opensc: smart card reader not found

Hello. I am running Slackware-14.2 with kernel 4.4.182. I have a smart card reader that is correctly recognized in dmesg:

Code:[ 739.052032] usb 1-1: USB disconnect, device number 2
[ 740.118186] usb 1-1: new full-speed USB device number 5 using xhci_hcd

[ 740.285266] usb 1-1: Manufacturer: Circle
[ 740.285270] usb 1-1: SerialNumber: 6F99FEE7I got the reader with its driver for Linux: comitex_ccr7115_2.0.6-1_amd64.deb, which I installed after converting it to txz by deb2tgz. lsusb -v also recognizes the smart card reader:

.....However, opensc does not recognize the smart card reader:

Code:root@sasho:/etc/rc.d# opensc-tool -l
No smart card readers found.and pcsc_scan freezes like this:

Code:root@sasho:/etc/rc.d# pcsc_scan
PC/SC device scanner

Waiting for the first reader...Any ideas will be appreciated.
