This is from Uniscan D50 windows INF files:
; UMAX Astra 4800/4850 for Windows 98
; Writing by Vikas on 16th May 2003.
; Copyright by UMAX Data Sys. Inc.
%Leopard.DeviceDesc24% = Leopard.Scanner,  USB\VID_1606&PID_0170

This is from UMAX Astra 4800:
; UMAX Astra 4800 for Windows XP
; Writing by Wen-Yung Huang on 24th Dec 2002.
; Copyright by UMAX Data Sys. Inc.
%Leopard.DeviceDesc% = Leopard.Scanner,  USB\VID_1606&PID_0350

So Uniscan D50 seems to be very close to UMAX Astra 4800/4850, if not the same 
with only ID changed.
