Hey gang,
So I got this USB IR port and remote bundled with my DVB card. I'd kinda
like a generic IrDA port to use with my phone and iPaq, so I'm wondering if
I can use this one.
What worries me is that it comes up as a USB HID mouse and keyboard device,
which is kinda cool for use with the remote, but I don't know if that'll let
me use it with the IrDA stack. I get the vague impression from some Googling
that the HID stuff is just a layer on top of the standard IrDA stuff that
the hardware already does, and Linux might be able to talk to both at the
same time. *attempts to wave hands intelligently*
I've popped lsusb -v output for it at the bottom of this mail. Here's what
/var/log/messages says:

Hoping someone groks IrDA and stuff like this - I've never really played
with it much. :-)
Thanks,
- Jeff
