Hello I suffered the same problem. My Huawei E353 Mobile Broadband dongle on Ubuntu 16.04.6 LTS stopped working after the following updates:-

N.B. The dongle still works, however, on Ubuntu 14.04.5 LTS.

It seems to be a problem related to 'usb_modeswitch'. If you do a search on the internet then this seems to be a problem that continually reappears for various ubuntu versions over the last decade. Here is a short term solution I found that worked for me:- 1). Plug your dongle into usb port and wait until it indicates a signal has been detected. 2). Do a 'Ctrl-Alt-t' to get a terminal window up. 3). In terminal window type 'lsusb' and then hit return. 4). One of the entries in the output should read something like:- 'Bus 001 Device 004: ID 12d1:1446 Huawei Technologies Co., Ltd. Broadband stick (modem on)' 5). Make a note of the two hexidecimal numbers after the 'ID' i.e. in this example '12d1' and '1446'. 6). In the terminal window type:- 'sudo usb_modeswitch -v 12d1 -p 1446 -J' replacing the numbers after the '-v' and '-p' with the numbers you made a note of in step 5). above and hit return. 7). The output looks something like:- 'Look for default devices ... product ID matched Found devices in default mode (1) Access device 004 on bus 001 Current configuration number is 1 Use interface number 0 Use endpoints 0x01 (out) and 0x81 (in) USB description data (for identification) ------------------------- Manufacturer: Huawei Technologies Product: HUAWEI Mobile Serial No.: not provided ------------------------- Using standard Huawei switching message Looking for active driver ... OK, driver detached Set up interface 0 Use endpoint 0x01 for message sending ... Trying to send message 1 to endpoint 0x01 ... OK, message successfully sent Reset response endpoint 0x81 Reset message endpoint 0x01 Device is gone, skip any further commands -> Run lsusb to note any changes. Bye!' 8). In terminal window type 'lsusb' and then hit return. 9). The entry noted in step 4). above should now read something like:- 'Bus 001 Device 005: ID 12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard' 10). The dongle interface should now appear in 'Network Tools' and you should be able to connect as usual. 11). You need to go through this everytime you reboot until an update fixes the bug. Not ideal but a life saver if you can only connect to the network using this device ! regards, Kevin Morgan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817410 Title: After last software update Huawei 3372H-153 modem is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1817410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
