I have just tested this kind of dual USB setup on Windows XP and it
works with latest SVN. That is to say I managed to run 2 usbhid-ups
drivers at the same time connected to 2 different UPS.
It doesn't work with NUT's site binaries because of a bug in regex which
crash the driver.

What version of NUT are you using ?
Have you compiled your own binaries ?
What Windows version are you using.

While trying to mimic your ups.conf I found that you should add
whitespace around the '=' sign in the conf file: you should use
"serial = AS1026662626"
rather than
"serial=AS1026662626".
This is a bug in Windows version, I will check.

Regards,
Fred
