	Hello,

	can you try to record USB activity when plugging this scanner and doing a 
preview with usbsnoop in case  we may be recognize the underlying protocol ?

	In the search engine there is the output of sane-find-scanner which quite 
old, maybe running the version from SANE 1.0.22 will bring extra data.

Regards,
	Stef
