problem with my vfs101

[rayl]

hi guys

i've grabbed the code from svn and run it on my hp laptop. i see some
differences in the protocol between my windows usb log and the output
of bin/proto.

i modified proto.c to use validity_cycle3 instead of validity_cycle4.
near the
end of the cycle, the commands are similar to my windows capture, but
the
responses are different in the two logfiles below:

- i can see that the response to the GetParam(0x11) at windows:0b9a
returns 0x08, while the
response at linux:00ae returns 0x00.

- also, the response to GetPrint(0x1388) at windows:0b9c returns 0x00,
followed by successful
polls of GetFingerState(), ultimately resulting in a fingerprint
after the poll returns 0x02.
however, the GetPrint(0x1388) at linux:00b0 returns 0x0c, followed by
an endless stream
of failed GetFingerState() calls returning 0x00.

does anyone know why this is? has anyone successfully retrieved a
fingerprint using
GetFingerState() on linux yet?

thanks
ray

here are the two logs:
