Looking for USB 3.0 7 port HUB
I have been looking for a 7 Port USB Hub for my new IMAC 27" /3.4 i7/ 680 MX/ 32G/ 768 SSD/ I found TWO 7 Port that seams to have been upgraded. They both use the new VIA VL812 Chipset and say that they are compatible with Mac. Check these out and let me know what you think:
Anker® Uspeed USB 3.0 7 Port Hub + 1 Charging Port
4 1/2 Stars with 123 customer reviews
Anker® Uspeed USB 3.0 model [Anker® Uspeed USB 3.0 7 Port Hub + 1 Charging Port]
has the new VIA VL812 Chipset and is the only one, including the 4 port models, that tells about the update.
Windows XP / Vista / 7 / 8, Mac OS X
* Mac OS X Lion 10.7.4 users may experience unstable connections due to microchip incompatibility. Where possible, we recommend upgrading your OS X to Mountain Lion 10.8.2 or later.
If you encounter other performance concerns, please contact our customer support with your operating system information. We can then provide guidance on how to upgrade your hub's microchip firmware.
1. The charging port (5V 2A) is designed for charging your mobile devices only and will not support data transfers.
2. 2.4 GHz wireless devices, such as wireless keyboards and mouse adapters, may not work in close proximity to USB 3.0 devices or hubs. Connecting to a USB 2.0 port is recommended.
3. For maximum performance, connected devices should not exceed a combined current of 7A. Otherwise, output current may become unstable or disconnect entirely.
4. Some USB 3.0 devices require a direct connection to host USB 3.0 ports, including some USB 3.0 hard disks.
5. Please note that Apple now provides an official update for MacBook Air and MacBook Pro computers purchased in June 2012. This update improves USB 3.0 performance and compatibility and can be downloaded from the official Apple website as "MacBook Air and MacBook Pro Update 2.0." Please contact our support team if you cannot locate this update.

Good news Mac owners! Apple has released a graphics and USB focused update just for late model, Mid 2012 MacBook models including “all Mac notebooks released in June 2012.” This update “includes graphics performance and reliability enhancements and improves compatibility with some USB devices.”
As with any OS X update, simply choose updates in the App Store or choose Software Update from the Apple menu. Once all prerequisites are installed (which include 10.8.2), the update will appear.
Details on the update are rather sparse at the moment, however initial findings on the 11 inch Air I use as a primary work laptop are positive. After installing the update, some U3 Communicator HD docks which I had previously identified as defective actually worked consistently and at normal speeds.
I’ve also noticed better reliability on the arrangement of the quad display panel I use with the tiny Air and a set of our DisplayLink-based UGA-165 adapters. Previously I could virtually never reboot and have my display arrangement persist, but now that seems to have been corrected- however this probably has more to do with the unusual number of hubs and devices I go through in day to day equipment testing and the constant swapping of ports that comes with it.
One frustrating issue that persists is when an USB storage volume unexpectedly disconnects, finder will freeze- immediately if you instruct it to eject the improperly disconnected volume. Forcing a reboot corrects the issue, however the system is largely unresponsive until the reboot which of course could result in data loss.
We’d love to hear your input on how this update is affecting your Plugable devices on those shiny new MacBooks!
MacRumors of course has a thread on the topic with very active discussion: http://forums.macrumors.com/showthread.php?t=1486234
If anyone has either of these and has tested it let me know.
I may be careful about purchasing one of the other products unless they have been upgraded and say what is is compatible with.

Neither of these supposedly work properly (even with the latest firmware) with either the Macbook Pro Retina or the 2012 Mac Mini (I have the latter and I could really use a USB 3.0 hub at this point since I'm already out of ports without swapping something out and a USB 2.0 hub defeats the point of USB 3.0).
One site I looked at suggested the problem is now on Apple's side with those two models, but it didn't specify what the problem is (i.e. it suggests the same hubs work fine with all other Macs that have USB 3.0). I guess I'm just lucky that way.

I'm a mobile developer, and wanted a hub I could mount on the wall, connect several devices, and charge as well.
Most USB hubs will only provide 0.5A for charging, so they will charge an iPhone slowly, and an iPad not at all. (iPad will not charge with less than 1.1A).
I got one of these:
It's not cheap - a bit over $100. But it's metal, has mounting ears, 7 ports, and will provide up to 1.5A for charging on each port.
Now, for a bit of bad news:
- doesn't come with a power supply. This is because it's an industrial product. In most cases, systems these will be installed in (think metal cabinet in an auto plant) will have a suitable power bus.
- It works on any voltage from 7 to 30 volts. The higher the better. I tested it first on a bench supply, and then got a 50W universal laptop supply for about $30 at Fry's and set it to 20V. (It regulates this down to 5V of course.) If you're really going to draw 1.5A on every port, get a 75W supply.
This is actually a good thing. Most USB hubs come with inadequate power supplies. Better to let you choose your own.
- It will not charge an iPad while connected to your computer. Well, OK, it will, sort of. If you plug the iPad in when not connected to the computer it will start charging. If you then plug in your computer, it will continue to charge. (Should have checked the bench supply meter to see if it continues to charge at the same rate, but it has to be at least 1.1A...) And you can still access it with iTunes, XCode, etc.
I have some hope that there is some software that will enable charging without having to unplug and replug the computer.
- It will charge an iPhone at full rate. (I did check this with the bench supply meter, and did the math.. had to crank the voltage down to read the current accurately with only one port connected.) Presumably while the computer is connected. I haven't seen the problem with iPads where they will not start a charge if the computer is connected. But, then, they only need 0.5A to charge, which any USB hub will supply.
A Samsung Galaxy Tab or Galaxy Tab 2 will charge while the computer is plugged in, and will connect to the computer as well.
Using this with a 20-ft Accel UltraRun USB 3.0 active cable. But haven't tried with any actual USB 3 devices.
The computer is a 2012 Mac Mini.
Update: So, I have 6 devices on charge. Galaxy Tab, Galaxy Tab2, iPad 1, new iPad, iPhone 4S, iPhone 4. If I plug in the computer, it sees everything but the iPads.

How about this from Satechi?
As long as the quality is ok. And the controller - anyone know how the Genesys Logic GL3520 is compared to the more common preferable chips?
