For some reason, although the umts device is mapped to /dev/ttyUSB0,
/dev/sda comes to be `busy'.  So, if I add in fstab another line:

/dev/sdb        /mnt/sdb 	vfat    rw,user,noauto       0       0

, I can mount the pendrive on /mnt/sdb.

It remains to understand:

1) whay is /dev/sda like `busy' although the modem is mapped to /dev/ttyUSB0?
2) how can I mount it and look inside it?
