Some information about the scanner:

T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS=64 #Cfgs=  1
P:  Vendor=04a9 ProdID=220c Rev= 2.00
S:  Manufacturer=Canon
S:  Product=CanoScan
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 10mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E:  Ad=81(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=83(I) Atr=03(Int.) MxPS=   1 Ivl=8ms

I think the scanner uses a SQ Scan09 ASIC 
and a Philips ISP1581 USB 2.0 Controller

The CCD sensor is a NEC µPD 8872.
