notice also than the plug is not identical to usb2 one, so you will also have to change the front device
I'm aware of the "double" format https://upload.wikimedia.org/wikipedia/commons/thumb/c/c3/Connector_USB_3_IM... I have that on my 12" Samsung tablet. But that's just one of many USB3 formats. Wikipedia makes it clear that First: "A USB 3.0 Standard-A receptacle accepts either a USB 3.0 Standard-A plug or a USB 2.0 Standard-A plug. Conversely, it is possible to plug a USB 3.0 Standard-A plug into a USB 2.0 Standard-A receptacle. Similar principle of backward compatibility applies to connecting a USB 2.0 Standard-A plug into a USB 3.0 Standard-A receptacle. The Standard-A is used for connecting to a computer port, at the host side." However Secondly: "A USB 3.0 Standard-B receptacle accepts either a USB 3.0 Standard-B plug or a USB 2.0 Standard-B plug. Backward compatibility applies to connecting a USB 2.0 Standard-B plug into a USB 3.0 Standard-B receptacle. However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. The Standard-B is used at the device side." The key thing is that, apart from that new "double" format: "Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, ..." There should be colour coding indicating the difference. Now what exactly are you talking about? Right now I am using my USB3 SDXC adapter in q USB2 socket and seeing a fantastic speed improvement over one 'fee' one I got with one of those 32G-that-was-really-only-8g chips. I don't have a USB disk drive or USB DVD. A new box or mobo looks attractive for reasons of simplification as well. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
