USB network adaptor, a replacement for Sony network adaptor, it should be OK for SMB
Someone used the USB network adaptor (non sony network adaptor) for online game on 2002 already, by then sony still not yet released the network adaptor. So, it can be a replacement for sony network adaptor and run the SMB network games through Openusbld0.6. Is it possilble ? Furthermore, there is a cheap version with the same function ! It costs about US$3-4 here.
