Title: How to load usb module at bootup
Post by: jyoung on September 11, 2007, 04:56:14 PM

I am linux newbie.  I have a USB wireless modem( can't get DSL or Cable) and i have been able to get it to connect to the internet after much searching thru forums.  My problem is everytime I reboot, I have to redo the modprobe command for the usbmodem.  So I log into root and type :

modprobe usbserial vendor=xxxx product=xxxx

Then i can connect and go on.  My question is where and how do add this to the modprobe.conf template to work properly so I don't have to configure it each time.

I have tried each of the following with now luck

install usbserial vendor=xxxx product=xxxx
alias usbserial vendor=xxxx product=xxxx
install usbserial (/sbin/modprobe usbserial vendor=xxxx product=xxxx)


Can someone help me out with the correct line to add to the template if that is the correct place to put it?  Thanks

U might ofcourse try to set these lines at the bottom of /etc/rc.d/rc.local
AFAIK the rc.local is not affected by reboots and/or template rebuilds.

Thanks!  I can try that tonight.  Do you know if that will load before the usb ports initialize?  whenever i run the modprobe command from the root, the modem isn't recognized until i unplug and re-insert it or disable and then re-enable the usb ports.

I tried adding
/sbin/modprobe usbserial vendor=xxx product=xxxx

to the rc file like was suggeseted, but it didn't completely work.  It would load the module, but the comm drivers (ttyUSB0,1,2,3) were not available until i unplugged the modem and re-inserted it. so i then modified the rc file as this

/sbin/rmmod uhci_hcd
/sbin/modprobe usbserial vendor=xxx product=xxxx
/sbin/modprobe uhci_hcd

Now the module loads at boot, and the drivers are ready.  I can call my script to log into the network.  Now i am trying to use the ttyUSB0 as the default modem and get SME to use it instead of a serial port or isdn for default connection to the internet!

Thanks for the help, i am sure i will be back!
