found USB scanner (vendor=0x04a9 [Canon], product=0x2212 [CanoScan]) at
libusb:001:004
###############
so I opened the device and made some photos.
There is a "very big" chip with lots of pins on all four edges, which is
labled with:
Mercury 03
A234-0604
FFHWA-2
There is also a chip with pins on two edges, which is nearer to the
usb-port and labled with:
tm (superscript) TE (subscript) C (obviously some
company name)
7S
0212
T431616A EP0539X
I will also attach a photo of this.
