Re: Advice for a PS/2 to USB splitter device

Hi to all

After a LOOONG while, I bit another bullet and this splitter device works great! Unfortunately, it's one of those unknown brand types.

I decided to take a look at the VID of the device.
In winxp, go to device manager, HID keyboard device, Details tab.
The good one had a VID of 4b4 - Cypress - a well known USB vendor.
The bad one was a D3D - Tangtop - never heard of before.

So if you can try out the device, moral of the story - go with a known name brand.

There's a list of usb vendors at:

Happy New Year!

Hello to all
If this is the wrong forum, I would appreciate a redirection.

With new laptops sporting USB only ports, I hooked up my PS/2 ergonomic
mouse and keypad to a single USB port via one those el cheapo splitters.
Costs about US$7.

Every now and then, the mouse and keypad will hang, so I have to unplug
and plug the device to reset it. Very troublesome of course. The shop
says I should buy ths US$30 version.

Any help is much appreciated.

Thanks, 


could be a prob with usb port. could be a prob with ps2-usb adaptor.
may even be a windows issue.

you could get the $30 thing, but there's no guarantee that it'll work
and I doubt the shop would refund you. so you could then resel it on
ebay if it doesn't help.

you could get an ergonomic usb keyb/mouse

I have foudn that some cheap ps2-usb adaptors don't work at all. Other
cheap ones do.  The little red ones I have work very well. The slightly
larger green ones do not. I get "unrecognised device"

See, in my case, with the cheap ps2-usb adaptors, I never got a
situation where it worked and then stopped. I got cases where it wasn't
recognised at all.

Most ps2 devices won't work at all with the cheap ps2-usb devices.  ps2
typically doesn't recognise usb. (though usb recognises ps2) so cheap
usb-ps2 works. though in your case it works then stops. So you must
have a special ps2 device that recognises usb.


Those 'beasts' with 2 ps2 ports and one usb port. They are detected by
windows with their own chunky driver. "human computer interface". So
it's not like plugging in a usb keyb and mouse.  I don't recall being
able to get to the bios with it. It needed windows drivers.
