Posted 17 April 2006 - 11:53 PM
I do have a self powered midi keyboard I use and also an HP printer. when plugged in, neither work.
I used that link u gave me and also found this: http://support.micro...om/?kbid=816843
I've contacted them for the hotfix, though im not sure if it will work.

tried fighting with sony but just dealt with outsourcers and scripts. I regret going with my previous employer to train those poor overqualified fellahs in spam. But it was a free trip to India expense paid;)

Since these devices work in other systems, we can assume that the problem is on the Sony, correct?
You replaced the previous motherboard due to this--why are we assuming it is not simply another failed motherboard?
Putting that question aside for the moment--let's go back to basics
For USB to work, you need
Support from the BIOS--what is the bios date on the PC--can it be updated?
Support from the Operating System--Windows XP sp2, so you're covered
Physical USB ports--all failing, so either motherboard or...?
A USB Device--multiple devices, all work, so we can rule this out
The correct USB cable for the device--hmmm, have you switched cables? A short in the cable could be at the heart of it--and furthermore, HOW LONG is the cable (and hopefully no extensions). Ideally, a usb cable should be no more than 6 feet, though the "standard" max length is 16.5 feet. Poorly shielded cables and cables with shorts will create all kinds of issues, especially with crappy, inexpensive usb controllers common in mass market PCs...
Drivers either from the OS and/or the peripheral maker--should not be an issue

However, I can't think of anything else. I did do the AMIBIOS update from Sony's site but not sure what that was for.
All cables are fine.

Also, just because the USB port is sending power does nto mean it is sending enough power. a usb device tranfers 5 volts--maybe it is not pushing enough?
Which leads us to another possibility, though remote, but then wonky power supplies can lead to some of the weirdest symptoms. A power supply actually supplies three different volts--12volts, 5 volts, and 3.3 volts...but the 5 volt rail only does one thing, well, two things. It operates the on off function, and--you guessed it--usb. (it used to supply the videocard to, until the videocard's became more advanced)
It is possible--possible--that your 5-volt rail is dying. This is fairly easy to check...grab another power supply from another known good system and plug it into the zony's motherboard and drives (no need to actually mount it in the case--just set it on some books so it is not touching the case and something else to avoid a short and run the wires into the motherboard and drives.
See if that works

Hello May I interject an issue about USB cables
The printer is the only HP product. The camera is olympus. Just direct transfer using a usb cabl
Is the direct Transfer cable used for any of the other USB Devices? This is a [Direct Transfer Data Cable] & will not work as a USB Device cable It does not have the +5V wire connection to pin . So therefore a [No USB Power] Indication will be indicated/shown.

Oxygen 8 Midi keyboard. (usb or powersupply adapter)
Olympus Digital camera (uses a usb cable that connects from camera to usb port to transfer pictures)
HP printer. Only has usb outlet.
microsoft usb wireless mouse
belkin wireless modem.
All of these devices use different cables. All recieve power but are not recognized by Windows
:- ) how that helps clear up some confusion
thanks again for the constant support!

In your case it might be an hardware problem on USB controller.
If you are with SP1 or 2 with base microsoft driver they must work correctly.
Those USb ports had correctly worked in past? They stop working after reinstall?
I have a similar problem on PCV-RS402 desktop.
In my case i have the USB 50% working: no way to set them to HI Speed mode
In normal mode I can't open big files (>100Mb) from USB drives such as PenDrives or external HDD...
I have no USB voices in BIOS setup...
Tried to install all updated drivers from Sony and Intel website but no way to make them work.
The latest BIOS update from Sony (reading the info file) is only for this:
- Improves the stability of the unit after resuming from hibernation or stand-by.
My actual bios version reports:
Date: 12/10/03 09:06:07
Do you have a USB mode voice in BIOS setup???
Or there is any way to enter an advanced BIOS setup program with full controls? Or is there an hardware solution (jumpers or anything similar)???
