Additional USB port

Many thanks to Ann Bras for recommending a USB Parallel Printer Adaptor to solve my problem of connecting my Laserjet to my IMac. Now I have a follow-on problem. My IMac has 3 USB ports - 1 is used for an HP Photosmart all-in-one, 2 is used for my keyboard and 3 is used for a modem to connect to the web (high speed is unavailable here). Is there a way to connect both printers via the same USB port - something like the old AB boxes used to connect 2 parallel printers in days gone by? Or some other solution?

Hello CarmelJacques
You'll need a USB Hub to expand the number of usb ports.
There are many hubs to choose from 2, 4 and 7 ports are the most common.
There are unpowered 2 port hubs or splitters and powered 4, 7 or more port hubs.
I suggest a 4 port powered hub as your best option for two good reasons.
1) Powered hubs supply power for the devices plugged into your iMac!
2) 4 ports will give you 2 spair ports for added devices (Camera, iPod or usb External HD)
You will find them online Google (usb hubs) or at your local electronic's store. Be sure it's Mac OS X campatible!!!
Here is a Belkin 4 port powered hub that works for me in the link below.

Additional USB ports...

Hi,
Very happy with my new Mac Mini (first ever Mac) but find I'm really needing more USB ports...
I dare say this will not be an issue once I've acquired a magic mouse and Apple Keyboard, but just now I am lacking in that area...
Is there a recommended solution, or is it just a trip to PC World to pick up a cheap hub...???
Dougie.

USB 3.0 Hub attached to a Mac Mini does not work

I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

Add more usb ports

I have the microsoft arc mouse and keyboard and each of them have seperate transrecievers. The macbook air only has two ports. If I bought a usb hub would this enable me to plug the transrecievers into the hub so I would have 1 usb port free? Or is there no way to do this?
Thanks.
Im considering returning them and getting logtech's unifying transreciever, but they have no small keyboards that are compatible with it:(

RF/Bluetooth dongles and small flash drives are very low power, and provided the USB hub itself isn't a power hog, you should have no problem using an unpowered USB hub to connect those two transeivers to the Air.
I bought one of these a couple of years ago. It's ideal for a MBA user, as it is small enough to fit right in with the portability of the Air. And I have never had a problem with two transceiver dongles or two flash drives.

Sadly though, it appears that Griffin stopped making them when the Air added an additional USB port on the 2010 edition.
But there are still a myriad of miniature 2 and 4 port unpowered/self powered hubs that should work just fine for you.

Airport extreme working with external hard drive via USB port adaptor :)

Hi Everyone. I hope this post will be helpful because I have been very frustrated with apple and their customer support and I figured this out on my own by reading all of the discussions and playing with my settings but it took me a while...
I recently for school bought all apple products and I have non-mac products as well. I bought the airport extreme believing I could hook up all of my computers through it and share the printers and my mybook external hard drive with my husbands desktop and the other lap tops. Unfortunately this was not as easy as advertised...
I was not able to successfully have both computers stay connected to the printers so I have to have mine for my laptop connected via the airport extreme and my husband has his desktop connected to a different printer via a ethernet cable. It would work at set up and then a few hours later not print anymore and reinstalling the drivers just confused it... if anyone knows a solution for this please let me know. It worked wirelessly for me but not for him.
As far as the external drive for the airport extreme goes I went and bought an additional USB port hub so I could access my printer wirelessly and my external hard drive as well for time machine back ups.
I set up my external hard drive so that it will save files from both a mac and a non-mac computer and we can both access it (not sure if that matters in the solution or problem for others); however, the desktop (non-mac) was able to by clicking and dragging files to it assess the hard drive and utilize it and my macbook was not able to because the airport extreme showed the drive under disks but when I tried to access it through time machine it was not there. I played with this for a long time and finally figured it out.
I believe I went under finder, then chose go from the menu bar, then chose connect to server and the default for it is afp://10.0.1.1.. You enter this in under server address and you may be prompted to give your password. The password was tricky as well because it showed my computers user name and I thought it would want that password but instead it wanted the password to log into my internet or my airport extreme's password. Once I put this in I was able to open my time machine preferences, finally choose the mybook external hard drive that was now showing up, choose it and my computer is currently doing a back up as I type without the error message of failed, unable to locate volume, or any others.
Hope this posting was helpful and not to confusing and feel free to message me if you need clarification and think this may solve your problem as well. GOOD LUCK!

Seems to me you should have done your homework setting up your network and not assuming that any third party device you choose to use would work without problems.

Additional USB/FireWire ports

Is there anything I can use to get additional USB and/or FireWire ports? (Such as a splitter (of sorts) or like an electrical strip (WHere you plug it into 1 outlet and gain x # of outlets)?
Thanks

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 ?

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

I've upgraded to OS 10.8.2 and my Bowers and Wilkins MM-1 Speakers were working fine until today, and now they won't play any sound at all, even though iTunes shows the audio is playing. I've tried both the headphone jack and the USB port. Please help!

Thank you,

Michael,
Thanks. I haven't mixed down the audio or checked the number of tracks in Prefs. Good points.
As far as a mixdown goes, I'll definitely give it a try, though I wonder whether or not the tracks will be recognized during mix down recording - given that you can't hear either of those segments in playback. Just have to try.
Re the preferred number of allowed tracks - I'll go check as soon as I send this off, but I'm not sure that applies in this case, since the two Channels containing the segments that are pinked out are not in additional tracks. I should have mentioned that other audio clips and segments on the same Channels in the SAME tracks ARE heard in playback. As are two additional track in the 2nd Sequence. It's only when the two sequences are joined that the pink tinted segments can't be heard. Within the sequence the same audio cuts playback as they should. Thanks again &
Best regards,
David

Itunes Freezes during Sync on 3G & 3GS with Vista 64 & 7-64 all USB ports

To start. I originally had an iPhone 3G over a year ago on this desktop running Windows Vista 64Bit. My phone was able to sync with the PC for about a month and stopped being able to sync. I received many error numbers and put support tickets in with no avail. I then upgraded to an iPhone 3GS. Still under Windows Vista 64Bit and could not Sync my phone. It consistantly froze during the sync process. I tried all USB ports on my PC. People said to try restoring your iPhone and iTunes. I tried that and then got stuck on my restore. I had a broken phone until I was able to sync with my laptop.
I now have the same desktop Acer AM3641-EQ8200A but I am running Windows 7 Ultimate 64bit. I have always had the latest iTunes version, and tried 32 bit and 64 bit versions of iTunes. I still cannot successfully sync my iPhone. If it sits there long enough it will freeze up, start to freeze my computer etc. I decided to try again last night after I got a new USB cord and had the same issue.
In addition, my girlfriends iPod will not sync to the desktop either.
I have been stuck doing syncs on my Netbook for over a year now. Optimization of 3,000+ photos is horrific on it, but it works.
People say to get an external USB that is self powered. Why should I have to do this and chance frying my PC?
The deal is this, the phones won't sync with the desktop but will sync with my netbook also running windows 7 ultimate. All USB drivers are up to date on both.
I have tried Reformatting and Installing Windows. Reinstalling itunes. Updating all drivers. Tried different versions of iTunes. I first called Apple Retail, they had no answer. I wrote apple a lengthy letter with all the Error codes, they said they would call me even though my warranty over the phone support was expired. Never got a call back after they heard my problem.
What can I do to rectify this? I am not the only one out there.

UPDATE:
After putting a USB 2 card in my mac, all worked properly. The problem seems to be using USB 1.1.
This is really tragic because:
+ many Macs don't have USB 2,
+ it is very difficult to find out out if USB 2 exists on your computer (why are no USB 1 or 2 details spelled out in system profiler ?),
+ there are no warnings as to the sort of issues that would be coming up with USB 1.1 (yes I know the specs clearly says USB 2, but it looks like it was working at first),
+ there are no spelled warning by the system (after all, the iTune, iPod combination could detect easily that the incorrect USB standard is being used and warn the user),
+ there does not seem to be specific advantages to use USB 2 (like speed) as the syncing peaked at 6MB/s, a speed achievable with USB 1.1
Come on Apple you can do better than this !

USB Ports No Power

I have a HP Pavillion dv4-1435dx. I changed the processor on it, ever since my USB ports have no power. I went into device manager and uninstalled the drivers and took out the battery on the laptop and started it back up and they still dont work. Can someone help me out please or direct me where to find help?

The issue can be caused by the USB controllers. Please follow the steps below to reload USB controllers.
1. Click "Start", type in Device Manager the Search bar and press "Enter". Click Continue if necessary.
2. In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the "Host Controller", click "Uninstall" and click "OK".
3. Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and Windows will reinstall all USB controllers automatically.
If the issue persists, I suggest that you download the latest chipset driver and BIOS from the following website, and then install then in Windows 7 RC.

HT204392 Just Made the switch from PC to a 27" iMac. USB Ports full !

After adding my iPhone charger, my Printer, a superdrive and the Bose Companion 5 speakers, my USB ports are full! Any good HUBs out there or other connection solutions? Not sure what the Thunderbolt connections are for, except additional monitors? Is it possible to adapt those to USB 3.0?
I've been considering the Logitech Keyboard to pick up the numeric keypad but it requires a USB port as does my DSLR. Right now I remove the SD card from the camera, but firmware updates are a pain since I have to reach around the back of the iMac and choose one of the cables to temporarily remove. Not sure what others are doing to silve this problem and I know hubs can be buggy...

There are also USB hubs that will connect to the Thunderbolt port.
This one Thunderbolt™ Express Dock for Mac from Belkin also has a FireWire Port. There are less expensive ones out there search for thunderbolt usb hub

I just bought a new ipod touch and when i plug it into my Mac usb port nothing is happening I can get the computer to sync other ipod in the same port

Try:
iPhone, iPad, iPod touch: Device not recognized in iTunes for Mac OS X
Do not omit the Additional Information paragraph.
Is the iPod that connects an iPod touch? If not that does not mean anything since iOS devices like iPod touch, iPhone and iPad use different drivers than other iPods.
