[4.10-RC] usb problem

[Cyril Guibourg]

Hello,

With first 4.10-RC I was able to use a 128M PQI memory stick at least after
the very first attach following a reboot. After that, upon new attach the
kernel would not register the device and a detach made my box to reboot
(EPIA-M9000).

I just cvsup'ed today a had another try with, now it no longer registers
the device.

If I can help in doing so more tests feel free to tell me, my kernel is
compiled with USB & CAM debug.


*** A few seconds after attach:

blackbox# camcontrol devlist -v
scbus0 on umass-sim0 bus 0:
<  >                               at scbus0 target 0 lun 0 (probe0)
<  >                               at scbus0 target -1 lun -1 ()
scbus-1 on xpt0 bus 0:
<  >                               at scbus-1 target -1 lun -1 (xpt0)

blackbox# camcontrol rescan 0


^C^C^C^C^C^C^C^C^C^C^C^C^C

*** After a very looooong rescan:

blackbox# camcontrol devlist -v
scbus0 on umass-sim0 bus 0:
scbus-1 on xpt0 bus 0:
<  >                               at scbus-1 target -1 lun -1 (xpt0)
