-/* Driver for USB SCSI - include file
- *
- * (C) Michael Gee (michael@linuxspecific.com) 1999
- *
- * This driver is schizoid  - it makes a USB scanner appear as both a SCSI device
- * and a character device. The latter is only available if the device has an
- * interrupt endpoint, and is used specifically to receive interrupt events.
- *
- * In order to support various 'strange' scanners, this module supports plug-in
- * device-specific filter modules, which can do their own thing when required.
