Hi, I've been trying to test the ESP32 in WSL with this setup:

Windows 11 pro, build 22579.1 Windows Subsystem for Linux Preview 0.56.2 WSL kernel 5.10.102.1 (no modified) Ubuntu 20.04 over WSL2 usbipd 2.1.0 Powershell 7.2.2 No modified WSL kernel

I attached the ESP32 with usbpid and I get the following by executing $ dmesg

$ dmesg ... [ 1601.184053] vhci_hcd vhci_hcd.0: pdev(0) rhport(0) sockfd(3) [ 1601.185266] vhci_hcd vhci_hcd.0: devid(65542) speed(2) speed_str(full-speed) [ 1601.186392] vhci_hcd vhci_hcd.0: Device attached [ 1601.474405] vhci_hcd: vhci_device speed not set [ 1601.544561] usb 1-1: new full-speed USB device number 6 using vhci_hcd [ 1601.624393] vhci_hcd: vhci_device speed not set [ 1601.694383] usb 1-1: SetAddress Request (6) to port 0 [ 1601.730388] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00 [ 1601.731178] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1601.731886] usb 1-1: Product: CP2102N USB to UART Bridge Controller [ 1601.732491] usb 1-1: Manufacturer: Silicon Labs [ 1601.732918] usb 1-1: SerialNumber: 044718903fe9eb11b63da08787c335f3 [ 1601.735773] cp210x 1-1:1.0: cp210x converter detected [ 1601.739526] usb 1-1: cp210x converter now attached to ttyUSB0

That means that is it working? I have don't have too much knowledge about USBs on Linux and I can't be sure that is working because I tried to flash esp-idf's blink example with '$ idf.py flash' but it says: /dev/ttyUSB0 failed to connect: [Errno 13] could not open port /dev/ttyUSB0: [Errno 13] Permission denied: '/dev/ttyUSB0'

After some research I found a workaround by running $ sudo chmod 0666 /dev/ttyUSB0, so I run again esp-idf flash and I get this output:

$ idf.py flash Executing action: flash Serial port /dev/ttyUSB0 Connecting.... Detecting chip type... Unsupported detection protocol, switching and trying again... Connecting.... Detecting chip type... ESP32

It stays like this like 20 seconds more less and then I get this output:

Serial port /dev/ttyUSB0 Traceback (most recent call last): File "/home/diego/.espressif/python_env/idf4.4_py3.8_env/lib/python3.8/site-packages/serial/serialposix.py", line 322, in open self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK) FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyUSB0'

And if I run usbipd wsl list on powershell, I find that the ESP32 (Silicon Labs CP210x USB to UART Bridge) has been detached.

So, I don't really know if this issue has been resolved and I have a problem in another place or the issue continues and my problem when flashing is because of this issue.

EDIT: I've been curious and I executed again $ dmesg after a flashing try and I got this:

$ dmesg ... [ 1677.796756] vhci_hcd: unlink->seqnum 570 [ 1677.934506] vhci_hcd: urb->status 0 [ 1677.936030] vhci_hcd: unlink->seqnum 571 [ 1677.936450] vhci_hcd: urb->status 0 [ 1677.938238] vhci_hcd: cannot find a urb of seqnum 566 max seqnum 572 [ 1677.939955] vhci_hcd: stop threads [ 1677.970111] vhci_hcd: release socket [ 1677.970491] vhci_hcd: unlink cleanup rx 565 [ 1677.970940] vhci_hcd: the urb (seqnum 565) was already given back [ 1677.971581] vhci_hcd: unlink cleanup rx 567 [ 1677.971932] vhci_hcd: disconnect device [ 1677.982592] usb 1-1: USB disconnect, device number 6 [ 1682.994614] cp210x ttyUSB0: failed set request 0x12 status: -110 [ 1682.996149] cp210x ttyUSB0: failed set request 0x0 status: -19 [ 1682.997934] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0 [ 1682.998765] cp210x 1-1:1.0: device disconnected

UPDATE: I flashed a new blink example (+ serial output) on Windows, attached the ESP32 to WSL and ran $ make monitor on the original blink example on WSL and I got the output from the ESP32! I tried $ make flash but it fails again with this output serial.serialutil.SerialTimeoutException: Write timeout and its deattached, $ idf.py monitor detach ESP32 from WSL too.
