Let me do a newbie question, please sorry if it's a too dumb question.

Would it be possible to change the firmware ( or something else ) of the 2Pac GekkoScience to mine with a different algorithm? Like Scrypt?

For firmware, not likely, the 2pac is an ASIC. Meaning its designed specifically for a single algorithm and this is hard coded into the hardware during manufacturing. They could release another version of the 2pac with different a algorithm but the one you already have will remain as is.

No. That is not how firmware works and there is nothing else you can change on the 2PAC to change its algorithm.

Yes and yes. These Bitcoin ASICs are application specific to Bitcoins.

Long answer:

Logically bitcoin hashing involves a double SHA256: SHA(SHA(x)).

Dear All,
i have got some odd issue with gekko Science U10 SHA256,
i have got three of these are connected on USB power HUH. but Cgminer is only detecting on USB miner
can anyone please help on it
thanks
bye

But most application specific one does a: SHA(m [+ s] + MODIFIEDSHA(w + n)) and checks for leading zero then returns n.
m=pool created midstate,
s=driver created partial sha (chip specific),
w=driver created leaftover from x,
n=chip created nonce

Which results in logically a SHA(SHA(x)) at the pool.

Short answer:

They are hard wired and not programmable in any way.
