Bash Shell Read a Line Field By Field

How do I read a file field-by-field under UNIX / Linux / BSD Bash shell? My sample input data file is as follows:

device1,deviceType,major,minor,permissions
device2,deviceType,major,minor,permissions
...
....
.
deviceN,deviceTypeN,major,minor,permissions

For each line I need to construct and execute a shell command as follows:
/path/to/deviceMaker --context=$1 -m $permissions $device2 $deviceType $major $minor
