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. -- Ondrej Zary
