). Strangely, it made it all the way into windows (on the tv), but typically what happens is that once windows loads you end up with the messed up pinkish brown screen. (I've never been able to have it boot into windows on the tv since then, heh).
SO if you do get picture during startup (before the os loads) then it means your card is fine, and it's a driver issue.
*Note: One thing I've noticed is that your tv-output is affected by which VGA out port you put your monitor on. For me, when booting with both connected (vga and tvout) if it's plugged into one socket, I see both monitor and tv, if it's plugged into the other socket, I don't see tv at boot. Not a big issue, but worth noting*
Okay, so now if you did see otuput on the tv during boot (before windows), you know your hardware is working. So you have to find a driver version that works for you. I'm going to list my own experiences.
MY cd came with the 30.00 MSI drivers. These gave me that icky pinkish brown flickering screen. Tv-out didnt' work with them. Tried the 31.00 MSI drivers, same thing. This was odd I thought, as the two most recent MSI drivers didn't work. So I tried the MSI 28.90 drivers, same thing with them too.
Finally I tried the MSI 27.20 drivers, and voilla, tv out worked! I was able to extend the desktop, and clone it, was even able to tape a downloaded episode of 24 on my vcr .
Of course using year old drivers is less than ideal (especially for 3d gamming). However, these are the ONLY MSI drivers that have tvout working.
I decided to move on to the nvidia detonator reference drivers, ideally you'd stick with the manufacture MSI, but what can you do. Here is what I have found so far:
27.20 MSI - Works with tv out
27.20 Nvidia - Works with tv out
27.30 Nvidia - This one is interesting, tv out works in extended desktop mode. BUT there is no tab in the options for cloning (the 'nview' tab is missing). So you can't clone, or overlay, only the extended desktop. So it's an "extended desktop only" driver.
27.42 Nvidia - Works with tv out (works same as 27.20s)
28.90 MSI - NO tv out
30.00 MSI - No tv out
31.00 MSI - No tv out
30.82 - Most resent 41.09 Nvidia - Tried them all, no tv out for any of them.
I have yet to try all the 28-29 nvidia reference drivers, so dunno if tvout works with them.
So what does this all mean? FIrst off, check if your cards hardware works (boot only with tv on and tvout connected, NO VGA). If your hardware works, then you have to find drivers that work with tvout. Give the ones that worked for me a shot, see if they work for you. (I typically plug in my vga and tvout at same time, so a see the POST in BOTH of them. Boot the computer with everything on, and then go to the settings and try to enable tvout).
This situation is less than ideal of course. It looks like you have to pick your drivers based on 3d performance, or tvout. But not both! Either use the most recent drivers for the best 3d support (but no tvout!), or 1yr old drivers for tv-out, but not the best 3d support. I'm an avid gamer personally, so this situation sucks.
What I find odd, is that MSI's own drivers (28.90, 30.00, 31.00) have these issues. They are privy to the peculiarities of the MSI cards, so they should be able to address it.
What the pattern (some drivers work, others don't) suggests to me is that MSI cards aren't fully compatible with the reference design. Possibly an issue with the bios.
I will try and get a hold of the bios update for the WinXp issue, and see how that affects the situation in win98se.
Hopefully this was helpful

Fans going crazy, airport doesnt work and nor does iSight

Hi
I have a 13 inch Macbook Pro, late 2010 model, 2.4 ghz, 4gb ram, so on, so forth
Just had the Logic board done as it died (intermittantly, then completely), and now the fans go crazy at most opportunities, sometimes Airport doesnt fire up (cures with a restart) and iSight doesnt work at all. It goes really slowly when the fans are going nuts. This is only using Chrome..
Any ideas? I'm falling out of love with this computer.

You have a real problem to deal with. I would recommend you download a utility like Snow Leopard Cache Cleaner and clear all user, system, and font caches. Then the following:
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. If you Quit the installer at this point the computer will restart.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Let's see if that helps you out.
