I have just updated an old computer with a NEC USB 2.0 PCI 4+1 card. The motherboard normally only has old USB connectors, I want USB 2.0 for the speed.
The card is detected fine in win xp prof sp2, and configures according to the card manual in the device manager.
Everything seems fine until my external hard drive is connected and i start browsing on it. When viewing pictures on the ext drive, for example, windows cannot preview the pictures, and after maybe ten pictures (of which maybe one manages to get viewed) i get the USB_BUGCODE_DRIVER bluescreen.
When attempting to copy files from the ext drive to the system disk, this seems to work, but when the files are opened there are errors in them. Here the blue screen is not so common.
When the ext drive is connected to the old USB ports, it works fine (but SLOW).
I've been trying a lot of different things here and I'm stuck. Supposedly, there was an issue like this that was fixed in SP1, but that is old news since my windows is up to date.
MB: Epox 8KHA+, bios VIA KT266A rev 09/16/2003
CPU: Athlon XP 1700+ @1.47GHz, no overclocking
GPU: GeForce3 Ti500
ext drive: packard bell store & save 400GB (w/ independent power supply)
All help would be appreciated, this is ruining my holidays!!
did you use the drivers on the cd? when i used one of those in the past i think the windows drivers where super slow and may have been bugged....try the cd drivers...if you dont have the cd' i will look around and find it....
Since i used a card like that on a durron 1000 i doubt there is any chipset that can not handle it
Sorry bout that, looks like it was fixed with a service pack....or at least it runs its best with windows drivers now, i DO remember a time when i needed to install the special drivers to make it work right....
Its also hard since my USB drivers are patch 7 ways from sunday to allow for 500 reports per second vs the standard 125.....
http://driverguide.com/ is a good place for drivers.....just look at a few adds say no thanks and get your drivers....the onces on CD2 are U2v2_062.exe.....maybe they will work better for you....in my case i think it's my hacked(500-1000 reports per second) drivers that are causing me problems with the cards speed.....It extracts drivers to C:\WINDOWS\Drivers\ousb2...those drivers are only used for the NEC Enhanced USB....and the usb 2.0 hub....the open host controller's do not need any drivers.....
In the end, I had to give up, trying new drivers or shifting the card around to avoid IRQ-conflicts did not help. The computer will run on USB 1.X indefinitely, and I will return the card. Either the USB-card is broken or the motherboard is simply too old.
