Is there an easy way to remove the script activation by intel to use this FSC method?

Yes, by ftp (putty,filezilla) or flash the cic

is ENET cable works on retrofitted CIC on E92?
I am trying to find USB adapter but its impossible to find Rev B1

You can also use the Utechsmart Adapter with ASIX AX88772A Chipset. It works too.

I am still struggling with connecting via usb

I picked up AX88772A chipset based usb adapter but it doesnt seems to be working.
When I plug it to globebox usb, ethernet cable shows as disconnected.
When I plug it to computer usb, etnernet cable shows as its connected.
I think adapter works but CIC does not power this usb adapter.
I tried on 2009 E90 (Factory CIC) as well but still no connection.

Any specific steps to make it work?
I thought usb2ethernet should be plug and play (at least connecting part not about ip address and communication)
