OT USB to PS/2 adapters

[Mark Jarvis]

I have a relatively new (<1yr) PC without PS/2 keyboard & mouse 
connectors. I've accumulated 4 USB to PS/2 adapters. Three are just 6" 
cables with a USB male on one end and a PS/2 female on the other. The 
fourth is similar, but has a large oval-ish thing in the middle of the 
cable. My MS ergonomic keyboard has a PS/2 connector and will not work 
when connected using one of the three plain adapters, but will with the 
fourth.


I'd like to understand a) why, and b) where to buy a couple more of the 
adapters that do work (for another project).


Any help from the incredibly knowledgeable PLUG-ers will be gratefully 
appreciated.


Thanks in advance,
Mark Jarvis

I've had that same experience with ps2 to usb adaptors; It seems the more
expensive ones work better (electronics in the middle) but it's hit or
miss.  I've gradually phased PS2 devices out in favor of usb devices.

It has to do with the specifications between USB 1.0 and 2.0 which require
different power where the cables must also contain that capacity.

A corollary to RTFM is Look at the Stupid Device. It had Radio Shack
molded into the front and even had a part #. on the back. Duh!

I was setting up my wife's new box and of course had the same issue
there, so I got on my horse & got myself over to Radio Shack.
The durn thing cost $20, but now everything works!

The USB 1 vs USB 2 makes sense. I'm pretty sure that I'd
successfully used those simple adapters sometime in the past, but
everything's USB 2 now, going to 3.
