udev or hotplug

udev or hotplug

[Danny Budik]

Hello all,

I would like to automate two steps in Linux when I plug in a wireless 
modem card into a PCMCIA slot.  When I plug it in, I need to run the 
following 2 commands for the card to be recognized properly before I can 
run the pppd command to connect:

#modprobe usbserial vendor=0x1199 product=0x0112
#mknod /dev/ttyUSB2 c 188 0

Is there a way to automate this by writing a udev rule so that whenever 
the computer sees the device, it loads the usbserial driver and maps it 
to /dev/ttyuUSB2? I seem to be getting the feeling that udev is the "new 
hotness" and hotplug is "old'n'busted" and is being phased out.

This looks like an evdo card setup. In the usb/serial directory, you
will see a file called airprime.c. You can put your setup there as a
USB device in there, possibly...

Though, is it this one? off of line 19:

{ USB_DEVICE(0xf3d, 0x0112) }, /* AirPrime CDMA Wireless PC Card */

If so, you may just need to 'modprobe airprime'
