That's not good, try taking the DC/DC converter out of the circuit. Something is pulling amperage.

Use a USB 2.0 connector and see what happens, looks like it bypasses all the circuitry and goes directly into the controller.
No it doesn't look closerfzabkar wrote:This one has a different USB pinout

Lol, but you can see it yourself..
USB 2.0 connector pins are interleaved with USB 3.0. This is a fact, I know, I work with them frequently. Recover My Flash Drive :lol: :lol:
Look at his picture, +5v USB 2.0 bypasses all the circuitry and goes directly into the controller. his picture is missing the via's for D+ and D-, but your picture has them..
USB 2.0 GND is on that tiny capacitor.
Some InnoStar controllers do the same thing, they isolate USB 2.0 from USB 3.0

In my experience if you have a loose connection on the NAND the device will still work but you will get a no media error. Your mileage may varyMinho wrote:jeremyb wrote:Wouldn't it be funny if by removing the NAND chip the controller booted up and we found out it was simply a broken pad under the NAND chip.
Funny, that's my thinking too...
