We are developing a KEXT for a USB device. The driver continuously
reads the data from the device using bulk in pipe and then writes
the data to the bulk out pipe.
But if I have a USB mass storage device connected to my Mac and if
I plug-out the mass storage device without un-mounting the volume,
then I get device not responding (0xe00002ed) error while
attempting read/write from our device. We have handled this error
condition, by clearing the pipe stall and then re submitting the
request again.
But I am not sure if it is normal to get this error? Or do I need
to check some other part of my driver code?
Thanks in advance for your help & suggestions.
Regards
Adarsh
