[Risolto] Ubuntu 18.04 mate non vede smartwatch T8 via USB

[Sargonsei]

Ho da poco acquistato uno Smartwatch T8 tipo questo
http://www.sureshop.it/telefonia-tablet ... sport.html
L'ho dotato di una microSD da 32 GB, e l'ho caricato connettendolo con l'apposito cavetto alla porta USB del PC con Ubuntu 18.04 mate.
Durante la carica, sul display dello Smartwatch era visibile il simbolo della batteria che si ricarica, null'altro.
Anche dopo che sul display dello smartwatch è comparsa la scritta che comunicava il completamento della carica, Ubuntu Mate 18.04 si ostinava a non vedere alcuna periferica USB

Qualcuno è in grado di indicarmi come leggere il contenuto della memoria dello smartwatch via USB?

[magozurlinux]

Ciao.

C'è la possibilità di metterlo in modalità multimediale?

[Sargonsei]

Se esiste la possibilità di metterlo in modalità multimediale, io non so come si possa fare.
Ho notato che, se uso un cavetto USB diverso da quello fornito con lo smartwatch, Ubuntu Mate lo vede; infatti

Vai in fondo a questo link, che hai postato nella prima discussione:

http://www.sureshop.it/telefonia-tablet ... sport.html

Contenuto del pacco
- 1 x Smart Watch T8
- 1 x Manuale Utente (In Inglese)
- 1 x Cavo di Ricarica

Il cavetto usb fornito con lo Smart Watch T8 serve solo per ricaricare la batteria, cavo usb tipo per powerbank.

Per vedere il contenuto della schedina SD dello smartwatch devi usare un cavo usb dati come quelli forniti per gli smartphones.

Ciao

[Sargonsei]

Usando un cavetto USB diverso, riesco a fare in modo che il terminale individui la periferica,

ma non riesco nè ad accedervi col file-manager, nè a montarla in lettura
qui
https://domandesunix.com/questions/3662 ... e-non-rico
si espone una soluzione; mi pare di capire che il file da modificare sia
/lib/udev/rules.d/40-usb_modeswitch.rules
ma proprio non capisco cosa devo farci...

$ cat  40-usb_modeswitch.rules | egrep -a1 0e8d

Ciao.

Quello è relativo al modem dello smartphone per farlo funzionare come chiavetta Internet.

Hai provato tramite la procedura MTP?

[Sargonsei]

Ho provato a connettere lo smartwatch T8 al computer con Ubuntu mate 16.04 usando il bluetoot, ma nessuno dei due dispositivi trova l'altro.
Ho provato a connettere lo smartwatch T8 al computer con Ubuntu mate 16.04 usando un cavetto USB in grado di fare il trasferimento dati (il cavetto USB venduto assieme allo smartwatch consente unicamente di caricarne la batteria); lo smartwatch T8 segnala che lo smartwatch è in carica, e da riga di comando, l'output di lsusb mi mostra che c'è una nuova periferica connessa alla porta USB.

Non ho idea di come avviare né la procedura MTP, nè qualsiasi altra procedura.

Risolto commentando la riga

ATTR{idVendor}=="0e8d", ATTR{idProduct}=="0002", RUN+="usb_modeswitch '/%k'"

del file

Codice: Seleziona tutto

/lib/udev/rules.d/40-usb_modeswitch.rules

Adesso il mio output è

e riesco ad accedere alla memoria flash dello SmartWatch T8 connesso alla porta USB

Preciso che, col metodo qui descritto, la memoria flash dello SmartWatch T8 connesso alla porta USB è accessibile solo se lo SmartWatch T8 è SPENTO

[magozurlinux]

Perfetto!

Commentando la riga che la fa switchare a modem del file /lib/udev/rules.d/40-usb_modeswitch.rules, il dispositivo viene rilevato come dispositivo di massa. facendo vedere il contenuto della schedina SD.



Ciao

[Sargonsei]

A questo punto, esprimo il mio parere sullo smartwatch T8.
Come orologio, funziona bene, e dà all'utente la possibilità di scelta fra 3 diversi quadranti digitali simil-analogici;
La fotocamera è scomoda da usare, e permette l'utilizzo di risoluzioni bassissime (min. 160x120, max 320x240 pixels)
La porta micro-USB funziona bene unicamente come connettore per caricare la batteria.
Il metodo da me qui descritto per accedere alla memoria flash micro-SD, funziona "a singhiozzo"
Il collegamento via bluetoot non viene rilevato da Ubuntu
A conti fatti, ne sconsiglio l'acquisto.
