apparently /lib/udev/usb_modeswitch doesn't get run at all.
Renaming the rules file as 99-usb_modeswitch.rules helped a bit (don't
know why it makes a difference): now /lib/udev/usb_modeswitch is
executed, but the switch still doesn't happen. I managed to collect
strace output (attached). The interesting part appears to be:
599 open("/tmp/tcl.tmp.mDGyFD", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 EROFS
