ReHi,

Thank you for your input!

'mount' tells me, there are no unintentional mounts. There is no
/dev/sr* special file available after connecting the modem (see below).

alpine:~$ sudo modprobe usbserial vendor=0x12d1 product=0x1505
alpine:~$ ls -l /dev/ttyUSB*
ls: /dev/ttyUSB*: No such file or directory

alpine:~$ ls -l /dev/sr*

The strange thing is, neither the ttyUSB*, nor the sr0 special files are
created, while sdb can be mounted without a hitch, after inserting a
FLASH card in the device's internal drive.

None of these problems occurred on Alpine 2.5.

Regards, Tiger
