Summary0000656: lsusb - crashes on one of my devices
Descriptionlsusb-20130526.zip,libusb-1.0.16-rc6-20130525.zip:

When I run "lsusb" without any switch I get an overview of all attached USB devices.

However if I attach one particular device and rerun "lsusb", it always crashes with this error, it also crashes if I had the problematic device attached initially:

LIBC PANIC!!
_um_free_maybe_lock: Tried to free block twice - block=200365a0 lock=0x1
pid=0x0044 ppid=0x003d tid=0x0001 slot=0x0091 pri=0x0200 mc=0x0000 ps=0x0010
D:\OS2\APPS\LSUSB.EXE
Process dumping was disabled, use DUMPPROC / PROCDUMP to enable it.

As USB stack I have tried David's 11.13 and also my current 11.199 (11.200 in the works) but the behaviour/problem is exactly the same.



Steps To Reproduce1) plug in problematic device
2) run "lsusb"
