Hello, I have a device (a microscope automation controller) which has a USB port which uses a standard RS232 to USB converter, by Cypress. They just changed their vendor id and product id from the standard cypress ID. I added their IDs to the cypress_m8 source, compiled, and put the updated cypress_m8.ko file in /lib/modules/. When I plug the device the cypress_m8 driver isn't being used. Instead, the generic usbhid driver is used, which isn't what I wanted. If I run: modprobe -r usbhid cypress_m8 modprobe cypress_m8 modprobe usbhid then when I plug the device, the cypress_m8 driver is being used, and I can use /dev/ttyUSB0, just as I wanted. It seems that the order in which drivers are loaded affects the priority: the driver which was loaded first gets to catch the device. So my question is, is there a way to permanently change the driver priority, so that the right driver will be loaded by default?
