I want to write a udev rule to load a driver for a hardware speech synthesizer. Many synths have both USB and serial connectors. The linux screen reader always uses the serial port. But I thought I could write a udev rule to detect when the synth is plugged into the USB port and then load the driver for the serial port. So a blind person would have to plug the synth into both the serial and the USB ports but I don't figure that is a problem. It is way easier than trying to log in without speech and then try to type in the modprobe command. I am hoping to write a whole series of these rules and then make them available for download.<br>
<br>
I got a rule to work but it seems to try to load the driver several times. Is anybody experienced enough with udev rules to tell me if this is a problem and if so, how it can be fixed? Here is my rule:<br>
<br>
ACTION=="add", SYSFS{idVendor}=="0dd0", SYSFS{idProduct}=="1002", RUN="/sbin/modprobe speakup_ltlk"<span class="HOEnZb"><font color="#888888"><br>
