A USB to Ps2 adaptor is a USB-PS2 adaptor. There is no such thing as
one for mouse and one for keyb. Try swapping them and you'll probably
still ave the same problem. I imagine it's a keyb issue. your usb keyb
doesn't support ps2. i haven't experiencced that though.
--oringal response from my misreading---!! including in case somebody
find it useful
That is extroadinarily odd. I think you got it the wrong way around.
kony has provided some technical terminology that explains my
experience. I shall use this terminology.
I have a simple little USB-PS2 pin adaptor. And a simple PS2-USB
pin adaptor. And an elaborate 2*PS2 to USB adaptor
Using my USB-PS2 pin adaptor worked perfectly.
My USB mouse and keyboard plug into my ps2 socket. This is because
most or all USB devices support ps2 too. And I think they sort of
detect whether it's usb or ps2 that they are plugged into.
USing my Ps2-USB pin adaptor appeared not to work. THis is because
most ps2 devices including my own, do not support USB. THe pin
adaptors were actually ok. INfact. I tested them in the following
way. I took a USB device, converted it to PS2 (so it's like a ps2
device that supports usb). Then I used the ps2 to usb adaptor. And that
worked! So there's nothing wrong with those simple ps2-usb pin
adaptors./
I also have an elaborate 2*ps2 to usb adaptor. It's a large beast. It
has as 'bridge chip' built into it. Mine wasn't so great. It would
flash when keys were pressed or teh mouse was moved - very good. But
when it only detected once i got into windows. And it'd load a driver
caleld HCI or something human computer interface or something.
Mouse or Keyboard makes no difference. USB to ps2 is USB to ps2. Maybe
you have a weird USB keyboard that doesn't support ps2 ? I never
experiecned that. But the adaptors are blind to whether it's
mouse/keyboard plugged in. You can prove this by swapping the adaptors.
you'll find it'll make no difference.
Regarding pin adatprs. I find that my smaller ones alwas work. I have
some slightly fat ones which are stil just pin adaptors but give a "not
recognised" usb error when going into usb ports of one of my comps.
