I finally upgraded a zaurus to the current snapshot (Jul 03). I had transferred the sets via cdcef/cdce, though it TIMEOUT'd during several transfers and had to be unplugged/plugged in again. However now that it's upgraded to 4.4-beta, when I do this:
pc% sudo ifconfig cdce0 inet 192.168.10.11 up ...immediately the zaurus console says: pxaudc_read_epN: ep 1, no xfer ...and the pc console says: cdce0: usb error on rx: STALLED cdce0: too many errors, disabling pc is running 4.3-current from ~Jun 10, and the zaurus with its new 4.4-beta. Thanks in advance for any help...
