USB keyboards/mice

[SnoMunke]

Since most keyboards/mice run on USB 1.1, wouldn't using them versus PS/2 slow down a USB 2.0?

Huh?

USB by architecture is serial (hence the "S" in the name) and will only run as fast as the slowest devices plugged in. Therefore, if you have a high-speed USB 2.0 device (480 Mbits/sec)(such as an external HDD) and are using a USB 1.1 mouse (12Mbits/sec), the HDD will only run at USB 1.1 speed.

Is my thinking correct?

If they are on the same usb root hub thats correct, general each 2 ports on your rear pannel is a seperate usb 2.0 root hub that supports the full speed of the bus so unless your mouse and hdd are on the same root hub they shouldn't effect each other, but you are correct in that all devices on the same root hub function at the same speed (ie the speed of the slowest device in the chain)

I wonder how many people pay attention to this....
