If anyone has any objections, please let me know. ------------------ From: Jérémy Carrat commit d84e27d87738634b92001500435ae4dadba10a13 upstream. The Corsair AX1500i power supply exposes its Corsair Link monitoring interface on a mini-USB port through an on-board CP2103, using a Corsair-specific product ID. Without the ID in the table no driver binds and no tty is created. Tested by forcing the driver association with echo 1b1c 1c02 > /sys/bus/usb-serial/drivers/cp210x/new_id and then setting the serial port to 115200 8N1. Adding the ID is sufficient to talk to the device: the tty reaches a USB-to-SMBus bridge sitting behind the UART, which identifies itself as "USB to SMB Bridge (Firmware by Ross Fosler)" version 0.9 and relays PMBus reads to the power supply controller. Input voltage and current, input and output power, internal temperature and fan speed were all read back on an AX1500i.
