Using an Archos 3G modem with an Acer Iconia tab (Android Honeycomb) I've recently purchased an Acer Iconia tablet with Android 3.1. Then I adquired an Archos G9 3G USB modem, with the intention of having internet connection on my tablet when not around a wifi (90% of the time for me, sadly). I thought using it would be simple, like with a PC: insert the USB modem on the tablet, it recognises it, asks me some questions to configure it and so on. 

But no, when I insert the USB modem on my tablet it does absolutely nothing. I've searched on the net for instructions about this but haven't found any. Is this USB modem intended for using only with Archos tablets? Anyone on my situation?
It's plug-and-play on your PC because the industry has an established standard for driver infrastructure in Windows &amp; OSX. Android isn't as friendly to 3rd party drivers. There's some limited success reported with specific models of 3g dongle - you may need to switch devices. Here's a partial list from XDA:
