Ps2 mouse not working on one system

If you are trying to convert your Logitech Trackman Marble FX from PS2 to USB so it will work with Windows 7, you can't just convert the port type - you have to get an "adapter" that converts the PS2 signal to a USB signal. See for ATen - UC 100KMA. WEB SIte:
http://www.aten.com/products/KVM/KVM-Modules-&-Accessories/PS2-to-USB-Adapter~UC100KMA.html#.U5sYrCi4NAE.

It allows you to convert a PS2 keyboard and PS2 mouse/trackball with the one device. It's what I use and it works just fine. The regular $2.00 port adapter was useless.

They are on EBAY sometimes for $20 or so. GOOD LUCK. :)

usb to ps2 converter, the sell them for like 30$ but you can go to radioshack and buy a keyboard for that with the little adapter

i don't ?

Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.

It seems that you KVM switch is not working properly. computers connected to a KVM switch are not dependent to each other. you should be able to work on any of your computers while the others were turned off.

so is the KVM (control side, PS2 mouse / kbd>??)
or are all PS2 ports wired to adaptors,? i cant guess this nor what was used before, no history stated.
what was there before, this act?
and what now?
Ill assume worse cases (tossed a coin)
18 (16+2) adapters now. all devices are USB but KVM
ok.?


what mode fails, both the KVM pushbotton switch and or the hot key commands on the kbd?
Oops no manual button as seen on modern KVM.

KVMs are very complex. the hard part is the vast number of different PC.
USB , PS2, VGA, DVI and HDMI.. yah,..
OK 16 +2=18 x ps2, and 9 VGA ports. it is.
NO KVM does it all, ,, old KVM' do NOT work , on new computers, all folks know this , if they tried. or took readings to learn why it fails.
I bet power to the KVM is dead., no LED./
no manual button ,oops.
pin 4 PS2 reads 5vdc and connected up, same?
we use breakout boxes (DIY) to test ports connected.'

that Compaq is very old and no support now, no books.
why not ask at real HP, maybe some old guy there can dig it lost books>
40 KVM? that what you said, really? (or 40/8=5 kvm)?
my guess is the adaptor does not work or power issues
KVM >>PS2>>>ADapt>>> USB.(server) (usb 1,2,or 3 at server?)
The KVM in most cases, here, steals power from PS2 ports but not this KVM , its better.
i'd bet that adaptor cant do that.
(is the caps lock key working on the KBD and laser LED glowing on said mouse?

ask here, real HP.
lets see tests:
1: pin 4 ps2 5vdc?
2: mouse glows?
3: keyboard led , caps lock toggles? (glows)
4: lost the hot key commands (y/n)

one other problem is the BIOS in the server may not like your adaptor at all. When BIOS scans the keyboard. it expects a ID response if missing or grabled, it drops that device port.

btw, one way to cure this, is run headless server software
end KVM for ever.

i run a LAMP server, that comes in the box, no kvm no any thing on ports. it has a web page to go to and do service that way.
port IP+:12321
modern ways work best.
in a server farm, a keyboard/mouse/monitor on rolling cart
for the super sick servers is best...

the other problem is USB only PC or server
does not scan PS2 ports, it has none
so if the adaption fails, at boot time, all is lost.
(BIOS reports connected devices to the OS)(unstated by you)so if the report fails, problems happen
for sure after the boot.

this device is s business device, now ("Enterprise)
the posts on it are like 10 years ago. all links to books now dead.
infact the compaq server that had them is turned off. (grin)
here is my search there. Why not ask them?

Solution for the mouse. I have 8 KVM's. Most of my computers work with the KVMs. On 1 inland KVM the logitect and Microsoft optical mice do not work on one computer (but work with the other computers). They both are USB. I hook them up with a USB to PS2 adapter. If I use a ps2 ball mouse connected to the KVM the mouse works. All the Mice work if I directly connect them. Since I do not want a ball mouse I got a Frisby optical PS2 mouse. It works with all the computers on the KVM's.

I do not have a solution for the Keyboard yet. 1 computer (ASUS MB) on my trendnet or belkin 4 postion KVM does not recognize the keyboard.

I have similar problem. 2 inland KVM's (both have PS2 inputs, one has USB outputs) do not light or recognize my usb mouse with a PS2 adapter. They do recognize a PS2 ball mouse on the KVM's however. One of the computers (Sony vaio 1.5 GHz) does recognize a usb mouse with adapter on 2 other KVM's (Old Belkin and a Trendnet) (the second computer I have not tried in those configurations). Next I will try an optical mouse with a PS2 fitting. That did work with a fifth KVM at an auto business last week.

If you have the PS2 mouse and keyboard (round plug-in) instead of USB this is an easy install. however if you have USB you will need adapters to make this work, but I do not recommend it since more problems could occur. If you have the PS2 ends first shutdown both computers. remove your monitor, mouse, and keyboard from your computer and attach them to the single end of the switch. Mouse goes to Green, Keyboard to Purple. Take the other ends and connect the first group to your first computer mouse, keyboard, and monitor (same colors as above) and repeat for 2nd group of wires on 2nd computer. turn the computers on. you should get display, keyboard, and mouse for 1st computer. after both boot hit scroll lock 2 times within 2 seconds and then arrow up or down key to change between computers.

I?ve had issues with USB mice on the more inexpensive KVM switches. I?m currently using a Belkin OmniView using a Microsoft Explorer USB optical mouse and a PS2 to USB adaptor. The adaptors I use are from Cyberguys.com and work well for most of the USB mice we have.
