Hello
I've a problem with a PN532 not being recognized by raspberry, probably becauseit is not being recognized.
In the /dev/ folder the ttyUSB file is missing

Code:

root@raspberrypi:/dev# ls | grep USB
Also, the lsusb command seems to not retrieve something useful

Code:

root@raspberrypi:~# lsusbBus 001 Device 005: ID 0424:7800 Microchip Technology, Inc. (formerly SMSC)Bus 001 Device 003: ID 0424:2514 Microchip Technology, Inc.
