Dual USB Setup Not Working on GPIO 2,3 and GPIO 4,5 - LV Code Commented Out

[zoushiyin]

Hello,

The following code is from the [https://github.com//issues/65#issuecomment-2519971280 branch,](branch: https://github.com/No0ne/ps2x2pico/tree/65-built-in-software-usb-hub-on-pio-sm), a dual USB version. Why is the LVOUT part commented out? Additionally, when I compile it for a dual USB setup on GPIO pins 2, 3, and GPIO pins 4, 5, the board does not work. I have followed the schematic from #65 (comment) to design my PCB for the Pico Zero version.Could you help analyze what might be causing this issue? Thank you very much.

int main() {
set_sys_clock_khz(120000, true);
board_init();
printf("\n%s-%s\n", PICO_PROGRAM_NAME, PICO_PROGRAM_VERSION_STRING);

//gpio_init(LVOUT);
//gpio_init(LVIN);
//gpio_set_dir(LVOUT, GPIO_OUT);
//gpio_set_dir(LVIN, GPIO_OUT);
//gpio_put(LVOUT, 1);
//gpio_put(LVIN, 1);

tuh_hid_set_default_protocol(HID_PROTOCOL_REPORT);
tuh_init(0);

pio_usb_configuration_t pio_cfg = PIO_USB_DEFAULT_CONFIG;
pio_cfg.pin_dp = 2;
tuh_configure(1, TUH_CFGID_RPI_PIO_USB_CONFIGURATION, &pio_cfg);
tuh_init(1);

pio_usb_host_add_port(4, PIO_USB_PINOUT_DPDM);

kb_init(KBOUT, 0); //KBIN);
ms_init(MSOUT, 0); //MSIN);
