while it was still plugged in. The connector sheared, the board cracked, and the machine stopped seeing it entirely. The memory chip, which is the only part that matters, was untouched.

A USB stick, snapped while plugged into a laptop — the single most common way a USB stick dies, and it happens because the connector is a lever and the board behind it is not designed to be one. Somebody knocks the laptop, or closes it, or moves it with the stick still in, and the force goes straight into the solder joints.
No computer would recognise it. On it: coursework and research, with no backup and a deadline.
the board.
, breaking the power and data lines.
— and that is the whole ballgame. The connector, the controller and the board are all replaceable. The flash chip is not.
A classic USB stick has a separate controller and NAND chip on a small board. If the board breaks, we repair the board; if the board is beyond repair, we lift the NAND chip off and read it directly.
A great many modern sticks — especially small, cheap and very slim ones — are monolithic: the controller and the flash are fused into a single epoxy package with no separable chip to lift. On those, chip-off in the normal sense is not possible. Recovery means locating test points on the package itself and reading it through them, which is delicate, model-specific, and sometimes simply cannot be done.
That is why we look at the stick before quoting, and why anyone quoting a flash recovery over the phone is guessing.
The NAND was read, the translation layer rebuilt, and the coursework came back.
A snapped connector with an intact chip is one of the more recoverable failures we see. What is not recoverable is a stick that has snapped through the chip, or been through a washing machine and then plugged in to see if it still worked. The chip is the thing. Protect the chip.
Do not carry a laptop with a USB stick still in it. That is the whole lesson and it costs nothing.
And if it has already snapped: do not try to hold it in at an angle to get one last read. We see this constantly. Waggling a broken stick in a port shorts the power lines against the data lines, and a cracked board with an intact chip becomes a cracked board with a dead chip. Put it in a bag. Send it.
