High Speed USB ???

I have a Mac Book Pro 2.16GHz model that I got about a year ago. All I need to find out is WHAT USB port is the high speed port?
As you sit in front of the laptop as normal would it be the port on the right or left?
Thank you.

I believe they are all the same speed. One of the high speed buses is used by your iSight camera. The other, I am going to assume is for use with the express slot. If you want to get serious speed I would try firewire. The firewire 800 would be your fastest option, but firewire 400 isn't really that much slower.

High speed usb port?

I have a older laptop. 5 or 6 years old.
When I plug my ipod into the usb port a message pops up saying that this devise could preform faster, if I had a high speed usb port on my computer.
Could this be the problem why I cant put songs from itunes onto the ipod?
I get this message "The ipod "its name here" cannot be synced. The disk could not be read from or written to.

You have a different problem. The iPod can work with the slower USB1 ports but data transfer is painfully slow. It seems that your iPod needs to be restored back to factory settings.

Do you need a high speed USB drive to effectively use a 5G ipod

My new 5G is working on my newer dell comp with the high speed, but not working on my older vaio without a high speed drive. Thoughts?

My new 5G is working on my newer dell comp with the high speed, but not working on my older vaio without a high speed drive
Do you mean a high speed (USB 2.0) port?
Your hard drive is not USB and it is fast enough.

No high-speed USB ports?

When my I-Pod Shuffle is plugged into either of the two USB ports in the back of my computer's modem, my computer states that there is a "High Speed USB Device attached to a non high-speed hub" and that "There are no high-speed USB host controllers installed on this computer". So I take it I'm going to have to buy some sort of high-speed USB device to fit the I-Pod, but I have no earthly idea where I would buy one!

No - you dont need a high speed port it will work fine with a 1.1 (low speed) port. It will just take a lot longer to load songs on your shuffle.
As long as it charges (high powered port is needed - you can have high powered port which is low speed) you shoud be OK.
If you dont like the transfer speed you can probably take out the USB card that you have and replace it with a 2.0 card - a fairly easy and relatively cheap procedure, but if you dont feel comforatble doing it ask a freind who is a bit more tech savvy.

High Speed USB Ports

Every time I plug my iTouch into my PC, I get a notice that I should use a high speed USB. Yet, there are only three USB ports on the laptop and all of them trigger the same alert. What am I missing? Are the high speed USB ports attached to the Docking Station?

What kind of Thinkpad do you got (for example T61, Type/model: 4236-3EG) and what OS do you use?
Did you always have this problem or something that started recently? Did you also try other USB devices that give the same error?

Must I have a high speed USB port?

Every time i connect my brand new 60 gig ipod to my computer a bubble pops up saying "A high speed device is plugged into a non-high speed USB port" Ive seen this before with other devices and its never been a problem, however with this ipod plugged in my computer freezes up, i can still click stuff and all but nothing happens, and then when i disconnect the ipod everything pops up and its like it was never frozen....very wierd, like the screen freezes when the ipod is plugged in. Anyone have any advice for me?

No, you do not have to have a high speed usb port to use the pod or iTunes. It really does make it much faster though, but it is not necessary.
I get the same bubble at home where I have the older 1.1 usb ports. It takes about 3 to 4 minutes to read my Pod and associate it with my PC. This happens everytime. The more you put on it, the longer it is going to take.
On my new laptop which has 2.0, it takes 25 seconds to register everything. That's 3500 pics and 16 gigs of music; Hence you can see why 2.0 is on my christmas list for the desktop lol.
Try giving it at least 5 minutes to fully register. The first time you do it, it always takes a long time. Also do you have any other USB things hooked up that may be conflicting with the pod?

"This High-Speed USB device is connected a non High-Speed USB Hub" pops up!

Hi. I have an iPod mini and a Window XP desktop. I've checked my computer as stated in the forum. I know I have a USB 2.0 port according to one of the posts I've read, but I guess it's not a high speed LOL. So I was wondering if it takes more time to fully recharge the iPod mini with a non High-Speed USB Hub than it does with the High-Speed USB Hub.

Location of high speed USB port on Envy 17D

I'm sure this is a dumb question and the answer must be very obvious to everyone but me, but which of the USB ports on my HP is the high speed (3.0) port? If someone can direct me to a 'photo' or 'diagram' or just tell me whether it is on the left or right and the front or back one, I'd sure appreciate it.
Thank you!

Hi,
The manual is very old, I can not find a new one.
http://h10032.www1.hp.com/ctg/Manual/c02160120.pdf
But based on this, it has 3 USB3 ports and ONLY one USB2 port therefore it's much easy to find out. 75% chance you will get the right ports.
Regards.

IPod high speed USB

Everytime I have plugged in my iPod to my computer, a little message comes up that says "high speed device plugged into a non high speed port". The iPod still functions, but it takes longer to load and stuff. Has anyone else had this problem? Is there a way to update my usb port to high speed? I have a pretty new computer, about one and a half years old.

This means that you are connecting your iPod to a USB 1.1 port. It's not a problem at all... just indicating to you that your iPod is not going to perform as fast as it could, because you don't have it connected to a USB 2.0 port.
There's no way to upgrade a USB 1.1 port to USB 2.0.
If your computer doesn't have USB 2.0 ports, then your only options are to buy a new computer with USB 2.0 ports... or find a USB 2.0 PCMCIA adapter that will work with your computer and the iPod. There are a handful of them out there, I just don't remember which ones.

Receiving 'low speed usb 1.1' error when syncing

I updated itunes to 10.0.1 a day after it was released and have synced my ipod a few times without any problems. A few days ago, an error message popped up when I connected my ipod saying that my ipod was connected to a "low-speed usb 1.1 port" and says I should "connect to a high-speed usb 2.0 port if one is available on my computer". The sync seemed to be slower than usual. My mac mini only has usb 2.0 ports and was connected directly into the computer and not to a usb hub.
I have reset my ipod, restored it, and restarted my computer and still receive the same error message.
Has anyone received a similar message and have any suggestions on what I can try next? Any information would be greatly appreciated. Thanks.

If you have tried every relevant suggestion from How to Troubleshoot iSight but your camera is still not recognized anywhere in your System Profiler's USB Device Tree, you likely have a hardware problem.
Properly applying the Combo version of the latest update for your Mac OS can sometimes correct software problems, but, if your trouble is caused by a hardware problem, there are no user serviceable parts of the camera. For hardware help, contact Apple or an Apple-Authorized Service Provider for service on your MacBook Air.

USB 2.0 high speed card won't run Canon MP800 printer

I have a Power Mac G4 AGP graphics. I installed OS X 10.4.4 on it. I purchased a new Canon PIXMA MP800 multi-function- printer. It needed a USB 2.0 high-speed connection. I purchased an Allegro USB 2.0 high-speed adapter card and installed it in my empty PCI slot. Here's my problem: When I connected the Canon printer, it would not print or scan.....it just went through the motion of sending, but not completing the task. I called Canon to trouble shoot the problem. I connected the Canon printer to my native USB 1.1 port and it worked fine. I then, removed my PCI card and reinstalled it, to be sure that it was seated correctly in. The Canon still would not work. So I plugged my old HP 1200C printer(USB 1.1) into the USB 2.0 port and my printer did work, but at the USB 1.1 speed. I contacted Sonnet Technology on the Allegro USB 2.0 PCI card and they said to try a utility called Cocktail or Tiger Cleaner to try and fix the problem. I downloaded Coctail and ran it to see if this would work. It didn't fix my problem. Any suggestions?

what type of USB 2.0 PCI card did you put in? have a look at the card and find out what chip is on it and let me know. I put one in mine that has the VIA VT6212L chip in it and it doesn't work either, despite OS X having native drivers for USB 2.0 cards.
The USB ports on my card didn't work at all until I installed a driver that I got from VIA. Even then though only 1.1 devices work while the 2.0 devices are not even recognised.
From what I hear, adaptec brand USB 2.0 PCI cards are what you want to get in future, plug them in and off they go (wish I'd done my homework). No messing around with drivers that support only half your new hardwares features.......of course its the other half that you actually need.
I've spent hours reading through all sorts of info and scanning forums everywhere to try to find a fix, I understand why you're a little woozie. A possible fix that people seem to keep suggesting is to zap your PRAM (restart holding command-option-P-R keys, don't release the keys until after the 3rd chime), didn't help me and I doubt it'll help you but at least when people tell you to try it you can say you've done it.
here's my post to my problem:

What is the difference between USB bus and USB high-speed bus?

anything that i plug into the USB ports that registers in the USB high-speed bus does not show up on the desktop. i have tried different devices and none work when the system profiler show them in the high-speed bus. anything i plug into the USB that registers in USB bus works just fine. what is going on here?

I've got a couple of SanDisk memory card readers. Nothing shows up on the desktop until a formatted card is inserted in the reader. If it's not formatted, I believe it can be formatted in Disk Utility.

Cannot program USB-8452 into I2C High Speed Mode 3.33MHz

Hi, I am using the USB-8452 as I2C high speed host (1.11MHz ~ 3.33MHz) to access slave IC. But I cannot program the host into 3.33MHz with "NI USB-854x I2C Configuration" in the driver. The max speed only reach 1MHz (Fast Mode Plus) thru scope observation. Please tell me what's wrong in my program? Thanks in advance.

Hi,
Do you currently use the NI-845x driver version later than 2.1?
Please check the following message.
http://www.ni.com/pdf/manuals/373865a.pdf
The NI USB-8452 in this kit has been updated to a firmware version that is
incompatible with NI-845x driver versions prior to 2.1. If an NI-845x driver
version prior to 2.1 is installed on your system, you need to upgrade your
driver by using the enclosed installation CD or downloading the latest
NI-845x driver from ni.com/downloads.
If you cannot upgrade the NI-845x driver on your system, you can refer to
an online document for additional options. Visit ni.com/info and enter

Why does error 200279 occur at high speeds only?

I am using a VI very much like the one attached here, and as my motor speeds up and the period value decreases, the vi fails, and error 200279 shows up as displayed in the attached 2 jpg images. This VI is reading the period value of an encoder by rising edges. The error does not show up at low speeds, only high speeds. Hardware is wired through USB ports on PC. Using Labview 2012 and Windows 7.
Do I need to specify the samples per channel for the READ in the case structure to eliminate this error? The error only occurs when the period gets quite short, e.g. 9ms or so. At higher period values (slower motor speeds) the error does not appear. I am using the counters built into the cDAQ9174 chassis and the NI 9401 module to read the period values of my encoder. What is happening at high speeds to cause this error? I thought that the setting on the DAQ Timing VI required that 16 periods are read every iteration, so, why is it saying that it is trying to read samples that are no longer available?
Also, is the "Append Array" building up a large array that is being carried in the SHIFT REGISTER and causing things to slow down? There are a huge number of periods occuring with an encoder at 120 ticks/revolution. should I try to keep this array truncated or something to reduce the size of the data being handled for each iteration? Can this large array be causing the 200279 error?
Thanks,
Dave

I think there's a combination of things that could be contributing. I don't have time for a full explanation right now, here's some quick mods I did to the code you posted. Essential changes are:
- made separate loop for collecting data into a big array. (Maybe you can consider dumping to file instead of growing an array in memory?)
- used a queue to transfer data between loops
- increased the buffer size dramatically while still calculating average of only the most recent periods
- reduced the acquisition loop rate -- expect to retrieve more data points per iteration
There are a couple other things I'd probably add or change with more time, but this minimal set of mods should help some.
