I recently got a permanent Internet connection at home thanks to Vodacom's HSDPA connectivity solution and my brand spanking new Huawei E272 modem. So now I sit here, happily surfing at around 1.5Mbps.
After a lot of Googling and things, I started to wonder if I'd ever get my modem to work under Linux. There were posts about the E220 and the E620, but I had almost nothing come up on the E272. However, the standard Linux Device Rule came to my aid: When in doubt, just plug it in and see what happens.
