Getting a Huawei EC159 USB Modem working on Ubuntu 11.04

The EC159 just like any USB modem gets detected as a USB mass storage or virtual CD-ROM when connected to Linux boxes. Yes, usb-modeswitch should take care of this and make it available as a GSM Modem. Unfortunately, the usb-modeswitch configuration skips this particular device, and that’s what I felt.

I decided to run usb-modeswitch to manually configure the modem by the following steps:

1. Get the latest release of usb-modeswitch

2. Build and install it.

3. Plug in the modem and run lsusb. Note down the vendor ID and Product ID.

For example:  Bus 002 Device 002: ID 8087:0020 Huawei

The vendor ID is 0x8087 and Product ID 0x0020

4. Run usb_modeswitch -H -v <vendor ID> -p <product ID>

5. Now modeprobe using the same vendor and product ID

sudo modprobe usbserial vendor=<your’s here> product=<your’s here>

6. Your device will start working like a charm!
