Have installed the latest nightly build for reasons outlined in another bug report.
Noticed in this version (0.5.0-git-e6c8d58) that have you use triggers it misses data. I was trying to see 5 bytes of Serial data data at 9600 from a AtMega2560 & AtMega328P. Sample rates and times where Varied from KHz to MHz, but data always lost. Remove triggers and data displayed as expected.
Whilst I didn't look I don;t seem to remember this occurring with previous versions (also at 9600 for 1-Wire development)
Sounds like a bug in the driver. Which acquisition device did you use?
