It has a large chip in the middle labeled CONEXANT FUSION 878A 25878-13 E345881.1 0312 TAIWAN It has an audio connector coming out from a chip labeled ATMEL 0242 AT89C2051-24PI It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18) ... 01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 01:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 01:0a.0 0400: 109e:036e (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dfffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 01:0a.1 0480: 109e:0878 (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dffff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18 kernel and the latest v4l-dvb drivers, but it did not work at all. The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers.
