USB speed help!

I have a macbook pro from late 2009. It has a 1.1 usb speed but I need a 2.0. Is there anyway to install an upgrade or get a plug-in host to get the 2.0 speed from my usb drive?

A Macbook Pro from 2009 should have full USB 2 support. USB 2 has been around since the early 2000s. I would think Apple is not that far behind the curve. And cetainly not with Lion 10.7.3 installed.
Something else is wrong. Like you have a USB 1.1 hub connected and your external is going through that.
The port you are using is bad.
The cable you are using is bad or very inferior and can not do USB 2.

USB Speed

First off, I am disappointed that the new iPod I have been waiting for (video and photo and music) no longer supports FIREWIRE. I use a lot of firewire disks, audio interface, and have a nice hub... but if I decide to obtain a new iPod I now have to examine my USB speed.
When you use the profiler tool and look at the USB tree on my 1.25GHz G4 iMac, you see three separate USB devices - two are 12 MBs and one iw 480 MBs - The keyboard and printer are on the slower ports, and I have a SanDisk reader apparently on the faster port.
Is that the case that not all of the USB connections are high-speed USB? Should I be expecting that at least one USB connection on this computer will be a high speed USB?
Thanks

All three of the USB ports on your computer are USB 2.0; the keyboard as well as any USB devices plugged in to the keyboard will operate at USB 1.1 speed. The printer may also operate at USB 1.1 speeds.

USB speeds on late 2012 model Macbook Pro

I recently bought a new Macbook Pro (without retina display) to replace the 15" MBP I bought in 2006. The USB speeds are extremely slow. For example, I transferred a 650 MB file from the new MBP to a thumb drive. It took more than 45 minutes. When I then transferred to my 2006 MBP it took less than 4 minutes. Both are running Lion. What gives? Is there a configuration issue or is there a problem with my USB ports in my machine?

Wrong USB Speed

Hi there,
I have E-MU 0202 and when I click on the [Control Panel] icon on the bottom right the "configuration center" appears. I can select the device, sample rate but that's not the point. It is written there "USB Speed : 1.1" while it should be 2.0, right? What should I do to change it?
Now I have Windows 7 but I don't remember how it was working on Vista or XP. Simply I didn't noticed that before, I think.
Thanks for some answer!

Since you have switched from XP/Vista to W7, could it be possible that you need to install some "drivers" to get USB 2.0 mode available (drivers are bundled with motherboard or you can check from the support site for your motherboard)?
Also, is there an option for USB 2.0 support in system BIOS.

Echo heard by others in VOIP application with USB Extigy HELP!

>Echo heard by others in VOIP application with USB Extigy HELP!x I have a soundblaster Extigy... the external USB model. It has been working fine for me but I just discovered a problem when I tried to use it during a Video/VOIP application.
I can get the other party up in the video session and I can hear them perfectly. They can hear me perfectly. The problem comes in when they speak.
When the other party talks they hear a huge eo on their end. I don't have an echo when I speak or listen.
We tried various things. When I disconnect my mic from my soundblaster and use the mic on my camera the other party does not have an echo when THEY speak any longer.
What is even more strange is that if I open Skype and engage in a skype conversation the person in the OTHER VOIP/VIDEO application can not only hear what is going on in that one, BUT when they speak the person in my skype conversation hears it! This is when the other party does not even have skype.
There is something definately going on with my soundblaster that is causing the other party to have an echo on THEIR end.
Any help would be greatly approeciated.
BTW... I'm running windows XP Pro.

A Thanks for the help, we'll try that. We are using a D-LinkDGL-400 Router with th D-LinkModel DGS-2208 switch. The program we are trying to run is OpenMeetings (an open source application) that we are hoping to get up and running so non-profit organizations have a free place to collaborate (http://www.caihq.org:5080/openmeetings/
What makes this strange is that when I use the Creative Orbit Camera I have with the built-in Mic not running through the Extigy there is no echo but the background noise is a bit of a hassle.
I'll try all you said and post the results.
Thanks again for the help.

Bios is all up to date, drivers for modem and scanner all up to date - any ideas why the USB keeps cutting out?
The real drag is the only way to get USB back is to reboot. Any help gratefully received.

Rock Ape (UK) ) Thanks in advance.

gilgaron is correct. power the hub and place the devices that require over 500ma on it-if the hub supports high power-which it should. look at your periphs you will notice that they have the power requirement listed on the sticker.
each individual root hubs only powers 500ma for all the ports not 500ma for each individual port. so the best bet usually is get a self powered hub and place the 500ma+ devices on it. also you may have the option of self powered device instead of usb power. that is also suggested if they need 500ma or more.

HomeHub 3 - USB speeds painfully slow - known issu...

Hello I have a BT HomeHub 3 - FW version 12 - on Infinity Option 2.
I have recently bought a WD 2TB external drive and connected it to the USB port on the homehub in the hopes to have all my media on it to share across the network.
It attached fine, was detected fine, and I've successfully mapped it as a network drive on my PC without a problem.
The drive is formatted in NTFS, and my PC is connected to the homehub via the gigabit port.
The read and write speeds though are painfully slow - pretty much solid at 2.0MB/s. Is this just "how it is" or is there a solution, because as it stands I can't see the point in there even being a USB port! I could download another version of the file 4 times faster from the internet than I could copy it locally to the HDD!!
I can't find any information about this or indeed see many complaints, so I'm wondering if this is just mine?
Any feedback would be appreciated - happy to receive technical answers.
Thanks for any help!

Keith, I have to say that your answer gives no technical insight of the situation,
I highly doubt that this device does not have the processing power to do a transfer of more than 2-3 Mb/Sec,
Don't forget there's even a gigabit ethernet port, and you can easily achieve very high speeds using lan or even the internet connection - forget that this is due to the hub being slow - no chance.
Second point you mention, SMB protocol is not that efficient, that's not the reason for slow speeds again. I can confirm I've got an SMB server setup on a Linux 5 yeard old netbook in the Lan and it's still performing faster than 2 Mb / Sec. SMB is again NOT the problem.
It's most likely a firmware issue where the USB port is either throttled down intentionally or not utilized as a proper USB 2.0 port - I think BT or whoever makes this box ought to give the community an explanation on the matter. When claiming that the usb port can be used to connect storage media they should also mention that the maximum speed is not more than 3 Mb/Sec - otherwise the statement is misleading as most people know that usb storage media perform a lot faster when connected to computers.
It's like someone telling you, that his car drives like ferrari, but not telling you that it cannot do more than 20 mph.

Clicks and popping with recording and USB interface-HELP!!!

I've submitted this twice, got some responses, but has twice been ignored into oblivion. I apologize for the reposts, but this is VERY IMPORTANT, and I've been struggling with this issue for MONTHS now dealing with countless hours of lost time trying to fix it to no avail.
I'll try to include as much detail as possible.
I use:
MacPro 2 x 2.66 Dual-Core Intel Xeon
3 GB memory
Logic Express 8.0.2
245.13 GB empty space on Hard Drive
THE PROBLEM:
When I record, I get computerized clips/pops
http://www.moogiex.com/clickpop.mp3
http://www.moogiex.com/morecackling.mp3
I record via a PreSonus Audiobox USB. This problem did NOT start when I got the AudioBox, but several months after.
When I simply monitor the sound going through the box, the sound is fine.It's something between the Box, and the computer output. My guess is some incompatibility with Logic Express or Core Audio and the AudioBox.
It is NOT the microphone or the cable (the pops occur with anything going in, 1/4", XLR, different inputs).
The clicks START with Logic Express. If there are any recording program open when Logic Express is open, and I record, I get the SAME pops.
It did this both under 10.5.6, 10.5.7, and now 10.5.8.
It is NOT clipping.
When I'm recording with LE:
—There's 1.27 GB of FREE Memory while I'm recording.
—Logic Express is only using 6.7% of CPU while recording (of only one of the four processors), and about 90-95% of CPU space is free on all four processors.
—This happens on ANY audio input, and it doesn't matter how many other tracks, how long it is. I just started a brand new file and it does it.
—This happens when I use ANY input into my computer, but is STARTED by LE.
Here are my Logic Preferences
Core Audio- ENABLED
System Memory Requirement 66.0 MB
Device: AudioBox USB
I/O Buffer Size: 1024
I/O Safety Buffer- UNchecked
Recording Delay: 0 samples
Universal Track Mode- CHECKED
24 Bit Recording- CHECKED
Software Monitoring- CHECKED
Independent Monitoring Level- Checked
Process Buffer Range: Large
ReWire Behavior: Live Mode (Higher CPU Load)
Maximum Scrub Speed: Normal
Scrub Response: Normal
There is *no* driver with PreSonus' AudioBox. It is simply "compatible." Here's what System Profiler says:
AudioBox USB (plugged into my Mac Pro's front bottom port):
Product ID: 0x0301
Vendor ID: 0x194f
Version: 1.08
Speed: Up to 12 Mb/sec
Manufacturer: PreSonus Audio
Location ID: 0x00200000
Current Available (mA): 500
Current Required (mA): 500
Here's what I've tried:
—Disabling CoreAudio, shutting LE 8 off, restarting LE 8, enabling CoreAudio again. This worked ONCE. It hasn't worked since.
—Disabling CoreAudio, shutting LE 8 off, SHUTTING DOWN, RESTARTING, opening LE 8, enabling CoreAudio again. This also worked ONCE. It hasn't worked since.
—"CPU Saving Mode"
—I/O Buffer to 256, 512, and 1024 (default) (IMPORTANT?—speed of popping actually INCREASES with larger buffer?)
—I/O Safety Buffer checked and unchecked
—Changing Recording Delay samples
—Pretty much fiddling with any of the controls
—Disabling Airport does nothing (was previously working fine with Airport running)
—Quit all applications, open up QuickTime (pro) or Audacity, and record something. It records perfectly. I go back to LE and the clicks and pops are gone, but only until I use anything with effects, then the clicks and pops return. This works SOMETIMES.
—Reset the preferences, and that has worked ONCE, and then the clicks and pops came back (albeit not as prominent, but they were still there).
—I trashed all files related to Logic and reinstalled. Worked ONCE.
—Restarting does help, but only temporarily, as soon as any pull is put on Logic, the problems return.
—Using a different USB port. I thought this was the solution because the problem shortly went away with regular use of Logic, but problem came back.
—Uninstalling Logic, Reinstalling Logic Express, same deal.
PLEASE, PLEASE, PLEASE HELP. I have a lot of money sunk into all this equipment that's practically useless with this recording issue.

Man, I feel for you on this.
I would love to see what your pops and clicks look like in your waveform. If you can take a snapshot of it and post the pic here that might help the diagnosis.
Your audio files certainly SOUNDS like you have a clocking problem. It really sounds like your CoreAudio driver/MacPro and your USB interface are not locked up in sync - as in: which is master and which is slave? I know some interfaces include a software control panel that allows you to set the status of the interface clock to slave to the computer or to be the master. It sounds like yours doesn't come with drivers but is there any control panel for this Presonus device?
Another place to check is in Applications>Utilities>Audio Midi Setup
On the left under "Properties for <your interface>" what does it say for the clock source?
Also in this panel, to the right it should have a button for "configure device". What happens when you click it? For example in my case it automatically launches my Apogee Duet Maestro control panel. In your case it might launch something similar, although I think you mention that you never installed anything, which I find strange to begin with - that this thing should just work out of the box with no driver at all.
I've struggle with w similar problem with my Apogee Duet, although nothing of this magnitude, maybe 4 or 5 clicks per 3 minutes of audio and these turn out to always be sample drops where 5-10 samples in a row are all the same in the waveform, as if my interface and computer stopped talking for a milli second. I did find that if my Apogee Duet was chosen as the default or system output in the Audio Midi Control Panel I mentioned above then the clicking was more frequent, as if choosing the audio interface for any system output caused a conflict with choosing it for Logic. I thought this was strange but you might want to investigate that further too.
At any rate, it does sound like a digital clock syncing issue to me by the sound of your audio. What effect does changing the sample rate of the recording have on the problem?
Let me know if any of this leads to anything.

New To The Forum And Looking For Speed Help!

Hello, After trying to find information about my problem on the Internet and then speaking to the BT Indian Call Centre, I stumbled upon this forum. I am hoping, having looked at so many helpful comments and contributions, that I might be able to shed some light upon my connection speed issue. I have had a very pleasing and stable Internect connection speed of nearly 8Mb. However, I recently moved my router to the Master socket in the house which was better positioned to give a good WiFi signal throughout my house. However, when I have plugged in the router and booted it up, I can only connect at just over 4Mb regardless of what I try. I know I am at risk of sounding a touch ungrateful here because there are many more people with bigger problems than I but I would be very grateful for some advice / assisitance as to why my problem might have occurred and how I might regain my previous speed. Thank you in advance for any help! Cheers.
Solved!
Go to Solution.

welcome to the forum
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems) http://speedtester.bt.com or http://bt.custhelp.com/app/answers/detail/a_id/9354/c/346,4740,5520 and post the results .
are you connected directly to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

N95 crashes in Data transfer via USB cable, help?

I ve been using my N95 with no problems for more than a year. Sometime ago I bought a new 8Gb Micro SDHC memory card, it was recognised by the phone and worked perfectly. But after the card was stored with data for more than 1gb, the phone crashes everytime I try to copy even the smallest file on the memory card through Data transfer mode via USB cable. Than I try to copy a file an error message is displayed in Windows XP and the phone reboots. The strangest thing that I can copy without a problem even a 500 mb movie file to the phone if the stored space on the memory card is say like 985mb, but after that it will crash even with the copying a 10 kb text file.
Any help would be appreciated.

No, its not the file system or Memory card itself - cause transfering a data through a card reader works fine and the phone recognize correctly everything transfered. Can it be the case of USB cable driver? May be I need to install it or go for a newer version? BTW, I removed Nokia PC Suite from my notebook - cause I dont used it much, but this program still used a lot of my PC resources without asking to. I belive that PC Suite is not nesessary for using the phone through a Data Transfer mode?

10.6.8 Update - No USB Support - Help!

Early 2008 MBP under warranty for another 34 days. Nothing interesting installed beyond usual Mac, MS and Adobe software. Occassionally run Parallels 6, but not today and not recently.
At 9:00 was offered the auto update to 10.6.8. Closed open apps and let the MBP do its thing.
On reboot the usual screen came up but there was no trackpad or keyboard support. Was able to use a bluetooth mouse and all apps opened but still unable to type anything or use the trackpad mouse. Also noted that there was no USB support for an external drive, or keyboard (or I would have tried to roll back to 10.6.7 with Time Machine.
Rebooted multiple times with the same outcome.
Spoke to Apple and they had no suggestions except to get warranty help. Well that's 50 miles away (service provider, not an Apple store). Any suggestions to save me two trips (there and back to deliver and pick it up)?

I have a early 2008 macbookpro 2.8 duel with silver keys.
I purchaed the 10.6 disk from the apple store. I've had the machine for years and purchased it refurbished from apple.
I did the erase and install and migrated everything over from external drive, then did update to 10.6.8 and the usb ports still would stop working after a few hours.. Then I read on another apple community forus to reset pram, and pull out the power cable, take out the battery and hold power key for 5 seconds, then restart. that seemed to fix usb issue so far..
But overall my computer seems to be running slower then when using just 10.5.8 and it did not wake from sleep once and I had to force power off and restart.. But maybe its just getting used to 10.6.8. we will see..
Also, on another note, my battery is totally dead, and I can only run computer with power cable.. Will this affect things? it never did with 10.5.8..
Oh, on my erase and install, I just did the simplest version and did not do the full erase to zero using he advanced security measures.. I just did the one where it writes on top of everything..

Poor USB Speed Issues

Connecting anything to my machine via USB has become painfully slow. When connecting an iPod to the USB port on the front of the machine, a window will sometimes popup saying "You are connecting to a USB 1.1 port - connect to a 2.0 port to ....etc etc"
It IS a USB 2.0 port - Do the internal USB controllers go bad after a while? My machine has a lot of time on it and cannot think of anything else that could be the cause.
And if so, what do I replace?

Hi. The Apple Official on USB problems is here
http://docs.info.apple.com/article.html?artnum=303598
Although not mentioned there, sometimes using the FireWire reset procedure (bottom of the page here) helps USB
http://docs.info.apple.com/article.html?artnum=88338
USB on G5s has always been a bit suspect where USB power is concerned. Does it work ok plugged into the rear ports? A powered USB hub, such as

sometimes helps.
The USB is on the main logic board (as are most things), so a PCI USB card would be required if it is duff.
Good Luck.

Router Speed Help

Hi, thanks for taking a look at this.
I recently upgraded my internet, and realized that the speeds I am receiving over a wireless connection are no where near what I receive when I am directly connected to the router, or even to the modem. I currently have a Linksys Router E1500. When I connect directly to the modem, I can get about the same as when I connect to a LAN port on the router, but connecting wirelessly my speeds plummet. I have attached two photos demonstrating the wired and wireless connections. I've tested for other networks in the area and have come up with nothing, and changed the broadcasting channel a few times. Am I missing some settings I should change? Thanks for your help.

Hi, this may resolve your problem. I hope this will help.

Very Poor/Slow Broadband Speed (Help Please)

When we first went with BT we were getting speeds of 6-7mbp's now we are lucky to get 2mbp's.Ive noticed that during the day it can drop below 1mbp's.
Can someone give me some help or advice on what I can do to fix this problem.Our line has a maximum of 8mbp's and according to BT should be getting at 7mbp's.
I have posted the Hub Managers connection details below which has been connected for over 4 days and says downstream 8mbp's which is nowhere near what im getting.
