USB 3.0 Hub for my iMac

Good Day!
Just obtained a Belkin 4 port Hub model : F4U073 purchased through MacStore online.
http://store.apple.com/us/product/HD988ZM/A/belkin-4-port-usb-30-powered-hub?fno de=58
My main purpose was to connect my SuperDrive to it but it doesn't connect.
A message comes up on my iMac monitor indicating that the SuperDrive USB Apple needs to be connected to a Mac's USB port.
3 Questions :
Why is this? Any idea?
Is it worth the purchase or investment if I connect other USB cables to the USB Hub and attach the SuperDrive to the iMac's USB port?
Do I need to use the Power Supply for it to work on my iMac? (It seems to work without it.)
Do I need to use the Power Supply for it to work on a MacBook? (Haven't tried it yet)
Cheers for the New Year!
It will be going down to -20° C or -6° F tonight.
Keeping warm...

SMC Reset:
Shut down the iMac
Unplug the iMac's power cord.
Wait fifteen seconds.
Attach the iMac's power cord.
Wait five seconds, then press the power button to turn on the iMac.
The SuperDrive device must be plugged directly into your iMac.
A SuperDrive device connected to a hub will not have access to extra power above the standard USB specification of the port the device is connecting to
(500 mA for USB 2, and 900 mA for USB 3).
The USB port providing extra power is determined by the SuperDrive device that requires power beyond 500 mA for USB 2, or 900 mA for USB 3. The remaining ports will continue to offer their normal maximum output. Some Apple Macs may offer the ability to operate more than one USB port at 1100 mA at 5 V. On those computers, the second port is enabled when an appropriate device is connected.

USB 2.0 Hubs hooked to iMac G5 can't seem to sustain devices ...

about a month ago I noticed that my iPod and iPhone would occasionally disappear from my Device list in iTunes while plugged in. Both were connected to my computer via USB slots on my NewerTech miniStack v2. I plugged various devices into the USB slots on the Newertech and found that they would fail as well (such as, Turbo.264, iRocks 2.0 USB hub). I then tried plugging the devices directly into the back of my iMac G5 (except the iRocks hub) and they seemed to work fine. I believed I had determined (or so I thought) that the miniStack was failing me (curiously enough, the firewire still worked on the miniStack).
Well I have since unplugged all USB devices from the miniStackand and am using the plain jane iRocks USB 2.0 hub. Unfortunately, as was the case when devices were plugged into the miniStack, devices have started to go missing (unmount, fail, whatever you want to call it). It is important to note that the devices never fail when plugged directly into the back of the iMac G5 (with the exception of the Turbo.264 which has once "failed" when directly plugged into the back of the iMac).
Just last night, when I plugged my iPod 5.5 80gig into the iRocks USB Hub to syn, iTunes told me the file system was corrupt and that I would have to restore the iPod. When I attempted to do so, iTunes gave the the following message: Unable to restore iPod, unknown error occured. Error 1418. I plugged the iPod into the back of the computer and, wouldn't you know, the file system was "no longer corrupt."
Am I looking at a rather large problem with my iMac or have I run across the incredible coincidence of having two USB hubs fail at similar times? Any help would be greatly appreciated.

Miriam,
Thank you for your many responses. I have checked the outlet in so much as I checked other devices (stereos, tvs, etc.) and they seem to work fine. Yes, a power strip is used but again, and maybe I don't understand the difference in how USB uses power and Firewire uses power, but the miniStack uses both USB and Firewire connections. When set strictly to Firewire for the hard drive data transfer, the hard drives never "unmount" or dissapear; this seems to be solely a USB problem.
Now, outside of trying other devices, do you know any other way to test the outlet? I am at a loss but I guess I am grateful that no one has suggested that my iMac is dying lol.
Cheers

What USB 3.0 hub for a new iMac14,2 ?

Will a new iMac14,2 support a USB 3.0 hub?
What models work?
A scanner and a printer will be USB 2.0. An external drive and CD reader/writer will be USB 3.0.
Is there a way to connect these devices to retain USB 3.0 speed on the USB 3.0 devices?

Yes a new iMac will support a USB 3 hub, however like ANY hub connected to an iMac it needs it's own power supply.
USB 3 is backwards compatible to USB 2, no need to worry about that.

Recommended USB 2.0 Hub for iMac G5?

It's strange that Apple doesn't offer something in the online store and I'm not seeing an obvious choice. Any recommendations on a hub, even for a few extra powered USB devices? Seems that most devices want 2.0 power.
Thanks

Hello zipkruse
Welcome to Apple Discussions!
I personally have always purchased and used Belkin Hubs with my Apple/iMac System's.
You can pick-up a 4 or 7 port self-powered _Mac compatible 2.0 hub_ at most local electronic retailer's like BestBuy, Circuit City, Fry's, Staples, Office Max just to name a few.

Yes, I have. I have Astro A50's and the mixamp needs a optical cable. Is there a usb optical adapter that I can plug into the iMac?

HT1151 New iMac, OSX 10.8 and USB 3.0 Hub

I added a usb 3.0 hub to my new iMac and when I boot the vcomputer it only recognizes the device in port 1 of the hub. I need to replug the other devices to get them recognized. Anyone have a solution to this?

You should ideally be using an "externally powered" 3.0 USB hub. Is it? In addition, some brands of USB 3.0 hubs are having trouble with Apple's implementation of the USB 3.0 standard for some reason. You might check the hub's Manufacturer's website for any conflicts reported by them when their product is used with an Apple Mac.

I just bought a new printer for my iMac version 10.7 but I am able to install the software but for some reason I am not able to view the printer under system preferences to add the printer. It is connected with the USB cord!!

Will the iMac support a usb 3.0 hub

I would like to get a 4 + port hub and thought I'd go ahead anf get the USB 3.0 but I'm not sure my MAC can handle it. I have all 2.0 devices now but am thinking about the future. I have the iMAC Quad Core i7.

Apple currently doesn't support USB 3.0 so there is no advantage to getting a USB 3.0 hub. However the hub should work but at 2.0 speeds.

Where can I buy a 3.0 usb hub (2008 version 1 USB 3.0 specification) for my new Mac Mini?

I'd go for the > USB 3.0 4-Port Hub Belkin, mostly because Belkin has never let me down.
Also the > D-Link | DUB-1340 4-Port Superspeed USB 3 Hub, looks like a good choice.

Where do I get the AC to DC Power Adapter for a Linksys "Compact USB 4-Port Hub [USBHUB4C]

I have two Compact USB 4-Port Hubs, Model Number USBHUB4C. These Hubs can be powered, but I cannot find any information on External Power Adapters for these Hubs in any of the documentation or on the Linksys Web Site.
I need to know if Linksys has such Power Adapters available, and if so what the Model Numbers are, and how or where to purchase them.
If I will need a third party Power Adapter, I need to know what the Output Voltage & Current requirements are, and I also need to know the Polarity of the of the two Jack Contacts. [i.e. Is the center pin on the Hub's Jack Positive or Negative?] If possible I'd like to have a recommended Brand and Model Number for the Power Adapter.
Thanks In Advance,
Bruce

Hi, again,
Boy, am I glad I was able to find an answer to my problem in here. I find this very interesting. Here it is, almost 3 years after I made the original post, that I need to find the Power information, for this Device, again, but because of a Computer Crash, I could not get to the original notes, I made about this Forum Entry, so I began the search, again.
I find this very interesting. Here it is, almost 3 years after I made the original post, that I need to find the Power information, for this Device, again, but because of a Computer Crash, I could not get to the original notes, I made about this Forum Entry, so I began the search, again.
I have myriad AC/DC Converters, some of which are Voltage Selectable, but since the Power Specifications aren't on the HUB, or in the PDF Documentation, as is the case with most other Products, I came back to LinkSys/Cisco. As soon as I entered the Model Number of the "Compact USB 4-Port HUBs, Model Number USBHUB4C," for a search, this Forum entry came up on the page, and it appears there haven't been any queries, on any other subject, about this Device, in the interim.
Since the entry has been Viewed 2,484 times, hasn't it dawned on someone that it might be a good idea to carry a Power Product, that is compatible with this HUB, or at least provide a Specific Source, with a Model Number, (for instance, a Radio Shack SKU) so we don't need to hunt for one, over, and over. Why the information was never included in the package with the HUB, beats me. (It should have been on the Device, itself.)
Anyone who knows anything about USB Devices, knows that many of them cannot be powered from the USB Ports on a Computer, especially, on Laptops. Since one of the things mentioned in the Specifications is the fact that you can have "Max. Devices 127 (Daisy-chaining Hubs Together)," it would seem to be obvious that Power Information would be necessary. Since the "Daisy Chain" number is true, it should be obvious, that the "Chain" would require quite a few AC/DC Adapters to power it, adequately.
When this Device was Designed, the requirement for External Power must have been known, or there would never have been a Power Connector built into the Device. I've been in electronics for about 50 years, now, and I know that presently, it's a rarity that the Power Requirements aren't shown on the Device itself, with a Symbol depicting the Polarity of both the Inner, and Outer Conductors. Even Toys have that information shown on them.
I love these HUBs, but LinkSys/Cisco has really dropped the ball on this one. I'm guessing that a lot of people have discovered, that if this 4-Port USB HUB doesn't have External Power, they quickly decided not purchase another one, when they need to "Daisy Chain" them together, for their Network of USB Devices.
When you consider the loss of HUB Sales, coupled with a loss of income from a Power Supply they've never stocked, the numbers could be quite large. That's not even considering the Support time I'm guessing would have been necessary when Customers determined they had a problem, and needed answers. (It's not really a guess, since I talked to several Support People, without getting a satisfactory answer, before I finally came to this Forum, as a last resort.)
I was actually shocked to find that LinkSys/Cisco, didn't sell an AC/DC Power Supply for the HUB, because Power Supplies like that are so commonly required, with the Electronics sold, today. I'd be willing to wager that LinkSys/Cisco does, in fact, carry an AC/DC Power Supply that would be compatible with the "Compact USB 4-Port HUBs, Model Number USBHUB4C," they sell. When something like this happens, I wonder how many other Opportunities like this, have been missed by the people who work for this company.
We've all heard the expression about "Being too close to the Forest, to see the Trees." This may be a good example of it's meaning. At least I was able to find the answer to my Problem, thanks to the fact that the Query I made almost, 3 years ago, which had an answer, was still available to me, thanks to this Forum.
Very Interesting!

Need help on USB hub for mac air 13 inch (2 external hardisk and Iphone)

Hello everyone, I am a new macbook air user, and currently using 2 external hardisk of 1TB and 2TB. I am looking for usb hub that support both of my external hardisk, ethernet and iphone too. The problem is, limited usb hub for mac air and bad review on balkin product, any advice for me?
One more thing, I just moved from window to mac for the first time, and bought Western Digital 2TB external hardisk, the problem is, I can't save any video/audio file that I downloaded from internet in macbook to be transfer/move to this WD 2TB external hardisk, except for back up and time machine. It refuse to except any file that I try to move in to the external hardisk Can anyone help me? compactibility problem?

First, I have not found any of my hubs to have an issue with my MBA. Just make sure that if any peripherals you attached to the hub are adequately powered. Either by having the hub independently powered, or the devices having their own power supply.
The drive problem you have may be due to the file formatting. If this drive is formatted NTFS, then in many cases you can write to it using a network protocol, but OS X can't write to it if attached directly to the computer, e.g. USB, SATA, FireWire. You will neeed to either format the drive as a HFS+ drive, or use software that enables OS X to write directly to t a NTFS formatted drive, such as NTFS-3G. DISCLAIMER: As the information you provide for your circumstances is limited, this is but one suggestion amongst many, that explain your situation.

USB Hub for Mac book air

I recently got a mac book air. And the problem i have is with the USB port. Since there is only one USB port i tried using a 4-port USB hub. Which is working fine on any other Microsoft laptop. ut wen i tried to use it with my mac air it doesnt seem to be working. The funny thing is my mouse is working fine if i connect it through this hub. but my external hard drives are not registering through the hub, but they work if i direct plug it into the port of the mac air. Please help. As i really need the hub for my mac air.

I have two USB hubs without a separate power supply. One is older (USB 1.1) and will drive an external hard drive, the newer hub (2.0) is more compact and will not support an external hard disk drive. I cannot find any listing of the power properties of the hubs themselves, or other hubs for sale, and so do not know which might work better. I suspect a non-powered hub is not ideal for an external hard disk drive.
My solution is to buy a small bluetooth mouse and forget about using a USB hub for a mouse and instead use the port mostly for a USB flash drive.

If the industry agreed with never using external hubs for hard drives they would elimate them from there montherboard designs altogether.
Faulty logic and a wrong premise. Thats like saying "you can get hurt in a car accident with or without a seatbelt, so it doesnt matter"
USB hubs are error-fault multipliers.
To give an analogy you might understand,......your stuff can get lost in the mail on its way to its destination, ..........using a USB hub is like giving your mail to a drunk homeless stranger to carry to the post office first.

Buying a USB hub for the first time

I'm buying a USB hub to connect two printers to a PowerBook G4 and a new MacBook. I've never used a USB hub before, and I'd like to know:
(1) What I need to watch out for (besides how much room it takes up on my crowded desk, which is a major issue), especially whether USB hubs tend to have less power than actual computer ports,
(2) Whether there are any issues with universality because of the Intel chip in the MacBook,
(3) Any particular recommendations? I've been looking at the Belkin 7-port high speed USB and also the Iogear USB 2.0 hub and card reader, but I don't need the card reader and I'm wondering if more is less when you buy a USB hub--i.e., there are more things that can go wrong!
Thanks for any experienced advice out there.

I agree with Ned. Definately get a hub that has its own power supply as it will save you the possible headaches later.
I have used THIS Belkin hub and it works very well and is compact also.
If THIS is the IOGEAR hub/card reader that you are considering - skip it. That is the device that has caused the ONLY kernel panic that I have had in over 2 years of using OS X.
It looks good, but feels rather cheaply made to me and have me KPs to boot. I have a bad overall opinion of that one.
