Does an ADC Adapter Power Monitor USB Ports?

I'm planning to pick up a Mini in the near future, and was hoping to squeeze another year or two of life out of my Cube's display. Was curious if anyone knows whether any of the various DVI-ADC Adapters (Apple's or a third party's) supplies the extra power to the monitor USB ports that is required to drive cube speakers?
It'd be a nice bonus (and extra reason not to buy a new display right away) if I got to keep using my Cube speakers with a Mini.

If you purchase Apple's adapter it should do everything you are looking for.

"iPad not charging Connect to a power adapter or a USB port on this mac to charge" Maverick issue!

Ever since we updated to mavericks our deployment of 60 iPad's flashes "iPad not charging Connect to a power adapter or a USB port on this mac to charge" on the screen every time one is plugged in. It is a false alarm because the iPad does in fact trickle charge and it does update the device like it is supposed to. At this point it's more of an annoyance then an actual problem. However I would like it to stop popping up every time one is plugged in.
Does anybody have any ideas to stop it?

Your computer USB port typically provides only 2.5W of power. iPads require 10-12W of charging power. That's why you get the "Not Charging" message. However, the iPad is charging, but much slower. There's no way to stop it.

While charging my ipad when i plugged in the adapter, the adapter and the usb port gets very very hot... Is this normal? I replaced my ipad and adapter but the problem still exist.

While i charge my ipad with adapter the adapter more specifically the internal round cell of adapter and the usb port becomes very very hot... And ultimately my ipad back starts heating a bit. Is that normal?

Take your charger, cable & iPad to an Apple Store for evaluation.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Apple USB keyboard does not work with one internal usb port

Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
Guillaume

I'm facing the same problem, found any solutions ?

Zapping the pram may work or just restarting your computer after repairing your desktop.

U3011t - Not enough power to USB ports

We are working with a U3011t and before this past Friday all the ports on the monitor worked. After doing re-imaging the computer, I am now receiving an error message that states there is not enough power to supply the USB ports. Any Ideas why this is?

The monitor USB hub is simply a receiver when the USB upstream cable is connected from the bottom of the monitor to a USB port on the computer.
The monitor USB hub should appear in the Device Manager. When I connected the U3011 USB upstream cable to my Alienware M18x-R1 blue USB 3.0 port, the Device Manager- Universal Serial Bus controllers added =
Renesas Electronics USB 2.0 Hub
Renesas Electronics USB 2.0 Hub
USB Mass Storage Device
Reconnect the monitor USB upstream cable to the monitor port. Then, connect the other end of our monitor USB upstream cable to every computer USB port and re-test. Also, test the monitor on another computer. If available, test another USB upstream cable. The ones from any printer will work.

B&W G3 chimes, black screen no boot no power to USB ports.

My precious situation:
I have a B&W g3 that has been upgraded to a 600mhz G4. It has been workin g well for several years now. Yesterday I booted into OS X 10.4.11 and it had a kernel panic. I tried restarting to no avail. Everything powers on, the fans the optical drive and the hddrives. The power button is green but there is no chime and the screen is black. There is no power to the USB ports so I can't use the keyboard to flash PRAM or boot into open firmware. I've tried the CUDA and taking out the battery. Any other suggestions would be appreciated.
Since then:
I couldn't resolve that situation, so I got another one at a local thrift store and swapped in all my pci cards, ram and hdd from the old one. It was working awsome until yesterday. Now the same situation as before. I know what I did wrong this time, but don't know how to resolve it. What happened was I went into start up disk in preferences and chose Mac OS X hdd as start up disk and restarted. Before it was done booting I shut it down with the power button on the front and now this. This time though it does chime when I turn it on. What should I do? I cannot use keyboard commands as there is no power to the USB ports.

Do you have the original bootable Mac OS CD or DVD that came with the machine? I have no experience with the Blue&White G3, but had a beige desktop model a long time ago. Whenever I had some strange boot issues with OS 9 or OS X I was usually able to boot from the original OS 8 CD that shipped with the machine. I could then run disc utility to verify and repair the main internal drive and then try to reboot.
Booting issues are tricky, because you don't really know if you have a hardware or software problem, unless you have another identical working machine and can swap out parts to rule out what you know is good and eventually isolate what is bad. Going back to the original OS on the optical media and the stock machine with no third-party expansion cards is a good baseline configuation to start out from.

IPod Nano Drawing Too Much Power From USB Port

My daughter plugged her iPod into the USB port of our iMac today, something she has been doing for months and months, and yet this time she was greeted with an error message telling her that something was drawing too much power from the USB port, so my iMac was shutting down that port. I moved the iPod to another port -- same error message. I moved the iPod to another iMac -- same message. So I am confident that the culprit is the device and not the computer. Any ideas on how to resolve this issue? The iPod is an iPod Nano 7th Generation (current model).

My issue has been solved. The USB cable was bad. I am unsure how to remove my question from the forum ... sorry for taking up anyone's time.

IPod Touch drawing too much power--disabling USB ports

Hi there,
I have a brand new Macbook, just picked it up less than a week ago. I've been hooking up my 2nd gen iPod touch to it for a while without any problems, but suddenly I started to get an error message every time I plug it into my USB port:
"*Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.* To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may also have been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."
I've been looking all over the internet for a solution to this and I can't find a thing--it's really frustrating since this laptop's brand new and I have no other way of charging my iPod.
My laptop is plugged in while I'm doing this. The error message is instant--it seems to pop up before I've even inserted the USB cable all the way. Also, for what it's worth, I just did a test and I get the error message just by plugging the USB in, even if it's completely unattached to anything.
Thanks, looking forward to a solution.

Does the apple ipad2 have a usb port

Does the ipad2 have a usb port?

Yep the camera connection kit (as per Swebbie and Barry) is the way to go. £26 from Currys Digital. Have not tried for general files but for photos with the SD adapter that comes with it is great.
But as Swebbie says what did you intend to use for?

DVI to ADC adapter power issue?

Please forgive me if the answer to this is already posted, I searched with no success:
Just inherited the display for a G4 gigabit ethernet model that has an ADC plug (just to confirm: http://www.dvigear.com/education/connectors//adc-m.jpg).
I would like to connect to my unibody MBPro, and I'm assuming I'd be using a Mini Display > DVI adapter, then a DVI > ADC adapter (found a few but not positive they're exactly what I need).
MY QUESTION: since the ADC display was buss powered through the G4, will it still work with my MBPro using the proper adapters?
Thanks in advance!

You need a MiniDisplayPort to DVI adapter

followed by a DVI to ADC adapter

MY QUESTION: since the ADC display was buss powered through the G4, will it still work with my MBPro using the proper adapters?
The DVI to ADC adapter contains a power supply for the display. (That's why it costs so much.) Although this setup should work, there might be problems, since the two adapters might not be completely compatible. See if they will let you bring your display and MBP to the store to try them.

Windows 8.1 Does not recongnize and of the USB Ports

None of the USB Ports work. Anything I plug into any port is not recognized, wireless mouse included.Device Manager - (Other devices), manufacturer Unknown, location on Intel(R) USB3.0 eXtensible Host Controller-0100 (Microsoft).(Code 28)Can't find Drivers What can I do to correct this problem?
Thank you

Hi Steve,
I don't know if you'll feel better but - You are not alone facing the same problems, I am sure that all the power handling in 8.1 is a mess. If I force the comp. to go to sleep mode, after a while it is
not staying in the sleep mode but shutting down autonomously. I suppose there is more hidden bugs.
Tazlam
Isn't your computer just switching from sleep mode to hibernation mode after the amount of time set in your power management settings? This sounds like it, as in hibernation the computer is effectively shut off. This is also intended behaviour.
As you guys, I hope MS releases a fix soon.

More Power to USB ports

is there a way to boost the power supply of the USB ports on the PB G4 15"? Currently these ports are unable to run an external 80GB drive without an external power supply or a Y-cable hooked up to both ports.

I'm not aware of being able to change the PB hardware to do what you want to do. Suggest buying an external case with it's own power supply. There are a number cases for a notebook 2.5" drive, the challenge being to find one that uses a power supply, however, they do exist. You may already know that you cannot boot up from an external USB drive, so if you do get another case, you might consider one that also has Firewire.
Here are some that include Firewire and a power supply:

Low power on USB port for external hard drive

Hi all!
I'm new here and I have some question about my brand new hybrid - HP Envy x2.
Couple days ago i found an issue that usb ports are powered by from motherboard even when tablet with dock is turned off or in hibernation mode. This is problematic when I leave device with plugged usb hub, external HD, speakers (powered from usb port) and mouse. After 8 hours in work when I go back home I saw that battery is about 10-15% lower than before leaving Envy x2. I disabled USB charge mode in BIOS, but after that I have problem with working of my external HD.
When I try to attach hard drive to computer and then I try to turn it on nothing happens - looks like system (Windows 8.1) can't boot. But after immediate unplugging HDD from USB system goes to procedure of starting. I also tried to plug Toshiba HD after turning on my Envy x2 and being in desktop, but nothing happens. Light on HD is blinking, I can hear from it sound like clicking (trying to start?). Also HD is visible in Device Manager but not in My Computer (as additional partition).
I have tried to change boot options in BIOS by positioning of devices (priority to boot from CD ROM, HDD, OS etc.) but did not fixed problem.
After couple of tests provided to found why my HD did not work properely in disabled USB charge mode I know that USB port did not give minimum value of power from supply. I found cable with one plug on one side, and with two plugs on other side (like "Y" type). Then i plugged one end into first USB port, then second end in second USB port and finally - last end of cable to m HD and booooom! It works!
Here is my question: Is there any ability to change that kind of power supply on USB ports? I want to power mu external hard drive from one USB port, not from two. I have USB hub but don't want to use two USB ports (on the opposite positions of docking station) and additional USB cable. I have the most recent BIOS (F12) and all fresh drivers installed on my computer.
Any solutions?

I am not going to take credit for this. I had a similar problem, but all of my USB ports stopped working for EVERYTHING! You were right on track, and here is the final bit of information that you needed: Microsoft Surface tablet External USB hard drives auto-sleep in Windows 8.1 Posted on November 4, 2013 After upgraded from Windows 8 to Windows 8.1 Pro, my SeaGate Expansion 2TB hard drive always runs to sleep mode automatically and then disappears if no file transfers occur. when I try to access its stored files, the File Explorer will be unresponsive. Changing the power options is not working. In Windows 8.1 the external USB hard drives and USB flash drives are configured with a low power state by default. That causes USB massstorage devices auto-sleep or file transfers stop unexpectedly. You could change the hardware ID of USB storage device in the registry to resolve the problem. * Updated to the latest firmware for the device to check if it is fine. * From Start screen, open the Search charm, type regedit, right-click the regedit icon from result, and select “Run as administrator“. * In the left pane of Registry Editor, navigate to the key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbstor * Right-click the “usbstor” and create a key with the following key name: apricorn (aegis padlock) 09840315 buffalo external hdd 500gb 04110105 cavalry dual bay dock 152d2352 diskgenie usb device 09840092 hitachi touro 3.0 4tb usb 3.0 49711015 kingston datatraveler hyperx 3.0 usb device 256gb (dthx30/256gb) 0951162b lacie 2tb usb drive 059f1018 mediasonic h82-su3s2 probox 152d0539 multi-drive enclosure connected 15200551 seagate expansion 2tb 0bc23320 seagate expansion desk 3tb 0bc23312 seagate fa goflex desk 2tb 0bc25071 verbatim store ‘n’ save superspeed 3tb 18a50400 western digital elements desktop 2tb 10581021 western digital my book 2to 10581140 * Now right-click the new key, create a DWORD entry named DeviceHackFlags with 400 hexadecimal value. * Make a reconnection for the device.
