Folks not running PW-3, 5.4.7.1 are missing a kernel module.
Which is why those other kernels are not recognizing the hot plugging of the Amazon dongle.

Since its GPL - for the adventurous - attached.

Non-technical folks stop reading here, even stop thinking of trying this . . . .
You need command line access to your i.MX6 device (I don't recall if the PW-1 is running kernel 3.0.35) and it must be running the same kernel version (uname -a) as shown above.
Download to top of visible USB root -
then, from the command line -
cd /lib/modules
tar -xzf /mnt/us/vv-mod.tar.gz
The path to the *.ko is contained in the tar-ball, it will only un-compress to the proper kernel build tree.
You will probably have to manually insert it (insmod), since I am not including the updated auto-magic-loading files for modprobe (or udev, which uses modprobe data).
Do not be surprised if it fails to load (or loads and does nothing) - we might need the newer kernel build from 5.7.4.1 also.
- - - - -
At this point (after insmod'ing the driver) the kernel should recognize the audio dongle and say something about it in dmesg.
There are probably a lot more requirements to be met to make vv work - -
But the USB-OTG module probably has other uses.
(At least you would think so, there have been requests for it for years.)
we (readers and devs) will putter around with this as time is available.
