More info?)
As previously mentioned I'm using Windows 2000 PRO with SP 4 and all
updates thru the Feb. 2005 releases from Micro$oft. All of which I
deleted during testing of the USB problems and reinstalled.
Also fired up on table the second A7N8X-E Deluxe Rev. 2.0 motoheroard
from out of box and moved everything over to it. I only found the
problem with SanDisk Imagemate SDDR-89 USB 2.0 12-in-1 card reader.
The other USB 2.0 devices I own work fine. Thus same results.
So if you follow back up this thread you'll see there is an admitted
fundamental 'jitter problem' in the USB ports with the combo of this
motherboard and chipset implementation which now appears to be
consistent on the two A7N8X-E Deluxe Rev. 2.0 we own.
Check out this article
http://www.techspot.com/vb/printthread.php?t=7934&page=1&pp=20
written 09-27-2003 and you'll see " a list of devices known to have
problems with this board :
* 6in1 Internal Reader 3 1/2 usb1, Flash card reader card X4-USB
* MP3 Player DAP 128 Mb (Additek)
* PNY 6in1 Player ( metallic grey look ) which doesn't even work on
the a7n266-e
* Creative Muvo 128Mb ( Solution : flash with new firmware update,
instructions contained in ReadMe file )
* The Archos JukeBox 20
* Compact Flash USB HAMA Player
* CF USB Player from Crucial"
The troubleshooting techniques mentioned in the above article are same
as 'Paul' suggested. Which have not cleared up the problem on my two
mobos.
Thus I'm back to the options of testing a PCI USB 2.0 card and a hub -
probably "Targus (PAUH212U) 7-Port USB 2.0 Hub".
Both of which will wait until later in the month when I have time to
play with techy testing.
