Comment 10 for bug 350904

I have the same problem. I need usbserial as module because I use usbserial for:

1.- Develop applications that use the serial port, in my laptop I use a Serial to USB converter and require usbserial.
2.- I have a Franklin CDU-680 EVDO modem and need it.

As you can see, passing the vendor in the grub is not an option for me.

My workarround. If you upgrade (as I did), boot with your old kernel.
