fingerprint-gui "Could not open fingerprint device"

Hi,

I'm getting the below error from fingerprint-gui

Code:

 "Could not open fingerprint device"

I have a TCS1C EIM/STM32 Fingerprint sensor (Upek).

lsusb shows

Code:

Bus 002 Device 007: ID 147e:3001 Upek TCS1C EIM/STM32 Fingerprint sensor

Anyone else have issues with this device? I've tried root account in case it was a genuine permission config issue - no difference.

I'm running Mint 17.1 (Ubuntu 14.04)

Dumb question, did you try using sudo when starting up the software you are using?

So I found this article https://launchpad.net/~fingerprint/+...ingerprint-gui and it appears that your fingerprint scanner is supported. In the instructions, did you log out/in after the installation?

Hi,

Yes, I've run the software as root. No change.

After log-out / log-in didn't work, I rebooted... No change.

Noticed this in kern.log

Code:

Will do some more digging...

Looks like it might be an xHCI issue with my kernel.... 3.13.0-24-generic
