These take longer than memory cards because the operating system has to find a driver and load it for each Thumbdrive the first time the computer sees the Thumbdrive. Succeeding reads take less time but are still slower than memory cards because the drive has to be installed. There is one other problem, which is mostly with “Cruzer” thumbdrives. These seem to have programs on them that automatically start and run, which totally blocks my computer from reading the flight log. So, please, NO Cruzers. Instead get an ordinary cheap small thumbdrive and use it. 3- 3 ½ inch Floppy Disks. Although pretty obsolete, I can still read them. 4– Direct downloads from Loggers. A - I have the hardware and software to download the older Cambridge Model 10, 20, or 25 loggers. B – I have the hardware and software to download Volksloggers with the RJ-11 connector. C – EWA Microrecorders have a USB connection and behave like a thumbdrive ." -T8 |

I have a small converter that looks like a normal USB memory stick, with a tiny slot in the end for a uSD card (I use this for turning in FLARM log files). The combo (adapter plus uSD card) draws 100ma, which is the max our adapter sources. What it needs all that power for I have no idea... Your mileage may vary ! Best Regards, Dave PS: In windows device manager, switch to connection view, and you can see the USB current for each connected device. No need for breakout cables... You don't need to be in connection view do you? Its the easiest way to find the hub controlling your device, which is where you need to look at the power. Anyhow this does not work in a virtual machine like I am running. My God, people still run Windows on native hardware? I keep mine locked tightly is a safe container on the shelf and only open it when needed. Depending on *which* virtualization scheme you are using and its USB support, it may work. USB doesn't work in free VirtualBox for example... Darryl |

Best Regards, Dave PS: In windows device manager, switch to connection view, and you can see the USB current for each connected device. No need for breakout cables... I opened Device Manager, located my USB memory stick in the USB controller list, opened Properties, but don't see power or current listed in any of the tabs. The Generic hub did have a Power tab, but it showed the requirement for the attached device (auxiliary display), not actual current. Can you be more specific on which USB to look at, and where in the Properties? -- Eric Greenwell - Washington State, USA (netto to net to email me) - "Transponders in Sailplanes - Feb/2010" also ADS-B, PCAS, Flarmhttp://tinyurl.com/yb3xywl Start with "View by Connection". Locate the USB hub controlling your device. Look at properties, power tab... This shows the max current negotiated (max to be provided by USB host), not the instantaneous actual current. Hope that helps, Best Regards, Dave |
