Great timing, I just started looking into this too....

I think we can split the research into two sections:
1) Plug in and enumeration
2) Image capture

Plug in and enumeration would be where firmware upload, if it does it, would occur. I'm not sure if the USB sniffing tools I have can do this. Can anyone else get a dump during this phase?

I've created a dump, of image capture, using Wireshark Version 2.2.0 (v2.2.0-0-g5368c50 from master-2.2) and the bundled version of USBPcapCMD (1.1.0.0-g794bf26-5).
It consists of starting MaximDL, capturing a 5 second frame, and then closing MaximDL.

I've configured the fan speed to be low. When the camera is plugged into USB, the fan stays high until the MaximDL software is started. It's a nice indicator of important USB activity.

I've attached the dump here, but if that doesn't work you can download from Dropbox: www.dropbox.com/s/tj2l2m873sf6e1g/sspro-...photo.pcapng.xz?dl=0

Are we talking about the same camera? I wasn't aware that the DSCI II had a controllable fan. Anyway, I pretty much abandoned working on the driver since INDI Server for Windows gave me access to the ASCOM driver for the camera.
I do have a firmware dump for the DSCI II camera but was never really clear on if I could freely post it here.

Ah, maybe not. I have the Starshoot Pro V2.0 Deep Space Color.

Good to hear that you got yours working. I'll keep chugging away and see if I can make any more progress with mine.

I really want my camera to work under Linux. I tried Windows on a Minnowboard MAX, but it decided not to boot one night, and I didn't like having to lug a monitor, keyboard, mouse, and inverter, 600' to my backyard to try to fix it. I ended up having to do a complete reinstall. Bleh.
