Ytai, Just tried on a different PC. No luck. Same issue happens. Unknown USB Device in non-bootloader mode. Cannot read app firmware in ioiodude when in this mode. (connected the IOIO in "A" position with no external supply) About the USB hub in the middle, I had already verified that before. With or without it same issue happens too. I don't know what to do anymore, this is so frustrating...
