Power Noise From USB

I noticed something interesting while listening to iTunes. In between songs, I noticed a lot of noise. After troubleshooting, I have found that the noise was coming from a USB cable, used to hook my printer. I could hear all weird sorts of noise as the printer was doing some print operations. When I unplugged the power going to the printer, the noise went away. I am wondering if there something I could put in between the USB cable and the port on my MacBook to eliminate the noise. Or perhaps a different type of USB cable.

Is the music going to outside speakers, or internal ones? If it's external, my guess is that you're using some unshielded USB cables. If you get some shielded ones and run them as far away from the speakers as possible, you might cure this issue.
Also cheap speakers just don't do well with electronic interference.

No power charging from Usb

No power charging new iPad from USB ?

I have no idea why the iPad would not be charging with another power adapter but will charge thought the USB port on your computer. Try rebooting the iPad.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up
If that doesn't help, I think that the next thing that I would try would be to reset all settings. Settings>General>Reset>Reset all settings. If you do this, all device settings will have to be re-entered and tha does take some time to do.

Bad noise from USB audio input

Using Roland UA-30 USB audio input device with ibook 1.2ghz with Logic Pro 7.
Getting nasty noise. Any other ways of getting audio into my ibook without the fuzz and buzz ?

ok first of all to help your ibook 1.2ghz's power, upgrade your rams, atleast 1.5GB, safer side will be 2.5GB
2) get the pro app if you haven't done so
http://www.apple.com/support/downloads/proapplicationsupport30macosx1039.html
3) I was gonna say get the latest update for the UA-30 but it comes with OSX
4) try not to set you buffer size too high, try around 128-256 or better 512
5) make sure your cables are good/pro cables
6) record using other applications to see if its logic or just the card itself

Can HP Pavilion dv5000 series notebook power on from usb keyboard?

My HP Pavilion dv5000 series notebook has a dead monitor. Otherwise it works fine. I've attached an external monitor, usb mouse and keyboard. I'd like to keep the cover closed. Is there a way to power it on without opening the cover to access the power button.
Thank you

windows failds to start. a recent hardware or software change might be the cause. to fix the problem :
status : 0xc000000f
Info : The boot selection failed because a required device is inaccessible.

IPod Nano (4th Generation) switches on when connected to USB power - shows Menu & hangs (unresponsive to click wheel) - deems off after 5-sec - Switches off after disconnecting from USB Power - syncs with iTunes - Tried 5R's - Problem still persists

1. The iPod Nano (4th Generation - 8GB) switches on, only when connected to USB power by showing apple logo and displays Menu options thereafter..
2. However, I can not access Menu as it is unresponsive to click wheel. As a result it is inaccessible to any further use,
3. NOTE: it displays "Battery Fully charged" icon on the screen without any "Lock" icon.
4. After 5-sec to 10-secs the screen deems off.. i.e. goes to sleep mode.. And thereafter would probably remain like that (sleeeping) for eternity!!!!
5. It Switches off after WITHOUT DISPLAYING any Apple Logo immediately after disconnecting from USB Power.
6. In other words, it can be switched on only through USB power in spite of battery being fully charged.
7. Interestingly, it syncs with iTunes. It is recognised in iTunes (Latest version 11+).. Displays on screen all commands Like.. syncronising, connecting, connected,
8. Allows to add Music, videos like a normal ipod & displays all status information in iTunes.
9. Read Trobleshooting & Tried all 5R's. Registered, Resetted, updated & Restored to iOS 1.0.2
10. It is now displaying to select Language in place of Menu options, with no access through click wheel, centre button whatsoever... Problem still persists
KINDLY GUIDE ME THE SOLUTION. APPRECIATE YOUR RESPONSE in advance...

"I get the feeling that this is a software issue that could probably be solved quite easily"
Since you have already tried all the normal troubleshooting solutions, take the iPod to your nearest Apple Store for a *proper diagnosis.* The staff there will be able to confirm if your problem is software or hardware _*at no cost to you.*_

Is normal at power mac make noise from the optical drive?

when I power , the mac make some noise from the optical drive , I guess, This is normally? this noise just appear when I update my Mac to Mountain Lion 10.8.2
Thank you everyone!

Normal, normal, normal. Don't know the reasoning behind it - I suppose the MBP is trying to load anything that might be in the drive at startup. Had me confused for awhile, way back when...

The Power Direktor 12 can not found a camera from USB

I have load Power Direktor 12 Install Win 7 64 bit oll ok but when i go over vidio Grubber in USB the Programm found nothing !
A other Programm from my found this . What can i doit with Power Direktor fre USB ?

I'm not sure that this makes sense. Windows is made aware of the existence of the certificate, but does that really mean it's in the Windows keystore that you're looking at? Shouldn't your Java code be looking straight at the device? via PKCS#11?

Mackie Control Pro drawing too much power from usb?

I have a Mackie Control Universal Pro connected to my 2.8GHz Intel Core 2 Duo with 4GB rom, running OSX 10.5.4.
When I first hooked up my Mackie Control Pro (about 1 year ago) it worked perfectly. A bout 2 months ago my computer wouldn't recognize it anymore. I keep getting this message telling me the device is drawing too much power from USB port and due to that it will shut down that specific port.
My MCP is plugged to the electrical outlet and shouldn't need to be drawing power via the USP. I tried disconnecting all other devices hooked up via USB and Firewire beside the keyboard and mouse but same massage keep coming.
I checked the MCP to make sure the electrical wire was plugged in properly and supplying it with power, I also tried hooking it up with different USB cables via different ports but problem still there.
Can anybody help me out please this is starting to be a big head ache. Any help would be great.

Not 30 seconds after submitting the question I did just that. I felt stupid not thinking of that simple check. Thanks for the quick reply. It worked just fine with another cable. It appears we need a new cable for my daughter....
Thanks again.

Why do i get a usb power warning from my retina display macbook pro?

When home, i connect my 13" retina macbook pro to my thunderbolt monitor. I have my ipad and iphone thethered to the monitor via usb for charging, sync and so on. I frequently get warning messages stating that my "usb devises are drawing too much power your my computer, one or more of your usb devises has been disabled". This is just one more delightful little problem I've had since acquiring a retina display macbook and/or updating to 10.8.4......i could write a book! Anybody else experiencing this issue?

I don't have an answer for you. What you say sound right but is the TB display really supplying power to the USB ports on it or are they being powered from the notebook? I don't know as I don't have either a TB display or a retina MBP.
About the only thing to do is take it all into a apple store and let them figure it out. That is why they are there. To deal with the inconsistencies and problems with Apple devices.
Best of luck to you.

Is an adaptor cable available rouse to charge a Mac Pro from an auto, either a power point or usb?

Is an adaptor cable available to charge a Mac Pro from an auto power point or usb?

I'm having a very similar problem.
I've got a 2010 iMac that I've got hooked up to my Pioneer Elite via HDMI cable using the Moshi adapter.
It's been working great for months, but today the audio began dropping out -- a fraction of a second, every six seconds or so.
I installed the latest Snow Leopard update today. Does anyone think there might be a connection?
thx!

WD Legacy External Hard Drive "Draws too much power from USB"

I have a nice MacBook Pro running Leopard, a year or so old and I've never had any issues with it. I used a WD Legacy 250GB External Hard Drive for Time Machine to back up all my stuff. It has its own power source, and the USB cable works fine because I use it with my printer all the time. However, even with both the laptop and the hard drive plugged in, my laptop automatically disconnects the hard drive because the "USB is drawing too much power".
It didn't happen when I initially backed stuff up on it, and it plugs in and works fine with a desktop. Is there any way to disable the automatic disconnect for drawing too much power through a USB? I don't understand how that's even possible because the external hard drive has its own power source, and I just want my stuff backed up. I could care less if it ***** the charge out of my laptop for a few minutes if that means it will work. I've considered getting a powered USB HUD, but wanted to get everyone else's opinion first. Thanks!

Contact the manufacturer. I think the power pack for the drive is not functioning properly.

MSI Z87-G45 Gaming, sound from USB mouse?

Hi!
I have some issue from my new computer, see spec below.
For the information I have a MSI Z87-G45 motherboard.
I have some sound that occurs sometimes (specially during the first 2-5 minutes) when i move the mouse around.
It occurs as well sometimes when I been using the computer for a while, basically random just more frequently at the start-up.
It's hard to know from where the sound occurs, could be PSU but today I read something on another forum about the motherboard I'm using:
- Higher sound quality using USB, thanks to special adapted current power.
So i wounder if this can be the case? Is that the reason why i get this noise from inside the computer?
Is there some way to disabled this "feature" in BIOS?
Greetings

The sound sounds like the old mechanics hdd kinda.
It comes inside the computer, not the speakers.
My feelings is that it can be the PSU as well, just wanted to check this first, since it most often comes when i move my mouse.

Clicking noise from back-ups

Since replacing my G5 with a new mac mini I hear frequent clicking noises from the APC Back-UPS that I have it plugged into. The only obvious difference is that the mini has an ungrounded two-prong plug while the G5 had a grounded three-prong plug. The clicking noise consists of two clicks in succession, the second one slightly lower in pitch. This occurs at random intervals but also in response to anything that I'm doing on the computer such as opening or closing an application, resizing a window, visiting or exiting a website, etc. Occassionally it will happen when the computer is asleep in which case I will hear the fan running briefly in the mini although the monitor doesn't wake up. When this happens I will often see the internet activity monitor light flashing on my dsl modem. I don't know if these noises are a sign that something isn't working properly or just an annoyance. In either case I would welcome suggestions on how to stop it as well as any ideas as to what might be causing it. The APC unit provides battery back-up power in the case of a power outage and surge protection. I submitted my question to APC support but got no response. I also talked to someone at AppleCare and he had no idea what was causing this and wasn't even sure if he knew what I was asking about. However lots of people use back-ups units so someone out there must have experienced this phenomena besides me.

I checked that box but wasn't around the sleeping computer long enough to tell if it made a difference. I plugged in a lamp with a dimmer and turned it up and down with no effect. Then I had an idea. I'm going to wait a couple of days before marking this as definitely solved, but here's what happened:
The UPS has three outlets marked "controlled by master." Anything plugged into these gets it's power turned off when the computer is sleeping. I had long ago moved the peripherals to the other outlets because I didn't like having my computer and monitor wake up whenever I turned on the printer just to use the copy function. Near the power button on the UPS is another smaller button with a graphic symbol. If you hold this down for a few seconds it turns off the "master enable" function. After I did this the clicking stopped.
This still leaves some unanswered (though no longer important) questions: Why was this an issue with the mini but not with the G5? Why was I getting clicking noises in response to doing things on the computer even with the usb connection to the UPS disconnected? Why was I also getting them even when the computer was asleep? One possible factor is the usb hub. The old one was on a pci card, while the new one is external with a power cord connected to the UPS. Another factor may be the ungrounded power plug on the mini vs. the grounded one on the G5. At any rate it looks like the problem is solved, at least for now.

Lot of noise from laptop audio output

I'm getting a lot of noise from the audio output of my Macbook Pro (early 2008) OS 10.8.5 when I connect an external firewire 800 drive that uses a power cord. I get more of the same noise when I connect an external video monitor. The noise is a digital hashy and whiney sound that modulates sometimes as what on the screen changes. If I use my Focusrite Scarlett interface the noise is amplified to the point that I can't work. The noise starts when the drive's power cord is plugged in. If I work off a pocket USB drive there is no noise. This is my work around for now. I'm using a power strip that has noise filtering. I have 2 different studios and I get the same noise in both. I've done a lot of trouble shooting and have narrowed the problem down to connecting a drive with a power cord to the computer. I have tried different drives too with the same result. Is there any hope of fixing this?

Can't say I've ever had any noise when starting the unit up over optical - if your DAC is designed for stereo only then it may be causing noise by attempting to play the 5.1 startup video's audio bitstream which is dolby digital encoded not stereo.

Static Charge Icon with cycling noise from harddrive.

The apple logo appears, there is a repetitive cycling noise from the harddrive and eventually the sad face icon appears. If it is plugged in my USB port, a static battery icon with a lightning bolt appears. It stays there for about three minutes and cylces through the apple log/sad face again. If I plug it into a wall charger, no battery icon appears, just the apple log/sad face & noise.
None of the 5 R's helps.
This is my third unit through warranty

The Sad iPods icon, clicking sound or folder with an exclamation mark are the toughest problems to deal with, and must do a Restore in order to fix it. However, when your iPod is showing this icon, it is probably too late for your computer to recognize the iPod.
1. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
2. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
Still can't see your iPod?
Several things could keep iPod from appearing in iTunes or in the Desktop/Finder when you connect it to your PC/Mac. The most likely causes are listed below in logical order. Check from the top of the list to see if that is what's keeping iPod from appearing.
3. Try to wait 30 minutes while iPod is charging.
4. Try another known-good FireWire or USB through Dock Connector cable.
5. Try another known-good FireWire or USB port on your computer .
6. Try to disconnect all devices from your computer's FireWire and USB ports.
7. Windows users having trouble with their iPods should locate a Mac user. We've found that in many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
There are also some cases being reported that some unrecognized iPod being able to be erased with Linux, then reconnect the iPod with the original computer and do a Restore there.
8. Try to do an Erase (Disk Utility) on a Mac computer or a format with a PC (Disk Management tool) but ensure you choose the right Drive (your iPod not your Hard Disk of your computer). You may need to plug and unplug your iPod with the computer for several attempts, and switching around Format and Restore, and hope out of sudden, it will get recognized.
9. Diagnostic mode solution – which I copied from a thread of a post from thinktwice
“Then I cam across this special Diganostics Mode that you can get to by resetting and then while the Apple is showing pressing the Select and backwards keys simultaneously. It bring up and weird Diagnostic utility witha a abunch of tests. Here is what I did
- I tried the 5in1 test and got and error on Firewire.
- I did the HDD R/W and surprisingly it passed.
- I went on to the HDD scan. This supposedly tkaes acouple of minute so I waited. I think 4-5 dots appeared then nothing. The iPod started to get hot. THe disk was spinning away. After a while the battery got very low. THis test chews up the battery. So I escaped out by resetting and went to connect it to a power source.
My USB was dangling out of my computer and I was too lazy to get the Firewire AC adapter thing going so I connected expecting the whole lockup thing with iTunes. Surprise. IT was recognized immediately and has been working like a champ. So go figure.
Details on Diag mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/index.shtml
10. Let me ask you a question, if an iPod with no iPod software with it. When your connect it with a computer, what would happen?
Yeah, the computer will treat it as a fresh external hard disk, which will get force mounted, the computer will ask you to format the iPod. It does not really matter the format is completed or not, the key is to erase (or partly) the corrupted iPod software on the iPod, after that the computer will recognize it.
Once it has been completed, eject your iPod, open the iPod updater and interestingly, you will able to do the Restore this time.
Base on the above, that's why I suggest Windows users who experience trouble with their iPods should locate a Mac machine or vice versa. PC computer will not recognize a Mac formatted iPod, but it will get mounted in an attempt to format your iPod.
11. Put your iPod in disk mode and plug with a computer, and have a boot of your computer using the Mac OS or XP startup disks, hope that your iPod will be seen on Mac's Disk utility and allow you to do a Erase there. Or, under the XP, you will be able to find your iPod there for you to do a Restore.
But, if none of these steps address the issue, your iPod may need to be repaired. You can arrange for service at the iPod Service Website.
I have just read an interesting solution about the Sad iPod, it does make sense but the warranty will be waived once you open the iPod, I would not do it myself as I am not good on doing this
