Currently I am using WSL2 Ubuntu to build a custom WSL2 with moxa Linux driver source from MOXA website, and enable other USB serial controller devices in the custom kernel configuration.

git clone https://github.com/microsoft/WSL2-Linux-Kernel.git --depth=1 -b linux-msft-wsl-6.6.y
mkdir ~/moxa
wget https://cdn-cms-frontdoor-dfc8ebanh6bkb3hs.a02.azurefd.net/getmedia/c7a1d4ee-ff6f-46fe-b707-e6e2c6fcc152/moxa-uport-1100-series-linux-kernel-6.x-driver-v6.0.tgz
tar -xvzf moxa-uport-1100-series-linux-kernel-6.x-driver-v6.0.tgz.tgz
cp mxu* ~/moxa
cd ~/WSL2-Linux-Kernel
mkdir wsl
cp Microsoft/config-wsl wsl/linux.config
sudo ln -s ~/WSL2-Linux-Kernel /usr/src/$(uname -r)
sudo ln -s ~/moxa/mxu11x0/driver/m* /usr/src/$(uname -r)/drivers/usb/serial/
sudo ls -l /usr/src/$(uname -r)/drivers/usb/serial/m*
sudo nano /usr/src/$(uname -r)/drivers/usb/serial/Kconfig

config MOXA_UPORT_11X0
    tristate "USB Moxa UPort 11x0 Driver"
    depends on USB_SERIAL

sudo nano /usr/src/$(uname -r)/drivers/usb/serial/Makefile

obj-$(CONFIG_MOXA_UPORT_11X0) += mxu11x0.o

After repairing some incompatible function definition for mxu1_break() in mxu11x0.c:

Building the custom kernel...

My intent is to use the usbipd tool from USBIPD-WIN project to attach the moxa device to WSL2.

I have no issue to see ttyUSB* when loading mxuport driver for the Moxa Uport 1618 device:

How can I solve this issue?

static int mxu1_download_firmware(struct mxu1_device *mxdev,
	unsigned char *firmware, unsigned int firmware_size)
{
	int status = 0;
	int buffer_size;
	int pos;
	int len;
	int done;
	__u8 cs = 0;
	__u8 *buffer;
	struct usb_device *dev = mxdev->mxd_serial->dev;
	struct mxu1_firmware_header *header;
	unsigned int pipe = usb_sndbulkpipe(dev,
		mxdev->mxd_serial->port[0]->bulk_out_endpointAddress);

	
	buffer_size = MXU1_FIRMWARE_BUF_SIZE + sizeof(struct mxu1_firmware_header);
	buffer = kmalloc(buffer_size, GFP_KERNEL);
	if (!buffer) {
		dev_err(&dev->dev, "%s - out of memory\n", __FUNCTION__);
		return -ENOMEM;
	}

	memcpy(buffer, firmware, firmware_size);
	memset(buffer+firmware_size, 0xff, buffer_size-firmware_size);

	for(pos = sizeof(struct mxu1_firmware_header); pos < buffer_size; pos++)
		cs = (__u8)(cs + buffer[pos]);

	header = (struct mxu1_firmware_header *)buffer;
	header->wLength = cpu_to_le16((__u16)(buffer_size - sizeof(struct mxu1_firmware_header)));
	header->bCheckSum = cs;

	dbg("%s - downloading firmware", __FUNCTION__);
	for (pos = 0; pos < buffer_size; pos += done) {
		len = min(buffer_size - pos, MXU1_DOWNLOAD_MAX_PACKET_SIZE);

		status = usb_bulk_msg(dev, pipe, buffer+pos, len, &done, 1000);

		if (status)
			break;
	}

	kfree(buffer);

	if (status) {
		dev_err(&dev->dev, "%s - error downloading firmware, %d\n", __FUNCTION__, status);
		return status;
	}

	dbg("%s - download successful", __FUNCTION__);

	return 0;
}

Even changing the timeout value from 1000 ms to 5000 ms in usb_bulk_msg() call in mxu1_download_firmware() doesn't help.

The "vhci_hcd: urb status -104" error typically indicates a problem with USB communication in a Linux environment. This error can occur when there are issues with the USB device connection, such as a timeout or disconnection.

When comparing both test cases, it looks like:
(1) vhci_hcd is unable to determine the speed of UPort 1150: "vhci_hcd: vhci_device speed not set" from vhci_hub_control() call
(2) vhci_hcd is able to determine the speed of UPort 1610-8: no ""vhci_hcd: vhci_device speed not set" issue
