It is *very* unlikely that this is going to work. The 'lakeview' driver is
essentially for a contact-closure-over-USB interface.

As far as I know, the Mustek Powermust 600VA uses the Megatec protocol
over USB. The fact that it is reported to work with the 'megatec' driver
on the RS232 interface is also a strong indication for that. In that case,
the 'megatec_usb' driver would be appropriate. Unfortunately, neither the
'agiler' nor 'krauler' subdrivers appear to work for this device (search
the archives for this), so we probably need to write a third subdriver. If
you're willing to work with us, we might do that.

Another, much easier way, is to use a serial-to-USB converter that can be
bought for around € 10 nowadays. This will provide your system with a
serial interface, so that you can use the RS232 interface with the
'megatec' driver.

Best regards, Arjen
