Brand new SB2240 DEAD.

[mWachu]

So i just bought SB2240 directly from BTT site, unboxed it and plugged straight to the USB cable remembering to put the 5V jumper on. I wanted to enter the DFU, but nothing is happening after holding the BOOT and clicking the reset button. My POWER and STATE LEDs are all the time ON. No matter what.

Tried several PCs including my rPi, several cables. No luck so far.

It seems like it attempts to connect, but according to dmesg there is something nasty going on:

Any suggestions?
