Well, we do not have USB host controller support for the i.MX53 yet. So
in this case you will need to first port that driver.

Alternatively, and maybe less complicated would be to connect the
Fingerprint sensor directly to a second UART of the i.MX53 QSB. AFAIK
there are two additional UARTs available via the expansion header (j13).
Of course you would need a corresponding connector[1], and propably have
to configure the IOMUX controller within our platform driver
appropriatedly to use the additional UART.

In the end you have to port the Fingerprint sensor library.

I'm not sure what you mean with "integrated". AFAIK there is no
fingerprint sensor on this board available, or is it?

[1] In the Hardware manual I've found this paragraph:
"The proper connector to mate with Expansion Port J13 is made by Samtec,
QTH‐060‐XX‐L‐D‐A, where XX determines the height of the connector."
