Re: Device not responding error when a USB mass storage device is disconnected



If that problem is reproducible, I suggest you report that using http://bugreporter.apple.com

Hello Group

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
