I made a small test app that reproduces the issue with a single project. Maybe its some weird sdkconfig.

Hi, I am trying to integrate the 'console' example into my project. I can compile the example, just fine. But when I copy paste the code into my project, I get this error: undefined reference to esp_vfs_dev_cdcacm_set_rx_line_endings I've hit these isssues before, and usually they are resolved by fi...

I also just tried this setting: CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP=y "Try to allocate memories of WiFi and LWIP in SPIRAM firstly. If failed, allocate internal memory" and tried bumping this setting: -CONFIG_SPIRAM_MALLOC_RESERVE_INTERNAL=32768 +CONFIG_SPIRAM_MALLOC_RESERVE_INTERNAL=64768 No diffe...

I just enabled external SPI ram on my ESP-32S2 Saola, and it is causing wifi init to fail with a 'no memory error'. I've made the change in the Visual Studio Code config editor, and it appears to change this line: CONFIG_ESP32S2_SPIRAM_SUPPORT=y but also automatically changes these lines: -CONFIG_ES...

You can also try my library, which is a bit friendlier to use IMO:

Yes! found the issue. When I open the bulk endpoint the usb device address is no longer zero. I needed that number to be dynamic. Totally overlooked that. hcd_pipe_config_t config = { .callback = pipe_isr_callback, .callback_arg = (void *)port, .context = NULL, .ep_desc = use_ep0 ? NULL : ep, .dev_a...

chegewara, I really apreciate your help. Were you able to get Bulk endpoints working? Whenever I try to initiate a transfer the pipe goes into a halted hcd_pipe_state and reports a generic error. Also, I took your code and made a libusb inspired API for hcd. You can see it here. https://github.com/c...

chegewara,

any chance you could post your USB host code? It would be a great great help!
