I'm doing my first big sync (around 1Gb) on USB using 2.0b3. I'm doing it mainly as a test of 2.0b3 as I realised I hadn't tried any big syncs with it yet (and I usually had problems with big syncs on 1.x).

I'm now part of the way through (can't tell how far, as the overall progress bar doesn't work) and things aren't going too well.

It started out well, but after half an hour I started to see problems very similar to those I had on 1.x of emplode. What happens is emplode starts to pause part of the way through uploading a tune. When it does this the player is outputting the following on the serial port:

endpoint stall(clear stall on ep5)
endpoint stall(clear stall on ep4)
endpoint stall(clear stall on ep5)
endpoint stall(clear stall on ep4)

This carries on for 20 minutes or so before emplode gives up and outputs "blah could not be synchronised., Data error (cyclic redundancy check). (error 0x80070017)" in the warning list. Emplode 2.0b3 is better than 1.x in that it manages to carry on, in 1.x it would do this to a couple of tunes and then eventually stop dead.

This has happened on about eight tunes so far.

There was another problem, about an hour in I got a whole bunch of "connection timed out 0x8004003e" warning messages.
