USB 2.0 ports only running on 1.1

April 11, 2006 at 12:44:24
Specs: windows xp, ddr400 2 gigs
All my usb ports that are 2.0 are seeming to only run on 1.1... windows tells me that the ports can run faster with a high-speed host. I do have a high speed one...:/ Any ideas on why my usb ports are running like this?

I thought one of my PC had USB2 when I got the same message. After I double-checked the specs I found that it was USB1. So, I bought a PCI USB2 bundle from

You need to have Service Pack 2 from Microsoft to use USB2.0. If your Mobo supports USB 2, then maybe you need to update the drivers. Good luck.

It makes them think you're up to something...

Service Pack 2 is not a requirment for USB2.0.
Make sure your computer's BIOS is set for USB 2.0 (which in the case of your mobo it should be the default).

If it is, download this Microsoft Update if you don't have it already:

AMD Athlonxp 3200+ OC
Asus A7N8x-deluxe-E
ATI AIW 9600pro
2x WD SATA raptors/raid0
Corsair XMS3200
16x Lite-on DVD
12x DVD-R
48x Lite-on CDRW
Aspire Super Alien Case

Hi Fish
Is the device (or devices) that you have plugged into your USB2 outlet(s) USB2-compliant?
For example, if you plug a 3-4 year old digital camera into a brand-new USB2 port, the chances are that your photos will only download (or upload) at USB1.1 rates.

Im trying to drag music off of my ipod onto my desktop :/

When I plug it in, it says it can run faster, if I had a 2.0 port...

If your computer USB ports are specified to be USB2, your iPod can transfer at USB2 rates, the cable between the two can handle the higher transfer rates and, finally, the correct drivers are installed then there is no reason why you should not achieve the higher rates.
There really are no secret mantras or magic potions that need to be applied.

You haven't actually mentioned what transfer rate you do get. Is it below the max rate for USB1.1 (AFAIR is 12Mb/s where "b" is "bits" not "bytes"). Anything above this suggests that you do in fact have USB2 even though it might still be a long way off the max USB2 rate (480Mb/s).

The software package USBInfo (google for it and download; it's not free but you can use the trial version for 15 days or something). This will do a complete analysis of your USB controllers, hosts and ports and identify which are 1.1 and which are 2.
However, if you have a device which can only deliver at USB1.1 rates hooked up to your computer, USBInfo will identify your computer port as USB1.1.
So care is needed in the interpretation of the results.

Good luck

It lists the ports as 1.1 , but it's CLEARLY 2.0, just to let you know...I formated my computer about 3 days ago, and them it started to do this... Should I try the boot "Repair windows" thing?

With respect, you really need to be a little more forthcoming and clear in your posts if you want anybody to help you.

You say:
1) "It lists the ports as 1.1"; What is "it"?

2) "It's CLEARLY 2.0"; To whom is this clear, what exactly is clear and why is it clear? It's certainly not clear to me as you haven't explained why it's clear to you.

3) "I formated my computer about 3 days ago, and them it started to do this".
Do you mean you did a clean-install of your OS? What, BTW, is your OS?
If you did a clean-install, are you sure you re-installed ALL of the appropriate drivers, including those for your USB2 ports?

4) "Should I try the boot "Repair windows" thing?"
What is the "Repair Windows" thing? Do you mean a repair-install of your OS? Why would you want to do this if you've just clean-installed it?
Alternatively, do you mean the Repair function in some versions of TweakUI?

May I suggest that you try and avoid using terms such as "it", "to do this", "thing" without an accompanying clear explanation. While it may well be clear to someone looking over your shoulder as you type what you are talking about, to someone who may not even be on the same land-mass as you it could well be less clear or even appear as unintelligible gibberish.
This is then unlikely to elicit the help you need.

Good Luck

Alright, last I checked if I "boot CD" using windows xp, it gives me and option of a clean install, partitioning my hard drive, and "press R to repair windows". Would it be a good idea to go ahead and press R to repair windows? When I said it's clearly 2.0 usb ports, I meant to say that it says on my motherboard manual: 6 2.0 usb ports.

Im running on that mobo.

"Rear Panel Ports
PS/2 2
USB 6x USB 2.0
IEEE 1394 1x 1394a
S/PDIF Out 1x Coaxial
S/PDIF In 1x Coaxial
Audio Ports 6 Ports"

It lists that on the site where I bought it, and on the box it came in. Before I formated It was working fine, I've installed the drivers for my usb ports, and the ports only list as 1.1. I dont know why, but they are. I dont know what else to tell you, I just need to know If I try this Windows Repair process, will it screw anythign up?

OK, thanks for clarifying your situation.
Given that you use WinXP there should not be any problem running USB2 ports.
The fact that they don't run suggests that you could well have some corrupted system files that are preventing this.
In this case, a repair-install, which is what you are proposing, could well fix this.
Also, a repair-install is supposed to take place without interfering with your apps or stored data--so, it should not screw anything up.
Nevertheless, in the world of computers, it is always a good idea to back-up any important stuff before you do anything a little out of the ordinary like a repair-install.
In my opinion, the best thing is if you have an external HDD (or can temporarily borrow one from a friend) where you could transfer everything except your system (i.e. Windows) files and then disconnect the External HDD before starting the repair-install.
There is a very good article by a guy called Michael Stevens (MS-MVP) on the repair-install proceedure. I recommend you to read this before going ahead. You can easily find this through Google (Google for: Michael Stevens Repair-Install).

However, the question remains as to why the clean-install you did seems to have messed up your USB ports. The clean-install is supposed to FIX things not mess them up. Are you sure your CD, and your CD reader, are in good condition? If not your repair-install won't work either.

Good luck

Just a couple of other thoughts on your situation:

1. Although a repair-install probably won't do any harm, it mightn't do any good either. Really, a repair-install is nothing more than a half-assed clean-install. Given that you have recently done a clean-install, it may be best just to repeat that. However, this time be sure to follow some instructions such as the article on clean-install also by Michael Stevens. These include making sure your CD and your reader are clean.

2. I just remembered I had a situation about 9 months ago where, after a repair-install of WinXP, my External HDD wouldn't work. It turned out that it was my USB2 ports that weren't working. However, just reloading the drivers had them working again in 2 minutes. However, this shows that, in my case anyway, rather than the ports acting as if they were 1.1, they just didn't work at all.

3. It might be a good idea to do a little googling on your situation, for example: loss of USB port functionality after clean-install of winxp.
If this is what really happened to you, for sure it's happened to somebody else.

I have a DFI Lan-Party SLI-DR that has given me no end of problems with the USB 2.0.
NForce drivers from Nvidia always break the on-board network adaptors (both of them), and all the USB ends up running 1.1.
If I use the drivers that came with my motherboard there does seem to be a magical order in which you have to do things to actually get them to work properly and things do all of a sudden one day change without you knowing, which you do not realise for some time until you transfer files onto an external drive etc.

This has been a great frustration for me as I am very computer savvy being a software engineer by trade.

DFI Lan-Party appear to offer no assistance for this particular problem (at least nothing in english that helps), and yes, everything is up to date, patched, firmware updated, the works.
