hi

Have you tried other pins ? I had a successful results with SCL/SDA on a D32 Pro

#define DP_P0  SCL
#define DM_P0  SDA

[gdanov]

yes, I started with them. Also tried S2, no luck too. Keyboard power led lights on, so at least that's right.

[gdanov]

increased the log level, now I get

depending how I connect the signal wires (btw which pin goes to D+/-?) no message that usb was detected

[gdanov]

with level shifter connected like here https://cdn.sparkfun.com/assets/learn_tutorials/2/3/8/5/TXS01018E-Assembly2.jpg I see the led blink rapidly, but still Ack = 0

[tobozo]

Reminder: only USB 1.0 devices will work with this library.

I assume you read the documentation and have already verified this important detail, if the keyboard and mice you try aren't in the supported list and their status is unknow, please provide their respective USB PIV/VID.

with level shifter connected

Level shifter will only make things worse with an esp32, it isn't needed.

Looking at the esp32 pinout, the pins you know for sure aren't pulled up/down are:

2, 4, 13, 15, 25, 26

So if SDA/SCL didn't work, you can still try with {2.4}, {4,2}, {13,15}, {15,13}, {25,26} and {26,25}.

It's worthless to try other combinations, the bitwise hack allowing USB1.0 emulation on ESP32 creates a situation where the "distance" between D+ and D- can't exceed 8 (i.e. using pins {4,13} will never work because 13 - 4 = 9).

[gdanov]

Thanks. I wasn't aware it's strictly usb 1.0 only. I guess this is the problem.
