Hi,

It means a USB kernel device driver did not detach. Historically there 
has been several issues in cam/scsi where detaching the instance hangs.


Try running kgdb and backtrace all USB process treads. Look for "detach" 
keyword.


I've been thinking to maybe catch signals during the sx locking so that 
usbconfig can be CTRL-C'ed.

usbconfig just hangs

2016-04-13 Thread Matthias Apitz 

Hello,

This is on

FreeBSD c720-r292778-amd64 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r292778: Mon 
Dec 28 05:45:37 CET 2015 
root@poudriere-amd64:/usr/local/r292778/obj/usr/local/r292778/src/sys/GENERIC  
amd64

When I plug-in an USB key it sees it as:

Apr 13 10:47:24 c720-r292778-amd64 kernel: ugen0.3:  at usbus0
Apr 13 10:47:24 c720-r292778-amd64 kernel: umass0:  on usbus0

Apr 13 10:47:24 c720-r292778-amd64 kernel: da0: quirks=0x2

but the command

# usbconfig -d ugen0.3 dump_info

just hangs forever. What do I wrong?
