Mine is NOT a DSI III, but the original Meade DSI Pro so not the same camera as you have. It have been working fine for several years, but suddenly stopped working in indi on RPI/Ubuntu 16.04. It still works fine in Windows, with the same cable. I guess the error is related to this message:
<strong>2019-03-11T19:32:38: Driver indi_dsi_ccd: terminate called after throwing an instance of 'DSI::device_read_error'
2019-03-11T19:32:38: Driver indi_dsi_ccd: what(): libusb_bulk_transfer error Operation not permitted

So SOMETHING is happening...

The error relates to device access permissions which should have been set by the udev-rule included with the driver in /etc/udev/rules.d/99-meadedsi.rules which hasn't been modified since July last year.

More specifically the mode command on these lines:
# 2. Post-renumeration IDs
# Meade DSI
SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="156c", ATTR{idProduct}=="0101", MODE="0666", SYMLINK+="deepskyimager.%n"

If you have a symlink in /dev/deepskyimager.0 (I guess it starts with 0, could be 1 too) that should have been run and if not, udev debug log might show a reason why not.

Sorry I should have been more clear, it’s the same driver used for all three cameras, and I Have Used all the DSI cameras with this driver, and just tried the DSI Pro again and that works fine on mine...so it’s clearly not the driver...I mentioned the DSI Pro III earlier as that’s the one I used last... :)

Thanks, great to know. What OS are you running?

It is odd that it just suddenly stopped to work after having worked fine for years....

ACTION=="add", ATTR{idVendor}=="156c", RUN+="/bin/sh -c '/bin/echo 256 >/sys/module/usbcore/parameters/usbfs_memory_mb'"

SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="156c", ATTR{idProduct}=="0101", MODE="0666", SYMLINK+="deepskyimager.%n"
 
pi@pi-Obs:~$ ll /dev/deepskyimager.*

Just wondering, is your DSI Pro the version 1 or 2 ....?

There are three versions of Meade DSI Cameras, I, II, III and all three are made in mono and colour, the first one is a small 1/4” sensor, the version II was a 1/2” sensor, and the III, which I have is 2/3” sensor...
So that should help work out which you have... :)
A picture of the sensor would help identify..

AppArmor change maybe? If that is running on your system, check its logs in /var/log/apparmor.log when the driver starts up.

Thanks for the suggestion. I tried to stop and disable AppArmor , but the driver still does not work.
