Can a PS/2 port be used for USB?


I have an adapter that came with my wireless mouse that lets me use it as a PS/2 mouse by directly connecting USB to PS/2 with a small, simple adapter. If I plug something else in (e.g. a USB mass storage device like my camera) to the PS/2 port, it will be powered through USB like if I were to plug it into a real USB port.

My question is: is it (theoretically or practically) possible to use my PS/2 mouse port with this adapter as a real USB port to plug in a mass storage device?

As I said, both USB devices I plugged into the PS/2 port (one a USB mouse and the other a USB mass storage device) powered on just like they would in a USB port. On the old Compaq LTE 5100 I'm using, it interferes with the mouse and keyboard functions under both DSL Linux 3 and Debian Etch.

Some USB HIDs require power, that's why the power line is active. However, a ps/2 port does not have the same electronics behind it as a usb port. Further, the adapter you have likely only changes the shape of the plug, routing the wires to their approximate equivalents.

Any data coming from the HIDs will be interpreted as keystrokes or mouse actions since you probably have ps/2 entries set up in xorg.conf ... what you'll be doing is setting up 2 mice, only one is a UMS device.

Even if you stop the conflict, I don't see how you would mount the thing.

Okay, I thought so. Hey, at least it can be used for a USB-powered fan or shaver if I ever need to use one ;D
