Per quanto riguarda windows, invece servono i driver.

Ok. Mmmm allora prima di dare colpe alla scheda, forse abbiamo qualche altro problema

Con cavo connesso, posta per favore output altri due comandi

1)

2)

Pare sia un prblema di regole udev.

Ti chiedo ancora due comandi

Codice: Seleziona tutto: sudo dmesg | grep -i USB

(USB minuscolo eh, non so perche tag code lo mette maiuscolo, ma ho aggiunto "-i" cosi e' case insensitive)

e, con cavo scollegato:

Codice: Seleziona tutto: lsusb

da **hyroio** » 21 mar 2020, 15:15

Prova a creare questo file

Codice: Seleziona tutto: sudo nano /etc/udev/rules.d/99-CH340-USB-Serial.rules

E metterci dentro questa riga

Codice: Seleziona tutto: SUBSYSTEM=="USB", ATTRS{idVendor}=="2357", ATTRS{idProduct}=="0109", GROUP="dialout"

Poi rivavvia udev "sudo /etc/init.d/udev restart" o il PC e reinserisci il cavo e riposta "ls -al /dev/tty*"

da **hyroio** » 21 mar 2020, 15:35

Ora ho verificato anche un'altra cosa:
Tu hai il ch340, e ci sono diverse varianti del chip, oltre che magari anche dei cloni. Il drvier Linux non prevede il tuo chip:

drivers/USB/serial/ch341.c

Codice: Seleziona tutto: 76 static const struct usb_device_id id_table[] = { 77 { USB_DEVICE(0x4348, 0x5523) }, 78 { USB_DEVICE(0x1a86, 0x7523) }, 79 { USB_DEVICE(0x1a86, 0x5523) }, 80 { }, 81 };

Il tutto si complica. Che versione di kernel hai ? Sarebbe da provare a ricompilare con

Codice: Seleziona tutto: 76 static const struct usb_device_id id_table[] = { 77 { USB_DEVICE(0x4348, 0x5523) }, 78 { USB_DEVICE(0x1a86, 0x7523) }, 79 { USB_DEVICE(0x1a86, 0x5523) }, { USB_DEVICE(0x2357, 0x0109) }, <<---- 80 { }, 81 };

Il tutto pero credo sia troppo complesso per te.

Altrimenti prova con questo driver che si trova in giro:

https://cdn.sparkfun.com/assets/learn_t ... _LINUX.ZIP

Che pero' mi pare non abbia nemmebo lui il tuo VENDOR_ID, va comunque compilato, ci vuole iun po' di pratica.
Se mi dici la versione precisa del tuo kernel, e la tua architettura, che immagino sia x86_64, posso provare a compilartelo io, poi ti passo il modulo ".ko" e lo provi a sostituire al tuo.

ora ho provato a cambiare cavo dato che non ho quello originale ma un altro che ho trovato in casa e dando il comando lsusb mi da questo:

Che versione di kernel hai.

Mi risulta che il VID:PID 2357:0109 sia un prodotto realizzato dalla TP-Link del dispositivo TL WN823N RTL8192EU quindi non identifica adattatore seriale CH340 ? Quindi indaga meglio sui collegamenti e su quali dispositivi USB hai collegato.

Edit:

Credo che sia il dispositivo USB 1a86:7523
