I have previously successfully modified Henry's patch for various i2c remotes. However it no longer works, because of this change where the probing was done: Part of Henry's patch: <snip> c.adapter = adap; for (i = 0; -1 != probe[i]; i++) { c.addr = probe[i]; + + if (c.adapter->id == I2C_HW_SAA7134 && probe[i] == 0x0b) { + /* enable ir receiver */ + buf = 0; + if (1 != i2c_master_send(&c,&buf,1)) + dprintk(1,"Unable to enable ir receiver.\n"); + } rc = i2c_master_recv(&c,&buf,0); dprintk(1,"probe 0x%02x @ %s: %s\n", probe[i], adap->name, <snip> The new i2c setup: <snip> for (i = 0; -1 != probe[i]; i++) { msg.addr = probe[i]; rc = i2c_transfer(adap, &msg, 1); dprintk(1,"probe 0x%02x @ %s: %s\n", probe[i], adap->name, (1 == rc) ? "yes" : "no"); if (1 == rc) { ir_attach(adap, probe[i], 0, 0); break; } } <snip> I have a few saa7134 cards with i2c remotes - all of these remotes are completely dead. Does anybody have a suggestion how to make this work, now?
