USB stops working after Windows host computer sleep

asafteirobert commented 1 year ago

Board

LOLIN S2 mini

Device Description

LOLIN S2 mini with ESP32-S2FH4 chip

Hardware Configuration

LOLIN S2 mini with some buttons attached to IO pins, connected to a Windows PC through USB.

Version

v2.0.8

IDE Name

Arduino IDE

Operating System

Windows 10 21H2

Flash frequency

40MHz

PSRAM enabled

no

Upload speed

921600

Description

Reproduction steps:

Setup: LOLIN S2 mini connected to a Windows PC through USB
Load the examples\USB\Keyboard\KeyboardMessage\
Pressing the button types the message correctly.
Put Windows to sleep using Start->Power->Sleep
Wake up Windows
Pressing the button no longer types the message.

It appears the whole USB ends up in a broken state as uploading to the port(which still shows as connected) is no longer possible. Trying to access the debug serial port gives Error 31 "A device attached to the system is not functioning". Unplugging the USB cable USBLogView shows the USB Composite device, USB Input Device and USB Serial Device being unplugged. Reconnecting the USB cable (and thus also resetting the device) makes the sketch and upload port work again.

What I tried:

USB CDC On Boot Enabled or Disabled
Calling USB.usbAttributes(TUSB_DESC_CONFIG_ATT_REMOTE_WAKEUP); before USB.begin();
Disabling "Allow the computer to turn off this device to save power" on the HID device.

I can confirm that USB power is not turned off.

Good day, I I was wondering if you found a solution to this problem? I'm encountering the same issue with the ESP32-S3-WROOM-1 module.

Did you try this?

USB.usbAttributes(TUSB_DESC_CONFIG_ATT_SELF_POWERED | TUSB_DESC_CONFIG_ATT_REMOTE_WAKEUP);

Hi, I'm having this issue too and the fix in the above post doesn't seem to work. I think TUSB_DESC_CONFIG_ATT_REMOTE_WAKEUP is about the mouse's ability to wake up the computer, not the other way around. I'm using an ESP32-S2-DevKitM-1U.

I'm having the same issue. It's not an ESP32-* issue, but rather an issue with the TinyUSB library. I tried a different project on an RP2040 board, which also uses TinyUSB and exhibits the same behavior. You should open a bug ticket for that project as well.

I actually remade my project on an rp2040 and this issue went away, but I'm using the mbed os core, not the arduino-pico core. Does the mbed os core also use TinyUSB?

MRezaNasirloo commented 5 months ago

I couldn't find any reference to TinyUSB in the mbed project. Do you use USB CDC in your project? Also, do you use USB power or a dedicated 5V voltage?

When the PC goes to sleep, the 5V is not disconnected, leaving the cdc usb stack in a broken state. I found out that if you use a 5V source from the PSU, the MCU will shut off on PC sleep and turn on again on wake up, It's a workaround, not a solution.
