Right USB port has exactly the same tasks as the left side one?

I v a USB sound cart (MBox 1 by digidesign)
Wen I use togeteher with it an external hard disk connected with USB (some time the fire wire is occupied by another hard disk) if the USB hard disk is on the left side (looking the screen) and the MBox on the right...the hard disk start making a "periodic" sound similar to a metronome and it doesn't run....if I invert the positions it work fine.
Is this normal ? The USB port works fine with the MBOX but with the USB Lacie hard disk is not working....the other USB port is working fine with both.
Is an hardweare problem ? Since my MBP is 2 weeks old I would consider the idea to send it to fix this problem.

This sounds like the same problem I'm having with my MacBook Pro. For whatever reason the USB port on the left side of the machine does not provide sufficient power to spin up any USB bus-powered hard drive. The USB port on the right side of the machine works just fine for external USB bus-powered devices.
I have sent my system back to Apple to have this problem fixed. Unfortunately, their "repair" did not fix the problem at all. I just got off the phone with Apple again, and they are going to re-repair my system again.
I would suggest that you try an experiment with your USB hard-drive. Just plug it into the left side port without having any other USB devices plugged into the right side. Check if the drive just clicks and does not spin up. Then try the same thing with the USB port on the right side.
If you find that the drive works fine on the right, but not on the left, I would call Apple support for a repair. I do not think this is an isolated issue, but rather is probably a design issue with the systems. The issue should have been caught during testing before the MacBook Pro went into production, but obviously that is not the case. Hopefully if enough people complain about this Apple will take it seriously and fix the problem.
Good luck.

USB Port has exceeded the power li

Each time i connect my player to either a laptop or desktop, I get the following message:?A usb device has exceeded the power limit on it's hub port?Now I've tried putting it in different usb ports but it keeps saying the same thing. Can anyone help please?

MIDI controller is working in the right usb port, but it doesn't in left

Hello all,
I have this strange problem, yesterday i bought MIDI keyboards it's M-AUDIO Keystation Mini 32
The problem is that when i connect it to right USB port it works flawlessly, but when i connect it to my left USB port - my macbook pro recognizes the device but it doesn't send any midi data - to put it in other way: it is not working.
I have checked, everything is working fine In the LEFT usb port( wireless mouse, external HDD, Flash drives, Iphone) except my MIDI Keyboard.
Can anyone help? i've been searching for days for the solution, but, i'm out of ideas.

Hey,
i have the exact same problem! I was in the apple store and they replaced my macbook. then it just worked fine for a few days and now the problems is there again.
Do you already have a solution?

My problem - when syncing and error messages comes up: iTunes could not sync calendars to the iPhone because an error occurred while margin data." I've tried turning the phone off and back on, & tried both USB ports but get the same thing. What can I do next since it doesn't give me even one clue as to what the error would be?

Before I started to resync calendars one by one as suggested in the troubleshooting article, I remembered something that came up in a sync when I first attempted : a 'which one do you want to keep' message about a repeating calendar event, which came up with three options, one from Calendar, and two from iCal on the phone. I deleted that event, then went through the calendar resync one by one, and all seems OK now.
In Music there is a way to find 'ghost' items that show up as grayed-out on the menus, so that you can try to reassociate or delete them. It would be nice to have a similar way to work with Calendar!
Thanks for pointing me to the right article.

Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port.

When I attempt to install an external DVD/CDRW I receive the following:
Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port.
I am forced to reset.

I would guess that your external DVD is drawing too much power from the USB port, and could be one of the older units; newer units are usually more power efficient. Such device usually come with a USB cable with two USB connectors that can draw power from two USB ports simultaneously. You may be able to get such cable separately but since the two USB ports are located at extreme ends in the S10, you may want to check that the cable come with the USB connectors with sufficient length to reach both the USB ports simultaneously.

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

USB port has power but isn't working

Hey guys,
One of my usb ports has decided to stop working properly, I'm still able to use peripherals which ONLY require power, an example being my external fan which works fine in that port.
However, I'm unable to use my mouse or any storage device in the port.
The lights(if any) on the devices will light up as normal but will not do much other than that.
I have not made any major changes since the last time the port was successfully used, it has just stopped working.
I've restarted multiple times and the issue persists.
All other usb ports work perfectly normal, no issues.
Specs:
Pavilion DV6 7029TX
Running Windows 8 Pro 64bit
All up to date with windows updates
If any other info is required please let me know.
I'd appreciate any and all help someone may provide in helping me get to the bottom of this.
Cheers.

Hello -Brendan-,
I think we should try ALL the drivers. The Chipset drivers are the drivers for your motherboard and the other drivers are for the individual on-board devices. I am thinking we should do your Chipset drivers first and then your on-board drivers. Like building a house we should ensure the foundation is solid before adding the house on top. What I would like you to do is to download and install ALL the drivers from the HP Pavilion dv6-7029tx Entertainment Notebook PC Drivers page. Ensure you download and install the Chipset drivers first, after that it does not matter which order you install the drivers.
Please re-post with the results on either of the threads you have on the go. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Right USB Port faster than left (MBP 15 2013) ?

Hello guys,
I just installed Drive Genius 3. Im assuming bad sectors on my external hard drive. When I connect the drive on the left usb next to thunderbolt normal scanning says can take up to 8/9 hours.
Plugging it into the right USB port only says around 3,5 hrs.
Is there a difference in speed?
One more question:
Dont all new drives have SMART? My latest WD Elements says it has no SMART Status. So I cant find out any bad sectors except by doing a scan with Drive Genius?

The thing is, when I use an adaptor with the keyboard, it works fine in Logic. But the USB port cant seem to power the keybaord like the left one can. Could the USB port on the left really be broken if it is working with Logic with the adaptor?

Macbook Pro right USB port disconnects

Hi - When using the dialup modem adapter in the right USB port it will disconnect after 3-4 minutes but works fine in the left port. Flash drives & scanner seem to work OK in the right.
Also, a friend has computerized embroidery sewing machine and the right port does not recognized it but the left does on her MAC.
Are Macs were bought a couple weeks apart.
Is there a setting for each USB port that maybe wrong or is this just a defect?

Well, does that link...

still lock up your Mac? No way it should have any such effect.

Hp split x2 right USB port not working

I've had my hp split x2 for about a month now. Today I was using a wireless mouse in the right USB port. I closed the screen because I was going out and when I returned the right USB port was no longer recognizing the mouse. I plug the mouse into the left port everything works fine. I have an external hard drive that lights up when plugged into the USB slot. So I tried that in the right port. The drive lights up meaning the port is powering it but the computer does not recognize its there. I fiddle with the device drivers uninstalling and reinstalling the USB drivers. Nothing worked. I even went as far as reformatting windows. Still not working. Now I have a case open with hp to send it in to get it fixed but if there is a possible fix I would be much appreciated in hearing one. Thank you.

I'm having the same problem with my left USB port. What do you find out?

Right USB Port not reading External HD

I'm using Mid 2014, Retina, 13-inch, Macbook Pro. I noticed that my right USB Port is not reading my 1 TB WD External HD but able to use mouse. How to fix it?

According to the fount of knowledge that is Wikipedia…
https://en.wikipedia.org/wiki/USB
As with previous USB versions, USB 3.0 ports come in low-power and high-power variants, providing 150 mA and 900 mA respectively, while simultaneously transmitting data at SuperSpeed rates.[25] Additionally, there is a Battery Charging Specification (Version 1.2 – December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.
It doesn't make sense to me that a 'low power' USB port would output 500ma unless it was working in USB2 mode.
A unit load is defined as 100 mA in USB 1.x and 2.0, and 150 mA in USB 3.0. A device may draw a maximum of five unit loads (500 mA) from a port in USB 1.x and 2.0, or six unit loads (900 mA) in USB 3.0.
You may want to get the genius to confirm the spec for both ports if you go along to a store, I guess they may have limitations.
I would also boot into recovery mode just to see if the disk pops up in Disk Utility via both ports - that could indicate the port is being rendered useless by the OS.
Apologies, you appear to have tried that already.

I am not 100% what isn't allowed.. but I am assuming you want to spread the backup across the two disks.. internal TC and 6TB external.. this is not possible.. It has to be one or the other. TC has no way to build a raid JBOD or anything else. Nor would you want to as that is the most likely to fail and kill your data.
Let me add, backing up 6TB over USB on TC.. will be the most excruciating experience of your life.. cf child birth or passing kidney stones.. large ones.. being the male equivalent.

I have an Imac running snow leopard and have recently installed a cannon i-sensys lbp7750Cdn printer since then I can't get the printer working and the air port has lost the DNS servers; if it ever had them!!! but it dose not look happy. Can any one help

I have an Imac running snow leopard and have recently installed a cannon i-sensys lbp7750Cdn printer since then I can't get the printer working and the air port has lost the DNS servers; if it ever had them!!! but it dose not look happy and it is telling me so. Can any one help please?

Snow Leopard breaks quite a few drivers - my Canon exhibited the same problem.
I eventually found updated drivers on the Canon website. You can try that with the HP, but if the all-in-one is more than a year or so old, don't hold your breath.
You can also try Software Update to see if it will offer new drivers, or failing that go to the Support Downloads site and search for HP updates.
In fact there's a new one for HP at the top of the list just now.
You may not necessarily want the latest one, though - check the specs to see if your model is covered; if not, search for the previous update etc.

PLZ HLP:A USB device has exceeded the power limits of its hub p

Hi, hope you can help me, and thanks for reading.
I have a Dell Inspiron 500 with XP SP2.
I also have a Zen Micro 6 GB that works perfectly.
Recently I attached the Zen to the laptop and every time I receive this message:
"PowerSurgeOn Hub Port. A USB device has exceeded the power limits of its hub port."
I take the Zen to my work computer and it works perfectly.
?What is the problem?
Thanks,
Regards,
Lorenzo

^your laptop is unable to provide enough power to charge your Zen Micro.
If it has other USB ports, try using them.
It may be a case that the laptop is not designed to power external devices like the Zen Micro.

Right USB port has exactly the same tasks as the left side one?
