Updating Firmware of ASI120MC

[ZiHao]

Recently I bought a new laptop and two of the USB ports are 3.0 therefore it is not compatible with my USB2.0 ASI120MC without updating the camera's firmware. I am worried that after updating it, does it affect the performance of guiding very much? And do I update my camera using another device that has USB2.0 port? Thanks a lot.

Hi. I have a laptop with both usb 2 and 3. Never had an issue with my ASI120 on either? Also, with my ASI1600 which is USB3 it works no probs on USB2. Even the USB hub on the ASI1600 is only USB2 and the 120 is plugged into that. What makes you think you need to update it?

I can't connect it to PHD2, Sharpcap as well, All the drivers installed, from the device manager it says :

This device cannot start. (Code 10)

Insufficient system resources exist to complete the API.

Have you tried a different PC just to rule out the camera? Like I said, I've not had any issues myself. Perhaps an email to ZWO if you can't solve it?

The another laptop works fine, but that is not mine, so it would be more convenient to use this laptop for imaging.

Laptop issue it is then. I thought all USB3 was backwards compatible with 2.0. Not the case it seems. Hope you get it resolved. Please post back up if you do.

FYI

The USB 3.1 standard is backward compatible with USB 3.0 and USB 2.0.

So, the camera should work on the USB 3 port.

Problem solved. Eventually I have to update the firmware of the camera after trying multiple solutions. I heard that the original version is more stable, the latest one will somehow lower the frame rate, I am not sure. Anyone has any experience with this?

Hi may I get some help updating the firmware? The firmware updated doesn’t scan my camera

This is from ZWO. Hope it helps.

Can anyone help with a copy of the ASI120MC-compatible.iic file?

It doesn't seem to be on the ZWO website and the firmware updater just opens a folder on my computer.
