videobruce Posted August 10, 2006 Share Posted August 10, 2006 Using a USB leyboard with a PS2 adapter (not to tie up a USB port), the system doesn't reconize the keyboard. It does with a USB mouse using a PS2 adapter. It is a Compaq keyboard if that matters.I will try the keyboard on another box when I can and try the other adapter also. In the mean time any ideas?

videobruce Posted August 10, 2006 Author Share Posted August 10, 2006 Because it is a USB keyboard or because it is a Comtrash USB keybord? Or could it be a bios issue on the MB? Link to comment Share on other sites More sharing options...
ripken204 Posted August 10, 2006 Share Posted August 10, 2006 just b/c its usb. i have a great bios so i dont think its that, unless theres some unknow option. Link to comment Share on other sites More sharing options...
jroc Posted August 10, 2006 Share Posted August 10, 2006 (edited) I have a Logitech USB..that I use with the PS/2....are you sure you have the keyboard drivers for PS/2 installed....and yes the bio's could be checked also for 'keyboard' detect and PS/2 enabled.

videobruce Posted August 10, 2006 Author Share Posted August 10, 2006 It reconizes the USB mouse (with a adapter) in the PS2 port ok. Link to comment Share on other sites More sharing options...

puntoMX Posted August 10, 2006 Share Posted August 10, 2006 It´s the chip inside the keyboard that doesn´t work with USB, some mice also have the same thing.For 90% a PS/2 to USB adapter doesn´t work if it doesn´t come with the input-devices.

LLXX Posted August 10, 2006 Share Posted August 10, 2006 The "adapter" doesn't really have any circuitry in it, it just changes the pinout.Most mice now are dual-mode, they can sense which mode to operate in (USB or PS/2) depending on which port it's plugged into.Keyboards. I don't know of any dual-mode ones. Link to comment Share on other sites More sharing options...
ripken204 Posted August 11, 2006 Share Posted August 11, 2006 okay, good stuff to know guys, thx. Link to comment Share on other sites More sharing options...
puntoMX Posted August 11, 2006 Share Posted August 11, 2006 Keyboards. I don't know of any dual-mode ones.Logitech for example has them like almost 10 years or so now, green for the mouse, purple for the keyboard, like the color code of the motherboards, I think the colors are from 1997 or so...

gamehead200 Posted August 11, 2006 Share Posted August 11, 2006 PS/2 mice and keyboards have different pinouts... That's why you can only plug them into their specified ports on the back of your computer. Same goes for those little PS/2 adapters. There are ones made specifically for mice (green) and ones made specifically for keyboards (purple/blue)! Link to comment Share on other sites More sharing options...
videobruce Posted August 11, 2006 Author Share Posted August 11, 2006 Thanks for the input. This isn't my system or I wouldn't have a USB keyboard in the first place............ Link to comment Share on other sites More sharing options...
videobruce Posted August 11, 2006 Author Share Posted August 11, 2006 and ones made specifically for keyboards (purple/blue)! You have seen violet adapters? I was told there are only the green (mouse) versions. Link to comment Share on other sites More sharing options...
