/dev/ttyUSB0 device not responding


I have just re-flashed Buster and installed Build-a-pi.  flrig can't configure the USB port with  error  "Transceiver is not responding"

I tried flrig on the laptop and all is OK.
ls -sal *USB*
0 crw-rw---- 1 root dialout 188, 0 Sep  7 10:10 ttyUSB0

pi is a member of dialout group.  I've never seen this behaviour before.
