[Borden Rhodes]

Package: aes2501-wy
Version: 0.1-5
Severity: normal

I use a Fujitsu Stylistic 5020D tablet which, according to lsusb, uses an 
AES2501 fingerprint scanner:

... However, when I try to run aes2501, the output I get is:
argc=1 Initializing, please standby...
No device found

If something needs to be configured, then this is a bug in the documentation 
(since there isn't any).  If no configuration is needed, then this is a bug 
with the program.
