3gs not being recognized by the computer

I am having issues with my 3gs. My computer won't recognize my 3gs

The key bit of information here is that one iPhone works on the computer in question and another does not. So it is unlikely that AMDS is not running or there is a driver problem; if either of these was the problem neither phone would be recognized in iTunes.
Unfortunately, I don't have an answer either. Except to verify that both iPhones (the one that works and the one that doesn't) use the same cable and the same USB port.
Also, are the two iPhones the same model and same iOS version?

My iPad is not being recognized by the computer, therefore, cannot sync. It charges when plugged to the wall, but not when pugged to iMac.

My iPad is not being recognized by the computer, therefore, cannot sync. It charges when plugged to the wall, but not when pugged to iMac.

Most common culprits include the cable. Try swapping it out for a different one.. or not having the most recent version of itunes. I once even solved this problem by shutting down the computer for 2 minutes. (the longer the better), with the ipad plugged in. starting it up... then itunes recognizes it, launches, and syncs.
Apple has a troubleshooting assistant on this topic:
http://www.apple.com/support/ipad/assistant/itunes/
It will advise you to reboot. I recommend shutting down instead.

P.S The ipad should charge when asleep and plugged into your Mac. The charging behavior is normal. There isn't enough power out the USB ports to charge the ipad while it is on on some older Macs and nearly all PCs.

TS3850 I am using a Sony HBR -VLU camera to import into Final Cut 10. Plugging into an I MAc that doesn't have a firewire port. The camera is not being recognized by the computer. The camera is set to play tape too. Why is camera not recognized?

I am trying to import from the camera into an I-MAC. I'm told the I-mac does not have the firewire port, but has thunderbolt. Is the only way to get video from the camera via a firewire port? Is someone giving me bad information as to the firewire port not being on the I-MAC? The camera is not being recognized. Thanks in advance.

Apple has moved on from Firewire and the current iMacs (and most MBPs) have Thunderbolt, USB3 and USB2.
There are Firewire toThunderbolt adaptors. Here's one. You also want a four pin to nine pin FW cable to run from your camera to the adaptor.

Iphone 4 not charging and not being recognized by the computer

I've had my iphone 4 for a little more than a year now and it wont charge or get recognized by the computer. I've seen things about battery and I wanted to see if there was anything else I could try before taking it to an Apple store

Clean the dock connector.
Reset or restart the device.
Try a different USB port on the computer.
Is it even recognized in Windows?
Does it charge when connected to a wall outlet?

Malfunctioning iPod, not being recognized by the computer. Why?

Ok, yesterday I wanted to update my iPod so I plugged it in and I got an error message about my USB malfunctioning and then my ipod was frozen on "do not disconnect". I unfroze it and tried again. Same thing. Then I changed ports and same problem. I kept unfreezing and got rid of the songs I added thinking they might be messing it up. I plugged it in and I thought it was fine. When I checked it the next day when I wanted to use it all my songs were gone. I plugged it back in, restored the iPod settings and it still doesn't recognize it. Its telling me "iTunes cannot read the contents of the iPod '__ iPod'. Go to the summary tab in iPod preferences to restore settings it the factory settings." It won't let me restore, though because of an unknown error. What is the problem and how do I fix it?

Have you had a chance to look at these troubleshooting pages? They may be of some help:
iPod missing in My Computer and in iTunes

Has anyone gotten a solution to the issue of the shuffle not being recognized by the computer?

I have an old shuffle and can't get it to show up on my computer. It also won't sync new music that I've bought without going through ridiculous actions (removing iTunes and re-installing). Anyone have a solution?

If "iTunes pops up and shows me what I have on the shuffle," how can it NOT "show up in devices on iTunes." You have to select the shuffle under DEVICES (in iTunes) to see what is on the shuffle. It seems like the two things you said are mutually exclusive.
Also, earlier you said you can't get the shuffle to show up on the computer, but if iTunes pops up when you plug in the shuffle, it seems to be showing up.
I guess your description is not clear to me...

My memory sticks are not being recognized by the computer...

I just installed 4 1gb sticks of memory in pairs and all of the same maker. I already had 2.5gb of memory installed. Once I turned on my computer and clicked the apple, it is showing that I only have the 2 gb of memory installed! Why is it not showing the other 4 gigs? It is saying those slots are empty and all 8 slots are occupied. I have a total of 6gbs but am only showing 2gb. I restarted my computer twice and keep getting the same result. All memory sticks are seated firmly in the slots as well.
Any suggestions?
I bought the memory sticks from a reliable vendor that sells Mac products.

I don't have the slightest idea of what you are talking about LOL! How do I do cold boot? How do I reset the nvram?
Another thing I noticed that was odd is that I took all memory out of the computer and installed just the 1gb sticks totaling 4gbs. Once I turned on the computer, my desktop screen would not show up on my screen. I got a solid blue screen instead. Once I removed all those sticks and replaced with the sticks previously installed my desktop screen returned! The new memory sticks are brand spanking new. Perhaps I could have had them installed incorrectly as I had them all in the same bank. I Will experiment again tomorrow.

Having a problem with the DVD drive not being recognized by the computer

Compaq Presario CQ60-215DX NOTEBOOK PC, WINDOWS VISTA, Error 10 when trying to reinstall the driver, says cannot start.
I went thru the HP troubleshooting and it said to see the mfg of drive to solve problem! I finally bought a new DVD drive P/N498479-001 for replacement . uninstalled the old drive & then reinstalled the new drive , restarted the computer & it still will not recognize the DVD player! Same error code, same problem. The problem started when I tried to play a CD that appeared to be scratched pretty badly, however my desk top played the CD with out problems? When you click on "computer" the drive does not show up!
I did install a new router a couple of days before this happened, but I am using a data cable to it, so that should not be a problem. Any Ideas?

My ancient iPod is not being recognized by the computer.

If I plug my iPhone in using the same cord, the iPhone is recognized. It was recognizing it earlier when I was trying to upload files.
Now it just has a message about coming to the support page.
I haven't used it in a long time, but was hoping to salvage what I could to let a friend test out if she'd like to get one.
While plugged in it shows the battery icon, a little later will show the apple icon followed by the support link.
My computer is not recognizing it's existence so I cannot complete the last step (refreshing the software).
Have reset and retried. Restart doesn't seem to be the problem. Problem seems to be wtihin iPod, but can no longer connect to reinstall or restore.

That's the odd thing; there is no red X.
I left it plugged in overnight and all of yesterday. This morning it was working, but still not recognized on iTunes (I had disconnected and reconnected before I could check it in iTunes.) The when I tried to connect it again it started acting funny - not connecting, cycling through apple/support/battery screens .
I had suspected the battery was a problem, but I think you may be right - that the hard drive is gone. I have someone locally who may be able to tell me if it's salvagable. I'd like to have it last a few months for my friend, but I know it may be a lost cause at this point.
Thanks for the help. I don't want to give her a fancy paperweight. I wonder if the Apple store would consider looking at this thing or if it's just too old.

My second Generation ipod touch is not being recognized by the computer and is not charging.

Try the following and then try a restore:
- A reset.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Placing the iPod in recovery mode. See:

My iPod is stuck on the Apple logo and won't do anything! It won't turn on, doesn't give me the option to power it off, and to top it all off, it's not being recognized by my computer OR by iTunes when I plug it into my computer.

So yeah...last night I was checking out my iPod (bored at the in-laws) and all of a sudden the screen went blank and the only thing I can get it to do is have the black screen w/ the white apple logo on it. It won't turn on, doesn't give the the option to power down, it won't charge, AND it's NOT being recognized when I plug it into my computer. Not by iTunes OR my computer. I've tried holding down the top button and the home button at the same time...nothing. And since it's not being recognized on my computer, I cannot restart it or go back to factory settings. Someone please help! I've had it for 18 months so the warranty is no longer valid and I don't know how to fix it. THANK YOU in advance!

- I would try placing the iPod in recovery mode and then see if iTunes will see the iPod. try both with the iPod not connected to the computer and with it connect. For recovery mode see:
iPhone and iPod touch: Unable to update or restore
- Next see if placing the the iPod in DFU mode will make it visible

My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?

My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?
Before I updated to OS X Mavericks I was using another external disk that was getting disconnected ocasionally so I bought a new ADATA HD710 portable 1TB Drive and moved the files to it. This new drive which is supposed to be OS X Mavericks compatible takes minutes to show the files especially when opening second and third level folders which has made mu iMac unusable
What should I do?

Your Mac should be able to recognize many different types of drives (including Windows-formatted drives) immediately for Reading, provided they are in good working condition and not damaged. There should be no need to transfer to a different type of drive.
If there is no recognition of this drive, see if it can be seen in Disk Utility.
If your aim is to transfer the data on it DO NOT use ERASE or PARTITION as these will completely erase all the information on the Drive.
If the drive is present while the Mac sleeps, it is likely to drop out and not be seen any longer, especially if it is a USB-powered drive.

HT1510 My iPod shuffle is not being recognized by my computer. I have the original USB cord but when I plug it into my computer there is no recognition. The first time I plugged it in it recognized but never again.

My iPod shuffle is not being recognized by my computer. It is flashing orange and when plugged in with the original USB cable nothing happens to show the computer recognizes it.

Flashing orange usually means it is being recognized by the computer. The flashing means do not disconnected, because the shuffle's "disk" is mounted.
In iTunes (with the shuffle connected), when you look in the sidebar (left side of window), under DEVICES, the iPod is not shown there? Does it say DEVICES in the sidebar?

HT4623 I started updating my iPhone 3gs but now it is locked and sim is not being recognized by the set

Sounds like you had the phone hacked to work on a network other than what the phone was originally locked to. When you updated the software on the phone it reverted back to the lock which makes your sim unusable.
