I'm not sure why it's not able to detect the audio formats for your USB device. Try also-capabilities --help.
alsa-capabilities --help give just the help of the command
Code:
pi@moode-pt:~ $ alsa-capabilities -h
Usage:
alsa-capabilities [ -l a|d|u ] [ -c <filter> ] [-a <hwaddress>] [-s] [ -q ]
Displays a list of each alsa audio output with its details
including its hardware address (eg. `hw:x,y').
The list may be limited by applying one or more options with
arguments, for the type of output (`-l' or `--limit'), the name of
the card and/or output (`-c' or `--customfilter'), and/or the
hardware address (`-a\ or `--address').
The `-s' or `--samplerates' switch turns on the detection and
display of the supported samplerates per encoding format for each
output.
-l TYPEFILTER, --limit TYPEFILTER
Limit the interfaces to TYPEFILTER. Can be one of
`a' (or `analog'), `d' (or `digital'), `u'
(or `usb'), the latter for USB Audio Class (UAC1
or UAC2) devices.
-c REGEXP, --customlimit REGEXP
Limit the available interfaces further to match
`REGEXP'.
-a HWADDRESS, --address HWADDRESS
Limit the returned interface further to the one
specified with HWADDRESS, eg. `hw:0,1'
-s, --samplerates Adds a listing of the supported sample rates for
each format an interface supports.
-q, --quiet Surpress listing each interface with its details,
ie. only store the details of each card in the
appropriate arrays.
-j, --json Surpress normal output but create json formatted
output instead.
-n, --nocolor Supresses colorized output.
-h, --help Show this help message
