I assume we're talking about the DS2482-800 -- the 8 channel i2c-based bus
master.

The fact that a reboot doesn't fix the problem takes in issue out of owfs
(which should be entirely reset by a reboot) and to the hadware (which
might need a power cycle to fully reset).

The datasheet talks about a "Device Reset" command (0xF0) that completely
resets the device. We do that on startup, so clearly that's not sufficient.
There must be some enumeration that's done on power-up.

So, I'm at a loss. But how about obvious things -- anything in the system
logs? Possible power problems? Marginal bus design?
