Yes. UMAX germany contacted me that UMAX has decided to support
the SANE development of the Astra 4500 Scanner.

I am in contact with a software manager of avison.
First information:
the scanner uses a USB scanner ASIC (type genesys logic inc GL646USB)
=> it does not use an scsi over usb protocoll and it has no firmware

I got a protocoll of this chip, a more recent version can be downloaded at:

or at

I will keep you informed about the further progress.
