Solved what is a usb composite device driver

May 27, 2011 at 10:18:54
Specs: Windows Vista

I am not a techie person, so please be patient.

I continue to have a pop up that says:

"Your USB composite device can perform faster if it is plugged into a high speed port"

I click to find these ports.

Up pops a tree showing: "USB Root Hub (10 ports)"

Then a list of 10 identical: "Unused Port"

What does this all mean?

I thought that we are tech support people, guess not?

Your laptop has 6 USB ports.

Devices can run at USB 1.1 speeds even when connected to a USB 2.0 port as I inferred above.

In your case I am going to guess that your 5 in 1 card reader is sharing a USB controller with two of the UPS ports. Probably the two that stand by themselves. Those ports may degrade to USB 1.1 speeds.

I have a keyboard with two USB ports built into it. The keyboard is connected to a USB 2.0 port. The two built in ports are considered to be a hub and degrade to USB 1.1 speeds. When I connect any device to the keyboard ports I get that same message. This is due to a USB CONTROLLER only having a finite amount of current available. It is shared by all the ports connected to that controller.

Normally two ports share one USB controller. However, card readers are usually piggybacked onto a controller and share with two ports. So that USB controller will degrade to USB 1.1 speeds.

Removing any memory cards from the reader MAY allow the two shared ports to then run at USB 2.0 speeds. If a device is not designed to need USB 2.0 speeds, which the two devices you mention above are not, then they will not run at USB 2.0 speeds in any event. This is by design and should not be taken as an error.

If you have been using the same two ports for more than the month your mentioned the message may have started due to the presence of a memory card in the reader or a Windows update. The reason is not important, there is nothing wrong with your laptop.

It would be easier to answer your questions if we had the specs of your computer or if pre-assembled then the brand and full model.

Either the USB port you are using for that device is version 1.1 or you have a USB hub in the mix. Card readers with USB ports are one example. USB ports on a monitor are another.

If you are using a high bandwidth device connect it directly to the USB ports high on the back of your tower.

Another possibility is that you need to install the motherboard chip set drivers.

Did your computer come with Vista pre-installed?

Thank you for your reply! I have a Toshiba Satellite P205D Laptop. Processor: AMD turion 64x2 mobile technology TL-60. 2GB RAM. It came with Windows Vista Home Premium installed. 32-Bit operating system, 2 processing cores.

This pop up started about a month ago. I have 10 USB ports, 4 on each side and one on each side back. I only have my wireless mouse and a headphone set plugged in. Have tried moving them around, but to no avail.

Thanks for any other help, and your patience too. MaryAnne

According to the spec sheet, you have 4 usb 2.0 ports. refer to your manual to see which ones they are. You will get that message when you plug a usb 2.0 device into a usb 1.0 port.

Well, I am not sure why you are getting that message now but I will say that your mouse and headphone can't perform any better than they are. I would not worry about it if everything else is working OK.

Are you sure you have 10 USB ports? There are a number of Satellite P205D laptops models listed and none appear to have 10 USB ports.

I think your laptop is the one I linked below. Have you installed all the Vista updates including sp1?

Thank you both. And apparently age is taking away my ability to count. I did a physical recount of the USB ports. There are 4 on the left and two on the right. Dah! I have looked up the web site info and will have to look for a 'tech support' person to help me. And wish I had a printed manual. I have browsed the online one, I didn't see reference to 1.0 vs 2.0. The manual seems pretty generic. I purchased the laptop from an electronic big box store in February 2008. Soon after purchase there was a bad lock up and it was sent to Toshiba for new firm ware. Otherwise it has been working well. MaryAnne

Thanks for your great reply. And no insult intended re 'tech support'. Thinking of someone who could sit in front of my computer and help in person. But your online help is invaluable. Thanks so much. I did a print out of your info. Will study it over. I had an eye opener re windows update. I guess that could have caused this to start. I have had friends with Vista update weirdness. Thanks so much for taking the time and your patience!! Very appreciated. No longer feeling lost and confused. Have a great day.

Hi there, hoping you can help me as well. I have an Acer Aspire 5542-5462 laptop w/ Windows 7 and the product details indicates I have four 2.0 USB ports (2 on the right side, 2 on the left). Today I connected my 1TB external "SimpleDrive" hard drive in order to do a backup which I'd done previously but my last one was afew months ago# and got the same "This Device Can Perform Faster - Your USB Mass Storage Device can perform faster if plugged into a hi-speed port" message as others have. This is the first time I've received this message.

Below that is a window with the heading "The hubs shown in BOLD type have free ports that can support the HI-SPEED USB device." and in the window it shows 2 separate "Standard Enhanced PCI to USB Host Controller" and under each it shows a sub-heading "USB Root Hub #6 ports# in BOLD TYPE. Under the 1st USB Root Hub it reflects all 6 as being "Unused Port" and under the 2nd USB Root Hub it reflects all but the 5th of 6 as being "Unused Port" and the 5th as "USB Composite Device".

I went online to find out about the USB "This Device Can Perform Faster" message and what it meant, along with solutions. I've tried the following:


-Went into the "Device Manager" window and the "Universal Serial Bus controllers" sub-menu which reflects, in order, 2 "Standard Enhanced PCI to USB Host Controller", 4 "Standard OpenHCD USB Host Controller", 2 "USB Composite Device", 1 "USB Mass Storage Device" and finally 6 "USB Root Hub".

Per online instructions I right-clicked on each one and used the "Update Driver Software" #via a "Search online for updates" option# and received a "The best driver software for your device is already installed; Windows has determined the driver software for your device is up to date" for each and every one.

-Secondly per online suggestions I checked each USB Root Hub and all reflected as running at "full-speed" instead of the optimum "hi-speed" #which was indicated as to what should be showing if using a true 2.0 USB port#.

So basically what I'm asking is if I have the current drivers already installed and my laptop's 4 USB ports are all supposed to support 2.0, then why aren't those USB Root Hubs running at HI-SPEED instead of the slower full-speed? Is there something I've missed? Or is there nothing wrong at all? My previous backups have taken upwards of 12+ hours to complete and I want to make sure that I'm using the fastest means possible. Thanks very much in advance for any help! Best regards,

Kurt

Your situation is identical to mine. I still have no resolution. I did realize that there is a real problem. I can use my video or my mike, but not both at once. So when I skype, I can see or speak. Taking it in to someone more knowledgeable than me to look over in person. Good luck with yours.
