When i use standard Windows' "remove device" (Vista x64 Ultimate) the light goes off.
However with SafelyRemove 4 (any beta , tested up to 6) it stays on even after ejecting device.
As I said it does not look to be a real problem but I find it really strange that device does not power down with your software.
Yes, it's really strange. We have received messages (and observed it by ourselves) that Vista sometimes does not power off USB devices after safe removal made by the native tool.
Could you send me technical information of the mentioned device? You can find it on the Technical Information tab of the device properties in the program.
