I(Igorli) extracted firmware for Acorp DS120 from DVBUSBS2102.sys file. It lays: offset 0x47C0, length 8192(0x2000). Script to extract it:

#!/usr/bin/perl

use File::Temp qw/ tempdir /;
use IO::Handle; 

    extract("DVBUSBS2102.sys", 0x47c0, 8192, "dvb-usb-dw2102.fw");

According to Usbsnoop.log, firmware loads in receiver by 64 bytes length chunks. It seems through endpoint 0.
