Nope because again it's a USB B-connection. B connections are device socke
ts, A connections are hub/host sockets.
The +5V USB power goes from A to B, so trying to charge something from a B
plug would be like plugging two DC-in jacks together and trying to charge o
ne device--it just doesn't make any sense.
To charge your HD3 you'll have to use the stupid mini-dock connector and th
en either a 5V USB cig lighter adapter (or other 12VDC input adapter) and c
onnect a USB cable from there to the mini-B on the mini-dock. However cons
idering you have to use the mini-dock on the HD3, it's much better to use a
6V cig lighter adapter and plug into the DC-in jack on the mini-dock inste
ad, as it charges much faster and is where it's actually supposed to get po
wer from. It can be powered/charged by the USB mini-B connection alone but
this is not recommended and it will take much longer to charge as well.
The mini-dock on the HD3 makes charging in-car impractical as it's stupid l
ooking and awkward; and you really don't want to lose or damage that thing
or you'll have no way to transfer to it or charge the player. I have an HD
3 (actually two of them) and I don't get for the life of me why they didn't
put a separate DC-in jack and mini-B connector right on the player (they d
id do this on the HD5 though).

Can you use the XA-300 to charge a USB music player? like a sony network wa
lkman HD3?
-------------- Original message -------------- From: Roland M <mdx400@hotma
il.com>
The USB port on the XA-300 is a device end, with a USB-B plug. It doesn't
support connecting other devices as a host (which would have a USB-A plug l
ike on a computer). Instead the XA-300 functions as a USB sound card (actu
ally appears as "USB Speakers" with a Burr-Brown D/A in XP, IIRC). You can
't plug other devices into it. It would be like plugging in an HDD into a
printer or a thumb drive into wireless network adapter, lol. Roland M.> Sub
