Hi everyone. I'm facing random issues with my MI G2-8300FW, hope you can help me.
When I'm imaging (or focusing) sooner o later I start to get errors from indi_mi_ccd_usb driver ("[ERROR] Getting voltage failed: Camera is not connected. ", "[ERROR] Getting image ready failed: Camera is not connected. ", and so on). At this point the only thing I could do is shutdown the indi server and start it again.
Here is the relevant section of the log, where you can see that the driver is reporting an error on libusb_bulk_transfer failed():

I'm running indiserver and kstars/ekos (latest versions) under Ubuntu Mate 17.10 (up to date) on an Intel NUC6CAYH (BIOS up to date). USB controller seems to be using Linux 4.13.0-38-generic xhci-hcd driver.
dmesg output shows two warnings about "invalid maxpacket" upon plugging (not sure if it's related to the issue):
--- inmediately after I plugged the camera: ---

Tests I've done:
- Changed the usb cable. Same result.
- Tested the camera (with original cable) in a windows box. No issues found (tested through six hours of continuous shooting).
I didn't experience any of these problems before on my previous astro box, which was based on a RPi3 but I was running earlier versions of indi and moravian driver.
Any ideas? Thanks in advance.
