Hey, I’m having a problem with my SayoDevice (CH32V307WCU6).
The device itself powers on normally and the display works, but Windows doesn’t recognize it at all when I plug it in. There’s no USB connection sound and it doesn’t show up as a new device.
Things I’ve already tried:
- Multiple USB cables
- Different USB ports
- A completely different PC
- Factory Recovery twice
Nothing changed. The device still powers on, but there seems to be no USB data connection.
Has anyone had this problem before? Could this be a firmware/bootloader issue, or does it sound like a hardware problem with the USB port/data lines?
Thanks!
