Hi I have met strange behavior, during configuration home cloud.
In case I connect SSD drive (Intel 660p) via USB and mount it, after some time console time-to-time freeze on some commands(especially df, look up filesystem by MC).
Also once per few days station not responding at all.
Does someone detected similar issue?
What is power limitation for connected USB-devices?
Now I’ve connected SSD by NVME adapter, and I will continue observe this topic.
You can login by ssh and check the kernel dmesg if there is anything unusual.
Wikipedia says that USB3 devices can draw upto 900mA current at 5V, ie, 4.5W. Dont know if this has been changed by Radxa team. Which power supply are you using?
Besides power supply, the issue may also be with the Usb storage kernel driver. Checking dmesg and /var/log/syslog when the freeze happens is a good idea as suggested.
Edit-
I have searched online, and NVME drives can draw much more power at peak load than a USB3 port can supply. So connecting it via the NVME adapter seems correct.
For ROCK Pi 4 USB current output limit:
The USB OTG has one dedicated current limit control which is 1.45A.
The other USB 3.0 and the two USB 2.0 share a current limit control of 3A together.
In dmesg I don’t see anything suspicious, but could I just don’t know what to search for.

@jack This bug really easy reproducible with my rockpi. In case I can enable additional logging, just point me to correct config/command.
During period when terminal freeze happens, there not present anything in logs, here just when I connect SSD to RockPi via USB:

@jack Now I got this as usual base bug.
Looks something similar to https://forum.pine64.org/showthread.php?tid=5832
But even with blacklisted uas I got same behavior.
So question if it’s HW limitation in my rockpi, or could be some-how managed.
