[sane-devel] Canon 4200F USB chip location

[LUH LAH]

Hello there!

I recently acquired a Canon 4200F scanner and realized after extensive
research that the USB chip couldn't be found. So, I opened up and
de-soldered the mainboard RF shield/Heat Sink to find a bunch of
chips.

I've attached said images to this message.

My question is, what chip is exactly for the USB port?

Thank you very much!
