Package: 4.9.0-3-amd64
Version: debian stretch latest kernel release
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Inserting usb wireless adapter BCM43235 into usb ports crashes kernel usb hub.
when adapter is taken out it is still listed when lsusb is executed.
reinsertion and removal several times crashes the usb hub at the kernel level
and no more usb devices work.  Have confirmed on several computers using the
same kernel (latest release in stretch 64 bit.)  Wireless adapter works on
other kernel versions.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Wireless mouse and primary usb adapter were already plugged in and working.
Other wireless cards when plugged in could not be read after hub crash.

Causes the following system errors as seen in log:
