Problem with USB on MacBook

The problem started when I connected a USB hub with 4 USB ports to my MacBook, at first it was working, but than a message appeared that some USB device is consuming too much power... So than I disconnected the hub, but now only one of the two USB ports on the MacBook work.
And even the one that works doesn't work properly, becouse when I connect my EyeTV dongle the program displays a message that the device is supposed to be connected to a USB 2.0 port and not a 1.1 USB port.
BTW: the hub had an external power supply and I had my USB mouse and my external Time Machine drive connected to it. Oh and now when I tried connecting the external disk to the working port it just made some weird clicking sounds (I tried it on my desktop Windows PC and it spins normally)
So what to do? Is it physical damage or just a system error.

I would try resetting the SMC. Instructions here:

    What type of headphones were you using? I have a set of Microssft headsets, with the built-in mic and connected via USB, and have no problems.

  • Problem with MacMail on MacBook Air - mail with 32MB attachment appearing in "recovered messages" folder every 12 seconds

    Problem with MacMail on MacBook Air
    3 days ago I failed to send a mail with a large (32MB) attachment - and it is no longer in my outbox, draft mails or sent file.
    BUT a copy of this same mail now appears every about 15 seconds in my "recovered messages" folder
    I noticed when I received a system error saying I had a disk almost full issue - there were over 580 copies of the mail with 32MB attachment in the "recovered messages file"
    I deleted them all, and deleted the Trash
    BUT the message still keeps re-appearing every 15 seconds or so.  So I keep deleting them.
    Since then I have not been able to receive mail (altho' I am able to send) and Mail is VERY slow
    I am running MAC OS X 10.6.8
    I am running Mail version 4.6 (1085)

    Also here's the log before it happened. As you can see there is no activity from 9:48 to 10:00 am when the sound occurred.

  • K7N2 deltas mainboards have a problem with usb devices ??

    Ok here is my problem..
    I had installed WinXP Pro with SP1..
    I got a 20 GB USB2.0 disk.i connected it on the both front or rear usb ports.
    When i tried to transfer files to my usb disk or to my PC, in the middle of the copying, i got "Write Delay Failed" error and lost my usb connection..
    I had to plug it out and in again..
    Now, i have an DSL modem..Last night, i was disconnected from internet and my modem's lights gone..I plug it again, no lights..restarted my PC, also completely shutdown Windows XP..Again no lights..
    Then, formatted PC and installed windows 2000 Pr and SP4, until now, my modem worked fine..But USB 2.0 ports are still no use for my usb disk...
    In bios , it's enabled as USB 1.1+2.0..
    I think this K7N2 deltas have a problem with usb 2.0 devices and Win XP Pro..
    Some guys talking about, removing 9th wire earth, but couldn't understand which wire from where ? From mainboard or from usd device's cable ?
    Those cables are fabricated, i think it's impossible ?
    My processor is Athlon 2500+, ram Twinmos 512 DDR 400
    Thanks for reply

    I'm also having this problem. It's happening with my USB flash disk. I was almost buying another one when I tried it with Windows Vista on the same machine and it worked ok, then I tried Arch Linux (with kernel 2.6.30.5) on another machine and got the same error. After that I tried Ubuntu and it worked ok. Seems that Arch's kernel doesn't like my USB flash disk.

  • I am having a problem with my 2009 Macbook Pro

    Hello Everyone,
    I am having a problem with my 2009 Macbook Pro .  A few weeks ago I plugged it into the charger after running it down to reserve battery power. It appeared to be charging, but then all of a sudden my clock and calender reset to year 2000 and then my computer blacked out and went dead. I tried to boot it up but nothing happened (literally nothing).   I have tried 3 different chargers on it, but all I get is a faint green light and even after hours it still won't boot up.   I have tried replacing the battery, but still nothing happens.
    Any Ideas?  I am pretty desperate to get my computer back up and running before school finals.

    You may have to see if an authorized Apple service specialist can check over
    the charging system (magsafe dc-in board, power adapter, and MacBook/Pro)
    and test or run a diagnostic on it, to be sure there is no damage or failed parts.
    When you attached the adapter to charge the computer, after it said it was going
    to reserve power, did you shut down open applications and stop using the MB/Pro?
    That would've been the thing to do, since the margin of run-time near the bottom
    of the power cycle can be wrong by the gauge estimate, it can just quit.
    While I have not researched your year/model/series in detail, I do know some
    models of Apple portable computers have a small battery or capacitor on the
    logic board, separate from the main power battery; it may need replacement.
    A service provider w/ Apple training & parts would be a likely resource to fix it.
    Good luck & happy computing!

  • New problem with display on Macbook Pro retina (Samsung panel)

    Hello All,
    I am a very new people on your forum but a few weeks ago i bought a new macbook pro retina with samsung panel.
    I haven't ghosting effect on my macbook but i have a new and really bad problem.
    I try to found a some information on Russians forums but nobody can help me with it.
    I can see an artifacts in the form of flashing pixels on all display.
    It occurs in 20-30 minutes after the start of work.
    Today i try to test it on game Dirt 2 and i can see defects after 2 minutes after start. So i think it can be reason with Geforce 650 but when i back to desktop and use HD 4000 i still see a problem.
    This is best seen on a black screen with high backlight.
    When i try to connect TV via HDMI i can't see any problem in my TV.
    So i really don't know what could be the reason.
    I attached the video with issue to video hosting
    http://vimple.ru/579f880e8b7045e09f8fc5bc097c5e2b
    Also i have a many software problem like Crashing safari and iTunes. It can be a few times per day.
    I really disappointed with my new Macbook.
    I haven't any problem with old 2009 Macbook pro with Snow Leopard but Mountain Lion is not working well.

    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
    Regards

  • Problems With My New Macbook

    I bought my white Macbook early February and since then i have come aross a couple of problems, so i am posting here to see if anyone else has experienced my first problem and to warn you all of the second;
    - My headphone out only plays out of the left headphone unless I turn the volume right up which causes the right ear to distort profusely.
    - The highly rated "Incase" Neoprene Sleeve I bought with it has left black stains on the sides and looking at other threads it seems that it is only the newer Macbooks that suffer with the problem with the case.
    My macbook is now with the apple repair guys for a few days to sort the headphone problem out and the person I spoke to recommended getting a new case.
    I just think it's ridiculous that they advertise the case with picture of a white macbook when it actually stains them..
    Let me know if you have experiences similar problems with the new macbooks..
    Regards,
    Martin

    I have tried multiple sets of headphones which work fine with my ipod and i still have the same problem and I get the same problem when playing music through itunes, frontrow, myspace and purevolume.
    Whilst i was on the phone to apple support they led me through a few different ways of resolving the problem easily i.e going into system preferences and checking that the pan is centered, restarting the mac by pressing 4 keys at the same time etc. and none of that fixed the problem.
    Hmm it seems that no one else has had a similar problem to this.. maybe i just got a faulty unit.. I should get my macbook back from the repair guys either today or monday so i'll find out then exactly what the problem was.
    Thank you all for your input!

  • Satellite M70-190 - problem with USB

    Hi!
    After uninstall Windows XP and BIOS update, i have a problem with USB ports. My USB flash drive does't work. Windows find it as USB flash drive, but i can't find it in "My computer"
    So have anyone idea about this problem?
    PS External HDD works perfect, as USB mouse, and USB WiMax modem.
    Im hoping someone out there can help with this problem.

    Is described issue the same on all USB ports?
    I mean, I have Satellite M70-159 in front of me and since long time I use 8GB SanDisc and 2GB Toshiba USB stick and both devices are recognized properly.
    I still use original Toshiba WXP installation (updated of course).

  • MSI K8N Diamond - Boot problems with USB devices attached.

    Hi There.
    I have been seeking the forums, but havent found the answer to my problem yet. 
    This is how it goes with ANY USB devices attached to either of the four USB ports on the Motherboard.
    When i turn on my system, it hangs in the POST right after displaying the BIOS version (Which I have updated to 1.6) - I cant use my Keyboard to get to the BIOS setup.
    Without USB devices attached...
    The system boots without problems. And in Windows XP SP2 i can insert my keyboard, mouse etc. and everything works great - both USB 1.1 & 2.0 devices.
    I have disabled the KB/USB.. in BIOS and I have disabled the "Boot on other device" option as well.
    As I have found on this forum, a lot of people have problems with USB Front panel and D-Bracket (USB ports) connectors causing the system to hang - But my D-Bracket (USB connectors) and my front USB port is at this time DISCONNECTED - so this cannot be the problem.
    The D-Bracket shows the "Bios Sign On" information - and stops at that point 
    Am I having a malfunctioning Motherboard here, or are there any solutions to this problem?
    Please help me as I am desperate to have my system work properly.
    Regards
    Stieper

    Well I have read about that somewhere in here, but my problem is NOT with an USB hub, but with any USB device attached to the motherboard's USB slots. It is driving me nuts to be honest!! I think it might be time for RMA 
    What do you say guys - is my Motherboard ready for RMA, or do I have to try something specific berfore sending it to the retailer??
