How do I specify a usb device driver

Asked by tomdean

I have an usb SDR-IQ from rfspace. I also have usb<->serial devices.

I want the ftdi-sio driver to connect with the serial devices.

I want the ft245 driver to connect to the SDR-IQ, ID:0403:6001

I created /etc/modprobe.d/sdriq.conf containing
alias usb:v0403p6001d*dc*dsc*dp*ic*isc*ip* ft245
alias usb:v0403pF728d*dc*dsc*dp*ic*isc*ip* ft245

But, looking at /var/log/messages, ftdi-sio is still connected to the SDR-IQ

I rebooted a 2nd time. Now, the ft245 driver is connected to the SDR-IQ
as /dev/ft2450.
