regarding usb reset of an interface while probe is happening

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi ,

If an USB interface is currently being probed ( usb driver probe
routine is executing  ),
and another driver or userspace program triggers a usb reset on the
device containing this interface ,
during this time :

1) how a usb interface driver can handle such  usb reset requests
while currently being probed  ?

2)  will linux usb subsystem execute probe routine completely first
and then then do usb reset the device ?

3) if a usb interface is already claimed , why is  usb reset of this
interface  allowed by another driver  or userspace program .



Kindly find time to clarify my doubts .

Regards
Amit Nagal
