USB open error [errno 2]
Hello, I am using mppsolar with Easun SV4 connected with USB cable to Raspberry 3B+. Protocol P17 and P18. I send data to nodered with json_mqtt output. After some working time (random time) connection with mppsolar stop working. If i unplug /plug usb cable connection is good again.
I use config file [GSdata] protocol=PI17 port=/dev/hidraw0 baud=2400 command=GS outputs=json_mqtt
[workmode] protocol=PI18 port=/dev/hidraw0 baund=2400 command=MOD outputs=json_mqtt
my error in command line: pi@raspberrypi:~ $ sudo mpp-solar -p /dev/hidraw0 -P PI17 -c GS -I 2022-07-12 19:51:18,502:INFO:init:main@223: Solar Device Command Utility, version: 0.13.0, add postgres support from skoky 2022-07-12 19:51:18,503:INFO:init:main@347: Creating device "unnamed" (type: "mppsolar") on port "/dev/hidraw0 (porttype=None)" using protocol "PI17" 2022-07-12 19:51:18,514:INFO:init:get_port@89: Using hidrawio for communications 2022-07-12 19:51:18,529:INFO:init:main@404: Looping 1 commands 2022-07-12 19:51:18,529:INFO:init:main@415: Getting results from device: mppsolar device - name: unnamed, port: <mppsolar.inout.hidrawio.HIDRawIO object at 0x75e44eb0>, protocol: <mppsolar.protocols.pi17.pi17 object at 0x75e5d8f0> for command: GS, tag: GS, outputs: screen 2022-07-12 19:51:18,530:INFO:device:run_command@274: Running command GS 2022-07-12 19:51:18,531:INFO:pi17:get_full_command@914: Using protocol b'PI17' with 47 commands 2022-07-12 19:51:18,531:INFO:device:run_command@303: full command b'^P003GS\r' for command GS 2022-07-12 19:51:18,532:INFO:init:get_output@35: attempting to create output processor: screen 2022-07-12 19:51:18,536:INFO:screen:output@19: Using output processor: screen Parameter Value Unit error USB open error: [Errno 2] No such file or directory: '/dev/hidraw0'
it looks like the usb device is 'disappearing' are there any system messages at the time (dmesg or /var/log/messages)

this is a part of what is listed after enter dmesg in command line. but mppsolar is working at this time
see if you can get a dmesg the next time it fails

this time connection fails and then start again after few minutes
easun and 2 pzem AC meter are connected to a HUB. Then HUB connected to raspberry. From the error message i think the HUB is disconnected from system (ttyUSB0, USB1 - PZEM RS485 connections)
I use this with node red. So, I made a function if nothing is received from inverter or an error is received, after 30 sec. will send a usb reset request for /dev/hidraw0 raspberry port. I made a counter to see how many times is reseting (7-8 times per day).
So, I believe the case is closed.
