If you're using my repo then most likely you already have latest version of everything including INDI SX driver.

It is indi library 1.0
I tried it again today. lsusb recognizes the camera. The indiserver connects to the camera without errors and everything looks to be working in Ekos.

I don't get any error messages it just never downloads an image.

I tried capturing an image from the command line too and the log just hangs at read.

One thing to note is that the driver recognizes the camera as SXVR-H36 when it is actually an SXVF-36. Could this be a problem?

I also have failed completely to get my Orion ssag working in ekos. I thought that it was supported by the QHY drivers?

Thanks.

What's the VID:PID for both SXVR-H36 and SSAG?

When looking at the code in the trunk, I see that the sleep was commented out, but 'libusb_bulk_transfer' is still trying to download the data in one single chunk.

For me (with the H18 camera), it worked when reading in chunks smaller than about 15MB, otherwise libusb gives some strange error.

This is the code you sent me earlier. I played a little bit with the chunk size to see how large chunks I could read before it gave error. Above 15 gave error. I recommend setting 10MB to be safe.
In sxReadPixels function

OK, I'll change it that way. Peter

I will check and let you know later today.

Thank you.

Done. CHUNK_SIZE set to 10MB. Peter

Does this mean that I should reinstall the SX driver and try it again?
Thanks.

If you are using ppa:mutlaqja/ppa you may need to wait a couple of hours until it gets rebuild and then reinstall. If you are building it from source, you can checkout and rebuild it anytime. Peter

Thank You. That fixed the problem. The image downloads now.

The SX camera is working now.

dmesg shows this when the Orion SSAG is plugged in
[ 718.676226] usb 1-3: new high-speed USB device number 5 using ehci-pci

lsusb gives

I hope this is of some help.
Let me know if there is anything other info I can give you.

Thanks.

I can also confirm that the new version is working with my H18.
