Macbook Pro right USB port disconnects

Hi - When using the dialup modem adapter in the right USB port it will disconnect after 3-4 minutes but works fine in the left port. Flash drives & scanner seem to work OK in the right.
Also, a friend has computerized embroidery sewing machine and the right port does not recognized it but the left does on her MAC.
Are Macs were bought a couple weeks apart.
Is there a setting for each USB port that maybe wrong or is this just a defect?

Well, does that link...

still lock up your Mac? No way it should have any such effect.

Macbook Pro 15" USB PORT DOESN'T RECOGNIZE ANY DEVICE.

I got my macbook pro 15" for about 1 year and 2 weeks ago, when I turned on my macbook and put my mouse ( Death Adder) into the USB PORT, my macbook DOESN'T RECOGNIZE IT. There are 2 usb ports on my macbook, I tried both port and there was only one port work correctly, the other one didn't work at all, I also tried to put my memory stick, external hard drive, vodafone 3g usb, ipod,....into that USB PORT but non of them worked. Is there any one here have the same problem???? Can you guy help me please. I stay quite far away from Apple Store so it is hard to bring it to repair. I tried to reset SMC, Update Software,...but still not work...HELP ME PLEASE...

I can't fault your troubleshooting. Sounds like a bad port.
Home remedies are limited. You can grab a magnifier and shine a flashlight in there. If you see any foreign material, use a toothpick or other non-conductive tool to extract it. If you can, give it a good blast of (dry, canned) compressed air to blow any particles loose.
Sometimes you can trick a flaky USB port into working at least intermittently by plugging in an extension cable or right-angle connector. Play with a device that lights up so it's easy to see whether it's working.
Take a hard look inside the connectors at the end of your Death Adder and other frequently-used devices. If you see any corrosion or bent pins, that's what damaged your USB port.
If the port requires physical repair, it's best to use Apple or an authorized dealer because if they make things worse while trying to fix it, they have to make it right. Joe's Appliance isn't similarly accountable.
If you need more USB ports, ExpressCard to USB adapters are dirt cheap.
Good luck.

Late 2011 MacBook Pro; one USB port not recognising anything

Hi,
I've had my MacBook Pro since January 2012, so I believe it is the late 2011 13" model. I'm currently running OSX 10.9 although the problem I've been having has been going on around 3 or 4 months, I think I had OSX 10.7 installed when the problem started.
One of the USB ports on my Mac (the one on the left when looking at them face on) is not recognising my external hard drives, or recognising/charging my iPhone when plugged into the USB. The other USB slot works fine and recognises external hard drives, however when I insert the hard drive into the faulty USB input, although the hard drive lights up and starts whirring as if it is ready to start functioning, it does not appear under the 'Devices' tab of the Finder screen, but does appear and function when using the other port.
Similarly, when I plug my iPhone 5 into the faulty port it is not recognised/does not start charging, however if I leave it running and come back later I often have at least a level of increased battery life which suggests that it does intermittently charge from time to time, and again it functions normally when using the fully functional port.
I've tried the NVRAM reset as I have read in another post but to no avail. Is this likely to be a mechanical fault over a software problem, and if so what could be wrong with it?
Thanks for the help in advance.

thank you shootist, at least now I know the problem is as serious as I dreaded, but will not loose hope waiting for a miracle and the port works again

Macbook Pro First USB port ejecting things

ok so my brand new(mum bought it late Nov. didn't start using it until christmas) macbook pro's first usb port (closest to person using it) will eject anything that is put into it when you try to put something into it what can i do to fix this? should i take it to apple? since its new and i can call them and such during this month?

Does this happen with USB flash drives too, or only with hard drives? Have you had it happen with more than one hard drive, or just one?

Brand new Macbook pro one USB port stopped working

Brand new Macbook Pro 15 with Retina display. One of the USB ports stopped working after 24hours.

Serial Port Configuration and Port definition is reset by

If no good I would return the machine ASAP:

My MacBook Pro's USB ports will not work. Is there anything I can do to fix this?

I bought it in late May of '12. The USB ports stopped working a couple of months after I bought the computer. I did not spill anything on it or drop it. I went in and had them fix it and they worked for about a month. They will work occasionally and it takes me removing and entering the USB connector multiple times before it recognizes that anything is there. The computer is no longer under warranty and I don't want to have to pay a bunch of money to have it fixed. Is there anything that I can do to fix this or am I going to have to have someone else do it.

Maybe a PRAM reset will work:
http://support.apple.com/kb/ht1379
If there is no change, bring the MBP to an Apple store genius bar for a free evaluation. Bring the recalcitrant devices with you. This should at least determine exactly where the fault lies, with the MBP or the externals. Any repair costs quoted you may accept or reject.
Ciao.

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.
Steps I've taken:
Disk Persmission
PRAM
SMC

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

Right USB Port not reading External HD

I'm using Mid 2014, Retina, 13-inch, Macbook Pro. I noticed that my right USB Port is not reading my 1 TB WD External HD but able to use mouse. How to fix it?

According to the fount of knowledge that is Wikipedia…
https://en.wikipedia.org/wiki/USB
As with previous USB versions, USB 3.0 ports come in low-power and high-power variants, providing 150 mA and 900 mA respectively, while simultaneously transmitting data at SuperSpeed rates.[25] Additionally, there is a Battery Charging Specification (Version 1.2 – December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.
It doesn't make sense to me that a 'low power' USB port would output 500ma unless it was working in USB2 mode.
A unit load is defined as 100 mA in USB 1.x and 2.0, and 150 mA in USB 3.0. A device may draw a maximum of five unit loads (500 mA) from a port in USB 1.x and 2.0, or six unit loads (900 mA) in USB 3.0.
You may want to get the genius to confirm the spec for both ports if you go along to a store, I guess they may have limitations.
I would also boot into recovery mode just to see if the disk pops up in Disk Utility via both ports - that could indicate the port is being rendered useless by the OS.
Apologies, you appear to have tried that already.

MIDI controller is working in the right usb port, but it doesn't in left

Hello all,
I have this strange problem, yesterday i bought MIDI keyboards it's M-AUDIO Keystation Mini 32
The problem is that when i connect it to right USB port it works flawlessly, but when i connect it to my left USB port - my macbook pro recognizes the device but it doesn't send any midi data - to put it in other way: it is not working.
I have checked, everything is working fine In the LEFT usb port( wireless mouse, external HDD, Flash drives, Iphone) except my MIDI Keyboard.
Can anyone help? i've been searching for days for the solution, but, i'm out of ideas.

Hey,
i have the exact same problem! I was in the apple store and they replaced my macbook. then it just worked fine for a few days and now the problems is there again.
Do you already have a solution?

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

Transfer of mini-DV tapes from Panasonic NV-GS120 to MacBook Pro via FireWire port (9-pin)

I am new to Mac and love it. I would like to transfer my old mini-DV tapes from Panasonic NV-GS120 to my MacBook Pro via FireWire port (9-pin), but am not sure which port to use on the video camera. Reading from the top on the Panasonic video camera there are three options: a "mini-usb" port, a "remote/mic (plug in power)" [not likely] and finally a "A/V out phones" jack entry [which I use for viewing the tapes on the TV screen via the jack cable ending up in a red, yellow and white cable to plug into TV.
I have read Bengt Wärleby's excellent instructions and am ready to buy the FireWire cable (9-pin in one end - Mac), but I am not sure if it is the mini-usb or jack-stick exit of the video camera. Or, indeed, if there is talk about an external A/V box needed to decode and transfer the digital tapes to iMovie on the Mac.
Any clarification is highly appreciated. Thanks for all suggestions.
JLens

The port you're looking for is the DV Port (in your manual it's marked as control component #55). I looked up your camera and it does have it. That's the port where the firewire should fit. Hope to have helped you.

In my macbook pro hdmi, usb & SD card reader not working

In my macbook pro hdmi, usb & sc card reader not working.
i have tried the SRM reset done, till not working started.
Could you please resolve this problem,

Welcome to Apple Support Communities
Simply take it to an Apple Store or reseller if it's in warranty. Your Mac will be repaired or replaced for free because it looks a hardware problem rather than a software issue.
If it's not in warranty, hold Command and R keys while your MacBook is starting up, and reinstall OS X. If it doesn't work, you can't do much more to solve the problem

Can I use a 2009 iMac as external display for 2007 macbook pro with DVI port only

I have a late 2009 imac with minidisplay port and a 2007 macbook pro with DVI port. I connected a mini diaplay port to DVI cable but all I get on the imac is a blank screen when I press F2. Can I use the imac this way?

I'm not sure if it works with DVI but your late 2009 must be a 27". Try Command-F2 or Copmmand-Fn-F2

Right USB Port faster than left (MBP 15 2013) ?

Hello guys,
I just installed Drive Genius 3. Im assuming bad sectors on my external hard drive. When I connect the drive on the left usb next to thunderbolt normal scanning says can take up to 8/9 hours.
Plugging it into the right USB port only says around 3,5 hrs.
Is there a difference in speed?
One more question:
Dont all new drives have SMART? My latest WD Elements says it has no SMART Status. So I cant find out any bad sectors except by doing a scan with Drive Genius?

The thing is, when I use an adaptor with the keyboard, it works fine in Logic. But the USB port cant seem to power the keybaord like the left one can. Could the USB port on the left really be broken if it is working with Logic with the adaptor?
