[Linux-parport] HELP

[Ajay Kumar]

Hi,

I have a query ... Please find time to guide me out...

I was working around with usb-parallel converter, wrote a small driver for the same. LINUX 2.4.20-8



I am referring to the parport driver i.e. "uss720.c".

````````````````````````````````````````````````````````````````````````````````````````

In probe function i makea call to 



parport_register_port

and later make a call to 

parport_proc_register(pp);

parport_announce_port(pp);

and in Disconnect

parport_proc_unregister(pp);

parport_unregister_port(pp); 

i am facing the below mentioned problem :

First time I insmod the driver and plug in the device, the parallel port on the board is recognised as

/dev/lp1 and i am able to print on to this port...

functionality wise as of now i dont have any problem...

BUT, when i unplug and then plug it again, the parallel port is recognised as /dev/lp2 and this goes on 

as and when i plug and unplug... I want it to be recognised as /dev/lp1 how many ever times i plug and unplug...

Even after i rmmod the driver, the same problem persists...

as of now i am rebooting the system to reset it to work again with /dev/lp1

PLEASE SUGGEST ME ON THIS...

Thanks,

Ajay
