It's not responding to the programmer at all in avr studio.
avrisp attiny44
mosi -- - mosi
miso ---- miso
sck ---- usck
reset ---- reset
Or can it not be programmed by an mk2? I assumed all chips can be programmed by it

The AVRISP mkII can program the tiny44 in the latest version of AVR Studio (4.18 SP3 or 5 beta). Make sure your version is either up-to-date or check the help files/release notes that came with it to verify. Also allow AVR Studio to update the firmware in your AVRISP mkII if it needs to.
Verify the following conditions:
- Programmer is connected to PCB (GND, RESET, MOSI, MISO, and SCK)
- Target is powered.
- Not sure how much power the AVRISP MKII can provide, but don't rely on it if your board takes more than 50 mA.
- You do not need to connect the programmer's VCC line to the chip power if you provide it externally.
- MOSI, MISO, SCK have pullups to GND/VCC no stronger than 820 Ω.
- RESET pullup should be no stronger than 4.7 kΩ and have a decoupling capacitor less than 10 µF.
Follow the troubleshooting guide in the AVRISP mkII user guide [PDF] if you experience problems as a first step:

1\$\begingroup\$ I was told the vcc and gnd is used as detecting the logic level am using. It doesn't provide power. is that not true \$\endgroup\$ – Ageis Mar 27 '11 at 14:05
