I don't know whether someone needs help with this or not anymore,
however I had a similar problem with a Mustek
848 LCD UPS and the solution was easier than I thought: there was no
need to load the cypress_m8 module,
because, at least on the systems that I've tried (Ubuntu 12.04 and an
Openwrt i386 build), using the blazer_usb
module, the first serial console was being used to communicate with
the UPS and there was no /dev/ttyUSB* present.

My lsusb:

Bus 001 Device 038: ID 0665:5161 Cypress Semiconductor USB to Serial


My /etc/nut/ups.conf:

[mustek]
        driver = blazer_usb
        port = /dev/ttyS0


And, after I successfully started upsd and the driver, the output from
upscmd -l mustek:

Instant commands supported on UPS [mustek]:

beeper.toggle - Toggle the UPS beeper
load.off - Turn off the load immediately
load.on - Turn on the load immediately
shutdown.return - Turn off the load and return when power is back
shutdown.stayoff - Turn off the load and remain off
shutdown.stop - Stop a shutdown in progress
test.battery.start - Start a battery test
test.battery.start.deep - Start a deep battery test
test.battery.start.quick - Start a quick battery test
test.battery.stop - Stop the battery test

Cheers,
Stefan

Slight correction: "port" can be set to anything for the USB-based NUT
drivers (it is ignored in the driver, but other parts of NUT need some non-empty
value for it), so the statement "the first serial console was being used to
communicate with the UPS" does not follow.

Does the output from "upsc mustek" look reasonable?

Thanks for the report,
