I'm on a Redhat 7.2 system and I have a USB modem type device the is not matched up with any driver by the system. Is there a way to "bind" it to the ACM module?

In general, how do devices and drivers get matched up?

My understanding of the way USB works leads me to believe that there is no user control of what driver is attached to a device. If Linux, while enumerating the USB devices, detects that your modem conforms to the Universal Serial Bus Communication Device Class Abstract Control Model (USB CDC ACM) specification, then it'll load the ACM driver for the device. Unfortunately there are a number of modems that use proprietary interfaces and thus won't work with the ACM driver (if even if you could force the driver assignment).

I have had partial success!

> insmod usbserial vendor=0x???? product=0x????

This got my device matched up with the usbserial module and I can send AT commands to the device's data port. Still experimenting to see if I can get more functionality from the device.

Didn't realize I had this one hanging around. Sorry for the wait.

This question has become moot but I'll give the points to jlevie
