VFS300 [138a:0008]

[Hieu D. Bui]

Hello,

I have a VFS300 fingerprint sensor in my Dell 3400 Laptop. I've try
your program (both the perl script and protocol test in git repository)
but it doesn't work at all.

I found out from UsbSnoop log that with VFS300, the sequence number is
mixed up (an example is attached in this email), and the current code
will not work with VFS300.
I hope you can change the code to adapt to this situation.

I'm trying to understand the message from UsbSnoop log and find out
the protocol but I have little knowledge about USB. Would you like to
give me some links or documents so that I can get started to analyze
the log file.

P/s: I can provide the logs for you to do the analysis.
