I am having a problem with my USB zigbee dongle , TI cc2531 that I bought from ebay and home assistant
I set up zigbee2mqtt addon using instructions. The cc2531 was already flashed.
the failure used to happen sometime after my Raspberry Pi 4-based HA was turned on. initially the green(led2) one would be blinking and the red led (led1) would be fully lit, after some time I noticed the led’s would be turned off. and I would see sth like the following in HA logs

on the host kernel logs.
Right now, it has a solid red led, probably because I reset it.
Any suggestions?
I could upgrade to a more dependable zigbee usb dongle if that would help
