<span style=" font-family:'calibri'; font-size: 12pt;">Hi Jef,<br/>
<br/>
Thank you to both you and Giorgio. The second powered USB hub works consistently.</span><p><span style=" font-family:'calibri'; font-size: 12pt;">One final request. Could you look at the attached log file and tell me if it contains records of valid dive data?</span></p><p><span style=" font-family:'calibri'; font-size: 12pt;"><br/></span></p><p><span style=" font-family:'calibri'; font-size: 12pt;">
</span><span style=" font-family:'calibri'; font-size: 12pt;">Diving Log 6.0 appears to download all 46 dives but after a successful download imports 46 blank dives with no profile and the date and time of download.</span></p><p><span style=" font-family:'calibri'; font-size: 12pt;"> </span></p><p><span style=" font-family:'calibri'; font-size: 12pt;">Subsurface downloads fine.</span></p><p><span style=" font-family:'calibri'; font-size: 12pt;"> </span></p><p><span style=" font-family:'calibri'; font-size: 12pt;">I just want to make sure the download is OK before going back to Sven.</span></p><p><span style=" font-family:'calibri'; font-size: 12pt;"> </span></p><p><span style=" font-family:'calibri'; font-size: 12pt;">Thanks again.</span></p><p><span style=" font-family:'calibri'; font-size: 12pt;"> </span><span style=" font-family:'calibri'; font-size: 12pt;"><br/></span></p><p><span style=" font-family:'calibri'; font-size: 12pt;">
