E7's USB On The Go and USB hubs

I'm curious, does E7's USB On The Go allow connecting multiple devices, i.e. a mouse and a keyboard through an USB hub?

Think that it has to be a single device and is all down to power requirement of device which must not exceed 200mA, so HDD would need to be powered.

HT1349 very slow external HDD and usb drive connected to Apple Extreme Router

Hello
So I got a western digital USB drive (500gig) and western digital Live 2TB.
I bought a new Apple Extreme router and connected them both.
USB drive and external hdd (WD Live 2TB) very slow when connected to Apple Extreme Router, using Lion 10.7 and updated both firmware for router, western digital and Airport Utility.
Slow means, it takes half an hour to copy 200 Mb of file to the WD Live 2TB, and its connected to my router with a gigabit ethernet cable!
Is someone else having the same problem, I thought even over usb I should get around 2-5mb range.
I am using Macbook Pro and 802.11n with Lion 10.7.2
Please Help

The USB WD 500 gig is connected to the Airport Extreme using a non-powered USB 2.0 hub, only two things a HP printer and the 500 gig is connected through it. I already formatted it to MAC OS Extended Journalled. ANd I think the speed didnt change.
For the WD 2TB Live I didnt format it to anything, started using it out of the box. I just updated its firmware. I was having the same speed even when I directly connected it to my Mac Book Pro using ethernet gigabit cable.
This WD 2TB Live doesnt have any USB 2.0 or USB 3.0 connectors, just the ethernet cable. I wasnt planning to carry it around. Just wanted to use it as a good ol NAS. So then I saw the fix somewhere and connected to this drive via AFP, afp://MyBookLive._afpovertcp._tcp.local/Public and it become suddenly very fast. Just like how it should be, I easily copied 20 gigs in around 20-25 minutes. (This was dirctly connected to my computer)
So then I thought my problem is solved and disconnected my WD Live and connected it back to the Apple Router again, and the speed became very slow again. Now both the USB 500 gig and this 2TB Live are slow.
Time machine is also very slow.
Thing is I also have a linux and windows machine(in repair, but should be up soon), Since apple is the newest computer I have, I want to make it work on this first. I dont want to use the MACosx journaled on the 2TB right now. Besides formatting the USB 500 gig to this format didnt help with my speed. So the problem can be elsewhere.
- I will try to get a powered USB hub as woodmeister50 suggested.
- I dont know how to connect via iCloud as cigame suggested
Please let me know if you guys have any suggestions. I have tested and returned enough routers in past few weeks. I really want it to work on this combination LionOSX + Airport Extreme + WD Live.
Thanks

External Hard Drive and USB Hubs

I need some help. I have a 320GB External Hard Drive which uses 2 USB Ports. I also have an external keyboard and mouse, using USB. I first purchased a 'passive' USB hub and the Mac was unable to recognize the External Hard Drive. So, I purchased a USB Hub powered by AC. The External Hard Drive lights up, but the Computer does not recognize it. Is there a recommended USB Hub that will allow the external hard drive to make the hand shake with my MacBook ?

Check with the drive manufacturer to determine if there is an alternative power source for the drive. I've never liked self powered drives and that so many made today require two USB ports is just one of the reasons why.

PPC Update 10.4.7 and USB hub problems

Hi,
After installing the PPC 10.4.7 combo update on my PowerPC G5 dual 2.7 GHz (4GB RAM) I have problems with my USB hub. The update seemed to have been installed properly (two reboots and no error messages) but since then my Kensington track ball does no longer work after power on. I have to detach and reattach the USB hub to reactivate the trackball. The problem does not occur after a restart (only after a power off/on cycle).
The USB hub did work before the update and I did not change the configuration after the update.
I hope someone can help me with this as it is very frustrating for me to crawl under my desk to detach and reattach the USB hub every time I turn on my mac...
Thanks for any help!

I can't help you, but I wanted to say that I have a similar problem. After a sleep/wake, my hub doesn't wake up. I have done a bunch of troubleshooting, including buying a new hub, which did not solve the problem (I took it back). When I reboot, all is back to normal. I have a 2001 Powermac G4 with a Sonnet Allegro USB 2.0 card that I added, over a year ago. It has worked fine since I bought it. Now, after upgrading to OS 10.4.7, I have this sleep/wake problem with the USB hub (Keyspan).
I have checked the ports on the USB card and I have found that at least one port is dead when I wake the machine back up. I can switch over devices around and they work in the remaining three ports on the board. The hub, however, does not work at all in any port, until after a reboot. There must be some special signal that the board sends out to the hub that resets it after a boot. I don't know. It's very frustrating, though. I don't like waiting for a reboot, which is why I have gotten in the habit of using sleep.
Maybe someone else has some idea what might be causing this problem? It could be just a coincidence that it started soon after the OS update. Maybe the board just decided to go bad at this particular time...?

Airport Extreme and USB hub

Okay I connected a hub to my USB on the airport extreme. Now I can see both hard drives however I get an IP address conflict and the network basically shuts down. Is there something I am missing here?

Try reading the entire conversation, Duane, and you'll realize that I'm fully aware of the fact that he's talking about a USB hub. And let me point out the fact that your misunderstanding makes no sense because even if I had thought he was talking about an ethernet hub, an ethernet hub has no IP address of its own.
His problem is that he gets an error message indicating that an IP that has already been allocated is being used by another device. A USB hub gets no IP nor does a simple USB external drive. Still, when he plugs in the hub that error message pops up. Why? The only explanation I could come up with is that one of the drives he is attaching to the USB hub isn't a standard external USB drive.
Have I connected all the dots for you okay?

Airport Extreme and USB Hub + Printer and Hard Drives

I have been using my Airport Extreme with a USB hub with 2 external hard drives and one printer for a while now and everything has been going fine. However, recently, the hard drives have stopped registering when I have the USB hub plugged in. I have plugged the hub directly into my computer with everything attached and it works fine but the moment I plug the hub into the Airport, nothing shows up except that the printer still works.
Does anyone know what is wrong? Thanks!

Hi, I've had this same problem now for more than 1 year, and nothing had solved it, until recently. I think I know what the problem is.
It turns out that not all USB 2.0 hard drive enclosures are the same. I had been using "Metalgear Substance II" enclosures for my 500-GB drives, and I had assumed all along that these were fine... I had assumed that one USB 2.0 enclosure was as good as the next USB 2.0 enclosure. WRONG!!!
By accident, I noticed that the drive-to-drive copy times from MetalGear USB 2.0 boxes was about 22 hours for a full 450-GByte transfer of information, while placing the SAME drive into a MacAlley enclosure reduced the copy time down from 22 hours to 6 hours... About 3.5 times faster!!! This means that the piece of crud Metalgear boxes I had been using for my network drives were ssssllllooowwww.
A big bright light blinked on in my head regarding my issues and problems with the Apple Airport Extreme Base-station and all of the problems I'd had with multiple drives, the AEBS locking up etc.. All of my issues had been associated with using the el-cheapo Metalgear enclosures.
As soon as I replaced the Metalgear USB boxes with MacAlley boxes, everything started to work great. No more issues with my Airport locking up. None. Problem fixed. Problem solved.
I can only assume that NOT ALL USB 2.0 BOXES ARE THE SAME. USB 2.0 does not mean that the transfer rates will actually be at 480-mbps. Quality matters. DO NOT USE METALGEAR BOXES WITH APPLE EXTREME. There may be other brands with suck just as much. I can vouch for the MacAlley boxes. They work great... and there may be other boxes that work too. There must be some issue with Apple Airport Base Station timing out on slower USB 2.0 crapola equipment... something that causes it to hang.
Anyway, I hope this helps. My problems are solved since going to the MacAlley enclosures.

Yosemite 10.10.2 and USB hub issue

Hi there,
I got a MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite last December and bought a USB hub (four-port) on Jan 3rd. I was using it for one month with
OS X Yosemite 10.10.1 without any problems.
On Feb 4th I switch to OS X Yosemite 10.10.2 and I started to have 2-4 times the following issue per day:
- mac frozen (I cannot use the keyboard or the mouse) but I see that the clock is working. No other way that a hard reset.
I did check memory and hard drive and everything is ok
- for one week I did use the USB hub and didn't have any issue
- I started again and less than 24h hour later I got a similar issue !
I am not 100% sure this related to 10.10.2 but before with 10.10.1 I had no issue ! I am not sure to understand how a USB hub can crash a Mac.
I try to look a the Consol application but couldn't really identify a common issue a the time of the issue but maybe some messages like that :
Any idea or suggestion ?
Thanks
Cheers

Macbook Pro and USB HUB

Let me start with this. My Macbook Pro (4 yrs old) has only 2 usb ports, so I went to buy a USB HUB. I bought Pentagram HUB USB 4P Passive [P 1224-3] , I plug it in. Small green light on it is on. Then I plug the printer, wireless mouse receiver and a WD Passport 160GB. None of the above are working. (The printer has it's own power cable). Where's the problem. Is it the HUB or something else?
Please help.

It's the hub. "Passive" is the key to your problem.
An "active" or "powered" hub prevents devices from drawing more power than the ports can deliver. Your big consumer is the WD passport drive. You're powering not only the electronics but also an electric motor.
If you mainly need the hub for working in a home or office environment, always go for the powered type. The passive hub may work for travel as long as you limit the number of devices.

External hdd and usb issue

Hey there... May sound like a silly question but I am having a problem with an external hdd.
I recently bought a brand-spanking new macbook pro w. retina and can't find my external hdd when I plug it in.
Theoretically, there should be no problem between the old hdd's usb 2 and the new macbook's usb 3, and the new computer is only a week old, so what I was wondering was whether anyone knew if there might be any interface issue between the old hdd (can't remember exactly what the os was - it was either leopard or snow leopard...10.6.something as i recall) and the new one (10.8.3)?
Or should I just go ahead and weep over the old lost hdd?
Appreciate any help

HT2494 imac and usb hub not working

My iMac won't recognize anything plugged into my powered usb hub. Its a dynex from Best Buy. Only 2 months old and gets more finicky with time. Nothing of significance power is plugged into it. Have a flash drive and small garmin gps I download info off of. Any suggestions?

Have you tried other ports to plug the hub into?

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.

Midi and USB hub on new MINI causes kernal panics.

I purchased the lozenge shaped Belkin 4-port powered USB2.0 hub from the apple store yesterday. I had two midi interfaces plugged into it. As soon as MIDI hits it (from Logic Pro 7) the Mini has a Kernel Panic that requires a power cycle. Using the devices plugged directly into the MINI works fine.
Any other experience similar situations?
Thanks
Chris

Hi Chris,
Does the USB hub come with a power adapter?Some midi interfaces need the 5 volts from the usb bus in order to work properly(I have an edirol that only works this way,unless I power it with it's own power supply).

Laggy window performance with external monitor and USB hub after 8.1 -- possible cause found

I have the Yoga 11s which I've been using in conjunction with a Plugable UD-3900 for a few weeks now. Everything has worked very well, especially with external display, keyboard, mouse, and ethernet plugged into the hub.
After upgrading to 8.1 the other day, I began getting very noticeable window and mouse lag on the external monitor. Dragging windows would jump around, aero peek renders were slow, and the 'ribbon' screen saver would pixelate and was slow to wake up.
I installed the updated DisplayLink drivers, and also all the updated Lenovo drivers, but the problem remained. This morning I was trying different ideas and found something very interesting:
The configuration I use when attached to the UD-3900 is to have the keyboard flipped under and the display flipped up in the "stand" so I can use it as a second monitor. Of course when you do that, the Yoga turns off the keyboard & touchpad so they don't get accidentally pressed.
Just for kicks, I decided to flip the keyboard back around and try using the touchpad to move windows around on the extended monitor. Surprise: the laggy window dragging and rendering was gone. And then even more surprising, when going back to the wireless mouse while still in 'laptop' configuration, everything continued to work well -- no lag.
I thought maybe it was an incompatibility with the Logitech wireless USB keyboard/mouse itself, so I disconnected it. However, I also have a bluetooth Microsoft mouse, and it does the exact same thing: With laptop keyboard flipped back & disabled, window drags & aero peek renders lag. As soon as I activate the touchpad, lag is gone, and the BT mouse behaves normally.
So, it seems to be some kind of interaction between the automatic disabling of the Yoga's keyboard/touchpad and any external mouse. Has anyone else seen anything similar? Any ideas on how to solve so I can use the Yoga in the stand configuration?

Just to close the loop on this, I've determined that the cause of my issue is the Intel Dynamic Platform and Thermal Framework software/driver. I've disabled in the BIOS for now, and the machine is working very well. Will look for an update from Lenovo to address more definitively.

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:
