I am connecting a USB-A cable to my Digi ConnectCore 6UL running Yocto into the top stacked USB port. The cable is connected to a serial converter which is connected to UART on another device (which is working properly as tested with other linux devices). When I plug the cable into the ConnectCore, I see some serial activity indicated by flashing LED on the serial converter.
Issuing the “usb-devices” command I see the serial converter listed:
T: Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 6 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0403 ProdID=6001 Rev=06.00
S: Product=FT232R USB UART
C: #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=90mA
I: If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
However, there doesn’t appear to be a serial device (i.e. /dev/ttyUSB0 or similar) associated with my connected device. I do see /dev/ttymxc0 - /dev/ttymxc3, but those are there regardless of what is plugged in and none of them are mapped to my USB device.
So, is there something I am missing here, perhaps configuration step that will get my serial USB device mapped to /dev/tty device? Thanks, Craig
