Hi All,

I have some clarifications on usbserial driver are as follows 

First one is on usbserial module count usage. 

When I'm disconnecting a device and module count is not reduced, when we
remove the device, driver invokes disconnect function and unlink all URB
related transactions other than decrementing the module count. 

Please tell us how to decrement the module count after disconnecting the
device.

My Second clarification and my observation on close function
 
After connecting a USB device to the system, open Kermit application and
give check for power status and give AT+CFUN=0 command, after execution
of this command device disconnects and connects it back to the system. 

If we close Kermit application after above steps, it closes the
application and calls destroy serial function to unlink URB's. Again if
we try to open the device, it does not open, since its already closed
and unlinked URB requests, until we again disconnect and connect it back
we can not open the device. 

Please tell me the significance of calling destroy serial function in
close function and how to avoid this problem.  


Regards,
Shalini G
