Now I'm trying to get it working with USB (the UPS has both and it's
getting harder to find machines with serial ports) - if it works with
*blazer_ser*, should it also work with *blazer_usb*?
When I plug the USB in, 'dmesg' shows this:

and */dev/usb/hiddev0* appears.
So I tried with this:
[myups]
driver = blazer_usb
port = /dev/usb/hiddev0
desc = "Local UPS"
*/usr/lib/ups/driver/blazer_usb -a myups*
Network UPS Tools - Megatec/Q1 protocol USB driver 0.03 (2.6.0)
libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied.
libusb requires write access to USB device nodes.
libusb couldn't open USB device /dev/bus/usb/002/001: Permission denied.
libusb requires write access to USB device nodes.
libusb couldn't open USB device /dev/bus/usb/003/001: Permission denied.
libusb requires write access to USB device nodes.
libusb couldn't open USB device /dev/bus/usb/004/001: Permission denied.
libusb requires write access to USB device nodes.
No supported UPS detected
and */dev/usb/hiddev0* disappears.
I added the following to '/etc/udev/rules.d/52-nut-usbups.rules':
# GE EP series
ATTR{idVendor}=="14f0", ATTR{idProduct}=="00c9", MODE="664", GROUP="daemon"
I also edited the 'blazer_usb.c' file and added this:
{ USB_DEVICE(0x14f0, 0x00c9), &krauler_subdriver }, /* GE EP
series */
(also tried other subdrivers - cypress, ippon, ...).
I also manually change permissions on '/dev/bus/usb/*/*' to 666, but it
also didn't help.
Anything else to try?
