Oops - the first pattern matches everything so the rest will have no effect:-)
The man page says:
filter -- List of patterns to apply to devices found by a scan.
Patterns are regular expressions delimited by any character and
preceded by a (for accept) or r (for reject). The list is tra-
versed in order, and the first regex that matches determines if
the device will be accepted or rejected (ignored). Devices that
don't match any patterns are accepted. If you want to reject
patterns that don't match, end the list with "r/.*/". If there
are several names for the same device (e.g. symbolic links in
/dev), if any name matches any a pattern, the device is
accepted; otherwise if any name matches any r pattern it is
rejected; otherwise it is accepted. As an example, to ignore
/dev/cdrom you could use: devices { filter=["r|cdrom|"] }
