I have an official huawei e3372h-320 usb modem that i'm trying to use in "stick mode" on RPi4 (Buster). I've tried a few things already:
- booting into "recovery mode" (shorting pins with ground on plugging in) - this seems to work
- running Balong's usbdloader and flasher on RPi4, but received no output to console
- trying the same on a win10 pc, but it doesn't seem to recognize a COM port (even with drivers installed)
Any help would be appreciated.
