E173s does not work, although E173 is listed as supported, e173s is a new revision with different driver and it doesn't work with iconia.
I also have this stick and I lost couple if days trying to make it work, finally I bought E1552 for 10$ and it works flawlessly.
Error when searching for networks, and it is impossible to save APN. Absolutely no difference with or without the USB Stick.
I saw some people saying that after several procedures it works. Some kernel modules may be, or probably I need drivers for E173s-2.
