Default Which USB port is 2.0 on P4P800SE MOBO?

I've been using my ASUS P4P800 SE MOBO for a couple years now with XP Pro. A month ago I upgraded to Vista Ultimate and it's been working fine.

Two weeks ago, after running Vista for two weeks, I added a Belkin 4-port 2.0 USB hub. I have a USB powered scanner, a printer, and a APC UPC backup power supply plugged into it and they've all been working fine.

Today, out of the blue, I get the message "Your Generic USB hub can perform faster if it's plugged into a HI-Speed port."

All along I assumed that all four ports on the back of my PC were 2.0/1.0.

Presently I have a keyboard, a mouse, an external USB HDD and the 2.0 4-port USB hub plugged into the four USB ports on the back of the PC.

I checked ASUS and there are no USB drivers for Vista. All the USB drivers are Microsoft's and were installed via the Vista install.

Is there a way I can test whether a USB port is 1.0 or 2.0?

Suggestion please.

Thanks,

Kerry

Use Sisoft Sandra to test the USB storage speed of your USB HDD; USB 1.0 is ~1.2Mb/s

or copy a file from your HDD to your USB:

a 72Mb file
USB1.0: 1 minute 20 seconds
USB2.0: 44 seconds

Thanks jmke,

The Sisoft Sandra Lite readout is a bit confusing, all sorts of USB ports.

Just to be clear. The four USB ports that stick out on the back of the ASUS MOBO which according to the ASUS P4P800 SE manual are supposed to be 2.0/1.0, are in fact not all hi speed? For example SsSoft Sandra says that my mouse is plugged into Controller 24D2 and that it's Low Speed, 1.5 Kbps, the same for my Logitech MX Laser mouse (controller 24D4), yet the ports are suppoed to be 2.0.

In any case I'm not getting the advice message any more.

Your Mobo is using the Intel 865PE chipset, it has 8 ports at 1.1/2.0 speeds "Hi Speed USB 2.0" ( 480Mbit/s, 60Mbyte/s ) although the best real device in 2006 was only able to use 30Mbyte/s.

USB 2.0 ports can use older USB standards. Most new motherboards out now support USB 1.1/2.0. Most USB SSD devices use the 2.0 standard.

USB 1.1 quickly replaced 1.0, Few 1.0 devices actually made it to market. USB 1.1 Fixed problems identified in 1.0 and was earliest revision to be widely adopted. Most Keyboards/Mice etc use 1.1 Standard.

You also did not mention which Belkin 4 port hub you have. If your hub does not have "transaction translator" then it means each port only gets 1/4 of the speed of 1.1/2.0. But if it does have it then each port is capable of full speed ( but the total combination of the 4 hubs cannot exceed USB 1.1/2.0 specs )





I believe your problem is because your Hub dose not have "transaction translator" which slows down each of the 4 ports on it.

Also the reason your Mouse's are only reading low speeds is because they only use the 1.1 standard. All the ports on the back of your PC are capable of 1.1/2.0.

Thanks Pryde,

My Belkin doesn't have "transaction translator." I didn't even know enough to look for one with that feature.

My antique MS Office Keybaord is 1.0 USB so I unplugged it from the 4-port hub and plugged it directly into a 2.0 port on the back of the PC and I haven't gotten that message again.
