Comment 55 for bug 105545

Adding info about abother model.

I have access to an E620 which suffers from the same behaviour: when plugged, both the storage and modem devices are recognized, storage is mounted ro, but ttyUSB devices are not created. Removing the usb-storage module makes the ttyUSB devices to be auto-detected after about 30s.

It has the same characteristics as described above for the E220, except it has product id 1001, instead of 1003. I'll attach commented logs from messages, syslog and lsusb -v.
