OK -- I give up.... I'm trying to get the LPBB I2C driver working on my 3.2-stable machine, CVSUP'd earlier today... I have tried about a zillion and two different config file combinations, and can not get it to work. The relevant parts of the config file are: device ppc0 at isa? port? tty irq 7 controller pcf0 at isa? port? irq 5 controller iicbb0 controller smbus0 device smb0 at smbus? controller ppbus0 #device lpt0 at ppbus? #device ppi0 at ppbus? device lpbb0 at ppbus? controller iicbus0 device iic0 at iicbus? device iicsmb0 at iicbus? (.....As you can see, I took out the printer driver and the geek port during this hair-pulling session -- those two devices vanish, but nothing else appears.) The dmesg chunks that show up about this are: ppc0 at 0x378 irq 7 on isa ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode ... pcf0 at irq 5 on isa ... pcf0: <PCF8584 I2C bus controller> iicbus0: <Philips I2C bus> on pcf0 addr 0xaa iicsmb0: <I2C to SMB bridge> on iicbus0 smbus0: <System Management Bus> on iicsmb0 smb0: <SMBus general purpose I/O> on smbus0 iic0: <I2C general purpose I/O> on iicbus0 It seems to see the PCF8584 just fine, but it refuses to put the parallel port I2C interface in... If I remove the "controller pcf0" line, all of the I2C drivers disappear. Any ideas? --Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
