How do I change USB ports?

September 28, 2008 at 03:04:44
Specs: Win XP SP3, Intel Pen 4 1800MHz 1Gig

Hi all.

I have fitted into my PC a USB 2 card that is clipped into the Mother Board giving me 4 USB 2 outlets facing the rear of the tower.

Two of these are in service, one is for my HP printer/scanner and the other is connected to a powered external HD that is only turned on when required.

The 3rd and 4th is free. One of these I bring to the front of the PC via a 1.5 metre USB 2 cable so that I can plug stuff into as and when required, and here lays my problem.

It does not matter if I connect any other USB 2 devices via one of these free sockets either with the 1.5 metre cable or the devices own short cable, I get a message up telling me that this device is a USB 2 device and will run faster in a USB 2 port.

I am then presented with a window that shows words to the effect:

Via USB Enhancement Host controller.
the hubs in bold have free ports that can support the hi-speed USB device.

(Then in bold print)Via USB enhanced Host Controller.

Underneath that I am shown "USB Root Hub" with 4 ports.

What do I do, how can I find out or be able to connect to one of these hubs to get my USB 2 connection?

Regards

Someone more knowledgeable than I will expand on this but a 4 port hub will always only deliver the capability to run USB2 applications as USB1.1. It has to do with the power delivered to each port.

Over to the brains!

If your add in USB controller card has FOUR ports then it should have TWO controller chips on it.

Normally a USB controller supports TWO USB ports.

If this is the case, AND both controllers are USB 2.0 then the cable may be acting as the throttle slowing connection speed down.

Is the cable a simple extension cable or does it have multiple ports on the end?

What type of device are you attempting to use on the extension cable?

You could try a couple of things. First, you need to verify the specs of your add in card to see if it has two controllers both of which are USB 2.0.

Next, the printer that is always connected may be sharing a USB controller with the extension cable. Changing the extension cable to the other unused port may help.

It is possible the card you added only has ONE controller and is acting as a hub as explained above.

It also may be the card has TWO controllers with ONE USB 2.0 and ONE USB 1.1. In that case switching cables around may give you USB 2.0 to the front.

Do you know the model and brand of the add in card?

edit

I found the link below for a VIA USB controller chip that supposedly can support 4 ports at USB 2.0 speeds.

Without knowing what VIA chip is on your card I can't speculate further.

Hi guys.

I understood most of what you said Othehill, to a point. To this end I have made 2 screen captures joined together , the first is taken for windows control Panel System and the other with Aida 32.

Hopefully you you can make some sense of it and advise me further:

At the moment I am using a USB 2 cable bought to the front of the tower to drive my bits.

Thumb drives do not barf at the USB 2 barrier, but when I connect to the same cable a 20 Gig laptop IDE drive USB 2 connection the system barfs. There is no external power with this IDE connection, only the USB 2.

I have tried swapping around different USB 2 sockets at the rear, but still no joy.

I do not know what make or model the card is without ripping the box to pieces.

How would I find out what the specs are?

I am still looking around the web trying to find a program that may help to identify.

I have Sisoft Sandra which I will install tomorrow, maybe that will tell me.

Regards.

Are there also integrated USB ports on your computer?

Have you tried connecting the 20GB external directly to the rear port in order to eliminate the cable as the cause?

USB standards allow for a max. cable length of 5M. Therefore your cable length should not be an issue.

That said, self contained external drives can be problematic. Current overdraw can be an issue.

Does the drive function properly on other computers?

If you right click on the USB components listed in Device manager and select properties you can see what the current draw is for that device.

Hi there.

Integrated ports are USB One only. That is why I installed the USB 2 card to overcome this problem.

Yes I tried a direct connection of the external drive as you suggested, no joy.

The external HD comes with it's own short USB 2 cable. Cable length is 30 Centimeters.

I have no joy with using only this short cable either, the result is exactly the same as if I were to use my 1.5 meter extension.

The External drive is not malfunctioning to the best of my knowledge as I have data stored on it and I can access it without any dramas.

In Device Manager, if I go down to USB it only shows the hubs as I listed earlier it does not say "this device is connected to that hub" etc.

If I go to Device Manager, under disk drives the external HD registers as Generic USB Disk USB device. Right clicking on properties does not give me current draw.

I have some more read out data in case it helps:
