 I don't do much with the smartcard software anymore (or netbsd for that mat=
 ter). I did attempt to set up a 5.1 testbed to see if I could replicate the=
  original problem, but the smartcard software has moved on,and now uses lib=
 usb on netbsd which does not seem to tickle this. (The pre-libusb code seem=
 s to not work right anymore).=0A=

 I attempted to write a simple test program (open /dev/ugen0.00 and poll it)=
 , but it doesn't crash on 5.1. It looks like some refactoring in ugen.c 1.8=
 4 masked the issue (->edesc is not dereferenced if ->pipeh is null).=0A=
