[sane-devel] Status PrimeFilm 1800u/Microtek FilmScan35

[Matthias Prinke]

Hello,

I would like to know the status of developing a sane-backend for the 
Pacific Image Electronics "PrimeFilm 1800u".

This device (film/slide-scanner with USB interface) is apparently also 
sold as "Microtek FilmScan35", "Mediax Diascanner 1800 dpi" and 
"Reflecta i-scan 1800". (the latter two maybe only in Germany)

Has anybody already started devolopment? Did anybody get the necessary 
API-documentation from the manufacturer? What is your experience with 
technical support from PIE?

I have gathered any information I could get hold of regarding USB in 
general, the Linux USB implementation and the hardware (data sheets, 
schematics, ...). The only missing piece is the programming specification.

I already tried sniff-usb, but I got the impression that the TWAIN 
driver bypasses some parts of the Win USB stack: I got a trace of the 
enumeration process, but I didn't get anything during calibration, 
preview and scanning.

I would just like to know what has already been done before I try to 
contact Pacific Image Electronics.

Best regards,

Matthias Prinke
