Are the two USB3 ports on a Mac Book Pro independent channels of USB?

Are the two USB3 ports on a 15" 2012 Mac Book Pro independent channels of USB? If I plug a USB2 device into one of the ports, does it slow the other as well?
Thanks

Thanks - according to this Apple KB article:
http://support.apple.com/kb/ht5172
plugging in a USB 2 device into the USB3 daisy chain slows all devices on that chain to USB2 speed.
What I am trying to find out is if the two ports on the side of the MacBook Pro are independent channels of USB, so that you could operate with a USB2 device on one port and still obtain USB 3 speeds (with USB3 only devices plugged in) on the second port.

when did this start happening? Do it charge when plugged into an electrical outlet?

Can I get my mac book pro to connect via usb to epson ex5200

can I get my mac book pro to connect via usb to epson ex5200?

Maybe, but if the Mac has Thunderbolt ports, it will probably give you much better results with a TB to HDMI cable such as this: http://www.amazon.com/gp/product/B004CADYDO
No software, truly a plug and play proposition.

How do I Install Windows 7 on Mac Book Pro via a Bootable USB Drive

Hi Guys,
I have a Mac Book Pro 13 inch, Early 2011 Processor 2.3 GHz Intel Core i5 (I initially had OS 10.5.8 which I upgraded to OSX 10.9.4 a few months ago).
When purchased it, I installed Windows via Super Drive (that being the only time i ever used the super drive). My Windows got corrupted for some reason 2 months ago. Hence, I removed the windows via Bootcamp to perform a fresh install. I discovered my Super Drive was no longer working.
Thereon I have been trying to install Windows via a bootable USB Drive but am failing to do so. After going through several forums, I have reached the following stage.
1. Created Bootable Windows USB Drive using Windows USB (http://www.wikihow.com/Create-a-Bootable-Windows-7-or-Vista-USB-Drive). Have used this USB drive to install windows on a DELL Computer
2. Bootcamp wasnt creating a partition for windows since no Windows Installation disc was being detected in super drive. (Solved it by downloading Toast Titanium and loading the .iso file on a virtual drive).
3. Boot menu was initially not detecting external drive, so installed rEFIt - An EFI Boot Menu and Toolkit. Now it is detecting the USB Drive.
Now when I boot from this device, it get a black screen with the message "No bootable device - Insert Boot Disk"
Request someone to please help me install windows as some softwares which I work with are windows based.

So my understanding is that my Boot Camp Assistant (BCA), since it does not allow USB installer, it sets NVRAM to boot from Optical Drive. Right?
Yes.
So can I change it or update it to another BCA version which supports the same??
All BCA versions drive the logic based on the Mac Model Identifier. Unfortunately there is no real workaround. .

Mac book pro don't recognize usb 3.0 devices after installing ntfs-3g

I have installed OS X Mavericks after deleting everything in the hard drive (i.e. complete new installation). It should work fine, nevertheless the problem persist, in my case my mac book pro doesn't recognize a nexus 4 conected to the USB port, but before installing the ntfs-3g software the mac book recgnized that device. So I don't know how to resolve this problem because it hadn't solved even doing a completely new installation of the OS X Mavericks.

I had a similar problem that arose because Apple over-rode the original USB drivers with a kernal extension.
UNloading the extension fixed my problems. Perhaps it will help you.
In a terminal, type this:
sudo kextunload -b com.apple.driver.AppleUSBFTDI
If it solves your problem, keep in mind you'll have to do it after every reboot (a good use for command line history.)
If it doesn't, you can put it right back with this:
sudo kextload -b com.apple.driver.AppleUSBFTDI
Hope that helps. I should also warn you that in my experience, 10.9.3's USB performance is terrible.

My mac book pro wont boot up

i turned my mac book pro off, and now it wont boot. i try reinstalling os but it wont let me.its showing it in the disk utilty,now it wont let me install.it says mac os x cannout startup from this disk.What do i do?

I can't help you until you answer the questions I asked. If you want to reinstall Snow Leopard then follow these instructions:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Mac book pro wont run apple hardware test

Hi,
I have several problems with my Mac book Pro. Problems started so that I couldn't sign in to my account, three other account worked quite normally. I did run disk utility to fix problems that there was. That didn´t fix account problem. Then I tried to install SnowLeopard again, but it hangs after a while.
Hardware test programs starts and immediatelly after that computer shuts power off.
Here is the problem from installer.log (at least I think that here is the problem) But I can not say, what causes the problem

I wonder if it a permission issue?
Maybe chmod 777 the correct files would help
Not sure which files but you did have an error which says it cant write due to being read on. Are you the admin of the laptop and are able to mod all the files?
I could be wrong but just an idea.
Have you also tried to re-download the OS you are trying to install in case it is corrupt?

Mac book pro wont load.

Hi,
I've been having this problem for the past few days with my mac it started to run slow and then freezing at times. This is kind of an on going problem when I have to shut it down, it takes ages to load up to 2 hours. This is with me turning it off and on but last night it stopped loading it goes past the grey screen with the apple and on to a blue screen which it stays on the tone of the blue will change and the cursor will appear on it every now and again but it will disappear and come back on after a while. os x disk that came with it. This is in the disk drive but I cant seem to get it to work or eject I don't know what I'm doing with macs as I am still very new to it.
any suggestions?
The mac is a mac book pro running 10.5.8 leopard.

Hi John,
I'm not sure I understand all of your post. Based on what I think you're saying, it sounds like a dying HD. Shut down your MBP (hold down the power button for 5-10 seconds if it won't shut down). If the install disc is already in your optical drive (sounds like it), then hold down the c key and press the power button while continuing to hold down the c key until you see “Preparing Installation”)>at first screen select the language and click Continue> click on the Utilities Menu in the menu bar>open Disk Utility>select your HD in the panel on the left side>click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility such as DiskWarrior or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD (repair utilities can only repair the directory structure, not the HD itself).

Mac Book Pro wont shut

The clasp that keeps my mac book pro closed when I'm not using it has suddenly stopped working. I can't get it to stay shut now. Does anybody know what causes this and whether it is covered by the one year warranty or if it can be fixed simply?
Thanks for your time.

how long have you had the notebook?
i had the problem with the left clasp not coming down, but this was on delivery. Having only one clasp will eventually lead to the lid becoming bowed over time. I would get it seen to asap. not sure if its covered, it should be tho as its a manufacturing defect, and don't let them tell you otherwise. One clasp will lead to bowing. see picture enclosed:
