Failed to get string descriptor 0xC8: Input/Output Error

Once uclogic-probe tries to get 0xC8 descriptor from XP-PEN G430S_B, it makes the device change USB id to 28bd:1227 and stop working. The device LED is lit up constantly after that and it doesn't send anything even when the pen is approaching.

To note: This also happens to XP-Pen CT640 but blinks when sudo uclogic-probe 3 13 | uclogic-decode is executed. Same error as above.

sudo uclogic-probe 3 13 | uclogic-decode output:
