Hi, I'm playing with some Juniper SRX devices, which have built in usb-serial. They don't come up automatically when plugging in, however I've found I can add the Vendor/ProductID to the cp210x module and this fixes it. Something in the dmesg output suggested I emailed you to get it added to the driver. Vendor = 10c4 Product = 8470 driver = cp210x Oct 19 13:11:42 snarf kernel: [674325.109179] usb 1-1.3.4: new full-speed USB device number 32 using ehci-pci Oct 19 13:11:42 snarf kernel: [674325.213387] usb 1-1.3.4: New USB device found, idVendor=10c4, idProduct=8470 Oct 19 13:11:42 snarf kernel: [674325.213392] usb 1-1.3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Oct 19 13:11:42 snarf kernel: [674325.213395] usb 1-1.3.4: Product: Juniper Networks BX Series System Console Oct 19 13:11:42 snarf kernel: [674325.213396] usb 1-1.3.4: Manufacturer: Silicon Labs Oct 19 13:11:42 snarf kernel: [674325.213398] usb 1-1.3.4: SerialNumber: 0435005AF221 root@snarf:/sys/bus/usb-serial/drivers/cp210x# echo 10c4 8470 >> new_id Oct 19 13:13:53 snarf kernel: [674456.441668] cp210x 1-1.3.4:1.0: cp210x converter detected Oct 19 13:13:53 snarf kernel: [674456.442379] usb 1-1.3.4: cp210x converter now attached to ttyUSB0 Many thanks!
