Dear friend I have tried everything. Thing is that the cd rom partition of my pendrive is detected as audio cd. This is not OS problem. The problem is with pendrive version. So I would like to try firmware upgradation. Please suggest me how to do this.
Mean while if somebody can provide me a sandisk U3 launchpad ( version 1.6.3.9 ), I would like to install it and try to run. I am not able to download 1.6.3.9 version of launchpad. Every time I try, the website always gives me 1.6.1.2 version.
