Linksys WUSB6100M

Linux support
QCA9377 USB support would appear to be in-kernel for ath10k. Whether or not it actually works (reliably or reasonably) for this dongle is questionable.

The driver itself warns - ''' WARNING: ath10k USB support is incomplete, don't expect anything to work! '''.

At a bare minimum, you will need the firmware and board data for this specific device.

For more information, see This LWML post, which is the (RFC) patch adding USB support to ath10k (tested specifically with a WUSB6100M) which links to their GitHub repository with some firmware dumps.
