如果说鼠标用usb是传输速度快 那键盘有必要用usb吗?
还有无限鼠标和键盘的传输速度和usb比谁快?(再无线的电量充足的情况下)

其实鼠标和键盘一类的对传输速度要求很低,ps2和usb看不出什么区别,只是usb的方便一些。还有无线的不是很好用,尤其是打游戏,有的时候反应不是很灵敏。

用USB接口会更多占用系统资源,所以我从来不用USB接口的鼠标。

If you have the convertor from ps2 to serial. I suggest you use serial port for mouse and key board. More stable.

Thank you for writing back.

From your reply, I gather that you would like to know if there is any difference in performance when the mouse is plugged to the USB and the PS/2 ports.

Let me assure you that in most cases, there would not be a performance difference. In the former, the mouse works as a USB mouse and in the latter the mouse is recognized as a PS/2 mouse.

However when the mouse is used on a Laptop, it is recommended that the mouse be plugged to the USB ports. The reason that is that, when the mouse uses the PS/2 port then there might be conflicts with internal pointing devices on the Laptop; as they also use the PS/2 bus for communication.

I hope this information helps. Please feel free to write back in case you need additional clarifications on this issue. It will be my pleasure to be of assistance.

Best Regards,

Abraham

胡说八道。

试试看死机的时候,USB鼠标肯定动不了了,PS/2一般都还能动。
还有机器运行大程序的时候,USB鼠标会明显脱不动,PS/2的就不会。

Thank you for using Logitech's Electronic Technical Support. My name is Rohit. The following information addresses your original question. You may wish to print this out and/or save this on your computer.

We would like to inform you that if when you plug in your mouse in the USB port the Windows OS will automatically detect the mouse and you can start using it. If you plug in your mouse in a PS2 port the Windows OS will not detect the mouse. For the Windows OS to detect your mouse you will have to restart your computer.
The performance of the mouse will be the same whether you use it on a PS2 port or USB port.

If you have additional technical questions regarding this issue, please reply to this email.

If you have questions regarding another issue with your product, or questions regarding another product, please visit our web site at www.logitech.com and submit your question.


Thank you for your interest in Logitech.


Regards,
