Zero3w usb on 40pin GPIO

#1

Hi everyone
Accroding to the documentation

By default, Pin-27 can be configured in software for functions such as GPIO4_B2 (see 40-Pin Pinout), while the USB2_HOST2_DP signal is not activated on the hardware. Pin-28 can be configured in software for functions such as GPIO4_B3 (see 40-Pin Pinout), and the USB2_HOST2_DM signal is also not activated on the hardware. To change these pins to USB functions, please follow the steps below to modify the reserved resistors:

After modify the resistors, I still cannot get the usb on gpio to work, at least it fails to detect a device. Do I need to do anything else to let the USB work?

Have the resistors been modified according to the documentation description? If so, please take a photo of your modifications.

Oh I find that I was too careless. I soldered the wrong GPIO pins, the resistor configuration was good. Now the USB is working fine.
