Seems like your USBasp's default ISP clock is too fast. A
new device requires an ISP clock less than 250 kHz, as its
default CPU clock is 1 MHz.
Try option -B10, resulting in approximately 100 kHz. (I think
USBasp now accepts the -B option.)

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