I had a powered USB hub attached to my computer, w/ a mouse and two printers attached to it. For a while, it seemed to work fine, but then the printers wouldn't work, and I had to connect them directly to the computer. I decided the problem must be with the hub, so I went out to MicroCenter and bought a new powered hub. Again, it seemed to work for a while, but then the printers again wouldn't work. There aren't enough USB ports to run all my peripherals so I have had to disconnect a backup USB hard disk. The hub is now disconnected entirely, and I have to switch connections around. Needless to say, this is a pain.
MacBook Pro 17" 2.33 GHz Intel Core 2 Duo, 4GB Ram, w/ external 22" ViewSonic monitor, running OS 10.5.8
i need a good usb hub that can be powered off the other usb port on my 13in macbook pro cause i have a portable usb hd that when one usb port wont power it can get power off the other and operate but that claims the other port
Find it a bind that the iMac does not have readily accessible USB ports. They are on the back but in my situation to turn the monitor round is a bind. Bought a small USB hub but this does not seem to work with half the devices I want to connect. Anyone any ideas or suggestions to buy a hub that will work with all devices. e.g iPhone etc.
I bought a Belkin powered USB hub and hooked my MacBook Air Superdrive to it and it won't work. I was under the impression it would in a powered USB HUB. Anyone share any experiences with me on this?
I have a 15" PowerBook G4 1.33 Ghz and I discovered that the provided USB ports do not power such devices as portable hard drives or audio interfaces.
So I heard that you need a POWERED USB hub.
I get one, Plug it in. And the PowerBook still doesn't recognize my external hard drive.
My hard drive has two wires on the opposite side from the enclosure that connect to female USB ports. I run an extension cord from one of the males to the other USB port on the PowerBook which is said to work but that also does nothing.
I was thinking that if i bought an external MOBILE hard drive (un-powered) i could take it with me sometimes when i need it in UNI (in Lectures where there is no power source to plug drive in), but also attach it to the mac and since it is un-powered and mobile time machine will work without needing external power.
This is one of the biggest problems i have with my macbook. It has only 2 USB ports... on a regular basis i need atleast 4 USB ports and sometimes 5... What should i do about it ?I used one of those china made USB hubs (with colorful leds) but the speed of access to connected devices becomes really slow. I need a really high speed USB hub.
I have become increasingly frustrated and angry at my MacBook in the last few weeks. Nearly every time I plug in a USB hub, I get a kernel panic. When I send the report to apple, this is what comes up near the bottom of the window:
Sometimes there's a USB HUB written in there. What is going on? I've tried switching from a rather generic hub to a Belkin one, and most recently I just plugged in my aluminum keyboard and immediately got a KP. They've been happening with regularity over the past while, all when I unplug or plugin my USB hub with an iPod touch, keyboard/mouse, USB drive and headset (though recently I've been removing peripherals). I'm about to do an archive and install (assuming my MB works long enough for me to download the combo updater) but want to kill this bug soon.
What kind of USB hub are you using with your Airport extreme? I would like to run my printer and external HD's off of it, but I'm not sure what kind of hub to buy.
I love my iMac but the one thing I hate is that it only has 4 USB ports...
I have 3 USB 2.0 External Drives.... My digital camera, iPhone, iPad, Kodak Zi8, Elgato Eye, and Harmon/Kardon Sound Sticks... and a few other USB devices...
Can anyone suggest a good Powered USB hub? I have this little 4 port laptop USB hub.. right now, but my external keep disconnecting..
Imac, osx Leopard. Was working fine for many months (except for the 27 vertical lines but won't bore you with that), I bought a powered usb2 hub to power a usb hard-drive, when connecting the hub after a few minutes the Internet connection stopped and does so any time I connect the hub, now without the hub being connected the internet stops and starts every few minutes making it impossible to do any work. Other macs in the house are unaffected (s I'm having to write this on a minimac). Has something damaged the imac for good ?
I occasionally have trouble charging my iPhone via my iMac USB ports. I plug in the iPhone, the screen indicators change to show that the phone is charging (green battery indicator and the lightning bolt symbol). However, when I come back to the phone several hours later, the charge indicator hasn't advanced any. For example, if the indicator showed half-full when I plugged it in, it remains half-full.
The iMac does go to sleep a few minutes after I leave it, but sleep has never precluded an iPhone battery charge on my MacBook, and most of the time it works on the iMac.
Is there anything, besides shutting down a computer, that causes a USB port to unpower while the iMac is sleeping? Does it matter whether I am logged in or simply at the login screen?
I recently got a Macbook and have a iPhone and iPod shuffle. The thing is there isn't enough usb ports on the Macbook so I had to get a hub. The hub I got IS self powered and does not require a external power adapter. My concern is that I am withdrawing too much power from my usb port through this hub. It is a 4 port hub and a External HDD ( has own power supply), Optical mouse is connected to it. also I charge my iPhone and shuffle via the same hub.
I am afraid that there is power limit feature and it will fry my computer. I notice if I boot in boot camp to windows. Windows will display a error message telling me, I am not allowed to have this many device drawing this much power. Anyone know if I should be okay as long as OS X doesn't give me a message or should I really consider getting a USB hub with its own power adaptor?
I share a quite common problem. My macbook doesnt boot-up.It does power on and gets into the booting up process but nothing happens... To be more precise, after powering on the MB, the grey display appears and after a while the apple logo and the circle of lines starts to move around.
After that nothing else happens...
I ve tried everything possible... SMC reset, PRAM reset, verifying the disc by booting up either from single user and check it with fsck or with the booting disc and run all the verifying tests and the repair ones... Everything there were just as NORMAL...The OS refuses to open either in normal mode, or at safe mode or even the verbose mode, though it does boot up in single-user mode.
I even took out the HDD and place it in a HDD cover and then plug it as an external device to my other MBP. I run the tests once again but everything seems to be NORMAL again...The only thing that is left to check is whether the boot files have any problem...
What is the most beautiful powered usb hub out there? I'm looking for a hub to go with my mac pro and I have a lot of devices that requires a powered usb connection.
I am the original owner of a Power mac G5 dual 2.0 I purchased this machine in april of 2004 and it has been working nearly non stop ever since. Recently I put it into sleep mode and when I came back it had powered down and would not start up. I assume it's the power supply and I would like to know if there is anyway to tell what type of power supply and model thereof without tearing down the machine.
Information: Powermac G5 Dual 2.0 Mac OS X (10.4.9)
I recently have been having start up problems, when I would hit the power button I would sometimes hear a healthy startup and everything would boot up and then I just get a black screen and you can still tell it has power. I would start and restart untill it would boot. Now the only way the machine will start is if I unplug the moniter cord and plug it back in then it will start.
I have a pc powered iMac and I'm looking for speech to text software. Of course all of the software that sounds really great, like macspeech dictate, needs an intel based machine.
My battery seems to have lost the plot. I can turn my machine on when running off the battery and it fires up as normal. Once it gets to my desktop everything is frozen. The arrow is always stuck in the top left corner and the only thing that works is the power button, but I can't even turn it off because I can't select switch off.
It works fine if I take the battery out and run off the adaptor but kinda defeats the purpose of having a laptop.
A friend and I will be going to Europe in a few weeks. We both have iPhones and I was hoping to charge both of them using my Air so that I do not have to bother with buying extra power converters. I already have the UK and EU plugs for the Air adapter.
I've been trying to find a good, solid powered-USB hub to use with my Macbook Pro. I tried the Belkin 7-port, which had good reviews, but it just stopped working after 2 weeks, and it was never powering self-powered USB hard drives properly (even though it was supposed to).
So I'd like some recommendations for a good USB hub that has sufficient power to use with self-powered USB hard drives and that won't slow down or stop working when i connect too many devices.
To get my Multimedia-Data off my MBP i5 SSD I am looking for a small, 1 2,5" hdd enclosure that is FW-800 powered. I was unable to find anything in the forums nor in the buyers guide about this. Any recommendations or tests? I am looking for something well designed if possible (imho like the LaCie Little Big Disk Quadra, which has two hds (double the power comsumption) and is too big).
I am looking at some OWC external drives to use with time machine on my new iMac. Is it better to go with a bus powered drive or one that has it's own power supply? I like the idea of only having one cable back there to keep with the clean look of the iMac but will go with an AC adapter if need be. Also I have a 1 TB hdd and only using a fraction of it right now. Do I need to go with a 1 TB ext hdd or can I save money with something smaller? Thanks.
