Hello everyone,

I need your help again.

I am having this strange problem, except for the mouse & keyboard my computer doesn't detects any USB device

I have tried to switch mouse & keyboard to all the 8 ports and they do work. But nothing else except these two.

The thing is ... whenever I insert a device in the usb port, The computer does detects it with its proper name, But it asks for its software .. but there are no drivers for those devices, And if i still install the software CD it comes with, It doesn't works.

Please tell me the workaround for this problem.

Like i said it partly detects it (displays the proper device name) but still prompts for its software even if it doesn't comes with any.

Please help me.

Thanks and regards



I'm currently downloading SP2, will see if it solves the problem.

But till then if someone have any suggestion, i would appreciate it.

You didn't say which Operating System you are using. If you are using Windows XP, see this:

http://support.microsoft.com/kb/310575

Scroll down to "Malfunctioning, incorrectly-configured, or missing device driver".

None of the solution from that link works.

I installed SP2 but it doesn't works neither.

I'm on Windows XP Pro 64bit.

Here's my system config:

Q6600 Processor
Asus p5nesli mobo
8800gt
1gb ram

I'm being really impatient now. Someone please help me.

Only the mouse and keyboard works .. nothing else.

Go into your hardware manager, and then to the USB devices, right click on each host controller and select properties. See what percentage of USB bandwidth is being allocated for each one. 10% or so should be about right. Is any of them using more.

i checked and its shows that none of them is at 10%. There are a total of 6 options to check, out of which two of them shows 24 & 22% and rest are showing in mA format.

Please tell me what should i do ?

just wondering, when did you install windows 64bit? and are you sure there are drivers for the devices you are trying to use?

I build this machine just a few weeks back, I tried connecting my printer but it didn't work and since my exams were about to begin I couldn't check what the problem is and now its really making me impatient

Like i already said there are no drivers for those devices, And if i still install the software CD it comes with (which has 64bit compatiable drivers), It doesn't works.

And I dont want to switch back to 32bit

Perhaps this will help:
