USB port seems a lot quicker than my tower?

I just noticed that transferring files from my usb key on my new MacBook Pro seems a lot faster than doing this on my old G5, even though they both use the same speed USB 2.0 port.
Is there something about this notebook that makes it quicker?
Thanks.

Most likely it's through better driver support.

Is there a MBPro equivalent to PMU reset on my Pismo:
Unplug from AC
remove battery
hold down power button 10+ seconds
replace battery
Plug up
power on
this is also supposed to zap the NVRAM. zapping PRAM is always recommended in this process for good measure.

All USB ports seem to stop working "randomly" but some remain functioning until unplugged and plugged back in. [WINDOWS 8.1]

The devices that die right away are the network adapter and any USB memory stick plugged in, they still have their lights and all running but aren't recognized in "This PC" and the network adapter isn't found in "Control Panel\Network and
Internet\Network Connections".
My keyboard, wireless mouse that runs through the keyboard's USB ports and the external HDD remains functional UNTIL I pull the plug on them, after that plugging them back in does nothing.
I put randomly in quotations because it seems to fail more often when I download something at speeds over 3Mb/s, for an example downloading Hearthstone through the Battle.Net client will more often than not make the issue happen after a little bit. BUT it still
happens randomly during NO network load what-so-ever.
Parts:
CPU| FX-8350
GPU| Radeon 5850
Motherboard | Crosshair IV Formula
RAM | 2x DDR3
PSU | 700W Gold
SSD| Evo 850
OS | Windows 8.1
I HAVE:
* [Downloaded these chipset drivers](http://support.amd.com/en-us/download/chipset?os=Windows%208.1%20-%2064)
* Installed all Windows 7 drivers I could find except the BIOS ones due to lack of Windows 8.1 drivers from http://www.asus.com/Motherboards/CROSSHAIR_IV_FORMULA/HelpDesk_Download/
* Turned off "Allow this computer to turn off this device to save power" in Device Manager for ALL devices in the USB tab that had the option, and the Network tab.
* Set the Power Options to high performance and disabled "USB Selective Suspended Setting"
I simply don't know what to do anymore and it's breaking me down, I need this fixed before the weekend or the LAN I'm planning to go to will be a disaster and I'll probably go insane trying to solve this myself.
Just tell me whatever more information you could need and I'll supply it, I'm desperate to get this solved.
**I never had any of these issues on my old PC that had different parts but the same network adapter and external HDD so they are not to blame for this, same for keyboard and mouse.**

Hey, I hope this helps you out a bit... I have had the same issue on my Asus K55A notebook with Win8.1 Pro x64 from the beginning! Thru my extensive research I found something interesting and the possible cause to all this! What I found was that by design
the xHCI Host Controller has virtual HS 2.0 Ports linked to the 3.0 Ports... Enabling compatibility with 2.0 devices ok... What happens is that the xHCI stack is unstable just like you say... The ONLY WAY I was able to fix the problem was by unlocking the
UEFI/BIOS to allow me full access to USB Configurations... I had to disable 2 of the HS ports under the xHCI Controller since I have only 2x 3.0 ports... This allowed 3.0 devices to be enumerated correctly under the xHCI stack and 2.0 devices now were enumerated
under the EHCI 2.0 stack... That's what worked in my case... I'm still digging around for more info about this issue because I find it so odd that no one discovered this when designing xHCI stacks and drivers at MS for Win8/8.1 x64... I hope I shed some light
on this issue... Good luck and keep us posted!
Hi, Sebastian. I have the same problem but i'm getting crazy trying to solve it. Can you help me to unlock the UEFI to access full USB config? and give me some suggestions on how to solve the problem?

Thanks in advance!

USB ports seem to be underpowered

Hello.
I have a Patriot USB flash drive that frequently cannot mount when plugged into my iMac (OS 10.4.11). The drive mounts fine in my Macbook and Dell PC. If I let the drive sit in the port long enough, it sometimes accumulates enough power to work. And this is with all other USB periferals (except keyboard and mouse) unplugged.
And I have other problems with other USB devices, where the devices cannot be seen by the computer because they are not receiving enough USB power.
Any thoughts?
Thanks

Thanks for the suggestions, but yes, I have tried all three USB ports, and the behavior is exactly the same.
Also, the drive is properly formated. It works absolutely fine on my Macbook. Never any problems.
I have also had erratic performance with my USB Hub (D-link DUB-H7). And a quick scan of the reviews for this product at Amazon indicates that those with iMacs have erratic performance also, while those using it with other computers seem to have zero problems. Perhaps there is an iMac specific problem that develops (at least with certain iMacs) and USB ports.
I wonder if resetting power management will help?

HELP ! My USB ports seems to be deads !

Hello,
For my weekly back-up, I use an USB external HDD that have to use 2 USB ports.
In order to use only 1 port, I've connected my external HDD to a power supply.
Unfortunately, it seems that the power suplly I used wasn't the goos one for my HDD and when I've connected the HDD to the MacBook, the MacBook as turned off. So, I quickly have unplugged the USB and I've reboot the MacBook but it told me that the USB port was using to much energy and that it will be disabled.
So, I've unplugged all the rest on the USB (my keyboard with my mouse plugged-on) and I've reboot the MacBook. Unfortunately, it told me again that the USB port was using too much energy.
So, I turned off the MacBook, unplugged the power supply and removed the battery and I plugged my mouse to the 2 USB ports in order to unload a possible capacitor too much loaded and I turned my MacBook back on.
Now, I don't have any message but the 2 USB ports are not working. Here is a capture of my System Informations :
http://dl.dropbox.com/u/331131/info_sys.png
I searched how to activate my ports on the Internet but the only solution I found was to reboot the laptop, and it's not working for me...
Do you know how to activate manually the USB ports or do I have to make my mourning ?
Thanks,

Bonjour,
Pour mon back-up hebdomadaire, j'utilise un disque dur externe en USB.
Malheureusement, celui-ci m'oblige à le branché sur les 2 ports USB de mon MacBook, ce qui fait que c'est assez chiant de bosser dessus pendant que le disque dur est branché.
J'ai remarqué que mon boîtier de disque dur avait une prise pour alimentation externe. J'ai donc branché la première alimentation qui m'est tombée sous la main et qui semblait être faite pour lui. Comme ça, j'avais l'intention de ne brancher le boîtier qu'à un seul port USB et ça aurait dû fonctionner...
Sauf que voilà, de toute évidence, l'alimentation utilisée n'était pas la bonne et lorsque j'ai branché le boîtier, le MacBook s'est éteint.
Je me suis empressé de le débranché et j'ai redémarré le MacBook.
Au démarrage, celui-ci me dit qu'un port USB consomme trop d'énergie et qu'il sera désactivé. Et effectivement, il l'est. Je redémarre donc en débranchant tout ce qu'i y a sur les ports USB (mon clavier et la souris qui est branchée dessus) et je redémarre. Rebelotte, le même message qui revient. Je l'éteint donc, le débranche, enlève la batterie, branche ma souris en USB pour "décharger" un éventuel condensateur trop chargé et je relance la bécane avec la batterie et l'alimentation.
J'ai plus le message, donc j'ai un peu d'espoir qui revient et je rebranche ma souris pour tester le port... rien.
Je redémarre, re-test... rien.
Je vais dans les informations système, et j'ai ça :
http://dl.dropbox.com/u/331131/info_sys.png
J'ai cherché comment ré-activer mes ports USB mais la seule solution que j'ai trouvée c'est de redémarrer la machine, ce qui ne marche pas dans mon cas.
Avez-vous une solution pour ré-activer mes ports ou dois-je faire mon deuil ?
Merci.

Try to reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) on your computer. Turn off your computer, then restart it and immediately press and hold the "Command," "Option," "P" and "R" keys on the keyboard. Release the keys after you hear the startup chime for the third time and your computer should boot normally.
To avoid such issues you may use a self-powered USB hub (one that comes with a separate power brick).

HT1533 i have no control of my new imac as windows 7 starts suggesting system repair and usb ports seem to be

how do i regain control of my mac to unhang it from needing system repair (windows7)
should osx on an sd card work (only option?)!
any response would greatly encourage success.

If you are having Windows issues then you need to be in touch with a Windows forum for assistance. You did not state how you run Windows (Boot Camp, Parallels, Fusion, etc....) so I'm afraid I can't provide any more help than that. If you happen to use Boot Camp, there is a Boot Camp forum available which is where the Boot Camp and Windows gurus tend to hang out. The same would hold true if you use virtualization apps such as Fusion or Parallels.
Good luck.

Neither usb port seems to be working

Any ideas? Have tried to use my usual memory stick this am but it will not work in either port. was working on Friday.

Hi,
Thanks for your reply. Am away from home and only have this stick with me. However, has tried in another computer, working fine.

Usb ports seems loose

I just bought a new console, soon as I plugged my controller into the Ps4 console for the *first few setting* i thought they were maybe defect.
I see some old posts about that, just wanna know if thats normal, am I the only one with that problems these days?

I think its the whole socket, connector looks fine and connect well but i can move it up-down and left-right about 3mm
Edit: went to the retailer and tried a new controller, same *problem*

USB Ports on 3 month old Satellite C655-S5049 do not work-even after Recovery to "Out-of-Box" state

Hello - Hoping someone can help with another suggestion- it doesn't look good.
Both USB ports on my wife's 3 month old Satellite C655-S5049 are non-functional with any USB device. Flash drives, wireless mouse, and external hard drive (powered) that all work on all of my other computers, do not work in either of this laptop's USB ports.
This problem seems to have developed gradually, and became noticeable previously as non-responsiveness in the wireless mouse, which gradually became a concern, with the computer appearing to freeze or lock-up - probably because of the number of times the mouse was clicked on shortcuts and executables before something happened.
The ports are now completely "dead"- no recognition of anything inserted once the computer is up and running.
There appears to be a thermal component involved, since I was able to get the devices recognized and working for up to a minute when booting the computer with the devices in the ports after it had been off for several hours after I did the default state recovery. The flash drive and mouse were recognized, drivers loaded message, but they then went to "unplugged" before I could get the cursor moving. I was able to access the flash drive, since I did it as soon as the driver loaded, but then it disappeared ("un-plugged" itself in the driver loaded message box). I can also get them recognized from this COLD boot state when I immediately plug them in once Windows 7 (64) loads, but they quickly disappear. If I wait a few minutes before re-booting, they flash during the Windows boot, but drop-out before it completes. If I wait 3-4 hours to re-boot, they flash (are recognized) for about a minute (Windows completely loads), but then they drop out.
I tried all of the suggestions on this board (and others) before doing a Recovery to Factory Default state. I have tried it with the original version 1.20 Bios, and with the version 1.50 Bios update. All driver updates have been downloaded and installed. The laptop does occasionally lock-up at the Toshiba screen during boot, and is verrrry slow in some operations (2 hours to do the recovery discs). The only other noticeable problem (at this time) is an occasional drop-out of wireless (Atheros AR9285) connectivity, which I have been blaming on the router since it is sporadic and infrequent (not consistent with the thermal argument). These problems are all after the Factory Default State recovery operation, so my assumption is that they are hardware based.
Any suggestions for a solution? This is a standard spec Satellite C655-S5049 that I was considering adding another 2GB memory to, but now I am unsure of its' future. A laptop cooler that runs from a USB port seems counter-productive.
I am technically capable, so you can be much briefer in your response than I have been in trying to fully detail the problems. This isn't the NVidia chip, but it does bring back memories of laptops past.
Thanks for any help,
G

My Macbook Pro Retina's USB port on the right side not working at all

Dear all,
I received my macbook pro 15inch with retina display a week ago, but not until today had I got the chance to use the USB port on the right side, only to find out that it is not connecting to anything at all. I have tried to use my iPhone 4 and iPad 3 with two different cables, my USB thumb drive, and my Blackberry 9900, none of them are charging nor shown in iTunes/Finder. All of above works on the left and on other windows machines too.
I'm also not able to charge my Blackberry with the usb port on the left side, thought it would pop up a message saying "charging not supported" on the phone.
For you information, I have applied both updates including the one released few days ago. I have also tried to reset the PRAM. Also, I have migrated from my old late 2008 13inch unibody Macbook using Migration Assistant, not sure if this would affect anything.
I'm aware that there have been reports and discussions regarding the USB port not been able to run devices on 3.0 speed, but I wonder if anyone else have the same problem with me, where the port simply not connecting to anything at all?

I also have a problem with the USB port on the right side of my Retina MBP. The USB3.0 port on the left side works fine, even with high speed external SSD enclosures, like the OWC Mercury Extreme Pro 6G which enables me to copy large files at a sustained rate of 160-170MB/sec. Wow USB3.0 and the Mercury SSD is a FAAAAST combination connected to the Retina MBP.
However, like the forum entries about the USB3.0 ports in general on the new Retina MBP, the USB3.0 port on the RIGHT side is plagued with dropping intermittently, disconnecting my external hard drives while copying large files AS WELL AS disconnecting while just sitting there connected to an external hard drive and doing nothing.
Therefore, since I don't feel like returning my Retina MBP and waiting weeks for a replacement, I have chosen to only use the left side USB3.0 port for now.
I have my suspicions about why the right side USB port might be more problematic than the left side one. I found this older post on the internet about how "Not all USB ports are created equal on MacBooks..." that talks about how on older models of MacBooks one of the USB ports shares a USB hub with multiple other devices like the iSight camera etc. therefore making it less tolerant of heavy traffic or something like that. (http://www.wired.com/gadgetlab/2008/05/the-macbook-all/)
Therefore, I wonder if the right side USB port is sharing a USB internal hub where-as the left side one is more 'dedicated' and therefore in my case able to handle the high speed transfers/traffic I am throwing at it with my external SSDs.
I have also read that USB3.0 in general, on non-Macs, has had trouble for years. For instance, some forum entries on Apple Support Communities and other non-Apple forums has made mention that 'they' are not surprised at the problems encountered on USB3.0 external hard drives connected to the Retina MBP because Windows laptops have had a lot of flakey problems with USB3.0 for 'years'.
Also, I have recently purchased a "Buffalo" external Thunderbolt 1TB drive from OWC and have been doing Clones onto that drive for several weeks. I use SuperDuper to clone >600GB of data on my 768GB Retina MBP several times a week. And, I have (knock on wood) not had any problems with the stability of my externally connected Thunderbolt drive.
So, in my case, I am racking it up to high-speed stresses on the USB3.0 ports at least in part...and perhaps the possibility that the LEFT side USB port on the Retina MBP is more dependable and/or a more dedicated USB port than the right side one.
This doesn't really solve your problem, but it may at least help you feel like you are not alone.

Flash drive is physically stuck in one of my USB ports (HP 2000)

There is a flash drive that has been physically stuck in one of the USB ports of my HP 2000 for a few days now.
(1) I've tried using physical force to pull it out (e.g. pulling while moving the flash drive in a circular motion, pulling straight, pulling to the sides) but that has not worked.
(2) I even took out all the screws on the bottom of the laptop and slightly cracked open the part of the computer than contains the two USB ports so I could try to fix the problem from inside the laptop. That also did not work since I couldn't reach the internal chamber that holds the USB ports.
(3) I also tried using tools to dislodge the flash drive. That did not work either.
And help or tips to offer?

After I went through the Apple Support Community, I tried the easiest and simplest suggestion first: restart my MacBook. Well I did it and the USB port seems to be working again and it reads my pendrive. Hope it will stay that way and never go wrong again. I really don't like going to Apple store because none is nearby.
Thanks for the reply by the way.

Is it possible for an external device to burn out the USB port?

I think the available current of the USB port is 500 mA. If a USB device can work with a current of 500mA ~ 600mA, is it possible for it to burn out the USB port with 600mA current (larger than the safe 500mA) when connected? Or the port can never provide a current larger than 500mA?
Thank you.
P.S. The USB device I worry about is a pair of USB warm slipper (to be worn on feet in cold winter). Its label reads "5V / 2.5W", which should be safe. But I once connected it and a mouse to a USB hub, then to a single MBP USB port, and the mouse stopped working in a few seconds, and came back normal only after I switched it to another port. Now the slipper is connected to a port by itself, but I am just afraid that the USB slipper can go malfunctioning all of a sudden and drain a lot of current to burn the USB port.

...But I once connected it and a mouse to a USB hub, then to a single MBP USB port, and the mouse stopped working in a few seconds, and came back normal only after I switched it to another port....
Likely the hub is only barely able to handle the 500mA requirement. Many powered USB hubs have "cheap" power adapters and can't handle any high surge situations. Many devices like heating elements and motors have "surge currents" where the initial powering on of the device has a much larger current flow than during normal usage. Think of it like riding a bicycle. You have to push hard on the pedals to start off, but it's easier to pedal after the bike is moving.
...Now the slipper is connected to a port by itself...
If you mean the device is plugged into the Mac's USB port, then you should know that all Macs for the past few years provide more than the 500mA minimum for USB. Some other computers also provide higher power. But most USB hubs I've seen were limited to 500mA.
If you are plugged into the hub, not the Mac, then the power adapter for your hub may be barely adequate or possibly even defective.
...but I am just afraid that the USB slipper can go malfunctioning all of a sudden and drain a lot of current to burn the USB port.
IMHO, I would stop using the heater with any computer USB port. There is always the possibility that eventually something could short out in the heating element and cause a catestrophic surge through the USB port. The electronics in computers are quite delicate and I'd be paranoid about the device damaging my computer. (BTW, I have an electrical engineering background so I'm paranoid about power issues all the time anyway. ) Even if the heater is plugged into a hub, the surge current could damage the other devices plugged into the hub. While not as catastrophic as a dead computer, I'd still be irked to have to replace my mouse, digital camera, printer, webcam, etc.
Instead, I recommend plugging the heater into it's own "power adapter." One of those that give a USB port to charge a cellphone or whatever. Plug the power adapter into a power strip. Place the power strip in the floor next to the slippers. That way you can conviniently turn the strip on and off with your toes as you're putting on your slippers.

T500 USB Ports - Hardware Breaking??

Anyone one else run into this? The rear two USB ports on my T500 have failed on me. By failed, I mean the plastic tab on the inside of the port (supporting the 4 contacts) have broken off. This computer is not abused. I used the ports frequently, but never had a case where they were stressed (dropped, sat on, etc.) One tab broke off at about 14 months and the other broke off a few months later. I had a guy at a repair shop look at them. He had never seen these broken on ANY computer in his experience. Am I cursed, or has anyone else run into this?
To top it off, the last USB port has gone fickle on me. It is randomly shutting off. A restart takes care of the problem - temporarily. I am at the point of ordering a USB expansion card as ALL my usb ports seem to have failed.
Sooo tired of fixing this computer...

It happens very often to T400/500 and R500-Series. There are a lot of threads concerning this problem in this and other forums

Underpowered USB ports on new MBP with retina display?

I just recently bought a MBP as described in the title and ran into an issue that I has not been yet reported with the USB ports. Basically both USB ports seem to have power issues and frequently shut down with mention of a device drawing too much current. The ports are unable to support my HP lapdesk (a fan/speaker combination) and cannot charge my 3GS iphone and use it to tether at the same time. Both devices that do this work just fine on my wifes 2011 3" MBP and my old 2010 15" MBP (actually both of those can support a mouse, headphones, an i phone and a fan/speakers in the same USB port without extra power). Is this a known issue or do I need to talk to apple about a hardware issue specific to my laptop?

No. This is not normal.

USB Ports work Intermittantly on Pavilion Notebook

I have a HP Pavilion dv7-2270us Entertainment Notebook PC that is running Windows 7. The USB ports seem to work intermittantly. There are two regular USB ports on the left hand side and one on the right. I have an iPhone, Adidas miCoach, and wireless mouse that I usually have plugged in, and lately nothing is recognized.
Sometimes I get an error that the USB device is not recognized, sometimes I get nothing at all as though the ports aren't even there.
I have tried taking out the battery, replacing and rebooting. I have also tried uninstalling the USB Root Hub, and then the Root Hub plus controllers. When I did this it seemed like it worked - I plugged my mouse in and it worked! I plugged my iPhone in and now nothing works again.
I have Norton 360 Installed (in case that is an issue), and I also have some old Sony Ericksson software that I've recently uninstalled because someone told me that it wreaked havoc on their machine in terms of their device drivers.
The laptop is just out of warranty (Dec 2010) so this is a relatively new machine. But I love all my gadgets and need to be able to use them all!

Right Click on all devices which are recognized as unknown and Choose Uninstall one by one.
Please ensure you also do this for any and every item under Universal serial bus controllers as well. After this restart your computer and you should be good to go.
