  • My Macbook Pro Retina's USB port on the right side not working at all

    Dear all,
    I received my macbook pro 15inch with retina display a week ago, but not until today had I got the chance to use the USB port on the right side, only to find out that it is not connecting to anything at all. I have tried to use my iPhone 4 and iPad 3 with two different cables, my USB thumb drive, and my Blackberry 9900, none of them are charging nor shown in iTunes/Finder. All of above works on the left and on other windows machines too.
    I'm also not able to charge my Blackberry with the usb port on the left side, thought it would pop up a message saying "charging not supported" on the phone.
    For you information, I have applied both updates including the one released few days ago. I have also tried to reset the PRAM. Also, I have migrated from my old late 2008 13inch unibody Macbook using Migration Assistant, not sure if this would affect anything.
    I'm aware that there have been reports and discussions regarding the USB port not been able to run devices on 3.0 speed, but I wonder if anyone else have the same problem with me, where the port simply not connecting to anything at all?

    I also have a problem with the USB port on the right side of my Retina MBP.  The USB3.0 port on the left side works fine, even with high speed external SSD enclosures, like the OWC Mercury Extreme Pro 6G which enables me to copy large files at a sustained rate of 160-170MB/sec.  Wow USB3.0 and the Mercury SSD is a FAAAAST combination connected to the Retina MBP.
    However, like the forum entries about the USB3.0 ports in general on the new Retina MBP, the USB3.0 port on the RIGHT side is plagued with dropping intermittently, disconnecting my external hard drives while copying large files AS WELL AS disconnecting while just sitting there connected to an external hard drive and doing nothing.
    Therefore, since I don't feel like returning my Retina MBP and waiting weeks for a replacement, I have chosen to only use the left side USB3.0 port for now.
    I have my suspicions about why the right side USB port might be more problematic than the left side one.  I found this older post on the internet about how "Not all USB ports are created equal on MacBooks..." that talks about how on older models of MacBooks one of the USB ports shares a USB hub with multiple other devices like the iSight camera etc. therefore making it less tolerant of heavy traffic or something like that.  (http://www.wired.com/gadgetlab/2008/05/the-macbook-all/)
    Therefore, I wonder if the right side USB port is sharing a USB internal hub where-as the left side one is more 'dedicated' and therefore in my case able to handle the high speed transfers/traffic I am throwing at it with my external SSDs.
    I have also read that USB3.0 in general, on non-Macs, has had trouble for years.  For instance, some forum entries on Apple Support Communities and other non-Apple forums has made mention that 'they' are not surprised at the problems encountered on USB3.0 external hard drives connected to the Retina MBP because Windows laptops have had a lot of flakey problems with USB3.0 for 'years'. 
    Also, I have recently purchased a "Buffalo" external Thunderbolt 1TB drive from OWC and have been doing Clones onto that drive for several weeks.  I use SuperDuper to clone >600GB of data on my 768GB Retina MBP several times a week.  And, I have (knock on wood) not had any problems with the stability of my externally connected Thunderbolt drive.
    So, in my case, I am racking it up to high-speed stresses on the USB3.0 ports at least in part...and perhaps the possibility that the LEFT side USB port on the Retina MBP is more dependable and/or a more dedicated USB port than the right side one.
    This doesn't really solve your problem, but it may at least help you feel like you are not alone.

    tstevenson08,
    It sounds like a hardware issue honestly, as discussed in a previous thread regarding this issue.

  • Usb 2.0 port on the right side (beside thunderbolt port) of macbook air 13" 2011 is busted, one of the pins inside the usb port is bent, is this replaceable? saw the pix on ifixit that it is part of the logic board.

    usb 2.0 port on the right side (beside thunderbolt port) of macbook air 13" 2011 is busted, one of the pins inside the usb port is bent, is this replaceable? saw the pix on ifixit that it is part of the logic board.

    The fix is a new logic board. It might be tempting to turn off the computer and start poking around inside to fix it yourself but you risk separating the port from the logic board and doing even more damage.

  • Lenovo W530 USB Port

    I am posting this in the hope that some Lenovo employee will see it and finally rectify the absolutely atrocious customer supprt that they have extended to date.
    I bought a Lenovo W530 a while backj, and ordered a USG port at the same time. The USB port came immediately, but the W530 was subjected to a series of 2 week delays (or stalling by Lenovo to be honest), and when it finally came, the power jack that came with the W530 didn't fit the USB port (it has a couple of lugs presumably foir a tighter fit, but the USB port was different). I raised iyt with the Dublin support centre, but again all I got was prevarication and stalling, until eventually they stopped replying. 
    So I have a Lenovo W530 (which has not been the best machine I have ever bought and will be the last from them) and a USB port that cost me £90 but which I have never been able to use.
    Any ideas on how best I can get this rectified?

  • 2010 i5 MBP USB Ports Not The Same?  Griffin iMic Issue

    I have a 2010 15" i5 MBP. I got one of the white iMics and it works fine on the port thats closest to the screen. However, when I plug it in to the port that's closer to the SD slot, it doesn't work. Under the audio settings screen, I see the iMic under Input, and the slider is to the right, but the VU meter doesn't register anything. However, when it's in the USB port by the power adapter, it works as it should.
    I have read that certain model MBPs have USB ports that are not the same, and some people have problems with programs like Serato when it's plugged into the front port. Traktor and Serato have even mentioned that on the MBP there is one "good" port and one "bad" port.
    Curious if anyone else noticed this. Again, it seems to only affect 2010 i5 MBPs.

    Hi WebBrowser2,
    As I understand your query its not a single doubt you are having at all, actually it’s a bunch of multiple doubt you are carrying here in your mind allied to Mac Book Pro (USB Ports are not working).  There might be various reasons behind- not working of USB ports in Mac Book Pro, as you already had searched out various ways to fix all your issues. A few months ago, I faced the same issue as my USB port was suddenly stopped to respond, then I also tried to find various ways to get rid of this issue, and I found an informative blog link which has fixed this issue and make me tension free.
    For more information visit at- http://www.olmtopsts.com/blogs/when-macbook-pro-usb-ports-not-working.html
    And I am hoping- it will assist you in the same way as it assists me.

    Thanks,

  • Why does my nook open iphoto when i plug it in the usb port on the back of my imac running 10.6.8

    I have downloaded Adobe Digital Editions and downloaded Overdrive from the public library. When I plug the Nook eReader in the USB port in the back of the iMac, iPhoto opens immediately. I know this is not a forum for Nook eReaders, but I have to start somewhere and figured since iPhoto is opening automatically, maybe someone can give me a clue.
    thank you,

    Most likely, because your Mac and iPhoto think that you have connected a camera or mass storage device that has images on it.
    Not sure where to go from there, but I would start by looking at the setting in both iPhoto Preferences and Image Capture if I wanted iPhoto to ignore that device.

  • How do I use my ipod in the car without it constantly charging?  I have to use a docking cable into the USB port because the 3.5 mm to 3.5mm jack I bought doesn't work on the ipod.

    How do I use my ipod in the car without it constantly charging?  I have to use a docking cable into the USB port because the 3.5mm to 3.5mm jack I bought doesn't work with the ipod (although it does work with an MP3 player).  My ipod is a 5th generation 80GB classic.

    I know this is old - but did you ever get this working. Thinking of getting a 780 ti card and I have an older mac with the mini-displayport too.

  • How can I connect my iPad to a TV that only has an s-video input available but also has a usb port on the satellite box available.

    I would like to connect my iPad to my older TV but the only inputs available are the s-video input port on the TV itself and there is also a USB input port on the satellite box that feeds the TV. I could also split all the RCA jacks to accomodate another input here. Thanks in advance for any and all help with this problem of mine..............RR.

    There is no s-video cable available for any iPad.
    The USB port on the cable box is for maintenance use only.
    There are RCA cables available:

  • 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.

    - Try restoring the iPod, first from backup and then try to factory settings/new iPod to rule out a software problem.
    - Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and broken or cracked plastic.
    - Could you have damaged something when you took the iPod apart and replaced the Home button?

  • I have three ipods, none of which is being recognized by my itunes. I have the current editions and tried different USB ports. The mouse works just fine in the USB port. I have reset the ipods. Any ideas if it's the USB or the ipod or what's going on?

    I have three ipods, none of which are being recognized by my itunes. I have reset each ipod, with no results. I wonder if the problem isn't with the USB ports. The mouse works fine in each port; nothing happens when I plug in the ipods. I have tried two different USB cables. I have no other USB devices with which to test. I have made sure I have the most recent updates and rebooted the computer.  Any idea what is going on?

  • Can't use my HP Deskjet F4580 Wireless Printer with the AirPort Extreme Base. The printer is NOT connected at the USB port of the AirPort Extreme, and is placed in another room. It worked just fine with my previous router (Linksys WRT54G). Help me!

    Hey Guys!
    I just got my AirPort Extreme Base, but I can't use my HP Deskjet F4580 wireless printer with it.
    The printer is not connected to the AirPort Extreme's USB port. It is placed in another room, and I'd like to use it (the printer) wirelessly (not connected to the USB port os the AirPort Extreme), as I used to. There is no place for the printer close the AirPort Extreme. It worked just fine with my previous wireless router (Linksys WRT54G). I'm very disappointed with the AirPort Extreme Base Station because of that!...
    Can you help me? Please?!
    Thanks Folks!

    This must be a tough one, no suggestions at all.
