USB over Cat5/6 Solutions or Wall Dock

I'm looking for a USB2.0 over Cat5/6 solution to connect to and charge an iPad/iPad2 (Preferably iPad2). I will be using this solution with the following wall mounting kit:
http://www.premiermounts.com/product.asp?PartId=2164
http://www.premiermounts.com/product.asp?PartId=1793
I've been able to find a few different USB 2.0 over Cat5/6 solutions varying from 150'-330' capability, but they don't seem to have enough power to charge the iPad while the unit is running, ie Gefen (http://www.gefen.com/kvm/dproduct.jsp?prod_id=5529) only outputs 500ma while the USB power supply that comes with the iPAD2 outputs 2A. I also know that there are cables made that combine power from (2) USB ports into (1) device as one came with my external 2.5" laptop hard-drive enclosure but I haven't found them for sale separately and I'm not sure that the iPad2 will charge properly while continuously on with a combined 1A supply (via 2-500ma USB ports).
Any help with my dilemma is appreciated, my goal is to utilize the iPAD2 as an advanced automation Crestron Touch-Panel. I would have no problem with an all-in-one wall dock solution or an elegant looking wall dock where the panel is easily removable by the customer for syncing with a desktop computer. So far I've come to the conclusion that I can power the iPAD2 continuously with the factory power supply or I can connect it continuously via a Cat5/6 solution, but not both.

Have you looked at this system from VidaBox?

My ipod will only charge on the docking station. says it has a full charge but when I take it off the docking station it says battery is low so I've plugged it into the usb and plugged it into my wall outlet but it is still not charging. Help?

my ipod will only charge on the docking station. says it has a full charge but when I take it off the docking station it says battery is low so I've plugged it into the usb and plugged it into my wall outlet but it is still not charging. I'm not sure what generation it is, its an 80GB. Help?

The battery is possibly unable to take as much power as a normal battery. It may need a replacement battery.

USB over current notice and other problems

I have a 17" MacBook Pro (original 2.16 Core Duo) that has a USB over current notice pop up. The pop up says that the USB hub it's attached to will be deactivated. I'm trying to troubleshoot it but can't figure out what's causing it. What exactly does this notice mean? The ports all still work. The iSight doesn't work (not even recognized in System Profiler), and I know that's on the USB bus. Could that be the problem? I noticed the pop up seemed to occur with movement. I've found that I can recreate the USB alert at any time by applying pressure to the bottom case, in the center right behind the RAM cover. This may sound strange, but while trying to figure this out, I was pressing around on the top case to the sides of the trackpad, and when doing so it made a crackling sound. It did this again when I applied pressure and the keyboard and trackpad became unresponsive. Does anyone have a clue? Thanks.

Try http://support.apple.com/kb/HT2090 to see if you can find the iSight problem.
If your iSight is still not recognized in System Profiler, you likely have hardware problems. (That hardware problem could also account for your problem "with movement" and the "crackling sound.") Contact Apple or an Apple-Authorized Service Provider for service. Tell your service provider about all your issues. My guess is that at least some are related.
If you can get your iSight working again, consider the info from these Apple technical articles:

It seems possible to me that an unpowered (or possibly an underpowered) hub could be causing your symptoms. It also seems possible that a faulty power supply on a powered USB hub could cause bus current overload without your knowing that your hub is operating like a non-powered unit even though you have it plugged in to wall power. If you cannot check your hub's power supply, ask you Apple Technician to do it when you have your MBP checked.

USB Over Current Notice on G5 with 22" Cinema Display

USB Over Current Notice on G5 with 22” Cinema Display
I have owned a Dual 2GHz 64 bit Power PC since 2004. In that time, it has performed virtually flawlessly (as in having no major issues to speak of). Now, all of a sudden, I'll be working away and a warning window with a large white exclamation mark in a red octagon pops-up stating: “USB Over Current Notice. A USB device is currently drawing too much power. The port to which it is attached will be deactivated.” The window repeats itself cascading down 3, 4 or 5 times. This will continue to happen even when I’ve disconnected the only 2 USB devices attached to the computer, i.e., an Apple keyboard and a Kensington Expert Mouse (#K64325). Can anyone shed some light on this problem. It is very disconcerting (not to mention annoying). Does anyone have a solution for me (other than “junk the old beast”)? The fact is it still works great with both Final Cut and Pro Tools. Last but not least, I think I’ve narrowed the problem down to my 22” Cinema display. With the computer is attached to another monitor, I’ve yet to have that warning pop up. Is that possible? Could the display be the culprit?

Yes, in answer to your question (BDAqua) my Cinema Display has a ADC connector & USB ports on the back.
Your asking that question brings another to mind. If there are those, who have figured out, wherein the actual problem lies, i.e., with the monitors that have USB connectors built in, why didn't Apple just issue a recall on those monitors rather than having so much spurious and speculative information floating around out there on the internet?
I've just for the first time tuned in to these user forums and blogs only to discover that this is a wide spread problem that has been going on for years. (???) People saying, "Oh you just need to restart the computer" or "it's a bad mouse" or "bad keyboard" or worse yet, "it's your MOTHERBOARD!!!" when in fact it appears to be none of the above. Surely this is something that Apple became aware of long ago. Why didn't they correct the problem raher than letting it persist and making their buying public jump through hoops. I've been an Apple user for many many years. I've spent tens of thousands of dollars with that company from my first Quadra 950 to my MacPro -- I find this very disappointing.
In conclusion, all I can say is, I sincerely appreciate that you've taken the time to respond in an attempt to help. Thank you.

Usb over current detected

I cannot get my computer to turn on all of a sudden. It will get to the blue HP screen then eventually goes black and gives me this error message Warning USB over current detected
Please remove over-current USB device !! System shutdown in 19 seconds, and it counts down and shuts off. Does anyone have any idea what to do??

USB OVER CURRENT NOTICE

I keep receiving this error message in a dialog box, repeatedly; so much so, in fact, that it is affecting productivity: "USB OVER CURRENT NOTICE - A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated".
The only thing attached by external USB is the stock Apple mouse; in fact, this machine is plain vanilla, nothing-that-didn't-come-out-of-the-box stock Apple. I have tried resetting the SMC. I have tried a different mouse. I have tried no mouse. I have tried all the different USB ports in the back. I performed a shutdown and left everything unplugged for half an hour. There isn't any relevant help on Apple's support site.
Any ideas?

I don't know if this helps but...
I have five 24" iMacs in a education lab that keep telling me "USB Current Overload," even though only the Apple keyboard is attached. It seems they starting giving me the message the first time I turned them on. However, after a great talk with an Apple Tech person, we deduced that it must be a driver I installed on the five machines. We came to this conclusion because when I boot the machine from the OS CD, the problem doesn't happen. When I reboot from the hard drive, the message incessantly pops up, even with just the keyboard and mouse (that it came with) plugged in. On one machine in particular, the message pops up so many times that I can barely use the machine.
I have installed two external devices driver's on this machine, a Novation ReMote Compact SL driver and a TC Electronics 24 D firewire driver. I also have "frozen" these machines using DeepFreeze, which keeps students from installing things or chaning settings. My assumption is that one of these drivers is causing the bogus message. Since the computer works fine when booting up from the OS CD, this is the only thing that could be happening. Some other driver is causing the machine to think a USB device is drawing too much power. At least, I think this is what is happening. I'm still working on fixing this problem, but have not been successful yet with removing drivers.

My iphone5 wont charge with usb port but works fine with wall plug... Infact computer. Doesn't recognizes the iphone

Battery not charging with usb port but works fine with wall plug.. So the prob is computer is not detecting the iphone5 . This problem started after upgrading to 6.1.3 version

Try to see what happens on another computer. If it works on another computer, the issue is not at the iPhone.

Iphone 4s no longer recognised by my car stereo (via usb) or by my apple friendly music dock. Any ideas?

My Iphone 4s no longer recognised by my Sony car stereo (via usb) or by my apple friendly music dock. Any ideas?
Had started acting up just prior to IOS 8.0 then seemed ok a few days into using IOS 8.0 but now back to square one.
Have updated to IOS8.0.2 but still nothing.

maybe try cleaning out the port at the bottom of your iphone by blowing it out with compressed air or maybe by using a soft brush. or maybe gently with a toothpick. but nothing metal. perhaps there's dirt or dust in there that's preventing a connection. similarly make sure the connectors on your docks and cables are clean.

My imac is frozen with the following notice: USB over current notice. have tried powered hub, no help. have tried unplug and restart, no help. any suggestions?

Unplug all devices including your mouse and keyboard. Now do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computer's power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
If it starts up normally plug in 1 item at a time. You may have a defective device that is drawing too much current.

"USB Over Current" warnings worse in Leopard than Tiger

Here's a tricky one:
Just bought a 2006 MacBook Pro
2.16GHz, 2GB Ram, 120 GB HD
It came with an openly disclosed problem: a consistent "USB Over Current" error message popping onto screen. (yes, I've read relevant threads and tried resetting PRAM, etc, as did the guy from whom I purchased it). The guy from whom I purchased it was told by a friend in IT that it needs a new USB hub (and that might be correct).
According to the guy and from what I've so far experienced, the USB drives function -- the only problem is the error message.
I used the system disks to perform a hardware test, and also to re-install Tiger (a downgrade from Leopard).
FIRST CLUE -- the Hardware Test
When I perform the "Apple Hardware Test" (version 3A107) the short version shows "no errors" but the extended version gets stuck on "testing memory" (according to the progress bar)
The screen bounces (shimmies) but I believe the error code is:
0x80000009
And:
"ERROR: 0x80000009 requested size: 0xaf
and then another with 0xa4
and another with 0xa4 again
HOWEVER, when the test concludes (in a length of time much greater than its 10-minute estimate), the official word is that there is no hardware problem. (The two RAM modules are the ones specified, and resetting them and removing one did not alleviate the problem).
SECOND CLUE -- Almost no Problem in Tiger
The interesting thing is that with Tiger installed, I got the USB Over Current warning only upon the initial boot. I thought I had just about cured the problem.
THIRD CLUE -- Re-installing Leopard
I took my commercial copy of Leopard and reinstalled. It was interesting that according to what I was seeing onscreen, the installation stalled with 7 minutes to go. But when I rebooted from the start-up disk -- there was Leopard. (Could it have been only partially installed?)
Unfortunately, I didn't see how the computer was running before updating to 10.5.8.
FOURTH CLUE -- Software Updates
The "USB Over Current Warning" now come in cascades of five. And the barrages are frequent. Again, however, they don't seem to do anything except block screen view.
I'm wondering if something in the updates has exacerbated the problem? Here are the updates:
"Pages Update" (2.0.1v2)
"Keynote Update" (3.0.1v2)
"QuickTime" (7.6.9)
"GarageBand Update" (3.0.2)
"iDVD Update" (6.0.4)
"iWeb Update" (1.1.1)
"iTunes" (10.2)
"iMovie HD Combo Update" (6.0.2)
"iPhoto Update" (6.0.4)
"Mac OS X Update Combined" (10.5.8)
Okay, that's the relevant info. I would gladly replace the USB hub, if there's a video that shows how and I know what part to purchase.
Otherwise, what would you do?
Thanks to all who've taken time to analyze this situation.
Kind regards,
Terry D

"USB Over Current Warning"
One thing you have not mentioned is if you have any peripherals connected to the USB when the error message pops up?
I would gladly replace the USB hub, *if there's a video* that shows how and I know what part to purchase.

USB Over Current Notice - Macbook Pro 2006

I had an external hard drive connected to one of my USB ports, and I think the AC Power adapter it was using flipped out. The drive no longer works at all. The port (front left) does not work with any devices (powereded or not) now, but the other two USB ports do (powered devices or not). I figured I'd have to take it in to the shop if I want to get the dead USB port working again. Or, is that something I may be able to fix? Anybody know?
Everytime I power up the computer now, I get this notice: "USB Over Current Notice, A USB device is currently drawing too much power. The hub it is attached to will be deactivated."
It must be referring to the front left port as a hub, right? And since the other ports are still working, am I correct in thinking that each port must be considered an independent hub from the others?
I find it notable that the dead USB port is reporting to continually be "drawing too much power." Maybe the circuitry is just fried so it keeps reporting it??? I have nothing plugged into the port in question.
Does anybody have any helpful ideas how I can remedy this issue besides taking it in to the shop? Anything I can do through software?

time to re-think cost vis-a-vis reliability of these macbook pros
*BINGO !*
Plus,... when you live in the middle of nowhere -like me- and that the nearest Apple authorized reseller doenst give the Apple Care service ? (yes ! I swear, not a lie)
Plus, ... when calling the US complaining the bad Apple service in LatAm, there is no reply ..
Plus, ... no way to contact Apple LatAm ( its a continent, right ? ) Apple LatAm is the only location without phone number in the International Technical Support Numbers ..
I feel VERY VERY alone and frustrated. btw I bought the dearest computer in the world, in order to get the best quality and service
If someone could give me a phone number where I could complain about Apple Care in Argentina
I would be very happy
Thanks for your help/advice Apple people ! http://homepage.mac.com/rdsck/PhotoAlbum24.html

HT4060 iPad will not charge if hooked by USB to pc or plugged into wall. How do I know if the problem is with iPad, cable or power adapter. I have a 12, 10 and 5W adapters no success with any. Only one lightening cable so can't swap cables.

USB over current notice when plugging cinema display

Hello,
I have a 24-inch cinema display connected to my MacBook (aluminium, nov 2008). Both were running well until I suddenly got those warnings "USB over current notice" while working on my computer. I keep getting those warnings when I plug the USB cable of the cinema display to the MacBook. Note that I do not get those warnings when other USB devices (mouse, external HD, iPod) are connected to the Mac. I tried to reset the SMC and PRAM but not to avail. When I plug the USB cable from the cinema display to another Mac I do not get any warning. So, the cable seems OK. Any idea of what's going wrong? Tks

You've probably noticed this has been going on for years. I get it when I plug my iPhone into my Macbook.
Every update that comes gives me hope, but it hasn't been addressed yet.

Mac mini shut down with USB and USB Over Current Notice

I just spent the day dealing with my mini shutting down when I connected my iphone. If I left it connected at restart, I got the infamous USB Over Current Notice. I tried all suggestions and finally used an apple connector instead of the one I had been using. Everything OK again... Other comments? It was very time consuming and frustrating.

Do you have other devices connected to USB ports ?
Try to connect with a powerde hub in between.

USB Over Current Notice - Nothing Connected

Hey all,
so recently i hooked back up my power mac and it worked well for the first couple months.
However, today i was not so lucky. I have a 20 inch apple monitor attached, and it has 2 usb ports. Those ports are almost always plugged in, but when i try to plug them in together, now i get the message 5 times in a row: USB Over Current Notice, A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated.
After playing around with it for over an hour, I've drawn a couple conclusions. If nothing is connected: it will still pop up 5 times in a row. If I have just the keyboard in (and mouse connected to keyboards USB): the message pops up, however the hub (usb on monitor) is not deactivated. If i plug in my music streamer and the keyboard: message pops up and the hub is deactivated.
Finally my troubleshooting.
Resetting the SMU: http://support.apple.com/kb/HT1436
Not sure if this is a late 2004 or late 2005 Power Mac G5, but i did it the 2004 way so far.
Resetting the PRAM: http://support.apple.com/kb/HT1379
Both have not helped the problem, if the problem still exist I will take off the aluminum cover and reset the SMU or PMU or whatever else people suggest within the next couple of days.
Currently on my laptop watching it pop up every 30 seconds between me holding return (closing the 5 windows). ugh

Yes, it's likely the Monitor hub, a common failure point, disconnect the USB to the Monitor & get an AC powered USB2 hub.
