Perhaps a bit of topic on this forum, but Silabs cannot help me unfortunately, so I thought let’s give it a try.
I bought a cheap ESP32 dev kit, and installed the CP210x drivers for it (found here: CP210x USB to UART Bridge VCP Drivers - Silicon Labs). The Silabs chip on the device has the following information:
CP2102
DCL00X
1806+
No matter what I try, I cannot get the device to work. I keep getting “The device cannot start (Code 10)”. Reinstalling drivers, rebooting, trying different USB HUBS and cables, trying the windows 7/8 drivers, nothing works.
I can get the ESP32 to work on my Ubuntu system, with the drivers that come pre installed with Ubuntu.
Device manager:
So the device VID is 10C4 and the PID is EA60, so I believe I should be able to use the normal drivers. Any ideas of what I can try to get it to work?
