ICC not activated

  apdu, c++, smartcard

I am currently trying to hack my way into Smart Cards but I am now stuck at reading anything useful from the Card. I am trying to send a SELECT FILE Command (0x6F, 0xB, 0x00, 0x00, 0x00, 0x00, 0x01, 0x01, 0x00, 0x00, 0x00, 0xa4, 0x04, 0x0c, 0x06, 0xd2, 0x76, 0x00, 0x00, 0x01, 0x02) to my Card (after PC_to_RDR_IccPowerOn, which returns the correct ATR) with the PC_to_RDR_XfrBlock Command.

But my response has the bmICCStatus Flag set to 0x40 which indicates the "ICC is present and inactive (not activated or shut down by hardware error)" but I am not quite sure what to do with that information. How am I supposed to activate the Card? I thought powering it was all there was to it.

It is very much possible that I am just blind and it is written in the Specification but I was not able to find it and my Google Searches lead me to exactly 1 SO Question, which didn’t really corrolate with my problem.

I am using libusb 1.0 and C, but I don’t think that this is relevant to the question, as
is a "reproducable code example" as my question is based on a Specification and not a bug.

Thanks in advance
