Well, but this time, it succeeded in setting up debugWIRE mode:

OK
So it appears your ATtiny44 is already fused for debugWIRE mode. In
that case, the command you issued (temporarily, until the next power
cycle) returned it to ISP mode. Issuing
avrdude -p t44 -c dragon_isp -P usb -U hfuse:w:0xdf:m
as the next command should permanently disable the DWEN fuse again.

Never trust an operating system you don't have sources for. ;-)
