You might want to consider a simple modification that reduces the current

It requests MaxPower 100mA, which is a bit less
than clickykeyboards
claims a Model M actually uses -- but I know the machine I'm using it on
doesn't enforce the USB power requirements anyway, so it should be safe
up to half an amp...
Thanks!
Hmm - I wonder if I can disconnect the +5V line at the keyboard and supply
+5V elsewhere (maybe just tap from the machine's +5V direct), just to try
that for a while and see if the problem goes away (it had occurred to me that
it might be an over-current issue).
I'm not sure if the adapter relies on seeing a current draw (implying a
connected keyboard) for it to function correctly, though...
