[BRLTTY] brltty no longer starting correctly

[John Covici]

Hi.  All of a sudden, I cannot get brltty to start.  I am using a
Humanware Brailliant bi 40 on brltty 6.2 and kernel 5.4.69.  The
relevant lines  from the log file are:

Jan 29 16:06:10 ccs.covici.com kernel: usb 1-10.4: reset full-speed
USB device number 10 using xhci_hcd
Jan 29 16:06:11 ccs.covici.com kernel: cdc_acm 1-10.4:1.0: ttyACM0:
USB ACM device

Jan 29 16:06:11 ccs.covici.com brltty[2246819]: USB interface in use:

Jan 29 16:06:11 ccs.covici.com kernel: usb 1-10.4: usbfs: interface 0
claimed by cdc_acm while 'brltty' sets config #1

There are no other brltty processes running.

How to fix?

Thanks.
