Usb will only work for powered devices
I am having an issue to where my USB ports will only work for devices that have power supplied to them, ie an external hard drive that has a power adapter and not for devices that do not have power supplied to them. I was seeing if anyone could help me resolve this issue?
I have a Macbook Pro 15 inch Late 2011 model w/ the 2.2 Ghz i7 Processor.

This is simply a case of the USB ports not being able to provide enough power. I do not know if there is a way to change this.
This is highly unlikely, the USB specification (to which Apple adhere) requires a constant 1 amp at 5 volts, a peak of 2 amps for a brief period is available. All reputable manufacturers adhere to this spec, it is more likely a fault condition.
To the OP, reset the Pram http://support.apple.com/kb/ht1379
and reset the SMC http://support.apple.com/kb/HT3964
Reboot the machine and try again.
If this brings no relief you should follow Oglethorpes advice and take it to Apple for repair.

Hey.
My USB ports are only working with powered devices ( such as an interactive white board) they are not working wiht a USB modem, it picks up but doenst have the energy to dial out. it also doesnt work with a flash drive.
this is only recent after i updated non vital programs such as printer things.
now the other problem is that i have not updated this too recently but i dont mind losing some info.
ps. i have done all of the restarts such as smc, ram. pram. the only thing i have not done is take out the batt. but thats becuase its really hard to do and there are warnings all over it saying dont remove.
p.p.s i am running snow10.6.8
Please help becuase i need it to help teach some of my stundets and not being able to use a USB or the internet to research is impeeding my planning.
Thanks so much in advance
AndrewOne final detail. it is a 2011 early model. if there is any more details that you want please ask. i am very desperate because i dont want to take it to apple unless i have to.

Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times.
Please help to set it up, thanks in advanceYou need to give more info..
Firstly only works for what.. networking.. backup.. wireless. You need more nouns.. more adjectives... describe what you want and what fails.. then we can figure out why.
Most likely you have bridged it when it should be in router mode..
Most likely you are using Lion or ML which has the airport utility bridge the TC by default.
Change it to working as a router. That might help.
If you press reset button it will default back to router btw.
If you are on Lion.. use a real utility. http://support.apple.com/kb/DL1547 -
USB ports only work when the device is connected at start up
I have a dv5-1110em laptop which I have upgraded to Windows 7.
If i connect a USB device before I start the machine then it works fine as long as I do not unplug it.
If I unplug a device and then need to use it again I have to restart the laptop.
If there are no devices plugged in at start then the ports will not work with any device.
I have installed the new BIOS.
I have uninstalled the USB ports and then re installed them.
I have been searching for an answer to this for months and found nothing that solves my problem.
Any suggestions would be greatly appreciated..
ThanksI'm having the same problem. Installed windows 7 professional over windows 7 home preminu.
Only see USB device if it's plugged in at startup. -
Problem: Why does this only work for powers of 2?
I wrote this program to create a golf league schedule for, ideally, eight players. However I want it to be flexible enough to permit for other denominations, such as 10 or 12. When I run the program it works perfectly for any number that is a power of 2 (2,4,8,16,32,etc...) but it will not work for other even numbers such as 6,10, or 12. If anyone has any insights it would be most helpful.
*(This is my first post on this forum so if anything looks not quite right or if this post isn't worded exactly how it should be then I apologize in advance)*
Here's the three classes.

//for each opponent of player A

count = (a - 1);
flag = 0;
//while still haven't found correct week for this match
while (flag != QUIT)
//if at least one of these players are already scheduled
//for a match this week

System.out.println(schedule[num] + "VS" + schedule[num + 1] +
//incriment num
num++;
}//end for
}//end display
}//end WeekAh, I have discovered the problem. The reason for the infinite loop was because of the resetting of the counter/index after every successful match entry back to (a - 1). This was causing matches to be put into weeks where they didn't belong, which caused the program to infinitely loop because it couldn't find an appropriate week to place it's next match. The only time the count should be reset back to zero is when a new player A is being processed or the last valid array index has been referenced before an out of bounds exception would be thrown. I'm still not entirely sure why this doesn't occur on powers of 2 but theh again I haven't put too much thought into it having solved the initial problem! :)
Anyways thanks for the input all who posted, much appreciated.
Happy programming!!!! -
Siri will only work for US searches
When using Siri in the UK it will only search for companies in the US. Please can any advise me on how to change this although my setting say English (UK)
You can't change it. All you can do is wait for Apple to roll out this functionality to your country. They have stated they will expand the service during 2012, but have not announced any hard dates.

My time capsule will only work with one device at a time
I just purchased the Airport time capsule. I have it set up with my imac, but I also run a macbook air, older macbook, PC laptop, PC desktop, wii, xbox, and 3 iphones off of this device. My issue is that my ISP does not serve more than 1 IP address and with previous routers, the IP address they recognized was only on my router. Now, each time a new device tries to use the internet, my ISP is bypassing time capsule and recognizing the device IP address. It's very frustratitng! How do I set up my Time Capsule so that it's IP address is the only one my ISP recognizes, but all my devices are able to run off of the Time Capsule as the router. (obviously I am not over educated in this area so solutions in simple language are greatly appreciated!) Thanks!
I read the same solution somewhere else in the forum but it does not solve my problem. When I set up the Airport, it sets up in bridge mode by default. When I contacted my ISP they said it needed to be in bridge mode (their rationale is that they only allow 1 IP address). I just switched it to DHCP and NAT and this is what the default settings go to:
After I update it with these settings my internet won't work at all and this is the error message I get:
Any suggestions?

Trusted Sites GPO only works for administrators
I've got a major problem and was hoping somebody could help me. I've got a hundred users or so that connect to an RDS Farm. The RDS farm is made up of several Windows Server 2008 R2 servers. One with IE 10 and the other with IE 8.
The problem that I'm having is if add sites to zone assignment in group policy and add sites to the trusted zone it will only work for users that are administrators. I found a reference to this problem and the issue being IE Enhanced Security, but
Enhanced Security is turned off.
If I'm a normal user with Remote Desktop User rights and I go into IE and check Trusted Sites, there is nothing there. If I login as administrator and check I can see all the trusted sites.
Anyone know how I can fix this?Hi Cyprus,
Please check if you have the computers or users needing the policy are in a group that is specified. Remember that domain users includes all users, domain computers includes all computer, and authenticated users includes both users and computer. By
default, a GPO will be scoped to Authenticated Users.
Also please run gpresult command on non-administrator user to check if it sync to client successfully.
In addition, I suggest you ask Group Policy forum for more professional help:

USB port Working for my Wireless mouse but not working for another Devices like Flash Memory ? Anyone can help me plz?
Hi, is this a question" Post?
or are you just offering an insight into your Mouse Issue?
Generally and at times we all have little idiosyncrasies appearing with the running of our Macs.
I use the same Logitech BT with my MBP. MB & iBook..(not at the same time) Only ever had one issue
and the cure was to completely Delete the mouse from BT -> Repair Permissions & Reboot then Re Install the BT mouse..Ihave just put a new set of batteries in the Logitech (only 2nd set ever)...L -
I have a ipod mini from 2005, it will only work on my charger. I did get a new i pod touch 4, how do i get the music from the old mini to the new touch. I have never put any music on it myself, my ex-husband did it all and has the password. I never new it. I'm sure not about to call him and I don't think he'd give it to me anyway. Please help!!!
I don't think the password will matter, because you can't use anything on the iPod or in iTunes to transfer song files from iPod to computer (except for songs purchased from the iTunes Store). However, there are third-party methods and utilities that can transfer from iPod to computer. If you do a Google search on something like "ipod transfer," you should get some links.
The simple software "lock" used on iPods should not prevent you from off-loading the song files. Once the song files are on your computer, you can add them to your iTunes library. Then, you can do a Restore on the iPod to give it a fresh start and sync it (and the iPod touch) as desired.
NOTE: For songs purchased by you from the iTunes Store, you can also re-download them to your computer at no cost, from the iTunes Store Purchased screen. The link to Purchased is on the iTunes Store Home screen, under QUICK LINKS. -
I purchased Adobe photoshop elements II and Adobe premiere elements II. They are both on one disc. My computer crasded and I had to reload Windows. I only have one serial number and it only works with photoshop II. The same serial number will not work for Premiere. I dont have any other serial numbers. What do I do???
Static_Unit
I am getting a bit concerned about what is happening in your situation. Yesterday you posted your question in at least two different forums, one of them being here in the Premiere Elements Forum.
Don't Have Serial Number for Premiere, Only Photoshop?
Wherever you posted, the reply was to contact Adobe via its Adobe Chat. It is the only one who can sort out this matter for you.
In the thread cited above I offered to help you with the difficulties that you were having visualizing the Adobe Chat in its web page. I was waiting for your follow up on that in the above thread. Instead, I find your same question in a new Adobe Premiere Elements Forum thread this afternoon with no refer the prior threads or prior recommendations given you.
I will also mention again...when you buy the Photoshop Elements and Premiere Elements bundled in one packaging and with installation files for each on the same installation disc, each program has its own serial number. The Photoshop Elements serial number does not work for Premiere Elements and vice versa. The serial numbers are on labels on a box which houses the installation disc envelope(s). So, if you purchased both programs and found the Photoshop Elements serial number, then the Premiere Elements serial number should be in a label right underneath the label with the serial number for Photoshop Elements. I recall writing this in your yesterday's thread on this matter.
The moderator will no doubt be along shortly to close or delete this thread. So, just in case, please bookmark your yesterday's thread cited above so that we can continue this communication which is trying to help you.
Thanks.

My iPod shuffle only worked for a short time. It will not charge and the power light does not come on. Bought it in 2009. Put it back in the box and in my desk. Recently tried to get it to work again but no luck. Anyone else have this problem? Very disappointed with the product although my wifes work perfectly.
Can't say I haven't done the same kind of thing...keep finding things I had every intention of...
If you have the chance stop by an Apple Retail store and talk to them about it...they often work deals for replacement of out of warranty non-working items for prices around half price. Won't hurt to stop by and see what they will do for you. -
My Speakers on my iphone4 will only work when I receive a call or facetime, and are muffled when an alarm goes off. Other than that, I have absolutely no sound from anything- text, music, videos, games, etc. UNLESS I use headphone. My phone will vibrate with text messages, though. When I try to turn up the volume on the side, it doesn't register any bars- the space for the volume boxes is blank. Also, there is no volume bar in my music when I try to turn up the volume. I have tried restarting my phone numerous times, I have also checked and rechecked the switch on the side to no avail. Does anyone have any troubleshooting ideas or know what might cause this?
I tried this and noticed a little green inside the charging port. I panicked thinking it was corrupt, but found out if you lighting moisten the toothbrush with alcohol and gently scrub (with the power off) you can remove the green. I started inspecting one of our charging adapters, which had been giving us trouble, and it was very green inside. Not sure if it can transfer from one to the other?
BUT now I have sound! Thanks for your suggestion, it helped! -
i'm looking for the adobe suite 5.5 and it says it will only work on leopard or snow leopard... but i'm running on lion... anyone know what to do here?
Hi.
I'm guessing that you'r not buying a new edition of the Adobe Suite 5.5.
Apparently Adobe haven't been awake to make sure the 5.5 is 100% compatiable with Lion. However, I do believe it's only a few minor troubles you will experince and Adobe constantly update their software to adjust to Lion.
You should go to Adobe.com and see the list of known issues.
Best regards. -
Battery seems dead. only powers on when charged, but goes off when i unplug it's power cord. And if it was on, i could only use it for about 5 minutes, then it flickers off.
i've tried updating it to ios 7.0, but when it starts to prepare for update it shuts off due to the 5 minute time. I tried that on the device itself, tried with a mac, but it only powers on when charged.
Strange thing, when i go in to recover mode it stays on like.. forever! And if i charge it with a iphone 1A charger it will not pass the apple logo on start up; but if i use the ipad 2A charger it stays on for 5 minutes!!
Please help me, i had this issue foe weeks!
just to tell you people how my ipad got this issue: my sister was playing it at the sofa for an hour or so. then i went and picked it up and tried to power it up, but it just stays black. i charged it, and as i said above, my ipad only works for 5 minutes!
So thanks to whatever who helped me solve this problem!!!!!You followed this exactly?
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
