Canon 40D -ASIAIR -Exposure Failure?

Hi. Ive connected my new ASIAIR to my ZWO ASI 120MM - Mini guider and all works fine on the Guiding side. I've also attached as the main camera, and works okay. I've also attached a ZWO ASI 120MC-S as the main camera, and seems to work fine.

HEQ5 Pro with EQMOD also doing good.

I'm having problems with my Canon 40D though.

Camera connects okay as Canon 40D (PTP mode?) with all the required RAW, Bulb, L etc. settings. When in focus or Preview mode takes 1 or 2 images, then comes up with 'exposure failure'. Unable to get any files to load in 'Autorun' either, as same error message appears. Camera works fine on Backyard EOS.

Any ideas?
