Slow USB Card Reader - MacBook Air / Windows 7 64-bit / Boot Camp 3.2

Installation of Windows 7 64-bit on my new MacBook Air 11" seemed to go flawlessly from the attached USB SuperDrive. I see no driver issues or unrecognized devices in Device Manager. However, when attaching my Transcend USB 2.0 Compact Flash card reader to load pictures from my camera into Lightroom 3.3, data transfer is mega-SLOW. It takes several minutes (10?) to transfer just 4 pictures. It seems like it may be operating at USB 1.0 speeds.
Installing software from the SuperDrive on the same USB port seems to work fine. Attaching a USB mouse works fine. However, the USB card reader is very, very slow.
If I attach the same card reader, CF card, and cable to another Windows 7 machine, it works fine, so I don't think there's a problem with my reader / card / cable.
Any thoughts about how I might improve performance for the card reader on the MacBook Air (other than running Mac OS)?
Thanks!
Matt

  • Macbook Air July 2013 freezes (Boot camp Win 7 Pro)

    Hi all,
    Just wanted to know if anyone else has had this issue? I am running win 7 pro 64bit sp1 with the latest boot camp drivers (updated via osx boot camp utiliy a few days ago) and all windows updated up to date. Everything works fine and has installed, but at least once every day the whole computer just freezes up and becomes non responsive. All I can do is power it off and do a hard reset. This is on a brand new July 2013 Macbook Air 13" with a 512gb PCIe Samsung SSD.
    I have taken it into Apple to take a look at, but they refuse to acknowledge the problem saying it is a software issue with Windows. They did their diag tests in-store and everything came up ok. But the funny thing is, the laptop still freezes every day! And all the errors point to a hardware issue.
    Anyway, I did a bit of googling and from the sounds of it it is most likely a faulty motherboard/controller chip. I just wanted to hear from others out there if they were able to fix it any other way other than getting a replacement laptop? Are there any diag tools that I can run to see if the SSD controller is faulty?
    Here are the errors I keep getting
    Event ID 11
    The driver detected a controller error on \Device\Harddisk2\DR3
    The driver detected a controller error on \Device\Harddisk2\DR6
    The driver detected a controller error on \Device\Harddisk2\DR5
    Some other errors which I think could be related
    taskhost (2744) WebCacheLocal: A request to write to the file "xx\AppData\Local\Microsoft\Windows\WebCache\V01.log" at offset 184320 (0x000000000002d000) for 151552 (0x00025000) bytes succeeded, but took an abnormally long time (2451 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.
    The driver \Driver\WUDFRd failed to load for the device ACPI\ACPI0008\4&1df6a035&0.

    I don't think that PCIe which is only Samsung device would use any other NAND.
    I do think Apple is responsible to provide drivers and enable AHCI mode for it to function properly.
    Was concerned that too many people give far too little space to Windows partition. And that they don't set aside the 11% that Samsung Magician would recommend setting if it could.
    I first read about the MBA and its new SSDs here:
    2013 MacBook Air Disassembled and Benched - Samsung 256GB PCIe SSD ...
    And Samsung PR:
    http://www.samsung.com/global/business/semiconductor/news-events/press-releases/ detail?newsId=12921
    > Samsung started providing the new SSD to major notebook PC makers earlier this quarter. The XP941 lineup consists of 512, 256 and 128GB SSDs.
    So no matter what size it is still going to be Samsung NAND all the way through.
    PCI Express-based SSDs for Ultrabooks, then. The new XP941 series uses PCIe's wider data path to read at nearly 1.4GB/s
    http://www.engadget.com/2013/06/17/samsung-makes-first-pcie-based-ssd-for-ultrab ooks/
    So maybe searches on "XP941" can help turn up tips from around the net.

  • USB Card reader works on MacBook Pro but not Mac Pro

    I have a random "All-in-1" card reader from Quantaray. I'm trying to mount my CF card because it takes forever and a day to import HD video directly from my Canon 5D Mk II.
    It works on my MacBook Pro (Mid 2010). Both computers are running 10.6.8. All I have to do is plug it in and it appears on the desktop on my Macbook. But not on my Mac Pro.
    I've already tried resetting the PRAM and SMC. No dice
    It shows up in the System Profiler under the USB High Speed port as a usb card reader but I can't find it anywhere; not even in Disk Utility.
    Any ideas?
    Thanks

    jaypie77,
    First, you must identify the application that created the file. If it truly was Macromedia Flash, fine. Once you know which app created the file, make certain that the same application exists on the Mac Pro. If it does, set the file to open in that application: Open a Getinfo window for the file, then use the "Open With..." dialogue to choose Macromedia Flash (or the correct application) to open the file.

  • MacBook Pro now does not recognize USB card reader

    My computer recently stopped recognizing my usb card reader. The usb port works fine with my iphone and ipod. The card reader works when plugged into a windows based machine. The problem is not related to OS 10.6 because I had the issue prior to upgrade. I must of updated something software related that is causing the problem. Anyone have any ideas?

    My computer recently stopped recognizing my usb card reader.
    We'll need to know exactly what you mean by this. Plug in the reader, without a card in it. Go to Apple Menu > About this Mac > More Info and click on USB in the left column of System Profiler. Do you see *Mass Storage Device* listed under one of the USB port entries in the right part of the window? If so, the reader is recognized. If not, it really isn't. In that case, reset the SMC in your MBP:

    Then test again and post back with results.

  • Whenever I plugged in HP laserjet M1132 printer usb to my Macbook air,a screen pop-out "the disk inserted are not readable by this computer".I uninstalled

    Hi,I'm new here and I think my problem were discussed few times before.However,I tried to follow the solutions similiar to my condition but it does not work.My problem is whenever I plugged in the HP printer (Laserjet M1132 MFP) usb to my Macbook Air,a screen will pop-out and read as 'the disk inserted is not readable by this computer'.I even bought my Mac to the Mac store but the situation remains the same.Okay with other printer but not with my HP.Sigh.The HP printer worked just fine with other computers (not Mac).I'm really sick of it.Please help me.I once plugged in an external hard drive & started Time Machine with it.The printer problem started after that.However, the hard drive plug-in works just fine.
    Your attention of above matter is highly appreciated.Thank you.

    Here is what worked for me:
    I reset the System Management Controller on my MBA.  To do so requires shutting it down, keeping it plugged in to power (I also unplugged both USB connections), and then from a powered off state I simultaneously pressed Shift + Ctl + Option + Power (I did this once and it did not work so I tried again and did it 3 times just to be safe), then released them at once, then I pressed the power button.  Problem solved.

    I also tried uninstalling the using the repair Disk Permissions with Disk Utility and moved the HP Printer software accessories to the trash (you can search the web for how to do that but that did not solve the problem either).  Neither of these options worked.

  • Sun Ray - How to get external USB Card Reader working

    Dear All,
    i have the following problem. Maybe someone could help me or give me a clue to solve it.
    SunRay Software 5 installed
    Window 2003 R2 TerminalServer
    Here my question:
    I use a kiosk session with a smart card to conncet to the windows server - works perfect.
    Login Screen and go.
    Now i have to have to authenticate myself with an external usb card reader and smart
    card (connected to the sun ray) to use a certain application on my win2003 server.
    Via the windows rdp session (from the laptops) everthing is ok. The information from
    the card reader is transferred to the server.
    If i use the Sun Ray nothing happens. So here is my problem:
    How do get the authentication information from the smart card to the server?
    Thanks in advance
    Best regards
    Hans-Peter

    Basically, reinstall the Boot Camp video drivers manually and if that doesn't work then go to the AMD/Radeon website and install the Windows drivers directly for your video card model.
    If you want to do a search you will find others that have pretty good luck doing it either way.

  • Camera / USB card reader not connection to macs anymore - fine with PCs

    Hi there,
    I have a Canon EOS 50 which has a CF card - I normally connect this to our macbook pros with a crd reader via usb. Alternatively, I connect the camera directly.
    Yesterday, something started to go wrong.
    I was connecting the card to download photos - at first it recognised the card as an external drive, but was taking ages to read the photos. Then it flashed an error message up that it couldn't read the format of the disk (it had previously for about a year!).
    Now when I connect the card via either reader or by connection to the camera, it doesn't recognise the card at all.
    I tried this on both my mac book pros we own. Same issues.
    Canon HD camcorder connects absolutely fine via usb, as does Ipod - so it isn't the usb port.
    I think the cards are ok- (same issue with two different CF cards)
    The camera connected no problem to my brother-in-law's vista machine, and downloaded the image files.
    I tried connection with two different usb cables as well.
    Any ideas as to what has happened?
    Thanks,
    ThreeIsles

    Last year I purchased a USB card reader to have available with my laptop when I travel. It experienced the same problems you are having. It also wouldn't work with my G4.
    I looked on the manufacturer's web site and sent their Customer Support an email explaining the problem. They sent me a new reader at no cost. It works. Suggest you do the same.

  • When I plug in an USB stick, my MacBook Air disables all USB devices

    When I plug in an USB device, my MacBook Air disables all USB devices and the keyboard. It looks like it would freeze, but all applications still work. It just does not respond to neither keyboard nor mouse. The only solution is to force-restart it. What can I do? I am using Lion and have updated it. The same error occured with Snow Leopard as well. Unfortunately, it sometimes happens and sometimes not. I have a suspicion it is related to the devices power consumption in corelation with the battery charging status.
    I am using a MacBook Air 13", late 2010 version.

    Have you tried plugging the flash drive into a different Mac to see if it works? The Air shouldn't have any problem with it, I use a couple of flash drives in mine, although I don't have a pq1. Did you try both USB ports on the Air? Do you have another flash drive you can test in the Air, or a different USB device, like a hard drive or printer?
    The only thing I can think of is either a bad flash drive, or a bad USB port on the Air. Sorry, can't be more help than that.

    eventually i made a coorect usb windows 7 and put it back to continue as it was saying so,but there is no change and the screen still is dark and says no bootable disk ,insert.
    how to solve the problem?

    Right now I have 6 different systems installed. Windows XP, 7, and 8 plus Linux Mint, Commodore, and OS X Snow Leopard (for old times sake), all running on Mountain Lion.
    I recommend reading the user manual as it greatly helps getting through the steps, however an intuitive person should pick it up fairly easily.
    Thanks to BobTheFisherman for the link.
    There are other ways to get Windows on a Mac but I'm a big fan of open-source software.
    Give it a try. You might like it or it may not be your cup of tea.

  • Installed Snow Leopard 10.6.3, now usb card reader (CF, SD etc.) is not rec

    For some reason my MacBook doesn't recognize my usb card reader at all now. I have never had this happen before. It doesn't matter if my camera's cf card is in the reader or out or if it's plugged into my usb hub or directly into the MacBook. I just installed Snow Leopard so I think that's causing it, however, I don't know what to do to fix it....

    Shutdown and restart, Zapping the Pram. Then, try the card again.

  • New Lexar USB card reader, X tells me low power

    The card reader worked fine yesterday.
    Today, no matter where I plug it in (usb port) or the keyboard, OS X pops up a window telling me there is low power for this device. Therefore, I can not mount the CF card in the Lexar card reader.
    This card didn't have any installers. Should I look for some on their webpage?
    I guess I should have bought the Sandisk card reader, about the same price, eh?
    Should I start looking for my receipt to trade it for the Sandisk card reader?

    Lexar USB card reader is: Model RW022 Rev A
    I did contact Lexar using their 24 hour live chat on their webpage. An excerpt from the conversation is pasted below. I wrote "Lexar" and "me" to hide identities of those involved.
    Lexar: we are sorry to say that, our card reader is compatible with USB 1.0, USB 2.0.
    Lexar: not compatible with 1.0
    me: so the card reader is not compatible with 1.0 on a Mac
    Lexar: exactly.
    Lexar: not compatible with USB 1.0
    me: ok, thanx
    Lexar: is there any thing else i need to assist you.
    me: yes, what versions of Mac OS is this card reader compatibvle with?
    Lexar: this reader RW022 is compatible with MAC tiger.
    me: from your webpage this card reader is compatible with USB 1.1 and USB 2.0
    me: http://www.lexar.com/readers/compactflash-2.html
    me: All Macs, even older ones, were USB 1.1
    Lexar: all lexar products are compatible with USB 1.1 and USB 2.0 only.
    me: My mac is USB 1.1
    Lexar: then it will work.
    The conversation went on and Lexar asked for time to research this, which I told them to take all the time they needed.
    In the end though, Lexar asked me if I had it connected to the keyboard, and I answered yes, and they said it should be connected to the tower.
    So I'm assuming connecting the card reader to the Apple keyboard doesn't have enough power (as the keyboard and Pro Mouse are also using the power there). They told me it should work if connected to the tower. I thanked them and said I'd try that.
    So I'm assuming that this card reader should either be connected to the Cube directly (without turning it over I hope I have 3 USB ports under there) or to a better USB port that is powered (than what I have) so that the card reader gets plenty of power. In the past, I simply connected my very old CF reader [in OS 9.x] to the keyboard (like I do my scanner) and it worked.
    Do most card readers need to be connected to the "tower" or to a powered usb port?

  • Not recognising USB card reader and also PhotoBooth issue

    Hi,
    I'm a new member and a bit of a numpty when it comes to Mac (new owner).
    My Macbook Pro is giving me some grief tonight and I have 2 separate (i think) issues.
    It will not recognise my USB card reader. It worked fine last week and I did eject it properly before removing it. I've tried the card reader on a PC and it is working fine....
    Also when I go to open Photo Booth it tells me that my camera is not connected or in use by another program. But as you know the camera is built in!?!?!
    I'd be very grateful for any thoughts on how I might fix the problems. The nearest Mac store is 2 hours away....
    Many thanks in advance

  • I connected a USB card reader and can't see it.

    I connected a USB card reader and cant find it to download the pictures on the card.

    To tell you the truth, I don't know.  I am pretty knew to Apple products.  I did get the card reader to work.  All I did was leave the card reader connected and pulled the card out.  I waited a little bit and then reinserted and a pop up window came up with all my pictures.  I don't know why it didn't work the first few times I tried it.  Thanks for the reply babowa.

  • Motherboard hangs on POST when USB card reader is plugged in

    Hi there, I am using the MSI Z77A-GD65 GAMING motherboard. I am using the following USB card reader which I bought from a local store: Amazon.com: Epraizer Universal Flash & SIM Card Reader/Writer, USB 2.0: Computers & Accessories
    However, whenever I boot with this device, my BIOS is stuck at error code 'C6'. A check on AMI's website shows that this related is probably related to boot devices. I am able to boot fine with other USB devices plugged in, such as USB thumbdrive and USB hard disk.
    At first, I thought it was a problem with my device but I can boot fine with the memory card reader plugged in on all my other computers. This makes me wonder if there is a firmware fault? I have tried disabling legacy USB and removing USB devices from boot order, but nothing helps. I have seen that in the forums some BIOS updates for some motherboards fix this issue, for example: **Official MSI Z77 Mpower Discussion Thread** - Overclockers UK Forums , where in one of the BIOS update the changes reads: Fix the issue that the system will hang 0xB4 or 0x99 when use customer usb cable or usb cardreaders.(USB cardreader: KAMA reader Tr, Akasa card reader).
    So I was wondering if it's a common issue with MSI motherboards? Will there be a fix or my motherboard is now too old to be supported? I purchased this motherboard two months ago btw
    P.S it works fine when I plug it in in Windows. I have tried both the ports in front and at the back, USB 2 or 3.

    It is then obviously a compatibility issue with that particular card reader and that particular board model. As your board is long time EOL ("End-of-life") and has been replaced by two generations already there will be no further updates. What bios versions did you try already?
