Thank you Jasem! That worked. I looked at the cpuinfo file, but it was empty. I may be looking in the wrong location.

Hi,
Same problem with rpi4 model B rev 1.4 (8gb).
Restoring USB functionality works. Thanks Jasem!

Regards

So the odd thing is that I cannot reproduce this reliably... I even tested on the 8GB version (rev 1.4) and the USB stuff worked there.

So I got hit with this tonight. It happened after I updated my Raspbian to the latest, by doing "sudo apt update" and "sudo apt upgrade". It just so happens I had a backup image from only a week ago, so I was able to revert with minimal loss.

This is on my Raspberry Pi 4 with 4GB RAM.

As requested, here are the last 4 lines of /proc/cpuinfo:

Hardware : BCM2835
Revision : c03111
Serial : 1000000089f01859
Model : Raspberry Pi 4 Model B Rev 1.1

This is mine, also 4GB:

On the RPI4 with USB issues:
Yours is v1.1 but the SoC is BCM2835?? how come? Could this actually be one issue? The Rev 1.2 here exhibits the issue, but it appears the SoC is detected correctly at least.

How come? I have no idea.

Since this might actually be a permissions issue, I wonder if running indiserver as root would help? I've already reverted, and I don't want to update to the latest just to test this theory.

Yes running as root works, but this is not really a solution. Something is broken.

Of course I didn't mean it as a permanent solution, but rather a troubleshooting step, to see if it really is a permissions issue with the new update.

Jasem,

Are you using a USB hub? I only had this problem when using a powered USB3 hub. If I unplugged the hub, and plugged my devices into the Pi directly, the problem went away.

Since the skies are cloudy and I'm bored, I updated my system again to the latest, with the 5.4 kernel. I can confirm that running indiserver as root does indeed allow things to work again. I know this is not a fix, but at least it allows us to get up and running with the latest release of Raspbian, while we figure out what the problem is.

I posted a message on the Raspbian forum, we'll see if they can offer some help.

In fact, I am using an external powered USB hub with the unit giving me the trouble! You got a link to the forum post?

The powered USB3.0 hub is definitely in the mix. This is one thread www.indilib.org/forum/astroberry/7379-us...day-s-upgrading.html and possibly this www.indilib.org/forum/astroberry/7371-ho...astroberry-rpi4.html

Thanks Ed! I was actually asking about the raspbian forum link... If we gather enough info, we can file an issue on the Raspberry Pi Linux github.
