Broken USB and USB Hubs

Hey guys, one of my USBs randomly stopped working today.
Ive invested in one of these : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170447166512
Is there any risk of this burning out the last remaining USB? Keep in mind i hope to input two external drives, 2 USB Pens, 1 Keyboard and a printer.
Without any USBs i might as-well throw my notebook in the bin lol, is iots costly to get USBs fixed by apple?

That should enable you to run all your devices off your one working USB port, but you'll certainly have to use the hub's AC adapter to provide power to those that need it.
Before giving up on your other USB port, reset your SMC and see whether that brings it back to life:

USB and Firewire Hubs

Hi All and Happy New Year,
I am trying to connect all my peripherals to my G4 iMac.
I am uncertain which devices will need USB2.0 and those that can get by with USB 1.1.
I have questions that hopefully can be answered here. I have the following devices.
2 Epson Printers R200 and R2400
2 Scanners Minolta/Dimage 5400 film scanner and an Epson Perfect 1870 flatbed
2 External Hard drives Maxtor FW 300GB One-Touch and Lacie FW 250GB
This is what I am trying to use to connect everything.
Belkin 4 port 2.0 USB Hub
D-Link 4 port 1.1 USB Hub
ADS Dual Link 4 2.0 USB and 3 Firewire 400
Should I daisy chain the hard drives?
Can I plug the D-Link 4 port 1.1 USB Hub un-powered into the either of the other hubs?
This hub would be used for low power devices like card readers and whatever other ones that are suggested here.
Can I plug the Belkin 4 port 2.0 USB Hub un-powered into the powered ADS hub?
Which devices need to be connected to the native USB/FW ports on the iMac?
Sorry for so many questions but I went to 2 different Apple Stores and got completely different answers.
I appreciate the help and direction.
Thanks COVRC

I would configure as follows.
USB2.0 (Port 1) - (powered) Belkin USB2.0 Hub - (Port 1) R200, (Port 2) R2400, (Port 3) Epson Scanner, (Port 4) Card reader,
USB2.0 (Port 2) - Apple Keyboard and Mouse
USB2.0 (Port 3) - Minolta Scanner
Firewire (Port 1) - Lacie FW 250GB
Firewire (Port 2) - Maxtor FW 300GB
I feel like I'm missing the point as you don't seem to list enough devices to use more than one hub.

Any recommendations on a good USB and FireWire Hub?

Just bought a MacBook Pro and I'm about to start experimenting with Final Cut Express. With ports needed for usb powered speakers, a mic, a mouse, a usb flash reader (for photos)... and firewire ports needed to upload video and to connect an external drive, I'm thinking I need a hub.
Belkin has one- http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore?productLearnMore=TE2 88LL/A
But apparently, some come with- as if we haven't heard enough of it- a high-pitched whine.
Anyone have any experience with the ones from-

The problem with a Firewire hub is you are still limited to one Firewire bus. Fortunately Express/34 cards exist with Firewire to add a Firewire bus:
http://discussions.apple.com/message.jspa?messageID=2119050
You may want to consider getting a 160 GB hard drive for your MacBook to have more storage for video and partitoning that drive to use part for just temporary scratch storage space which can be erased with Disk Utility.
As for USB hubs, always get ones that have their own external power supply from the computer, and don't use the bus power unless the devices you are hooking up have their own power. I have the MacAlly hub, yet even this great hub can't hook up an external Firewire hard disk and an EyeTV simultaneously.

Mac mini shut down with USB and USB Over Current Notice

I just spent the day dealing with my mini shutting down when I connected my iphone. If I left it connected at restart, I got the infamous USB Over Current Notice. I tried all suggestions and finally used an apple connector instead of the one I had been using. Everything OK again... Other comments? It was very time consuming and frustrating.

Do you have other devices connected to USB ports ?
Try to connect with a powerde hub in between.

Is it possible to use USB webcam + USB mic simultaneously?

I would like to use a USB mic (Blue Snowball USB) and USB webcam (Ligoitch Quickcam) together simultaneously, because I understand the one is good sound and the other is good video for live internet broadcasting of music.
can anyone tell me if this should be possible? I'd hate to buy them and find it doesn't work... THANKS!
I'm using Macbook 2.2 GHz Intel Core 2 Duo OSX 10.5.8

No reason why not.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

I have a 2006 15" Macbook Pro with a broken Superdrive and my external USB one just quit working

Why can my LG Portable Super Multi Drive (GP08NU6B) burn discs, but not read them? Right after I burn a DVD successfully, I stick it back in the drive and it says "The disk you have inserted is not readable by this computer" I have a 2006 15" Macbook Pro with a broken Superdrive, and this external disk drive is the only optical drive that worked via USB. This external drive was bought in 2010 and worked fine up until a month ago. This is supposed to be a Plug and Play device, and LG assures me the drivers are already included in Mac OSX, yet it seems somehow my Macbook lost the drivers and it won't let me watch DVDs now or recognize any discs at all!
How can I find and somehow reinstall the firmware for this optical drive?

Sounds more like a hardware issue to me.

Mac Mini and USB 2.0 hubs (hubs stop working within a month)

I have an aluminum Mini running OSX 10.6.6 (Snow Leopard). With only 4 USB ports, I have need of a USB hub to accommodate my external drives and other peripherals: keyboard/mouse, camera and iPhone have to use the existing ports in the Mini (difficult access to ports due to space limitations), leaving one port for up to 4 external drives (older drives 40-60gb used for backup and extra storage).
I have problems using powered USB 2.0 hubs with this computer; I have 'burned out' 2 hubs since buying the Mini in February. They just flat out stop working, though they still show power (the power indicator light on the hubs); no peripheral is recognized when plugged into the hub (which worked fine for about a month). I can unplug the 'must use Mini ports' (camera, iPhone, charger, etc) and the peripheral drives are recognized and work normally when plugged directly into the Mini ports.
One hub was a Belkin 4-port hub (about 1 year old) and the other was a GE 3-port hub with several flash card readers (19-in-1 card reader), also about a year old. Is there any reasonable explanation why powered hubs would suddenly stop working, related to use with the Mac Mini 2010 aluminum version?
I had worse problems with the USB ports in an old (~2006) Mac Mini (out of warranty), where the USB ports in the Mini stopped working, which is partly why I bought the new mini. In light of this tidbit, (be honest, please) are there known issues with Mac Minis and USB?

Each of the external drives has its own power supply; I generally only use one drive at any one time, but on rare occasions I have powered up more than one to confirm or transfer files. I don't leave any of those drives on when not in use, and when everything is working I properly eject/unmount them before turning them off.
There have been times when I powered up a drive connected to a powered hub and both the hub and the drive indicated activity but the drive didn't mount. On those occasions the drives sometimes would not appear in Disk Utility, and other times would appear, but would not be "mountable". I didn't know what the best way to deal with that was, so I would just turn the drive off, hoping the lack of mounting on the desktop meant no real drive activity was occurring and I wouldn't risk data loss or drive damage. So far all the drives seem to work fine when plugged directly into the back of the mini.
The main external hard drive I was using when the Belkin hub failed (iomega 40g) is USB 2.0 only (no firewire). I have another drive that is only firewire (la cie 60g)... so it wasn't a factor. Two other external drives are ACOM, one 40g one 120g, and then there's my old iMac G5 disk (display fizzled and everything but the disk recycled through Apple's recycling program) which is mounted in an external enclosure and is part of the USB contingent, but is not being used for anything but backup (all three both USB 2 and FW400 capable). (I know, too many toys... but why throw them out?)
The USB hubs both had their own power supplies, too, and I never used them without power (though I tried it as part of troubleshooting, before reading the Apple article on USB and power requirements). Other USB devices that only work when plugged into the mac directly are my Epson Stylus CX4800 all-in-one, and my Radio Shark.
So, whaddya think? Should I risk buying another powered USB hub or just live with plugging in peripherals to one available USB port (through a short USB 2.0 extension) and only use one at a time? That would be a bit of a pain, but if there are no issues you've heard of with Mac USB ports (several unanswered questions in the Mini Support forums here involving USB and peripherals, I noticed), what else would explain the seemingly short lives of USB hubs?
Oh, here's something I just remembered: the last time the Belkin hub was working (last night), I had my Radtech BT mouse charger cable plugged in (not charging, mouse not attached) along with two of the external hard drives, and my Fuji camera USB cable. I got an error message onscreen (on the Mini) that a drive had been improperly ejected (or put away?), yet the hard drive in question was still mounted on the desktop. I looked at the hub, and the loose ends of the charger and the camera USB cable were touching. Could that have caused the error (and maybe the hub to fail)? (Edit: the camera cable I think was plugged into the mini's one available port; 3 external drives and the mouse charger were plugged into the hub, _but only one drive powered up and in use (3rd edit)_. The camera end of its USB cable contacted the mini-plug end of the mouse charger... could that have short-circuited the hub? +That wouldn't explain the failure of the GE hub a couple weeks before... but I don't know if any of this is connected, so to speak--2nd edit.+)

Airport Extreme and USB/Firewire Combo Hub

This has probably been covered before and I didn't find it. So I apologize...
I bought the new Airport Extreme and a firewire/usb combo hub so that I could connect my external HDs (3 are firewire and 1 is USB) - the USB is the only one that is working....
Any Ideas? (Besides putting the Firewire back on the desk top and sucking it up!)
Thanks,
Tim

I have a related question. I want to buy a triple interface drive (ethernet, USB, Firewire). The plan is to connect the drive an ethernet port on an Airport Extreme. The question is - can I later 'daisychain' on an additional firewire drive?
So the first drive would be connected via ethernet and the second connected to the first via firewire.
Based on Niel's post, I am guessing this won't work. Comments?
Also, are there certain brands that are known to play particularly nicely with Leopard when hooked up as ethernet network drives?

IPhone and USB hub ....

Hi,
Is there a reason why my iPhone does not show up when connected to my USB 2.0 hub ??? If connected to my iMac it shows up ...
Thanks in advance.

Apple usually prevents problems that simple. My computer's 3 USP ports are already crowded ... Plugging my iPhone to my iMac is a plug/unplug situation.
So plug your other devices into the hub and reserve one dedicated USB port for the iPhone.
I would have also thought Apple would have implemented a feature that exists already in most of cell phones, a wireless connection to sync with the computer. No wireless and no USB hub connection.
The iPhone is not most cell phones. It is a unique piece with unique features. If it did everything that other cells did the same way there would be no need for it.
If I add to that the absence of a search feature in iCal and Address Book, the fact that they are no notes already implemeted, I would say they are letting go features bit by bit. Design is good and can get iPhone sold, but we usually think of Apple more like a genial feature driven architect.
http://www.apple.com/feedback/iphone.htm.
Narrowing us to use only one cellular company to get a share of our ATT's (or other cell phone companies) monthly cell fees is the biggest insult to the Apple community. In business we call this a «kick back» and it is normally badly perceived. You sell your product a decent price and with honest and upfront conditions and customers will respect and be loyal. I really don't appreciate this move from Apple and me and my family are loyal users since 1984. Considering asiatic markets are potential buyers and can give Apple big profits, Apple can afford to offer a unlocked iPhone to the world.
Its not uncommon for a cell to be locked to a carrier upon initial release. In addition to this, there are a few features on the iPhone (Visual Voicemail) that required the carriers to upgrade their current systems. This could not have been offered with an unlocked release.

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.

Surround 5.1 X-Fi (regular and pro) on usb 2.0 hub?

Hi, is there any kind of negati've consequences with using the x-fi 5. old or pro on a usb 2.0 hub? Will I experience any kind of noticeable delay or reduced sound quality? I'm using a Belkin one...
I have a dilemma where I need exactly one more usb slot for my laptop.. So if there actually are issues with this, perhaps someone could suggest a high quality usb 2.0 hub I can buy if needed or if I should avoid this altogether?

i use windows xp SP3
thnx

What's a good USB 3.0 hub?

I've got a late 2012 Mac mini. Mavericks OS (10.9.4). I have lots of USB devices, most of them of the 2.0 variety, a couple 3.0. I bought an inexpensive "USB 3.0" hub, and it causes the Mac not to wake from sleep mode. Instead it just powers off, and I have to unplug it from the wall before it will reboot. So I've gone back to my old 2.0 hub for the majority of my gear, but I've got a couple of drives that want 3.0 connections to function efficiently.
From what I can tell, it's the mixing of USB 2.0 and 3.0 that is causing problems. I'm not sure if the ports on the mini are paralleled, or are on separate power and driver chips. But so far, I can keep 3.0 devices plugged into the computer and 2.0 into my hub. That's fine 'til I need to plug in a 3.0 flash drive. I cannot make it work with the two hubs - I still have the same "no wake up" issue, unless nothing is plugged into the 3.0 hub. SO...
Who makes a robust USB 3.0 hub? The Belkin sold at the Apple website has roundly terrible reviews. I'd rather not be a guinea pig again. Does anyone have serious experience with these? It's not enough that you have one and it works. I'd like to know that you understand the workings a bit better than I do, and maybe can even explain to me what might be causing this incompatibility.
Thanks.

Re: Is there a USB 3.0 Hub that really works with the Mac Mini?

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
