[Thinkfinger-devel] Doesn't work with libusb-win32

[Thomas Harning Jr.]

I'm trying to get this to work w/ libusb-win32 so that I can have a
lightweight open-source driver for the KByte UPEK fingerprint reader
that works on all platforms.

I tested this fingerprint reader w/ thinkfinger on Linux and it worked
w/ flying colors. However... When I try to get this to work on
windows via libusb-win32... it just keeps sending out data in an
ask-scanner raw loop in init. I used a USB sniffer and found that the
device responded in the beginning of the device setup, then it hit the
look and no device data sent back (so it appeared).

Any ideas?

Hi Thomas,

Sorry for the lag.

Hey, nice idea. I haven't thought about that yet.

Hm, I'd really have to look into this on a Windows box...

Great, can you please compare the traffic when using the binary driver
with the one caused by libthinkfinger? If you could provide logs of the
sniffing session please pass them to me (off-list, as I don't want to
spew the list with large attachments).

Thanks,

Timo
