QCA9377 USB adapter: Bluetooth works but WiFi doesn't

I have a QCA9377 USB adapter. When I plug it to the laptop, it gets enumerated as a USB host with two devices: the BT device and the WiFi device. The BT device works, but the WiFi device doesn't. The ath10k_usb driver is not loaded and no radio is created. When plugging the device this is what dmesg shows:

I have tried manually loading the driver (modprobe ath10k_usb) and the driver loads but it still doesn't work.

linux-firmware is installed, and I can see firmware files for the QCA9377 chipset:

/usr/lib/firmware/ath10k/QCA9377/hw1.0/board-2.bin.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/board.bin.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/firmware-sdio-5.bin.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/notice_ath10k_firmware-5.txt.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/notice_ath10k_firmware-6.txt.zst
/usr/lib/firmware/ath10k/QCA9377/hw1.0/notice_ath10k_firmware-sdio-5.txt.zst

rfkill does not show hardware blocks either (wlan dev ID1 is the laptop onboard WiFi):

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked
 6 bluetooth hci1   unblocked unblocked

Why is the driver not loading/working?

Try the usb_modeswitch package.

Thanks for the suggestion.

AFAIK the modeswitch package is for when you need to change the configuration for a USB device. That's not the case here, I have a hub with two devices simultaneously, but one of them is not getting the driver loaded. Anyway gave it a try and as expected, it made no difference.
