Nope, via usb on Debian or usb on a NSLU (2.6p3, I upgraded it.) , one
of DS2423 devices does not appear.
For the device which is discovered, one difference is that with
Debian+USB, I can read the counter via python, using the NSLU I cannot.
On Debian+Serial, I can see and read both devices.
Has anyone else got multiple DS2423 devices on USB ?
Any ideas ?
I have another DS2423 somewhere, I'll find it and add it to the bus to
see what affect it has.
