Help with CH552G and CH552E projects

Hello. I recently have built your macro pad mini, knob, and macro pad plus. So on the mini it accepts the firmware but nothing works but when the 3rd key is pushed it goes into boot loader mode. On the knob the firmware flashes and it appears to be working but in windows it keeps saying device is not recognized and disappears and reappears multiple times. Lastly, on the macro pad plus it is stuck in a boot loop, rebooting every second. Please reply because i want to get these to start working. Thank you a lot, Samuel
