USB scanner redirection with Dell Wyse 3020

Hi, I've several Dell Wyse 3020 ThinClient where I need to attach a USB Scanner (Canon Lide 220) and redirect it to Windows 2012 R2 RDS services

I've read some post here I see it must be added on the wnos.ini 

Device=vusb ForceRedirect=....

When I connect the scanner on the Wyse I see the added device

USB: Found a new 480Mbps device “WYSE VUSB” on port 1
VUSB: found device (Vid_0x04a9, Pid_0x1905)

But I don't find the line like

vusb: local device (0x0424, 0x2517, 0x03, 0x00, 0x01)

to insert the proper string

I've tried some combination like

Device=vusb ForceRedirect=(0x4a9, 0x1905, 0x03, 0x00, 0x01)

Device=vusb ForceRedirect=(0x4a9, 0x1905, 0x09, 0x00, 0x02)

But I can't see the scanner on the Windows 2012 R2 RDS session

Do you know if I can't see the 

vusb: local device (0x0424, 0x2517, 0x03, 0x00, 0x01)

it means that the device is not properly recognize?
