USB Stick not Working in MBP

I have a 17" MacBook Pro running the latest OS X, and I have a Lacie USB key. When I plug in the USB key, my MBP does not recognize it at all. Nothing. However, when I plug the same USB key into my iMac (running the save version of OS X) it works just fine. The USB key also works perfectly on my Windows 7 PC at work. Other USB devices (hard drives, etc.) DO work on my MacBook Pro, so it's not as if the USB slot is busted. I've tried both slots to no avail.
Does anyone have any idea why this would be happening, or what I can do to try and fix it? Thanks!

Have you tried other USB devices to confirm it's the 17" MBP?
If you can confirm it you should then backup your data and reinstall OS X by c booting off the installer disk.
You can also shutdown the computer, hold the D key and reboot, hold the D key for quite some time and you might enter the hardware tester.
If you reinstalled OS X and your problems continue, you should make a warranty/service call with Apple.
Good luck

Usb stick not working (solved)

I copied some files to my usb stick and made sure it was working. Then I copied a open office file from my wifes computer running vista. After placing the usb stick back into my computer I got the following message

I went to xsessions and got the following message.

Seeing as the stick worked before I copied a file from vista, did the vista change something in the usb so it will not work in anything but windows? Is there anything I can do?
changed /dev/sdc1 /mnt/usb vfat noauto,users 0 0
to /dev/sdc1 /mnt/usb auto noauto,users 0 0
and now everything works fine

Why does a USB stick not work with my ipad mini

I bought an IPad mini and got an adapter to hookup a USB stick, but no matter what stick Zi put in the connection I get the same error message. " cannot use device the device requires too much power".

YOu can only download from cameras, SD cards and certain flash drives (i've had a 50/50 success rate when I've played around, with no consistent size or brand that always worked). The only formate it'll see are photos and videos and even those must follow a very strict naming convention.
There is zero support to transfer documents, music or any other kind of files to the iPad. As well as zero support for exporting anything off the iPad.
If you want to share your pictures, try uploading them to something like flicker or other online services.

USB Keyboard not working on MBP

Hi,
I have a mechanical usb keyboard (PC) that I like to use, but it isn't working on my 2010 MBP. I did a bit of googling & a series of experiments to figure out the problem, but I am no closer to a satisfactory solution. Here are my observations:
1. If I connect the keyboard to a USB port on my MBP, the caps, num & scroll lock keys illimunate for a second & go out, but the keyboard does not respond subsequently. I can see the "Change Keyboard Type" button in System Preferences, but the wizard fails to detect my key presses. System Information shows a "Generic USB Keyboard" in the USB Device Tree (current available - 500mA, current required - 100mA)
2. I have Windows 7 installed on my MBP as well. The keyboard works perfectly there.
3. If I keep the keyboard plugged in & reboot, the keyboard works in the rEFIt menu normally. If I boot into Mac OS, the keyboard continues to work at the login prompt as well. However, post login, the behaviour is kinda erratic, and sometimes it works for hours together, and sometimes stops working after a few minutes.
4. Whenever I plug the keyboard in or out of a USB port, I see the following line appear in my system log:
Jul 27 04:55:11 xxx kernel[0]: No interval found for . Using 8000000
I am presently on Mountain Lion, and had the exact same behaviour with Lion.
Any ideas would be greatly appreciated!
Thanks,
Ramit

Correction - it is a PS/2 keyboard that I connect to the USB port using a convertor.

T mobile broadband stick not working after lion instal

T mobile broadband USB stick not working after lion install

No s#!t batman.The point is a mac laptop is ment to be mobile and for it to be mobile you need a mobile broadband stick so when a new op system lion is released don't you think it would be one of the first items to be checked for compatability.with snow leopard the same problem took months before I could use a broadband stick,there is no lion connection manager software available right now until someone decides to wright it, so does anyone have a usefull fix i can use ?

4530s DC CARD or USB BOOT not working even if it has this option in bios

i just posted a message but i think it's in the wrong section..
http://h30434.www3.hp.com/t5/Other-Notebook-PC-questions/sd-card-boot-and-usb-boot-not-working/m-p/9...
Hi, i just got a HP ProBook 4530s , I5 processor, Intel HD 3000 , i have a problem with it, i can't boot on any usb or sd card, i tried all linux versions i could find and also some live windows and bartPE, on my sd card i get the "Disk read error" as soon as i choose the booting device and on usb it goes a little bit further i can see the linux logo some processes starting and then same error related to write on disk, the sd card and usb are not in read only mode and on my other laptop a older one 6730s everything works...
Also all the usb and sd card work perfect in windows, when i boot from internal HDD.
Is there a fix for it?? Or can anybody that has this laptop test if it works booting from usb or sd card, maybe it's a problem with this unit..
i have tried all available bios verions and various usb devices but as i said the usb sticks all worked on my other laptop but not on this one.
Oh and also is there a bios option to stop virus check on boot? as far as i could test that is the only option in bios that is not there and i can't test with it ON/OFF.. any help would be apreciated because i can return the laptop for 30 days and i allready have it for one week. and i really need this option to work.
PS - sorry for my bad english but i'm from Europe

Yes, I've tried this. I pulled the power cable, waited two minutes, hit the CMOS button, and also removed the battery, and waited another minute.

Windows 7 (Ent) Sp1 on server 2012 R2 HyperV, RFX USB redirection not working

Hello,
I currently have windows server 2012 R2 with HyperV installed. I have built two virtual machines. A windows 8.1 and Windows 7 sp1. Both are enterprise editions
For RemoteFX the hypervisor is using a Zotec GTX 760 GPU. It recognizes it and uses it to apply remoteFX adapter on my Windows 7 Sp1 VM.
As you are aware I do not need to use a GPU to enable RFX on my Windows 8.1 it can do this without the need of a GPU.
Using an RDP client( v8.1) I can connect to my Windows 8.1 VM with a USB headset,memory Key or a printer and they all enumerate on the Virtual machine. The driver for each device installs
and I can use the device without any issues.
However this issue lies with the Windows 7 SP1 VM. I can connect to it via RDP( Same client) but I cannot redirect any devices to it. I have installed the latest integration services available on the VM. I have ran all updates available.
Because I have ran all updates the rdp version on the VM is running v8.1.
Previous to installing the updates USBr still was not working
I have enabled the following group polices under remote desktop services on the Windows 7 SP1 VM :
RDP 8.0 -- Enabled
Configure RFX -- Enabled
Is there a known issue with USB redirection not working on a Windows 7sp1 virtual machine hosted on server 2012 Hypervisor ??
Many Thanks
Brian

Hi,
According to the log above, I found that we run the script on both Server6 and Server7. Errors as below:
Server6: Conversion is not supported in restricted language mode or a Data section.
Server7: Couldn't figure out valid servers from the specified destination scope. Check your parameters and try again.
Since we can only run the RollAlternateserviceAccountPassword.ps1 Script on CAS server, the script not works well if Server6 is MBX server.
For Server7, based on the error message, it seems you still have no right to run the script/cmdlet.
Please add your account to Organization Management Role group(ADUC->domain.com->Microsoft Exchange Security Groups) to test if possible.

I tried to re-plug usb devices but notting happens... Still not working
But after the win-8.1 shutdown, if i switch off PSU power button, watting ~1 munute for discharge.
After power up PC and boot with windows 7 all usb devices works normaly.
I checked all internal connections. 2 times disassembly all hardware and re-built system, nothing changed.All windows updates and latest drivers installed.
I'm sure other H/W is OK, but I thnik this mobo have a fault.

SA30 USB do not work after reinstall, please help!!

Hi, my SA30's USB do not work at all after reintalling, I do not have the original CD with the laptop as it is a gift from my mate.... I couldnt find the driver from the website, please could anyone help me???
I could use the USB mouse but when I plug the external hard disk in, it has no responses, I tried to search for new hardware, it couldnt detect it. Any information would be appreciate, cheers.

When you instll another OS than the recovery OEM OS you have to install the drivers and tools in a right order!
This order is on the Tools & Utilities CD in a html file! When you follow these order all hardware should be detect!
Also you can go to http://eu.computers.toshiba-europe.com and download the drivers

V570 - USB Ports Not Working

Please forgive me if I posted this in the wrong section! First thread!
Recently, three out of four of my USB ports decided to stop working. The one USB port that works is a USB 2.0 port that is located between the microphone jack and the DVD drive. There is also a eSATA / USB combo port. The eSATA portion works fine, but the USB does not work. At first I suspected that the USB controller was probably starting to fail. I don't understand why all but one USB port functions properly.
I have tried reinstalling the chipset drivers, updated my BIOS, and I tried to see if the ports are recongized in Linux. None of those work. I also checked the ports to make sure there are no bent pins. My warranty period just ended so I was wondering what I can do now. I don't mind opening up the computer, as long as I know what to look for.
Thanks in advance!

hi idaggerpwn,
The USB board must be bad. Try to re-seat the cable from the USB board to the motherboard and check. If this doesn't work, check if the USB ports are somehow disconnected to the PCB. If they are, you will need to hire an a technician with board level soldering skills to reconnect them or you can contact lenovo for service to replace this part. (fees may apply)
Check page 78 (see #10) of the hardware maintenance manual (HMM) for the USB board location. To access the USB board see page 53 of the HMM.
Best regards,
neokenchi

Hi,
What about if you try to install drivers from your product's page?
http://uk.msi.com/support/mb/Z97-GAMING-5.html#down-driver
And when exactly it starts to fail to work? Did you try to have OS just installed, restart it and see if it works then? Are you able to determine which driver installation causes USBs to stop working?
thank you
i just remove USB3 controller driver and work
thank you all :D

Touchsmart TX-2 fingerprint scanner and USB ports not working

Hi everyone,
Please forgive me if this is in the wrong spot.
Just sent my laptop (Touchsmart TX-2 1015au) off for a warranty fix - told them the USB ports weren't working on Windows 7, 64 bit. It came back wiped, running on Vista 32 bit and.....with the USB ports not working.
I figured I'd try to get it working because I need my laptop for uni and can't send it back right now. So I clean installed Windows 7, 64 bit again and its still not working. Did the standard open device manager and uninstall everything under the usb tab. All that has resulted in is causing the fingerprint scanner to stop working (being told that it is not connected) and still no working USB ports.
All advice really welcome and very much appreciated!
Thanks in advance

Hi:
Should be no problem to get W7 32 bit to work on that model.
Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
Your model uses the Intel HD graphics driver only.
The first driver you have to install is the Intel chipset installation utility and then reboot.
http://h20565.www2.hp.com/portal/site/hpsc/public/psi/swdHome/?cc=us&lang=en&sp4ts.oid=5359407&ac.ad...
Audio: Accept the agreement. Download and install the first driver on the list.
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownT...
If for some reason, the Intel HD graphics driver from that model does not work, then use this one...
