USB device not recognized (any)

Joh — Sat, 30 Apr 2005 09:39:02 GMT

Hi,

Since a few days I get the message 'USB device not recognized' for every USB device I connect (camera, printer, extra hard disk). Although not every.... my USB mouse is still working when I connect. Yesterday I did a recovery for my C-drive. I own a PCV-V1/G. Still I continue to have the problem. Who can help me? Other question: When you do a recovery of C, is the drive then formatted?

Thanks,
Johanna.

I've had a look but appearantly these drivers are not for XP (I have XP) only for ME, 98, etc. 😞

Sorry I was mistaking (I've seen so much sites the last few days). These drivers are not necessary if you have used the recovery CD it says... and I did so I didn't give these drivers a try. But you never know... I will do this know and come back with more info.

Hi again,
I've downloaded and checked but the drivers are the same 😞
More ideas?

Go to device manager (right click my computer, click on properties, click on the hardware tab, click on the device manager button).
Open the tree USB by pressing on the + next to it.
Right click and uninstall the USB hubs.
Restart your VAIO

Hi Kee-Lo,
I tried this but sometimes my system goes 'hanging' or my infrared mouse/keyboard (which work with ir and usb) hang. Yesterday I did a complete clean install but... no luck. I tried to attach a usb 1.1 stick. This was OK. Anything that has to do with 2.0 (camera, other usb stick, WD hard drive and HP printer) won't work 😞

Hi Joannah

Only one of the ports seem to be USB 2.0 too
If you can borrow a powered USB2 hub that might help.

Normally a USB2.0 device is downgrade compatible. If you would connect a Printer or a Camera which supports USB2.0, with an USB1.1 Port then you would have only a lower speed (approx 11Mbit/s). That's the only thing.

It's that the USB-Port itself is the problem, maybe any hardware fault.

Depends how much juice it's pulling from the USB hub too seb

Re: USB device not recognized (any)

normally max.500mA. And like I had said, you can check that in the devices manager. And camera need no energy from the USB port.

True, but the DeLL my parents have didn't put out the 500mA for some reason

Oh and that Lexmark printer they have is a juice guzzler!

The only device which I have and which needs 500mA is my scanner.
My HP Printer has his own AC-adaptor and I use it via a parallel Port.

LOL, what is a guzzler?

Something that drinks a lot (electricially - you wouldn't say that for someone who drinks a lot)

He guys,
Thanks for thinking with me.
I understood that my PCV-V1/G has 4 high speed USB ports (2 controllers). That's also what I can find on the Sony site. Strange thing is that it always worked perfect...until last week. I've have a 2.0 hub (not powered). Also if I connect that (no usb devices attached) I get the famous message. Could it be hardware?
Cheers

No idea. I think it's a hardware fault. Any problem with the power supply for the USB ports. I think you must send your VAIO back for repair.:smileysad:

Sounds like it.

Hi guys,
Thanks again. I've opened a case with Sony E-support. Maybe they can help me.
Anymore tips in the meantime would be more than welcome.
