"This device can perform faster"

Reciprocate · 22 Nov 2010

Hi, I receive the notification in the taskbar below whenever I turn on my USB 3.0 externals. I didn't get this when I first used these externals, this has only happened more recently, and happens with both the Vantec and Eagle Tech USB 3.0 enclosures I have.

FYI:

I'm using proper USB 3.0 cables.
The USB 3.0 cables are plugged into the USB 3.0 ports in the Kingwin U3PCI-1 PCI-e adapter card I have, properly.
They are not loose.
I'm using Windows 7 Home Premium 64

Hi Reciprocate, welcome to the Seven Forums.

I've had the same message with an older external HD, reason being that HD was only USB 2. It's not logical (USB 2 device can not perform faster when connected to USB 3 port) but that clearly was the reason in my case. Could this be your case?

Kari

EDIT: Sorry, that is wrong info I gave here. I realized it my problem was with really old USB 1 device and USB 2 cable & port... The message was the same, though.

It may be a stupid question - but I have to ask if you have the latest drivers for the PCI-E card?

Although I don't have USB3, I sometimes have the same issue with USB2 and memory sticks that I know are USB2 compliant. For some reason, the speed capabilities of the device aren't being picked up correctly when inserted. This doesn't always happen, but when it does I find that in most cases simply unplugging and reinserting the device causes it to be recognised correctly. It should be pointed out that this doesn't affect the functionality of the device in any way - it still functions as intended, though not at higher speed.

Yeah I have the current drivers from the site (the model is located here btw) and I've tried uninstalling and reinstalling them quite a few times. I guess they're the standard USB 3.0 drivers for the NEC chipset used on a lot of these cards, but they seem to be temporamental with my card and I receive the message whenever I turn on the enclosure(s).

Just a thought: USB ports work in pairs. At least with USB 1 and 2 it was so that if you had a USB 1 device connected to a USB 2 port but it's pair, port next to it was empty, you did not get this message. Of course. But if you then connected a USB 2 device to a pair where the other port had a USB 1 device connected, even though there was nothing wrong you got this message.

A bit whisky yesterday, all night up, talking (typing) gibberish. Hopefully you can understand what my point is.

haha, yeah I tried just plugging in 1 of the enclosures alone into the Kingwin adapter but I got the same message.
What is really strange though is that when I plug in separate Acomdata Samba USB 2.0 enclosure to the Kingwin port (either by itself, and/or with a USB 3.0 enclosure) I don't get the that message

. I don't know why I'd get it with a 3.0 device and not a 2.0 device. That is just weird

Do you only get the message when you plug into the front USB ports or is it with rear ports as well? For some computer cases, the wiring between the ports and the USB header on the mobo is inadequate and may not support USB 3.0.

You only get that message if you plug in a device with a higher rated speed than the USB port its plugged into.
If you plug a USB 3 device into a USB 2 port, you get that message. In this case the device will preform faster if you move it to a USB 3 port.
If you plug a USB 2 device into a USB 3 port you won't. In this case the device won't perform any faster if you move it so no warning message.
It looks like your USB 3 PCIe card is only running at USB 2 speeds.

I don't get the message if I plug a 3.0 device into any 2.0 port anywhere.
Only when I use a 3.0 device in a 3.0 port.
