Hello, I try to download your Serial USB Terminal app and connect my Wavecom Fastrack (MULTIBAND 900E 1800). It runs well most of the day until today, when i tried to dial USSD with command AT+CUSD, it always show connection lost, but after i reconnect the device, it shows the USSD reply. Why is this happening? And how can i fix this? It also happen in my code which use your library, it shows this error "USB get_status request failed". So i tried to debug it with you apps, and the apps show a similar error of disconnecting when i dial USSD.

Thank you in advance IMG_20231106_172416

maybe power supply from your Android device is too weak

is there any ways / configuration that i can make to give more power? But i also try connecting the device to my Mac and also got disconnected.

You should try with external power supply
