When insert or remove U disk, WT2003S will automatically return data to make prompt. Low 4BIT of
return value stands for the status of PC connection (BIT3), U disk (BIT2), SD card (BIT1) and
SPI-FLASH (BIT0).
0 stands for existence; 1 stands for nonexistence.
For example:
0x01: without PC connection (BIT3=0), without U disk (BIT2=0), without SD card (BIT1=0), with
SPI-FLASH (BIT0=1).
0x07: without PC connection (BIT3=0), with U disk (BIT2=1), with SD card (BIT1=0), with SPI-FLASH
(BIT0=1).
This version does not support SD card, so the second bit is 0.
