Please post names of data card manufacturer,model number which work/ won't work in Linux. And also mention whether data card works out of box or requires any tweaking. This would help people who use Linux and planning to buy a data card.Manufacturer- MicromaxModel- MMX 310GCarrier- BSNL 3G.Working condition- Plug and play doesn't work in Linux. Tried in Ubuntu 10.10 and 11.10. I even tried the Linux Connectivity Suite sent by Micromax, it didn't help. The OS doesn't detect the data card at all. I was told to install USB mode_switch in Ubuntu, yet to try it.
