Does Epox 8rda+ support hi-speed USB 2.0?

[ajf3]

Hey all,

Have the 8rda+ which sports 6 usb 2.0 ports built in... However, I can't find anywhere where it specifies whether or not these are hi-speed ports (for usb 2.0 hi-speed is 480, full speed is 12).

I'm running XP sp1, and just re-installed the nForce 3.13 unified drivers, but still no-go. When I plug in a hi-speed 2.0 device I get the 'hi-speed device plugged into a non hi-speed port' message.

Do I need to buy a PCI card, or is there a way to get these 6 usb 2.0 ports to run at hi-speed?

Thx!

First off, get the 4.24 UDP set and use those drivers instead of the 3.13 drivers.

Second, to enable USB 2.0 you have to turn it on in the BIOS. It's in the Integrated Peripherals section somewhere. You'll then have to install the drivers for it.

Thanks, I'm grabbing those drivers now to give them a try.

I di have usb 2.0 enabled in the bios - the issue is that there are 2 flavors of usb 2.0... 'full speed' is 12mbps and 'hi-speed' is 480 mbps. Are you saying that I can get the 480, or just the 12?

Installed the new drivers... same deal - only getting 'full-speed' (12mbps) usb 2.0. When I plug in my reader it still gives the 'connected to non hi-speed usb 2.0 device' message.

Has anyone gotten the built in ports to work at hi-speed usb 2.0?

Hmm... heard back from an epox tech. Claims that USB 2.0 hi-speed (480) is supported on this board, so it must be a software issue... any other drivers I can try?

I've never heard of two different USB 2 speeds before. As far as I knew, all USB 2.0 was 480MB/sec. I'm at a loss as to how you'd fix this. Sorry.

Thanks for giving it a go...

btw - usb.org:

Because the USB 2.0 Specification encompasses all USB data transfer speeds, low (1.5Mb/s), full (12Mb/s) and high (480Mb/s), it is important that vendors clearly communicate the type of product on packaging and in marketing and advertising materials. Inconsistent use of terminology in combination with the existing general misconception that USB 2.0 is synonymous with Hi-Speed USB and/or failure to display the Certified USB logo on qualified products creates confusion in the marketplace. The correct nomenclature for high-speed USB products is "Hi-Speed USB." The correct nomenclature for low or full-speed USB products is simply "USB." This should be taken into consideration for product naming.

It looks like full speed USB 2.0 is no faster than USB 1.1. And why would they have a low speed USB 2.0? What's the sense of those two ratings?

Anyways, sorry I was no help to you ajf3.

USB 2.0 encompasses all previous speeds in order to provide compatibility with older products. Also, depending on the application, the lower speed may allow for a more robust communication (longer cables, less sensitivity to noise, etc.) The lower speeds might therefore be more useful for industrial applications.

I too thought that if something was USB 2.0 compliant, then it was also Hi-Speed. I didn't realize things could be marketed as 2.0 but then be "full-speed" only. Thanks for the clarification.

Do you need to configure the Ports to run @ hi-speeds somewhere, in addition to simply activating them? Maybe you forgot to do that?

-D'oh!

Here's what to do:

go into Device Manager and click on the yellow ? that is beside the USB. Go into Drivers and click update. Wait until it finishes installing your high speed USB 2.0 (480 mbps) ports.

Enjoy.

That was easy.
