How PCAN-USB FD works ?

[hmluqman]

Hi
I am basic learner. I am wondering how PCAN-USB FD works. Does it work like Virtual COM Port where a driver emulates a USB port as COM port ?
Is USB to CAN hardware assigned a address or does enumeration happens ?
What PCAN USB FD functions perform on electrical level, how protocol conversion happens from CAN to USB ?
What driver plays role in PCAN-USB FD case ?

Hi,

all our PCAN-USB interfaces use an own device driver called "pcan_usb.sys" and no virtual COM port. What do you mean with "Is USB to CAN hardware assigned a address or does enumeration happens ?"?

best regards
