Timeout on USB devices...

I use some USB3 devices (RDXes) for backup, using vchanger scripts;
sometimes but too frequently i catch:

 Dec 13 20:10:09 pspve3 bacula-sd[60485]: pspve3-sd: record_write.c:232-31759 Got write_block_to_dev error on device "RDXStorage0" (/var/spool/vchanger/PSPVE3RDX/0). Error sending Volume info to Director.
 Dec 13 20:10:17 pspve3 bacula-fd[33337]: pspve3-fd: backup.c:843-31759 Network send error to SD. ERR=Connection reset by peer

Initially i suppose that was a 'network bound' trouble, but seems to me a
'io bound'; firstly i check that there's no other IO happening, and seems
yes.

Seems to me that bacula sd 'do something' (re-red some info) on volume as
director request, but timeout on that.


As for 'network timeout', there' some 'io timout knob'?


Thanks.
