X-BeenThere: freebsd-multimedia@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Multimedia discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 15 May 2006 02:16:39 -0000 It requires carefulness to buy hardware for FreeBSD. In this case, I always carry a laptop with FreeBSD installed to shop and test all interested products in the shop. In the file "uaudio.c" the matching operation is only by "class" and "subclass": if (id == NULL || id->bInterfaceClass != UICLASS_AUDIO || id->bInterfaceSubClass != UISUBCLASS_AUDIOCONTROL || (usbd_get_quirks(uaa->device)->uq_flags & UQ_BAD_AUDIO)) return UMATCH_NONE; But just as reported on MP3 player and digital camera (umass) these days, NetBSD USB protocol stack has not been robust enough. Only attendant test can ensure what works with FreeBSD. ------------------------------------------------------------------------ From Beijing, China Dmitry Pryanishnikov wrote: > > Hello! > > I'm going to buy an USB audio adapter supported by FreeBSD's snd_uaudio > driver.
