No. I am the original owner. The only thing done to the lens is the mount correction by Sigma to avoid the scratch to the K1. Please notice that the lens I have it does not contain the word MACRO in the name description and it reads HSM. Instead of HSM II. Therefore, it is a different version.

Have you changed the psu already?
I think is most likely the psu.
Second is the video card drivers which you already updated. Does this video card requires direct power from the psu? Is that Connected? Is the video card fan spinning?

As shown in the photos in the article of the original post, Sigma replaced the flange in certain lenses so it will not scratch the camera body.

I recently bought a Sigma 35 1.4 from B&H, it already came compatible.

Prior than that I have a Sigma DG 24-70 2.8 and a Sigma DG HSM 70-200 2.8 which I sent to Sigma USA and they replaced parts and made them compatible for free.

Great service from Sigma. I enjoy my Sigma lenses.

in the PC where you got an error try to connect into a different usb port. If you tried the front port, try the port in the back of the computer for example.
do not use USB extension cables.
do not force the cable into the camera usb port.
this type of usb cable is also is common also to charge phones and other devices so you may want to try a different port/different cable.
use the original pentax battery fully charged. turn on camera after cable is connected.
