Hi all, I am connecting a usb-serial dongle to a RPI3b+ with NetBSD-10.0, actually i tried with 3 dongles and the result is similar: When i connect the device i see this in dmesg: ---- this is a USB -- RS-485 adaptor --- [ 794.003535] uftdi0 at uhub1 port 4 configuration 1 interface 0 [ 794.003535] uftdi0: FTDI (0x0403) FT232R USB UART (0x6001), rev 2.00/6.00, addr 4 [ 794.013536] ucom0 at uftdi0 portno 0 ---- Now i would expect to see a /dev/ucomX appearing, but i don't see it. Unplug the device, try with another ---- this is a usb-serial ----- [ 982.132525] uslsa0 at uhub1 port 4 configuration 1 interface 0 [ 982.142526] uslsa0: Silicon Labs (0x10c4) CP2102N USB to UART Bridge Controller (0xea60), rev 2.00/1.00, addr 4 [ 982.152528] ucom0 at uslsa0: Silicon Labs CP210x ------------------------------- Still, i don't see /dev/ucomX in /dev Probably i am missing something, any advice ? bye Nicola
