Confirmed
Bug description:
Binary package hint: network-manager
Running my Huawei USB modem (Bus 002 Device 007: ID 12d1:1001 Huawei
Technologies Co., Ltd. E620 USB Modem) in Lucid Beta 2 amd64 (uname -a
= Linux laptop-hostname 2.6.32-19-generic #28-Ubuntu SMP Thu Apr 1
10:39:41 UTC 2010 x86_64 GNU/Linux) and, after the same
usb_modeswitch used in Intrepid, connection is fine.
If signal is lost causing modem hangup, reconnection is not possible
without unplugging modem, replugging, usb_modeswitch and then
reconnect.
