I have an optical mouse that came with my Mac Pro plugged into the USB port on the keyboard. After a year of working normally, the trackball all of a sudden stopped scrolling down. It scrolls up just fine, but not down. Any thoughts?

I have an optical mouse that came with my Mac Pro, the only thing plugged into the USB port on the keyboard. After a year of working normally, the trackball all of a sudden stopped scrolling down. It scrolls up just fine, but not down. Any thoughts?

Well
I tried all of the suggestions, sort of. I did not have alcohol wipes, but I did take alcohol and pour some ona white paper towel and then rolled the mouse touch ball aroound and that finally cleared up the problem. Just inverting it on paper did not do the reick, it needed some help with the alcohol. Of course the probelm is the debris that gets inside and it really needs to come out.
This is a huge problem for RIM devices users too.

I have a macbook pro4.1 and the sound chip in it failed. My speakers and microphone no longer work. Does anyone know of an external speaker and microphone set that plugs into the USB port so I can continue to use both of these functions?

I have a macbook pro4.1 and the sound chip in it failed. My speakers and microphone no longer work. Does anyone know of an external speaker and microphone set that plugs into the USB port so I can continue to use both of these functions and not have to pay to have the entire main board replaced. Preferably something under $100.

I don't think you're likely to find a set of external speakers that come with a microphone and plug directly into a USB port. There are USB audio cards that look like tiny flash drives but have microphone and headphone ports in them, to which you can connect a typical two-plug Windows PC headset with a microphone, or else you can connect external speakers and a stand-alone microphone. Those adapters typically cost under $10. I don't know anything about the quality of sound that can be expected from them.
I have a Griffin iMic, which is much the same idea but larger, a bit more expensive (retail~$40), and perhaps delivers somewhat better sound quality (I hope so, but I don't know because I've never had occasion to try one of the little ones).

Where do I find my device that I've plugged into my usb port?

I have just purchased a MacBook Pro. I have never had a Mac before so I'm not familiar with correct terminology but....when I plug something into my USB port (camera, iphone, whatever) where do I find it??? I know the connection is made but nothing comes up on the desktop to show how to access the device? I can't find it in the finder, file, or anywhere.

Your System Profiler app in your Utilities folder will tell you what is plugged into your USB ports.

How do I configure my Airport Extreme to see the printer I have plugged into the USB port?

How do I configure my Airport Extreme to see the printer I have plugged into the USB port?

OK. The 6.0 version no longer has a printer configuration that I could find. You might try Printer Sharing in the Sharing preferences.
I would also check the printer's user manual for help with the setup, and that failing check the manufacturer's website and/or tech support.

After ejecting a disk plugged into the USB port using Finder, I am now getting "The disk was not properly ejected" message. This didn't used to happen. How can this be corrected?

After ejecting a disk plugged into the USB port using Finder, I am now getting "The disk was not properly ejected" message. This didn't used to happen. How can this be corrected?

When you right (control) click on the disk and click eject "disk name", do you pull it immeadiatly or wait a few seconds for it to unmount? Try waiting and see if you get the same message. If you do, when the disk is connected go to applications/utilities/disk utility, after opening DU, select the volume in question from the left side bar and try a permissions repair, you may also run verify disk and see if it comes up with any errors (they will be in red)

What can i plug into the USB port??

Would it be possible to plug in a D-Link Bluetooth Adaptor into the Airport Express USB port?
Also can i use a USB hub with the slot, so i can have my printer and BT adaptor plugged in?

Simple answer - no.
See AirPort Extreme, AirPort Express: Uses for the USB port
A Bluetooth adapter of this type must only be plugged into the USB port of a computer.

I have a MacBook Pro laptop purchased in June 2011, and the superdrive no longer works. Rather than have it replaced, I'll buy a 3rd party superdrive that plugs into the USB port. Does it need it's own power source, or will the USB port suffice?

The Apple external SuperDrive actually exceeds the allowed power draw. Because of this, it is only trouble-free on certain models that accommodate this excess.
All others require an external Power source.

Camera not working when plugged into certain USB ports

I just purchased a Creative Live! Cam for use on my dual G5 running 10.5. When I plug the camera into the USB port on the front of the Mac, it works fine with iChat.
However, when I plug it into the back of the monitor (older style Cinema display), it says it is in use by another application.
Any idea how to resolve this? The cable isn't terribly long and the machine is several feet away from the monitor, so I'd like to use the ones on the monitor. (Obviously it gives a power-error message when plugged into the keyboard, which is normal).
Thanks

Seems like it is a USB 2.0 or not problem

My computer and itunes do not see my iphone 'device' when I plug into either USB port on the computer. Have tried all the basic stuff suggested by 'support'. Any ideas?

My computer and itunes app do not see my iphone when I plug it into either USB port on the computer. The cable works because I can hear the iphone start charging off the computer. But there is no indication of the device in itunes or on my hard drive device list. Any ideas?

Have no idea what you mean by "basic stuff". Try EVERYTHING in this support article:

Why wont my computer recognize my iphone 3gs as usb 2.0?

My computer, windows xp with service pack 3, wont accept or see my 3gs iphone as USB 2.0 device. I have gone all the routes spouted by every other site saying their idea will fix it, but it doesn't. Its not because another 1.1 usb device is plugged into the bus, its not the firmware, usb driver needing an update and/or updating the BIOS. I have reverted to the old and standard version of the USB driver. I have restarted the computer after trying every option above. All other 2.0 devices are recognized and work as usb 2.0 except the iphone. I've tried usb legacy support in bios as enabled, auto, and off. My laptop however does see the iphone as usb 2.0. I have even cleaned out the cable connector on the iphone and headphone jack. Every other support site including http://www.usbman.com
and microsoft have offered up the same inoperative solutions above. I even recently reformatted this computer. Please help with something new.

Device not detected in iTunes for Windows

Why does the mouse 'run' to the lower right side of desktop and freeze when a SmartBoard is plugged into the USB port. Running 10.8.5. Sometimes the pointer has a cloud under it but it always freezes.

I run SmartBoards connected to iMacs running 10.7 and 10.8 throughout my school. On one of these computers the mouse has recently started freezing the minute a SmartBoard is plugged in to the USB port. The mouse 'runs' to the bottom right side of the screen, a cloud often is under the pointer, and it is not longer interactive. You can move the mouse upward a bit with the cloud following some of the time but it does not work. Once the SmartBoard is unplugged the mouse works normally. This particular computer worked fine with the SmartBoard until recenlty. Any solutions or ideas?

1. Reset the Pram and SMC
