Re: HUB: Bad transfer status: CHECK_SHORT_LANGID_TABLE
I'm running the usb_host_lib example and I have a hub connected with an FTDI device attached to the hub. The usb_host_lib program lists the hub but does not see the FTDI device attached to it. However, I also get this error message: The USB Host Stack currently only supports a single device (i.e., ...

Re: ESP32 Exception Interrupt WDT Timeout
Are you attempting to call "println()` in an ISR (i.e., from the "solx1_timer_systick_puls_cb()"which in turn is called from the timer ISR)? Judging from the log, you have some task calling "solx1_mqtt_cb()", which in turn calls "println()", which in turn takes UART Mutex lock. While the lock is alr...

Re: ESP32的TWAI一直接收不到数据。
没有更多信息很难将问题定位,例如:BobLiang wrote:ESP32的TWAI一直接收不到数据
- 使用 ESP-IDF 哪一个 release 或 哪一个 commit ID
- 有没有跑过 twai_self_test 实例。Self test 能测试 ESP32 与 PHY 连接有没有问题
- TWAI 运行时,请检查 Receive Error Counter 有没有增加

Re: can't compile using latest master version
Could you run "git status" on esp-idf to double check that all submodules are up to date as well?

Re: Example "msc": crash HUB: Short device descriptor transfer failed
@Emanuel Martins
Just to clear things up. Are you using ESP-IDF natively (i.e., did you install following the IDF Getting started guide)? Or did you install via another method (e.g., VSCode Plugin, Arduino, Platform IO)?

Re: Example "msc": crash HUB: Short device descriptor transfer failed
Nope, copying the MSC example folder from master won't work, you need to update the entirety of ESP-IDF to the master version (I'm assuming you're new to git?) You can use git to checkout ESP-IDF to master as follows: Open the ESP-IDF Command Prompt Navigate to your ESP-IDF directory using the comma...

Re: ESP32-s3 usb msc电脑不能识别
能跑一下 usb_host_lib example 吗?如果结果也是一直等待链接的话,有可能是引脚或电路的问题。

Re: Example "msc": crash HUB: Short device descriptor transfer failed
There were multiple USB Host issues that were fixed on master but haven't been backported to release v4.4. Please try again on master (commit 022fc12 or later).
