External USB 3.0 Powered Hub?

I need a recommendation on which USB 3.0 powered hub I should purchase to go with my MacBook Pro 9,1. I only need 4 ports. The main purpose of the hub is to power a Matrox DualHead2Go display adapter. Quite frankly, the device is only USB 2, but I figured I might as well get today's technology. Any advice is greatly appreciated.

Yes, I know where to get them. What I wanted to know was which ones work best with the MacBook Pro. Believe it or not many of these devices have issues with Apple products for whatever reason. Just check the amazon.com reviews.

G580 external USB 2 and 3 hub connection

G580 Windows 8 64bit
I am unable to connect either USB2 or USB3 external hubs either powered or not to the notebook. The USB2 is locked out by windows and the USB3 crashes the system until removed. Intel driver update states that all Intel drivers are up to date. Both tested hubs work on an HP Vista 32bit laptop. Individual USB devices work fully so it seems to be hubs that are the problem. As there are only two USB3 ports available it would be convenient to use a hub occasionally. Any help would be gratefully received

I have a drive I had been using in a 2007 MacBook that I would like to "upgrade" to a compatible version of 10.7.4 (build 11E2705), but I am having trouble finding a way to get the version of the OS on the drive without affecting the data on the drive.
I had hoped that booting from the Recovery partion on the SSD would allow me to "Reinstall 10.7" to get a compatible version, but the drive still can not boot the 2012 MacBook Air.
I may try cloning next, moving directories I want to keep to the root level of the target drive, but I wish there was an easier way to "refresh" the install of the OS to a newer version for new hardware.
I also need to find a way to "refresh" the USB drive I have for installing 10.7, to make sure it has the ability to boot new hardware, since the original 10.7.4 USB install clone does not boot the newest laptops.

Airport Extreme, with Belkin usb 7 Port powered hub, with printer & 2 HD's

I have the Belkin usb 7 Port hub going into the Airport Extreme, my Macbook Pro sees the printer and prints fine, but doesn't see the 2 western digital mini hard drives My AE still has a green light. Is there something else I have to do? Thanks, Schooner

Hi Schooner17-
Are the drives bus-powered?
If so, do they work with the hub on a Mac? Do the drives work 1 at a time?
That hub might not supply enough juice to power both drives.

Will powered hub allow both a external hard drive and printer?

I have a 500g airport purchase in June 2009. I believe apple updated the products shortly afterwards. I am not home so don't have the model number. It has one USB port. Connecting one printer has worked with no problems. I just bought a 1T external hard drive and connected both the drive and printer to a powered hub. The hard drive is discovered by the airport but not the printer. What am I doing wrong?

Have you power cycled your complete network?
If not, power everything down, order is not important. Then start the modem first and let it run a few moments, then start your AirPort Extreme, then your hard drive, printer, and computers one at time, waiting a moment or two between each device.

Best external USB/FW hubs?

Been a little concerned by what readers have posted about the Belkin and other external USB/FW hubs -- even those posted on Apple's pages that list recommended hubs. Many folks have complained that these things get extremely hot....Anyone have recommendation. My problem with some hubs I've seen is that the way the ports are placed your cables fork out in off directions and make a mess. Some of the Belkin hubs are designed ifferently but people say these get very hot. Also, will FW devices really run properly through one of these hubs? Lastly, I see some hubs list as NOT requiring an AC power supply. Do non-powerd hubs really work reliably?

Hello David Chartrand,
Ok first a word on Hubs, especially, FireWire hubs.
Be aware that not all manufacturer's hubs are built to, or adhere to, 1394 standards, and may be damaged or cause system problems; If unsure, check with a potential supplier's support and get them to confirm that their product will comply with 1394 and work with Apple products Some don't.
The official FW specifications designate voltage from 8 - 30 Volts @+/- 10percent which means that if the vendors unit is not built to handle that voltage, it will fail.
Second, if your considering a Hub, you have a better chance of success with a Powered Hub, and, you have a better chance of success with a dedicated firewire hub rather than a combination USB/Firewire device
One example on the boards is a combo hub from IOGear which actually "popped" it's internal capacitors.
Hubs that are reported as working include but not limited to; Belkin Modelf5726slv and Belkin's 6-PortHub(F5U526APL). I use a good Macally Hub that ran about $ 80. and can be found here; http://www.macally.com/spec/firewire/connecting/hub_uf.html
Regarding iSight: I strongly suggest that you consider unplugging the iSight anytime your using any other FW device. If fact, since the iSight is never truly "off", just leave it unplugged until your actually going online to chat.
This applies weather you are using a hub or not, so unless you are chatting with a buddies, keep the iSight camera unplugged; hub or no hub. And you especially run a risk when doing backups to external FW HD's.
The only exception I've found is for some PowerBooks. From waht I can tell, the internal FW circuit/components used the other Mac series are not the same as used in my PB.
Hope this helps.
Respectfully,
Bill Gallagher

Can't see my External HDD via Airport Extreme & powered hub

I have Windows 7 laptop and it just can't seem to detect my HDD via the Airport Extreme wired through a powered hub. If I connect HDD directly to my laptop it can see the files.
First I had problems with seeing my printer and found out that I had to install Bonjour and that worked. Is there some kind of program to make my HDD accessible?

of course there is an easy way, however, it entails erasing all data on the drive. do you have access to a spare, "temporary", drive ?

Satellite M300: speach recognition works only with external usb hub

Hi All
I have the Satellite M300 which I was able to operate the speach recognition program prior to having the motherboard replaced due to the usb's failing.
I have found using the headset I cannot achieve high enough quality to operate it.
The only way I can operate the speach program is use an external usb hub with its own power supply.
Would the problem relate to the audio card or just simply not enough voltage?
And is there na fix?
Cheers
Craig

Hi
The notebooks USB ports provide a standard power of 500mA.
As I said this is a standard but in different cases the external 3rd party USB devices need more power.
For example one of my external USB 2.5 HDDs must be connected to two USB ports at the same time to ensure that the HDD would get enough power to work properly.
Your external card is not known to me but possibly it needs more power as usual.

External USB Hub?

I recently purchased a Sonnet Allegro USB 2.0 expansion card for my PowerMac 1.8GHz DP. Like others, I too am experiencing the dreaded deep sleep problem. I was wondering if anyone has had better success with an external USB hub. If so, which brand/model are you using?
Thanks,
Kelly

Hi-
You will have better luck (no sleep issues) using a USB hub. The only draw back is if you have multiple devices sending/receiving data at the same time, the transfer will slow down. One at a time, or static connection, no problem.
Here is a source of several quality hubs:

Trust Curve 7 Usb Powered Hub

Hi guys
I have bought a new usb powered hub, the Trust Curve 7.
It's look nice but it doesn't work properly.
The only way to make it work is to connect the hub without the power supply and only AFTER connect the power supply.
I think this thing isn't normal and i doesn't like this problem (ok it isn't a big problem but...)
Any IDEA
P.s i'm running OSX 10.7 on a macbook pro 13inch late 2011 (i5 dual core 4 gb ram)
I've try the hub on a windows computer and it's work well
Regards Andrea

It's not just you, I can't authorise my phone. It seemed to go down just after I started the update (it wasn't my fault though). I am using chrome, and it does not seem to be a firewall issue, or the bannerblock issue that I read about else where, since I dont have that program installed. Strange though how the support forum is still running. If I go to http://www.apple.com/support I get nothing, but googling topics allows me to see em.

External usb hub with Mac

I have a Belkin powered usb hub that I used to use with my Windows computer. Can I connect that to my Mac? When I try it does not power up (it must be connected to both a computer and power source) - the Mac does not seem to recognize it. Do I have to do something with the Mac?
Thanks...
PD

Yes you can connect it to your mac. The mac won't indicate that it's plugged in until you plug a usb device into the hub. For USB drives you're much better off using it plugged into the AC power source.

External USB Hub limit for Satellite Pro C650

Is there a limit to how many external usb ports you can connect through the Satellite Pro C650?
Wtih the four port hub I have, the ports seem to work individually and all devices work normally when plugged directly into the lap top, but when all devices are plugged into the hub and lap top combined, there are errors coming up.
Thanks,
Karyn

Well, I think this should not be a problem if the single USB hubs provide own power.
The point is that the single USB port provides common 500mA and if more devices would share the power from one USB port then it could be possible that the available 500mA would not be enough for all USB devices.

Time Machine times-out on external USB disk, but works on 2 others

Hello,
I wanted to share my experience, in case it is helpful to someone else. It appears that one of my external hard disks has a hardware fault, or that TM is overly sensitive to its state, thus preventing me using it for backup.
After upgrading from Tiger to Leopard on my Macbook Pro 2.16GHz, I had been trying over the last couple of days, without success, to backup using Time Machine to an external USB hard disk at work. It is a Maxtor disk in a BlueEye U235 case. On each attempt to make the initial backup, TM would copy between 2 and 25GB of data (of 75 total) to the disk, and then stall indefinately, without giving an error. (Ejecting the disk at this point and restarting the computer just lead to further problems with completing the backup that I won't go into here). I tried many times, each time reformatting the disk (with the GUID partition map), deleting the TM preference file, restarting and ensuring all other apps were not running. I was completely fed-up!
I subsequently tried backing up for the first time on a freshly re-partitioned (GUID map) Firewire 400 external disk (Prolific PL3507 Combo Device in a BlueEye O2 case) at home, and this worked perfectly the first time, taking a couple of hours. (All applications were closed at the time). Subsequent backups to this drive work fine.
I tried again with the disk at work and it continued to fail. Finally I decided to follow what was being thrown up to the system.log. I discovered that shortly after TM was stalling (somewhere between 10 and 40 mins after commencing the backup), repeated messages would appear in system.log saying "kernel IOSCSIPeripheralDeviceType00::setPowerState(0x4cbe100, 2 -> 1) timed out after 100683 ms" (with the "2 - > 1" and number of ms different each time), with a few minutes between each one. This suggested to me that there was some sort of intermittent failure of the disk, or the connection between the Macbook Pro and the disk, or something I don't understand. It is worth keeping in mind that this disk has been working perfectly for me - I've been backup up entire system to it every couple of days using SuperDuper, without any errors or problems.
So, I then tried using a different (LaCie) Firewire disk at work, and after reformatting / partitioning (GUID map), the backup to this worked perfectly the first time, with the entire ~68 GB completing in about 2 hours. (As an aside, switching between the TM backup disks at Home and Work works well - TM just catches up from where it last left off on the particular drive).
The message I wanted to convey is that, in my experience, TM may fail during a backup (stall in fact, as no explicit message was generated) to a disk that outwardly appears to be fully functional. I'm not sure if in my case there is a minor error with the disk, a fault with TM, or both. Interestingly, upon bringing the disk home today and switching it on it won't mount at all, on my computer or that of my partner. I'm not sure if the problems with TM were therefore indicative of imminent disk failure, or whether the trip home in the pannier on my bike has damaged the drive . So, if you're having this or some other difficulty, on a drive that you haven't purchased new, it may be worth considering that an unsuccessful TM backup may be due to a current, or imminent, problem with the disk.
Just my two cents worth.

Yes, I think you have a good point. The motivation for my post was just to make people aware - as there seems to be many people having problems with TM - that maybe the first drive you try, particularly if it is not new, may not work and that it is worth trying another if you can. Particularly in light of the fact that I didn't receive any explicit error messages, that is other than the one in the system.log file.
The USB disk was powered separately and was plugged directly into one of my USB ports (not via a hub). At the same time a USB mouse was plugged in. I think it is USB 2, but I'm not sure, and as it is not working now, I don't know how to check.
The rate at which data is copied to the two drives that work (via Firewire 400) seemed to be quite similar to the rate for the USB drive, until it bombed out.

Time Capsule 3rd Gen no longer sees External USB drive

Airport Utility 7.6.4 installed and no other updates are specified as avaiable.
For a while the external drive with two 1T Mac formatted partitions cannot be seen by network nor appears in Disk section of Airport Utility.
Mavericks used and all fully up to date.
Connecting drive to iMac and MBP directly allows use of the drive fine.
I think the firmware has stopped the external drive from being recognised. Did have the "USB Power" amber light occur some time ago but selected to ignore. External drive is powered of course.
Any ideas?

A Gen3 TC the USB port is seriously underpowered.
A powered hub is the first essential item to get this working. The fact that your disk is powered is insufficient.. I think also because of the limited number of USB devices the airport utility can work with.. even some powered hubs are simply not recognised.
For a while the external drive with two 1T Mac formatted partitions cannot be seen by network nor appears in Disk section of Airport Utility.
Mavericks used and all fully up to date.
The disk must appear in airport utility.
From there getting disks mounted in Mavericks can add another level of pain.. but recognition comes first.
The latest firmware is more likely a step backwards than anything.. I would downgrade the firmware to 7.6.1. Factory reset. Use all SMB naming, ie short, no spaces and pure alphanumeric.

External USB HDD not recognized by Time Capsule

Hi, I read that I should be able to extend my Time Capsule 500Gb with an external USB disk, and I bought a 500Gb Maxtor with external Power supply and USB 2 interface. I formatted it as mnentionen in all other threads I've read, but it dont show up in the Disks window in Airport Utility. Tried every combinations of restart procedures, plug/unplu, you name it. I tried vit a 2Gb USB Stick vith the same formatting - no problem, it showed up immediately.
Does the drive/USB interface have to be of a specific type (nothing like that is mentioned in the documentation), but it seems that there is an issue here?

I was having same trouble and finally found a solution by hooking my external drive to my time capsule through a powered USB router. When I did this, the disk was finally recognized. However I received a message from Airport Setup Utility that the external disk needed repair. (it had been formatted to a Mac OS Extended (Journaled) format previously).
I hooked up the external drive directly to my MBP with USB2 and reformatted/partitioned (1 partition) using the following: "Mac OS Extended (Journaled)" and the GUID partition scheme. (It should NOT be Master Boot Record (MBR).)
I then hooked the external back up to my Time Capsule thru my powered USB hub (it still would not show up using a direct connection) and I am able to see the drive fine now through AirPort Utility and able to archive directly to it. Hooray!
I hope this helps. Good luck!
