I did that, but all I could find was vendor, product, serial, vendorid,
productid and bus. I was assuming that those correspond to idVendor (the
string), iProduct, iSerial, idVendor (the hex number), idProduct and Bus
in lsusb -v.

Ok, did that.

I always made sure that all instances of usbhid-ups were killed before
trying out a new configuration.

Did that too and the usbhid-ups -DD output indicated that it read the
serial number from ups.conf, so I started it via init script and it
worked. Great. Put some spaces back into ups.conf, stopped and started
everything and it still works. So I'm not really sure what I've done but
it's fixed now.
Thanks!

On a slightly related note.
Is it possible to configure two different SHUTDOWNCMDs for two different
UPSs?
