is AX1500i supported?

[tchwpkgorg]

I'm trying to use cpsumoncli with Corsair AX1500i - however, /dev/ttyUSB0 is not even created when I connect the PSU. lsusb shows the power supply.

lsusb -v:

you need to bind the driver:

lsusb -t

you'll see output similar to this:

root@RIG1:~/cpsumon# lsusb -t /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 10000M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/10p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M | Port 6: Dev 2, If 0, Class=Vendor Specific Class, Driver=rt2800usb, 480M | Port 11: Dev 3, If 0, Class=Vendor Specific Class, Driver=cp210x, 12M

only your Driver=cp210x will probably just say Driver=, 12M

you need to bind /dev/ttyUSB0 with the driver using the following command:

echo -n "1-11:1.0" > /sys/bus/usb/drivers/cp210x/bind

1-11:1.0 was my case because the device is on bus 1 port 11, substitute your bus / port number in place of my "1-11"

i also had to do echo -n "1-11:1.0" > /sys/bus/usb/drivers/cp210x/unbind

then

echo -n "1-11:1.0" > /sys/bus/usb/drivers/cp210x/bind

again before the device would answer.

then

~/cpsumon# ./cpsumoncli /dev/ttyUSB0 Corsair AXi Series PSU Monitor (c) 2014 Andras Kovacs - andras@sth.sze.hu

Dongle name: USB to SMB Bridge (Firmware by Ross Fosler) Dongle version: 0.9 PSU type: AX1200i Fan mode: Auto Fan speed: 0.00 RPM Temperature: 41.25 °C Voltage: 237.00 V Current: 2.42 A Input power: 566.99 W Output power: 542.00 W Efficiency: 95.59 %

Took me a bit to find this out too!
