Hi *

The i2b bus on my RPI-B isn’t working:

[grapeseed] /usr/src 11:11 am # i2c -sv
dev: /dev/iic0, addr: 0x0, r/w: r, offset: 0x00, width: 8, count: 1
Error scanning I2C controller (/dev/iic0): Device not configured
Scanning I2C devices on /dev/iic0: [grapeseed] /usr/src 11:11 am # i2c -sv -f /dev/iic1
dev: /dev/iic1, addr: 0x0, r/w: r, offset: 0x00, width: 8, count: 1
Error scanning I2C controller (/dev/iic1): Device not configured

Its a bog-standard build with the RPI-B kernel, and a CURRENT about a week old.

Any ideas?
