Public bug reported: My 3G USB dongle (Huawei E1552/E1800) doesn't modeswitch automatically.
I can get it to work using following magic in /etc/usb_modeswitch.conf DefaultVendor= 0x12d1 DefaultProduct=0x1446 TargetVendor= 0x12d1 TargetProductList="1001,1406,140b,140c,141b,14ac" CheckSuccess=20 MessageContent="55534243123456780000000000000011060000000000000000000000000000" and then forcing it using: sudo usb_modeswitch -c /etc/usb_modeswitch.conf == Details == Output from lsusb: Bus 002 Device 009: ID 12d1:1446 Huawei Technologies Co., Ltd.
