mount /dev/sr0 should mount it.
If not, looks more like a kernel/modules problem.

lsmod please ?

Could not tell more, except that something similar did happen when I was
trying gsm or cdma modem 1 yrs back, but now is ok.

dmesg shows sr0 and modem.
so try again:

$ sudo rmmod usbserial
$ lsmod # if you still see usbserial, you need to figure out how to rmmod it
$ eject /dev/sr0 # do it anyways
$ sudo modprobe usbserial vendor=0x12d1 product=0x1505
$ dmesg | tail -n 24

you said you did 'sudo apk -U upgrade' , does this still happen with fresh rc2
.iso install ? if yes, more likely a kernel/module issue.
