It might be helpful to set
sysctl -w kern.module.verbose=1
to confirm this possibility.
I don't know if I can confirm this possibility.
I have removed usbverbose from kernel: modunload usbverbose.
No error. Just after, I have set kern.module.verbose=1
When I start bacula job (and stop to avoid panic...), I obtain on console :
