USB Mode

You can boot in USB Mode by shorting the pins tagged with USB/NAND. I think it's some kind of switch between USB and NAND boot modes. You will need the Telechips or the tcctool drivers. You need to modify the .inf files by adding the TCC82x chip using VID=140E and PID=B051.

  Telechips FWDN tool inf

[Telechips]
%USB\VID_140E&PID_B051.DeviceDesc%=VTCDRV.Dev, USB\VID_140E&PID_B051

[Strings]
USB\VID_4102&PID_1032.DeviceDesc="Telechips TCC82xx VTC USB Driver"

  tcctool inf

[Devices]
"TCC82x usb-boot mode"=LIBUSB_DEV, USB\VID_140E&PID_B051

[Devices.NT]
"TCC82x usb-boot mode"=LIBUSB_DEV, USB\VID_140E&PID_B051

[Devices.NTAMD64]
"TCC82x usb-boot mode"=LIBUSB_DEV, USB\VID_140E&PID_B051

These are examples only. I didn't post the entire .inf files.
