[fprint] 1307:1171 Transcend Fingerprint Reader

[Benjamin Lim]

Hi,

I have captured the packets on Wireshark on Linux while running Windows 
XP in virtualbox.It appears to break down the prints into pairs of 
packets around packet no.1266. I have no idea how to interpret the 
capture data. Would appreciate some assistance.

The insertion capture is here:

Reading capture is here: http://www.comp.nus.edu.sg/~benjamin/fp/reading

Thanks.
