Hello good evening, I have a MacBook Pro and my problem is that one of the USB ports and the device does not detect this and inactive but can not find how to reactivate.
Help me please! greetings thanks!

Do you have the Firefox new tab page but the actual sites are missing, or do you have some other page?
If you have some different page, try the quick fix in Fred McD's reply.
If the sites are missing, did you use the Reset feature? That will clear the storage associated with the new tab page. I'm not sure it's possible to recover from that; you probably need to rebuild your page from scratch as you browse.
For possible future reference, here is how to access the hidden setting for the page to display on new tabs:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste '''newtab''' and pause while the list is filtered
(3) Double-click the '''browser.newtab.url''' preference and enter your preferred page:
* ''Page thumbnails (default)'' => about:newtab
* ''Blank tab'' => about:blank
* ''Built-in Firefox home page'' => about:home
* ''Any other page'' => full URL to the page
Press Ctrl+t to open a new tab and verify that it worked. Fixed?
Some gotchas:
''If Firefox won't let you edit this setting:'' you may have something called SearchProtect on your system.
''If Firefox lets you save your change but ignores it:'' one of your extensions may be overriding it. You can review, disable, and/or remove extensions on the add-ons page:
"3-bar" menu button (or Tools menu) > Add-ons > ''in the left column click'' Extensions
''If the change works during your session, but at the next startup is back to an unwanted page:'' you might have a user.js file in your personal Firefox settings folder (your Firefox profile folder). This article describes how to track down and remove the file: [[How to fix preferences that won't save]].
Any luck?

I have an optical mouse that came with my Mac Pro plugged into the USB port on the keyboard. After a year of working normally, the trackball all of a sudden stopped scrolling down. It scrolls up just fine, but not down. Any thoughts?

I have an optical mouse that came with my Mac Pro, the only thing plugged into the USB port on the keyboard. After a year of working normally, the trackball all of a sudden stopped scrolling down. It scrolls up just fine, but not down. Any thoughts?

Well
I tried all of the suggestions, sort of. I did not have alcohol wipes, but I did take alcohol and pour some ona white paper towel and then rolled the mouse touch ball aroound and that finally cleared up the problem. Just inverting it on paper did not do the reick, it needed some help with the alcohol. Of course the probelm is the debris that gets inside and it really needs to come out.
This is a huge problem for RIM devices users too.

- Try restoring the iPod, first from backup and then try to factory settings/new iPod to rule out a software problem.
- Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and broken or cracked plastic.
- Could you have damaged something when you took the iPod apart and replaced the Home button?

One of the USB ports on MacBook Pro does not work.

Hi,
I purchased a MacBook Pro in Jan '11. Both the USB ports on the laptop were working fine. Recently, I have noticed, any external device connected to the USB port, towards the battery side does not recognize the connection.
Any solutions ?. Is this defect covered under warranty ?.
Regards
Anil Madan

Anil,
Try resetting the SMC.
SMC RESET
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.

Is it possible to scan with an Multifunction Printer Epson Stylus 8300 series trough the USB port of the Airport Extreme?

I have an Epson Stylus 8300 series, and plugged in the USB output of my Airport Extreme, with that I can print without problems from any PC connected to my WiFi network, but can not in any way to scan photos and documents over the network , and every time I need to do this activity, I have to connect my printer directly to the computer. Could someone help me with this problem?

Sorry, but Epson and other manufacturers have not provided full featured drivers that would allow advanced features like copy, scan and maintenance to work when their devices are connected to the USB port on the AirPorts.
Only the print function will work when the All-in-One device is connected to the USB port on the AirPorts.
If you can connect the All-in-One using wireless only or Ethernet, most manufacturers have provided full functionality with these types of network connections.

Can't use my HP Deskjet F4580 Wireless Printer with the AirPort Extreme Base. The printer is NOT connected at the USB port of the AirPort Extreme, and is placed in another room. It worked just fine with my previous router (Linksys WRT54G). Help me!

Hey Guys!
I just got my AirPort Extreme Base, but I can't use my HP Deskjet F4580 wireless printer with it.
The printer is not connected to the AirPort Extreme's USB port. It is placed in another room, and I'd like to use it (the printer) wirelessly (not connected to the USB port os the AirPort Extreme), as I used to. There is no place for the printer close the AirPort Extreme. It worked just fine with my previous wireless router (Linksys WRT54G). I'm very disappointed with the AirPort Extreme Base Station because of that!...
Can you help me? Please?!
Thanks Folks!

This must be a tough one, no suggestions at all.

Can anyone explain when the USB port on the Express is really needed?

Back with another question!
My Airport Express is used only for my Canon printer (MP980), nothing else. I know, with hooking up my new Mac Mini, I'll get new drivers from Apple and will need to install some of the updated software from Canon... from what I've read, I won't try to use the disc that originally came with the printer.
Since I'll join my Airport network for printing after my older Mini is disconnected, when is there a need to use the USB port on the Express? I've read that it's used for connecting multiple computers to the network. But, I'm having some confusion with this. With my network up and running, I assume I would be able to use my old Mini and the new Mini on the same network, if I decided to unplug one and use the other one for a short time, since my network settings won't change. (I have but one monitor!). Is a USB connection to the printer only required if multiple computers are shared simultaneously with the printer via Airport Express?? I never really understood this completely. All I expect to do for a few months is occasionally unplug one Mini for the other as I save some files onto disc, etc.
Did I make sense?

you can hook up a printer (or a Keyspan remote to control iTunes). one aspect may be location. what if you want the printer in a different room or on a different floor in the house ?

yes, you can also share a printer connected to your mini with other client machines.
btw, you could use the +screen sharing+ feature to access and manage the screenless mini.

no, all machines on your network could use a printer connected to either of your mini's or connected to the AX.

Can a USB Keyboard/Barcode reader be used with the USB port on the CRio

Is it possible to use a USB Keyboard or Barcode reader with the USB port on the CRio, I know you can use this port with a USB memory device, but what about other devices?
I have a project that requires that all hardware elements be connected to the controller and use the HMI purely for display,
anybody any ideas??

Hi kmoyna,
The standard CompactRIO range's USB host ports are not suitable for standard USB devices like keyboards or barcode readers - they are intended only for use of mass storage devices. From your description, it seems your project's requirements would be best met by the newer models, cRIO-9081 or cRIO-9082. These two units have Windows Embedded Standard 7 (WES7) and allow the direct connection of a monitor and standard USB devices. We now also have similar stand-alone CompactDAQ models running WES7 - cDAQ 9139.
I would recommend calling into your local branch to discuss your project further with one of our engineers. If you're in the UK, it's 01635 523 545 - or view contact details for other branches.

The USB port on the new keyboards

Hi,
I'd just like to have your opinion about the placement of the USB port on the new mac keyboard. I think it is a pity that they are so far away under the keyboard. It makes them difficult to access. Besides, what if your USB device is a bit large. You cannot plug it in for pure physical reasons.
Another mistake from apple? What do you think?

But I could counter that my wife likes the way the USB port is recessed because her thumb drive fits perfectly doesn't protrude from the keyboard unlike with other keyboards. Since getting this keyboard she hasn't knocked her thumb drive lose and hasn't set her drink on it. And let's be serious - how difficult is it to lift up the keyboard to plug in a device? How onerous is it to buy a little extender if you do find lifting the keyboard such a time wasting task? Okay, I'll tone down the sarcasm
Thanks. Point is, it adds an extra step. Macs should be more user friendly. No, it is not hard to lift the keyboard, but why should we have to when before you just saw the port and attached away?
If you want to complain about design decisions, let's ask a few questions that might be more serious? Why is the power button hidden on back in stead of conveniently in front? Why isn't there at least a visual cue telling is where to insert a disc? Why isn't there a way to vertically adjust the display? Why are all the ports on back? Wouldn't it be convenient to have at least one USB port in front? Where is the little LED that pulses to let us know the computer is asleep?
Well, this thread wasn't directed at the new iMac's other design quirks, but since you bring it up.
1) Yes, that power button in the back left me scratching my head. I'm used to it now, but it is another good example of form over function.
2) I insterted a disc backwards the first time, silly me.
3) It is so big, why do you need to vertically adjust it?
4) Ports on the front would make things easier, yet. And you wouldn't have to lift the keyboard But it would interfere with the clean appearance.
5) I miss that LED too....

Will the USB port from the Time Capsule power an external hard drive?

I am interested in purchasing an external hard drive (Iomega 1TB Helium Portable or G-Technology 750GB G-DRIVE mobile)
to connect to my time capsule, expanding my wireless storage, but I want to know if the Time Capsule has a powered USB port or does the drive I purchase need to have its own power source? Also, Is there any compromise to using a drive that is USB powered, vs one that requires a power source?
Thanks!

Even if the hard drive that you choose has its own power supply, you usually need to use a powered USB hub with the Time Capsule.
Reason....the USB port on the Time Capsule is under powered. You should not really rely on this port to power anything except a single printer.

Why does my nook open iphoto when i plug it in the usb port on the back of my imac running 10.6.8

I have downloaded Adobe Digital Editions and downloaded Overdrive from the public library. When I plug the Nook eReader in the USB port in the back of the iMac, iPhoto opens immediately. I know this is not a forum for Nook eReaders, but I have to start somewhere and figured since iPhoto is opening automatically, maybe someone can give me a clue.
thank you,

Most likely, because your Mac and iPhoto think that you have connected a camera or mass storage device that has images on it.
Not sure where to go from there, but I would start by looking at the setting in both iPhoto Preferences and Image Capture if I wanted iPhoto to ignore that device.

The USB port in the back of the Hub

Can I plug in a portable hard drive into the USB port in the back of the BT Hub, so the files on the drive will be available to all pc's on my home network?
Solved!
Go to Solution.

In theory yes depending on which homehub you have. Some have found it works without problem others have found it does not get recognised. Do a search of the forum if you have problems and you'll find plenty of advice.

Is the USB Port in the front of G5, USB 1.1

Hi All,
Can anyone confirm this? Is the USB port in the front of the G5 only USB 1.1? I hooked up a USB hard drive to the front port and the transfer speeds were super slow. I checked the system profiler and it said the max speed was 12Mbs. Then I hooked that same USB hard drive to the back USB port and the speeds increased significantly. I checked the system profiler and it said the max speed was 480Mbs. I thought all the USB ports on the G5 were USB 2.0, or is my front USB port dying ? Please confirm. Thanks.

The USB ports on the G5 itself are USB 2.0. Those on the keyboard which came with it are USB 1.1.

I have an iMac and also a MacBook. All of a sudden my iMac does not recognise my Canon 500D camera even though I have downloaded 1000s of photographs from it via the USB port. The MacBook recognises the camera immediately. Can anyone help?

Thank you for your reply. I know I can use a card reader however I don't see why I should when importing directly from my camera has worked reliably for years. The process I use is simply connecting the digital output from my camera to the USB port on the iMac, which has previously automatically opened iPhoto ready for the import. Now all of a sudden my iMac does not recognise the camera. However if I connect in the same way to my MacBook then iPhoto opens automatically on the MacBook, recognises the camera and is ready for importing. So whilst I know I can use a reader, or my MacBook I want to use my iMac in the same way that I have for years. I can only assume that the settings on the iMac may have changed, but I cannot verify this.

How do I use my ipod in the car without it constantly charging? I have to use a docking cable into the USB port because the 3.5 mm to 3.5mm jack I bought doesn't work on the ipod.

How do I use my ipod in the car without it constantly charging? I have to use a docking cable into the USB port because the 3.5mm to 3.5mm jack I bought doesn't work with the ipod (although it does work with an MP3 player). My ipod is a 5th generation 80GB classic.

I know this is old - but did you ever get this working. Thinking of getting a 780 ti card and I have an older mac with the mini-displayport too.

My problem is that one of the USB ports and the device does not detect this and inactive but can not find how to reactivate.Help me please! greetings thanks!
