The vendor ID etc. keep being zero, because the SII is not read at all.

I slightly improved the SII error messages and pushed it to YourceForge.
Please try the newest version and also enable the SII_DEBUG macro in
master/fsm_sii.c.

Please power down your device, then set the debug level to 1 and power
up the device and post the logs until the SII error.
