Dell precision not recognising usb 2.0

When i plug a usb device such as an external hard drive or a card reader into any of the 8 usb ports i get a mesage saying i should use a usb 2.0 port for faster data transfers.  To my knowledge they all are 2.0 or at least the ones on the front of the tower, right?  I have tried activating from bios as suggested but i cant find the option in there.  any help would be appreciated.

Re: dell precision not recognising usb 2.0

Sounds not,  some of the older systems only have 1.1, Usb 2 is not all that old (about 2-3 years).
you can upgrade to USB2 bu adding a USB2 PCI card to your system, this would give you some ports on the back and it may be possible to link the ports on the front to the new PCI card to upgrade those as well (depending on how they are connected to the mobo)
you can get USB2 cards with a Pin header which would allow for a pin block connection.

I cant get my Dell Precision 690 to recognise a hard drive

Double check the bois to ensure you have all the Sata ports turned on. I have found in some Dell computers the only ports turned on are the ones in use when shipped from the factory.

New Dell desktop can't recognize external hard drive

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

Usb port problem

It MUST be plugged into a usb 2.0 port NOT a usb1.x

Some usb devices only like the usb port they were first installed / used on. Try to stick to using the exact same port

You should not plug it into a usb hub

If you are using an external card reader for your phone card, make sure that it is not plugged into a hub and only use the cable that came with it, not one that fits but didn't come with it.

Also make sure your motherboard drivers are up to date and that there are no exclamation marks by any hardware in the hardware tab from system in the control panel.

If you are still having problems then there could be other issues.

USB issues with Dell PC

I think you answered your own question.

Yes its true that many pc's dont proide enough juice to the ports.

This is even more noticable if you have lots of heavy drain usb devices. small external hard drives are esp bad in this area and if you are unlucky enough to own a "USB powered" printer these too can have adverse effects on usb performance.

Location of USB Root Hub

Hi dottyo,

Generally the front USB ports on a computer are USB version 1.1, good for USB keyboard and mouse or printer.

But, almost always the USB ports on the back of the pc are USB version 2.0 which is what you are looking for. Try any ports on the back of the pc case.

Hope that helps!

USB Header

The only way is to purchase a USB Board to install in the PCI slot, but that would be overkill since you PC already has 4) 2.0 USB ports. I would exchange that internal reader for an external reader.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Imstalling internal card reader

Well, installing an internal card reader without a spot on the motherboard, is a little hard to do. I would suggest buying an external card reader. They are a little cheaper, and a lot easier to setup and use, since they just connect to a USB port which all computers have.
