Lsusb sees the dongle without any issues but I can't identify what

What does lsusb exactly print?
I thought the issue may have been fixed with deleting the network
definition for the wifi and recreating it with the new dongle,
but having used the wifi interface for several minutes it
disconnected and reconnected again, which is better than what it
was previous as it was unusable. The lsusb output is below, but
when I ran this originally, before the device was usable, the
section that tells me the manufacturer name wasn't displaying,
but like originally I can't see anything obvious that tells me
exact chipset.
Usually the ID 0846:9072 is enough. You can check the LHDB with
<https://linux-hardware.org/?id=usb:0846-9072>. I see one LHDB probe
with this device. It is shown as "working", but doesn't give the
name of an in-kernel driver, so either may be using a very new
(possibly buggy) in-kernel driver or a 3rd party driver. "inxi
-Nzxx" should tell you what driver is being used.
From the Linux Kernel Driver Database:
<https://cateee.net/lkddb/web-lkddb/MT7925U.html>: "This adds support
for MT7925-based wireless USB devices, which support operation at
6GHz, 5GHz, and 2.4GHz IEEE 802.11be 2x2:2SS 4096-QAM, 160MHz channels."
Thanks George, that module looks like it might be it. The
dongle/router is a tri-band 802.11be device with 2.4GHz, 5GHz and 6GHz
bands. I've tried a modprobe of that module but at the moment it
doesn't seem to be doing anything, I'm trying to see if it is actually
installed.

Just as a matter of interest is there anything I can do to
increase the connection speed? At the moment the device is
running at 29.2 Mbps but it is capable of connecting at up to 6
Gbps.
While writing this email the device has disconnected and
reconnected a number of times, which then also causes all the
active firewall zones to also bounce.
[...]
Look for details with journalctl. You may need newer firmware.
Some systems have buggy USB, or a mix of USB2 and USB3 ports.
Under windows the device has a driver supplied with it to enable the
device, which also lights a light on the side of the dongle and it
connects at 2882/2882 Mbps on the 6GHz channel.
I've issued the command inxi -Na -E and it has given me the following
output, does this mean there is no driver available for it? This
display is after issuing a modprobe mt7925u and a depmod -a.

regards,
Just following up on this if modprobe mt7925u doesn't appear to do
anything, and the firmware for the 7925 chipset is installed and support
for that chipset appears to be in the kernel, how do I load the kernel
module as the kernel config appears to be specifying that the support is
modularized rather than static.
regards,
