USB 3.0 port running at 2.0 speed

Yes the the the yellow marked driver is installed exactly as you have shown. But the usb device tree viewer software is indicating that the device is working as usb 2.0. Also I tried to do use the "Crystal Disk mark" to check the speeds, and the speeds were corresponding to USB 2.0. The official HP website doesnt have usb 3.0 drivers listed as it has been done for earlier OS such as Win 8 or Win 7. I have 2 hard disks, both are USB 3.0 so I dont think that there is any problem in the hard disks. HD 1 - Toshiba Canvio 1.0 TB and HD 2 - Seagate Expansion Portable 1.0 TB.

I was using win7 so far and had no issues. Recent upgrade to Win10 has caused me this problem.My laptop has 3 usb ports, 2 of which are USB2.0 and one is USB 3.0. However the USB 3.0 port is running at speeds of USB 2.0. My harddisk is seagate expansaion portable 1.0 TB. Any solutions. I have already done successful online update of all drivers.

USB port running on 1.1 speed instead of 2.0 on T42

Hi Everyone,
Is these someone who can help me to update my USB port's speed from 1.1 to 2.0? I had ungrade my Bios and Embedded Controller, but no luck. My laptop is running Windows XP Professional Service Pack 3 and your help will be highly appreciated. Thanks.

This is a common issue on T4x machines, your Southbridge chip is failing.

Right USB 2.0 port running slow - seems to be stuck in 1.1

I'm running an old MBA from 2011 (A1370) The right side USB is playing up:
it randomly ejects external HDDs and thumb drives
often it doesn't even register that something has been plugged in
drives plugged into the right port are opperating at about 1/8 speed compared to the left port.
Any ideas how to figure if it's a software or a hardware issue?

How do I speed up my USB 3.0 port

I have Windows 7 Home Premium 64 bit. I am getting messages to the effect that my mass storage device will perform faster if I configure my USB 3.0 port. How can I speed up my USB 3.0 port

The picture is not visible yet, but do you have this driver installed?
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-103655-1&cc=us&dlc=en&lc=en...
Install this driver and reboot. If that does not work try uninstalling drivers for each usb device and reboot to let the driver reinstall.

T40/iPhone Syncing: "Device can run faster if connected to USB 2.0 port."

Each time I sync my iPhone 3G with the T40 (2373-73U), a baloon message appears saying the device will run faster if connected to a USB 2.0 port. I thought it was so connected. I've reviewed the ThinkPad article entitled "Troubleshooting USB Devices" as well as the Microsoft article kb/310575, "Advanced Troubleshooting Tips for General USB Problems in Windows XP." I use Windows XP Professional with SP3. I confirm that BIOS is enabled for USB 2.0. I saw something that said IRQ 11 is being used for the USB ports. Pursuing the baloon message, I'm told to unplug the device from the current port and plug it into one connected to the enabled USB 2.0 hub, showing six such ports. But my T40 has only two places in which to plug the iPhone USB cable, and neither will eliminate the message that things will work faster if I use another port. Can any one offer a suggestion?

HP 2005pr USB 2.0 Port Replicator - Video not with my Surface Pro 3

Hi everyone,
I've spent tons of hours already trying to get the HP 2005pr USB 2.0 Port Replicator working with my Surface Pro 3 and no luck. I mean, the USB replication / hub works, meaning that if I plug in a USB mouse / keyboard, they work. It recognizes the device in Device Manager and the ViewSpan application is running. But if I plug in a display in the VGA, nothing happens, no monitor gets detected, and even if I "force-detect" one it still doesn't display anything.
I've tried with 3 driver versions so far:
0.2.5 - not working at all. Reboots my Surface while installing. (this one is on the device itself).
3.X - which is the first with support for Windows 8 I think. I can install it and everything works as described above - meaning no VGA.
5.3.X - same story as above.
I've tried uninstalling, restarting and uninstalling several times with both versions. No luck. And I've literally been on every forum where people have problems with the replicator and nothing helped.
Anyone had any luck getting such a setup to work?
Or any ideas on how to get it to work?
Thanks.

Hi @blinkk2
I see that you are having problem connecting an external monitor to your Microsoft Surface Pro 3 through the HP USB Port Replicator. As the USB ports are working with the mouse and keyboard we know what the Port Replicator itself is working this is going to be something with the drivers on the Surface. I would recommend contacting Microsoft Support to see if they can recommend a graphics driver for you.

Mac Pro USB and FW800 ports not working

I've been reading tons of forum entries in the Apple Support Community and in other forums. Nothing seems to answer quite what's going on with my Mac Pro Tower.
Here are the details and steps taken up to now:
- I'm running a Mac Pro Tower (MacPro 3,1, 2x 2,8GHz Quad Core, Early 2008 model), currently running OS 10.6.8
- I moved before the holidays in December and left my computer unplugged for over month while away. Didn't have any issues before the move.
- up until the last couple of weeks, I had actually been running on Leopard (yes, I'm a luddite!, please, no teasing )
- I was trying to update my ipod touch's iOS and kept getting errors preventing it from completing the process. At first I thought it was an ipod app causing the issue after having read a few threads on that topic...
- Also, on startup, the Mac started searching for a Bluetooth keyboard, of which I don't have, and would not detect my usb keyboard. I would disconnect and reconnect the keyboard and the majority of the time, the Mac would then recognize my USB keyboard.
- I decided to upgrade to Snow Leopard, which didn't help with the iPod update. I did not do a clean install.
- Then I noticed that my USB stick wasn't working and tried it in all the usb ports (except the ones on the keyboard)
- Also, I had removed and then reinstalled printer and scanner drivers for my All-in-one printer. After this I kept getting constant communication errors between the mac and the printer via the usb port, although I was able to print a test page.
- I've used Hardware Test once which didn't detect any issue.
- I reset the SMC
- I reset the PRAM, and for a few seconds I was able to read from my USB stick, then never again, even after another PRAM reset.
- I've cleaned the whole inside of the computer and checked for loose cables. Cables are in so tight it's so hard to loosen them!
- I now tested all the ports:
     ∞ the 2 front and 3 back USB ports are unresponsive to my usb key and to my VoyagerQ dock
     ∞ the front and back FW800 ports are unresponsive to my VoyagerQ dock
     ∞ However, the keyboard works in any fo the back ports and my USB stick is recorgnized by the USB port of the keyboard.
     ∞ I also plugged in my Logitech webcam into the keyboard and it works there but not in any other port.
     ∞ When I plug in USB powered speakers into any of the ports, they work fine
     ∞ And the FW400 ports are also working fine with my VoyagerQ dock
- a few times, including once today, my mac restarted by itself. The times before today, I thought it was because I was sort of moving back the computer in place, but today I was nowhere near the computer.
So what does this all mean? Should I do a clean install of the Mac OS? Or is it a problem with my Logic Board?
Any insight please would be helpful. I had Apple Care and missed the reminder to renew it so I really hoping not to spend more money than necessary.

Thanks Grant,
The battery is a start and something inexpensive to replace.
I did do a PRAM reset (command + option + P + R) and was able to hear the chime 4 times. I tried resetting it a number of times over the past week, as well as yesterday with no success in reviving the USB ports. But isn't it weird that my USB powered speakers work by plugging them in any USB port (with the mini jack pugged in the back or front earphone plug)?
I did not use the USB ports on the keyboard until yesterday, so that is not the cause of the other USB and FW800 ports failing. But I'll follow your suggestion and not use them except for the mouse.
Another weird thing that happened yesterday, I have 16GB of RAM and I spent all day trying to troubleshoot a RAM issue that is magically fixed after leaving the computer on overnight to do an extended Hardware Test. The issue was:
- Only 8 RAMS were being recognized
- a red LED light appeared on the top riser
- first I thought I had isolated the faulty RAM bar, and then a second one
- Then going pair by pair again, I no longer saw the LED light
- Put back all 8 bars, only 8 GB of RAM recognized
- Left computer overnight running Hardware test (said it took almost 3 hours, with no errors)
- Now all 16 GB are recognized!
Thanks again for the tips

2nd generation ipod shuffle not recognized by usb 3.0 port, 2nd generation ipod shuffle not recognized by usb 3.0 port

Hi,
My 2nd generation ipod shuffle will not connect to any usb 3.0 port. I've tried on to computers -- one Windows XP and the other Windows 7. Any ideas?

Hi
I had the same issue with my Late 2009 Mac mini running Mavericks and iTunes 12. When I connected my 2nd generation iPod shuffle it would blink amber once then do nothing. This seems to be a common problem with the iPod shuffle and newer versions of Mac OS X (10.6 and up) and iTunes albeit with somewhat varying symptoms but the same overall problem syncing the iPod with iTunes.
The predominant go-to solution is to give the iPod more power by either connecting the iPod directly to a USB port on the Mac or by disconnecting all other USB devices. On paper this makes sense.
What worked for me, however, was the opposite. After trying to solve this problem for hours (weeks, months), I had success ONLY after adding a low-powered 4-port USB hub to the chain between the iPod and the Mac. I suspect this had the effect of throttling the power supplied to the iPod from the Mac. I was able to perform a restore on the iPod then sync my music over.
I can't tell you much about the USB hub except that it is running at USB 1.1 speeds (12 Mb/sec). In theory a USB 1.1 extension cable should also do the trick. You might even be able to use the USB hub in old wired Apple USB keyboard. I will attach a photo of the hub I used to this post for greater clarity.
I really hope this helps.

USB 2.0 port no longer recognizes ext. HD; USB 3.0 seems fine W510

Have had several BSODs in last few days. Two of most recent referred to nusb3xhc.sys
Other symptoms: I have 3 WesternDigital 500GB ext. USB 2.0 HDs none of which are being recognized even when plugging directly in to laptop USB port rather than USB hub I usually use. Same USB port will show a small thumb drive. USB 3.0 laptop port still works. While the WD HDs are all older, worked several days ago but now never show up in Windows Explorer and the tray icon for USB never shows them as I typically click on the latter to eject an ext. USB HD.
Recent changes to laptop:
1) 6.1.2014 installed MS OneDrive (and also on tablet). version 17.0.4041.0512
2) Control Panel add/remove programs shows that Dropbox installed version 2.8.2 just before OneDrive
3) Subsequent to above I did routine Windows update of Important items with no problems. However for several years since about IE 9 or perhaps 10, I have been unable to get IE to install and work, and have been using Chrome for years. I mention this to give fuller picture, but doubt that it is related to current issue.
4) Aside from typical routine updates e.g. Java, Bitdefender antivirus I have not intentionally installed any other software recently.
============
I have barely begun using MS OneDrive so am happy to uninstall it, or go to restore point prior to its installation. BSOD prior to this might have occurred 1 or 2x per year.
I'm pretty good at following directions if they are complete e.g. need full path if you want me to find something on my HD.
Lenovo website for machine type 4318CTO running Windows 7 Pro 64-bit indicates that driver version for USB 3.0 dated 1/22/2010 versin 1.0.19.0 is up to date and that it is NEC device. Device Manager also says is up to date. There is one USB 3.0 port on rear of laptop and two USB 2.0 on side. HP website shows more recent NEC USB 3.0 driver dated 9/16/2011 version 2.0.32.0
Thanks for your knowledge, skill, and help.

I always thought that high-speed USB was USB 1.1. I thought that USB 2.0 was full-speed. But my iMac Core 2 Duo has USB 2.0 (I'm sure) and it says that my iMac has a USB High-speed bus.
Your PowerBook G4 might need service, go to your local Apple Store and see someone there about it. I'm pretty sure that you have a hardware problem.
Steps:
1. Try connecting another USB 2.0 device to that same port. If the device works you have a problem with your iPod. (This is a long shot.) If this happens you should reinstall iPod software.
2. Try reinstalling iTunes.
3. Try calling AppleCare technical support.
4. Try reinstalling Mac OS X. (If AppleCare hasn't told you do this already.)
5. You have a hardware problem. Go to an Apple Store to get it fixed.

USB 2.0 ports on MS-6398E board

I'm new to the MSI forums so bear with me if my style of posting is not yet quite right.
I've got an MS-6398E motherboard and in Win2K the Device Manager lists one USB 2.0 root hub and 3 USB root hubs (no numeric designation).
When I check the properties sheet for each root hub the USB 2.0 root hub shows 6 ports available and with a single device on each of 2 of the other 3 hubs it shows 1, 1 and 2 ports available.
Patently something is not right because it seems that I have 12 ports in total on a motherboard that only has 6 to begin with.
Ideally I would like the 2 devices I currently have plus any future devices to run off the USB 2.0 ports because they're faster.
So I'm open to suggestions.
Thanks in advance.

I just installed my new GNB Max a few hours ago and it uses the same ICH4 southbridge as your board so therfor all the peripherals are the same.
I also see 6 ports on the USB2.0 hub and 2 on each of the other ones.
Looks normal to me since they all seem to work.

Z87-G45 and SOME USB 3.0 ports not appearing in tray/prompting to eject

The 2 lowest USB 3.0 ports on the back panel (Nearest the sound connectors) of my G45 have a weird issue under Win 7 Ultimate. When I plug in a 2.0 drive into those ports, everything is normal i.e. the eject icon and eject warning appear in the tray as usual. However, when I plug in 3.0 drives, no icon or warning appear, but they're fully accessible through explorer etc. USBView reports they're running at full speed, so they're being identified correctly. These 3.0 drives have all the proper messages/icons in all the other ports, including the 2.0 ports where it even warns me that it can perform faster in a 3.0 port. I've tried all the older/latest drivers from Intel and MSI. And ideas or suggestions? Just trying to figure out if my board has a problem or not. Thanks!

Do you just mean they aren't treated as removable drives?
There was an issue that was resolved via bios update similar to this.
Might want to try upgrading to the latest.

Workaround for inability to scan on USB 3.0 port

I've got a late 2012 era Mac Mini (specifications here) that I'm trying to set up as a printing and scanner server for my Brother MFC-7340.
Long story short, I have discovered that scanning does not work when the MFC-7340 is plugged in to a USB 3.0 port. In this case, scanimage returns the following error:
scanimage: open of device brother3:bus4;dev2 failed: Invalid argument
and does not scan. This occurs on both my Mac Mini and my laptop (both running Arch) when plugged into a USB 3.0 port. When I plug the scanner in to a USB 2.0 port on my laptop, however, scanimage is successful.
I have found some mentions of this as a bug here and here, though unfortunately there is no mention of a solution beyond plugging the device in to a USB 2.0 port. However, this is not an option for my Mac Mini since all of its ports are USB 3.0.
As such, I am wondering whether there is any way to force a USB 3.0 port to function as a USB 2.0 port? Failing that, would anyone have any ideas of other possible workarounds? Note I have attempted all the possible fixes/workarounds listed in the first answer to this question on askubuntu that I was able to -- I didn't set "XHCI Pre-Boot mode", for example, since AFAIK Apple provides no mechanism for changing BIOS/UEFI options.
As a final note, I am fairly certain that I am not facing any fundamental hardware limitation that would prevent this setup, since I have been able to use the same scanner with the Mac Mini from inside OSX.

How would I test this out? Would blacklisting xhci-hcd cause ehci-hcd to be loaded automatically as its replacement?
EDIT: I blacklisted xhci-hcd, updated my initramfs and rebooted. xhci_hcd was gone from lsmod, and ehci_hcd had been loaded, so that all seems to have worked. However, now when I run scanimage, for example, I get
# scanimage > out.pnm
scanimage: no SANE devices found
and lsusb can no longer see the scanner (and for that matter can't see an external HDD I have plugged in either).

What is the disadvantage of using USB 3.0 device through USB 2.0 port?

My mac only has USB 2.0 but I'm told to use an external drive with USB 3.0 for better speed. Do I forfeit the 3.0 speed by plugging into a 2.0 port? Even though the 3.0 device is compatible with 2.0, is there a disadvantage?

Thanks for the reply. So basically, if I want to fully utilize the speeds available for USB 3.0 devices, I need a new mac, right? Is there an adapter or workaround? I have memory-intensive sound libraries for use with Logic that are recommended to be stored/run from a SSD or 7200 rpm USB 3.0 drive, so I'm trying to determine if it's worth it to fork out the cash for an expensive external drive, or if it doesn't gain me anything anyways because I'm limited by the USB 2.0 ports on my iMac.

I have a router that has a readyshare USB storage access port that has mp4's of movies. So how can I view them from my iPad 2 ?

Why is my USB 3.0 drive running at USB 2.0 speeds?

(data for visual reference)
USB 1.1 - 12 Mbit/s
USB 2.0 - 480 Mbit/s
USB 3.0 - 5 Gbit/s
SATA revision 1.0 - 1.5 Gbit/s - 150 MB/s
SATA revision 2.0 - 3 Gbit/s - 300 MB/s
SATA revision 3.0 - 6 Gbit/s - 600 MB/s
When COPYING (not updating) large volumes of data from my internal Segate SATA-III Hybrid drive to an external Seagate USB 3.0 drive, this is what is happening:
Both using OSX
Both data COPY (not updating / integration)
rsync (terminal interface) - 50MB/s transfer or 480Mbit/s (exact USB 2.0 speeds)
copy (desktop drag-n-drop) - 1GB every 15-18 seconds (again, exact USB 2.0 speeds)
1GB * 8 = 8Gbit / 15 = 533,333,333 or about 500Mbit/s
1GB * 8 = 8Gbit / 18 = 444,444,444 or about 444Mbit/s
[So, what I have read about rsync -vs- cp is true -- they are identical for fresh copies.]
But this means that either Seagate or Apple is lying about supporting USB 3.0. I read a report in Feb 2012 that while Apple claims to support USB 3.0, they have not enabled the driver to force people to upgrade to Thunderbolt adapters. Did this change with the Summer 2012 and new models?
The ABOUT THIS MAC profile says my USB 3.0 devices are enabled to transfer up to 5GB/s, but clearly, they are running at EXACTLY USB 2.0 speeds.
Even if the Seagate external drive is just SATA-I, then it should be able to deliver 1.2Gbit/s -- 3x what I am seeing! The fact that the speeds are EXACTLY USB 2.0 tells me the MacBook Pro, while claiming USB 3.0 speeds is nothing more than a USB 2.0 port.
Can someone explain what is happening?
kai

I am having the exact same issue on my 2013 MBPr.
I have two Seagate GoFlex USB 3.0s, one plugged into the regular 3.0 port (450MB/s) on the left and the other plugged into the high-speed (5GB/s) 3.0 port on the right. When doing a simple copy/paste from the one drive to the other, I observe the following speeds:
Peak Read (USB 3.0): 36.2Mb/s (288Mbit/s)
Peak Write (USB-HS 3.0): 48.7Mb/s (384Mbit/s)
This is far below the 620MB/s for 3.0 and is more around the 35MB/s USB 2.0 standard.
So, I'm likely to agree with the original compaintant that the 3.0 standards aren't being employed by the MacOSX USB drivers and I'd hope to see a fix soon for these issues lest people start moving off of the Mac platforms to other vendors who adhere to industry guidelines.
