USB Ports and Bus Information

Hello, I have an i7 MBP 17" and am curious as to whether the 3 USB ports all share the same Bus, and if not, how they break down.
I have a USB reader that requires 2 USB ports (one for power, one for data). When I attempt to transfer data (usually in excess of 16GB) to a USB drive the whole works eventually chokes up and it can take up to 45 minutes to move 16GB. Firewire 800 only takes 12min at worst.
So, is there a way to connect these USB devices to improve throughput?

The difference between 12 minutes and 45 minutes is pretty nearly what one should expect for a large transfer via FireWire 800 vs USB 2. In real life, FW800 is more than twice as fast as USB 2, and it creates much less CPU overhead. If your memory cards and/or your reader can't move data at the full speed of USB 2 (and many can't), that slows things down more.

Did you ever get this resolved? I am having the same problem and have tried just about everything for my dv9000.

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV?

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV? I have a MiniDisplay Port to VGA adapter, but there are two issues with it: The new display doesn't have a VGA port, and even if it did, I wouldn't want to have my mac constantly attached to the display by a cable. I was looking for a way to use the TV as a display without any wires. Is there some type of bluetooth setup I could use? Please let me know if you have any suggestions.

As I wrote above, I think you should look into the Apple TV yourself. The best place to find information about what it can and can't do and to ask your own specific questions is probably in the Apple TV forum, here:

Lost the keyboard backlight, use of my USB ports and camera shows as disconnected. How do I fix this?

Please help. I'm still a MAC rookie.
I unplugged my Pedometer from one of the USB ports on my Macbook Pro. Ever since then, I lost the backlight to my keyboard. I did some troubleshooting on these discussion boards and found a few with similar issues, but most of the discussions were old and the solutions were out of date. As one of them advised, I checked to see if my Isight Camera was still connected and it wasn't. I also tried plugging a few different things into both USB ports and neither of them worked either. So whatever caused this, it's affecting all 3 of these things. I don't know if my Pedometer is old/bad and it "short-circuited" the USB port and everything else along with it when I unplugged it or if something coincidentally went bad at the same time that I removed it.
I read some old answers from the discussion boards where they suggested a Command (R) system recovery reboot. But I also read that that really doesn't help on newer operating systems. I am on OS X. Here is my Hardware Overview:
Model Name:          MacBook Pro

Processor Name:          Intel Core 2 Duo

I did recently purchase a backup drive and I THINK I previously backed everything up properly. But, I can't even plug that into the USB port now to see if I
can somehow use that to fix this since the ports aren't working. I have no idea what to do. Does anyone have any suggestions? Please!?
Thanks in advance!

Issue with USB ports and Blue Screen

So, I had to send my Satellite L355-S7905 back and Toshiba had to do a factory restore. I got it back 2 weeks ago and now I have a new problem; 2-3 times a day my mouse and printer stops working, these are connected via USB ports and I get a message that the device is no longer recognized. I found a solution on the Microsoft site to go to Device manager and Scan for new hardware changes and then Restart. I do this and when I restart I get the dreaded blue screen. So I then have to unplug, take out the battery and turn the computer back on. Then the mouse and printer are recognized. This will work for several hours and then the whole thing happens again. So, are there any long term solutions? Can anyone tell my why this is happening? Please note, that that the printer and mouse are not new and no new hardware has been installed since getting it back from the factory.
Thank you for your help!!
Jennifer

start-->control panel-->system and security-->device manager-->expand the universal serial bus controllers-->right click and uninstall all of the USB root hubs-->restart-->they will reinstall on restart, and search for attached hardware.

The apple tech on the phone, went to my control,panel
Went to my devices. Original iPad showed up,there In red and then he had me go,to apple website, download something and it said it could configure to my computer.
Is,finally answer,to me was go to the apple care,one on one appointment, and it's my "software"
A man I know told me "Apple at store, won't be able to do,anything for me"
That's not very positive.
What else? Can't I download iPad drivers,into my computer?

Hy won't my ipod touch 5G connect to my computer or itunes? I've tried new USB cables, different USB ports and uninstalling itunes and reinstalling.

Why won't my ipod touch 5G connect to my computer or itunes? I've tried new USB cables, different USB ports and uninstalling itunes and reinstalling.

See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:

paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause

So I stuck a key into one of the USB ports and then a message came up and it crashed straight away and now it won't turn back on.(the message was to do with the USB port taking to much power when there wasn't anything besides the key) help?

Please help! My mac is about 6 months old and I was just playing with my keys and stuck it in the USB port and then it crashed and won't turn on, it's not picking up the charger (the little led light isn't on) and pressing the power button does absolutely nothing

Don't be so surprised, people have stuck worse things in worse places before and it was on purpose

Reset the SMC first. If this doesn't work, reset PRAM. Move down troubleshoot with links below. First, SMC reset for MBP models 2009 and later:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

No, and that shouldn't be done with an AirPort Extreme or Time Capsule.

Updated OS X Mavericks and now USB ports and MS Office apps won't work. How do I fix this?

I updated my MacBook Pro (mid 2012) to OS X Mavericks 10.9.4 and now my USB ports and MS Office apps won't work. What do I do to fix this?

What system version were you running before you updated to 10.9.4? Another 10.9.x or something earlier?
What version of Office? 2004, 2008, or 2011?
Were you aware that Office 2004 does not run on recent versions of the system?
When you say your USB ports do not work, on what are you determining that?
Were you aware that Mavericks does not display external disk volumes by default?

After downloading itunes, I hooked my iphone up to my computer and told it to restore. Got an error message, 1015, and it wouldn't restore my phone so now all I get on the screen is a pic of a usb port and an image of itunes. Anyone know what I can do??

can anyone tell me how to restore my iphone? Itunes will not let me and now my screen just has a usb port and itunes on it?

Error 1015: This error is caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple.
What this means is you have to delete your .ipsw file (it may be corrupted or old) and attempt to restore your iPhone again.
Where the .ipsw file is found:
Mac                         - ~/Library/iTunes/iPhone Software Updates
Windows XP           - C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Updates

HT204384 USB Port and SD card port not working

My USB ports and my SD card port do not work. They have both worked previously, but now do not read anything on my new Mac Book Pro.

If you are still under warrantee, take advantage of it and go to the Apple store.

I have just recently lost use of 2 USB ports and my isight camera. I have an isight G5 imac that has been working great. I have rebooted, reloaded my OS, and tried PRAM reset. I can use my keyboard, but not other peripherals. Any ideas on diagnostics?

I have just recently lost use of 2 USB ports and my isight camera. My keyboard works fine, but there is not any indication of connections when probing USB in "About this MAC". I have rebooted, executed a PRAM reset, and reloaded my OS, but to no avail I am out 2 of my 3 USB ports. I don't know how to diagnose the issue. Any ideas?

Well, if you've tried different USB cords and devices and have reset your PRAM:

And SMC:

I'd say your USB ports are shot - since they are an integral part of the logic board, replacing it will most likely be expensive. I'd still go for a definitive diagnosis at the Genius Bar.
