Latest iMac: USB power requirements unclear, Microsoft USB game pad stopped working

Hello,
I am sorry that the cut and paste information is in German.
I am a long time Apple iMac user and used the Game Pad since years with no USB power issues.
Now, I have just received my late 2014 iMac with Maverick OS X.
Hardware-Übersicht:
Modellname: iMac
Modell-Identifizierung: iMac15,1
Prozessortyp: Intel Core i7
Prozessorgeschwindigkeit: 4 GHz
Anzahl der Prozessoren: 1
Gesamtanzahl der Kerne: 4
L2-Cache (pro Kern): 256 KB
L3-Cache: 8 MB
Speicher: 16 GB
Boot-ROM-Version: IM151.0207.B00
SMC-Version (System): 2.23f11
Ever since, I cannot use my Microsoft USB Game Controller any more.
Controller:
Produkt-ID: 0x028e
Hersteller-ID: 0x045e (Microsoft Corporation)
Version: 1.14
Seriennummer: 075841A
Geschwindigkeit: Bis zu 12 MBit/s
Hersteller: ©Microsoft Corporation
Standort-ID: 0x14600000 / 16
Verfügbare Stromstärke (mA): 500
Erforderliche Stromstärke (mA): Unbekannt (Gerät wurde nicht konfiguriert) <--- Device unknown, and not configured. The power requirements are unclear.
What can I do to get the USB controller accepted again? I have a 3rd party OS X driver that does work for me. I'd assume, this issue is at the HW layer, during boot-up and initial hand shake, not a SW driver's issue.
Sincerely,
Michael

I guess I should have read the forum first. I zapped the pram and everything seems back to normal. Sorry for not trying this 1st. Issue solved.

USB Ports Randomly Stop Working

I have an HP Pavilion dv6 Notebook with Windows 7. All of the ports, 2 2.0 and 2 3.0 ports, began to randomly stop working. My mouse light would still light up, but the mouse wouldn't work. If I rebooted the entire laptop, all of the ports would come back on for a short period of time before they randomly shut off again. They will also come back on for a short period of time if I close the lid for a few seconds and reopen it. However, lately, the 3.0 ports have stopped working entirely and the 2.0 ports stopping is becoming more frequent.
The first time I noticed this was when I was testing a micro usb cable (it has stopped charging and I was testing whether it was the cable or the wall adapter). I plugged the cable into one of the 2.0 ports and it gave me a USB surge warning. Other than that, I haven't received any notices. The drivers are up to date. I have uninstalld the root hubs multiple times. I have tried all kinds of Power plans for the laptop. Nothing works. The USB ports still stop working, and it's becoming increasingly more frustrating.

Hello Abby_Renee,
With the USB 3.0 port not working, and your 2.0 port working intermittently, I would suggest the following document Troubleshooting USB Connections (Windows 7) for troubleshooting.
In this document there is a specific option for USB 3.0 ports stop working, which would be the best steps to follow for your 3.0 ports. Now for the 2.0 ports, I would suggest USB device not detected by Windows (no device name in device manager), or the other option is USB devices are detected by Windows but are not working properly. The last two options are dependant on the specific errors you are experiencing.
Please let me know the outcome of the troubleshooting steps.
Good Luck!

After i updated to mavericks, my usb ethernet adapter stopped working.

I'm not sure why, but when I updated my software to mavericks, my USB ethernet adapter stopped working.

I'm using that adapter:
http://www.edimax.com/en/support_detail.php?pd_id=445&pl1_id=5&pl2_id=26
After I updated to Mavericks, I installed the driver in this page, but it didn't work. Then I googled "AX88772" which is my adapter's part no. or something like that, and I installed that one:
http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97
I wasn't expecting that work but that did work. So, I think the solution of the problem is finding the right driver. I hope you solve your problem too.

USB audio DAC stops working after suspend

I didn't update my mediacenter running arch for a few months so I figured i'd reinstall it because of the filesystem, /lib and grub changes. Now after reinstalling I'm running into the issue that my USB audio DAC stops working after a suspend.
After a suspend speaker-test gives me the following error:
[user@mediacenter ~]$ speaker-test -c 2
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave
Playback open error: -77,File descriptor in bad state
I've tried replugging my DAC and restarting ALSA, without any success. I have to reboot to get sound again.

What I'm noticing is that after a suspend "Subdevices: 0/1" gets changed to "Subdevices: 1/1".
Any help is much appreciated!

Unless you can find a way to stop XBMC from using your DAC, I would try hunting down the update which broke it and file a bug report with the appropriate project. https://wiki.archlinux.org/index.php/Do … g_Packages.
I suspect it would be the kernel.
Yes I am suspecting the kernel as well. I'll try to change some options in XBMC to maybe get this working, and if not I'll see how far I can downgrade with the kernel. My last installation was a few months old so I hope it broke not that long ago.
Thanks for the help

Why has my USB Superdrive suddenly stopped working with my MacBook Pro?

Why has my Apple USB SuperDrive suddenly stopped working with my MacBook Pro?
Normally I plug it in and insert a CD or DVD and it is immediately recognised, but today it took the DVD, made a 'whirring' noise for a few seconds and then stopped without being recognised.

I have a mac book pro that both USB ports have stopped working one about a year ago and one recently. Is it possible to connect to another one of the other MBP's ports with a cord that ends with a USB port?

Thank you For your time and thoughts!
I went by the Apple Store and they told me that there was a "Flat Rate" repair service for this particular part where they would replace the logic board along with the USB ports for $350. Seems like best avenue. All of this would have been moot but my wifi in the computer also doesn't work so I was using my phone as a hot spot and tethering it to the computer for Internet access when the last port quit. This left me with no internet and no printing capabilities on the computer I use for my business. Basically became a nice paperweight. lol
They will ship it off Monday and I should have it back Thursday!
Again, thank you!

I managed to fix this... here’s what I did:
I extracted the MSDN ISO to my downloads folder
I created an office 2013 config file with logging set to verbose and copied it to the x64 installer directory
I ran the installer and looked in my temp folder (c:\users\rob.henwood\AppData\Local\Temp)
The log file created said “Cannot detect OSE Service”
I found the OSE Service in the setup folder from the ISO
I looked on another machine and found where it is installed then copied the registry settings for the OSE service.
I restarted the machine and found the Office 64 Source Engine service now existed. I started the service.
I ran the Office installer again and it all worked OK!
Steps to fix:
Create a folder for OSE
C:\Program Files\Common Files\microsoft shared\Source Engine
Copy the OSE.exe file to that folder
Open the OSE.reg file (shown below) and apply the registry settings in that file to your registry
Restart your machine
Open services (services.msc) and see that Office 64 Source Engine is installed
Start the service
Try installing Office 2013/Visio 2013.

Microsoft Setup Bootstrapper Has Stopped Working when Trying to Install MS Project Professtional 2013

I cannot get the trial version of MS Project 2013 to load onto my computer.
I keep getting "Microsoft Setup Bootstrapper Has Stopped Working" error message when attempting to download.

What operating system are you attempting to install to?

Microsoft setup bootstraper has stopped working

hi, when i am trying to install microsoft office professional plus 2013 in my windows8.1 based system pc , i can not installed it. there shows a massage " microsoft bootstraper has stopped working" i tried to installed it several time but
it shows same massage . please help me.....

Hi,
"Microsoft Setup Bootstrapper has stopped working" is a generic error for Office installation. It could be caused by lots of reasons, thus the troubleshooting of this issue can be tricky.
You might first check the setup log file and see if there is anything useful there. If you would like us to help analyze the logs, you can send the log file to this email account:
[email protected] and inform us here (the email subject should be the link of this thread).
Also, to troubleshoot the issue, I would sggest we try following steps:
If you have any trial or beta version of Office 2013 ever installed on your computer, please try to run
Microsoft Fix-It tool
to remove any possible traces which might cause the problem.
If you have enabled any real-time scanning feature of your antivirus program or firewall application, temporarily disable them, then try again.
Hope this helps.

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office
programs.

Microsoft Setup Bootstrapper has stopped working, cannot install

We have acquired license for MS Office Pro Plus 2013. and downloaded SW_DVD5_Office_Professional_Plus_2013w_SP1_64Bit_English_MLF_X19-35976.ISO
to be installed on my 64bit system. but i am unable to do that as it reaches half way and then shows below mentioned message,
Microsoft Setup Bootstrapper has stopped working
I have tried several suggestions like cleaning registry, disabling firewalls, antivirus, stopping print spool, stopping services etc.
please help me get thru this problem.

Hi,
There are many reasons for the happening of this problem (Bootstrapper has stopped working), like a beta edition of Office exists, antivirus or firewall program or other security software, etc.
Have you ever attempted to install other Office products on this machine previously? Remnants of old Office installation is a common cause of this issue.
I see you've mentioned "cleaning registry", not sure how you did this, the recommended way to remove any traces/remnants for the old Office instance from your system is to run
Microsoft Fix It tool.
After this, please try again in Windows clean boot and see if issue persists:

Microsoft bootstrap manager has stopped working in my Lenovo G560!!!

I recently downgraded my Lenovo G560 to Windows 7 Ultimate from Windows 8 Pro (Werfault.exe error continued to reoccur even after clean installs). However, after reinstalling my drivers and programs, I cannot install any Office programs. I have tried installing Office 2013 and it encounters an error; Microsoft bootstrap manager has stopped working to be particular. I re-tried with Office 2010 and the installation fails to complete citing an error. These two office packages have previously worked in my G560. Used Office 2010 for a while before installing Office 2013 which I have used for two months. Does the recent install of Windows 7 Ultimate 64 bit have anything to do with it? How can I fix it? Any help will be appreciated.

I'll try that in a few days. I'm currently on the road. Didn't carry my external HDDs with me. Will try it then let you know.

My usb ports have stopped working on my iMac

Thanks

Hopefully the SMC reset works otherwise it may be a Logic Board issue.
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.

USB ports have stopped working on my 975 power up platinum

For some reason the usb ports on the mb & the front of the case antec p160 have stopped working, I have not added anything new or removed anything, the firewire ports are still working though. I have tried removing the usb root hub restarting the pc and letting windows reinstall the driversbut it does not make any difference. Does any one have any idea what the problem my be.

He means what is in the thread labled "If you're having problems with USB ports, read on... "
The USB issue has followed several boards. Here is a quote from a post I've made on the subjetct.
Quote from: Frankeputer
Check to see if there is a wire running from your Front USB ports to the #10 slot of your USB block which connects to the motherboard header.
USB connector block layout which corresponds to the pin layout on boards with the Intel spec for USB. Do not cut the pin on the MOBO. You are removing/cutting the wire to the connector block from the case.
2 4 6 8 10(this wire, #10, not needed)
1 3 5 7 9(filled/key)
If you find a wire leading to the #10 spot on the block, remove that wire. My block has tabs so that you can pull the wire out, or you could snip/cut the wire leading to that position--if you cut the wire, be careful to cut the correct one and cut it in such a way that it may be repaired if you make a mistake. Make sure you wrap the wire, the exposed end/s, you remove/cut with electrical tape so as not to accidentally cause a short. I actually folded the wire back and wrapped it.
2 posts to read--Here and Here.
This seems to be a common issue involving many different case manufacturers. I don't know how it applies to other MOBO manufacturers, but in these forums it is not limited to a specific MSI model or supported chipset(Intel or AMD).

My Mac USB keyboard has stopped working

Hi,
I have a less than 6 month old fully loaded iMac 3.4 ghz i7. Overnight my USB (alphanumeric keyboard has stopped working. Had to dig out a wireless keyboard from another mac to login. The tried unplugging and moving the USB. ( All USB ports works and are powered up with other devices ) No change. Tried full system reset with power cord removed for 5 minutes, no change. Tried it all twice, no cahnge.
Typing this on wireless keyboard and hoping someone can confirm if Mac has pushed an update that forgets about the keyboard or if there is known issues with the usb wired keyboard that means they have suddenly got a life of less than 6 months?

Not any updates I know of, but if there were Software Update would offer them. Have you tried and SMC and PRAM reset - sometimes sorts out odd issues?
