Hello support,

Three unresolved issues are:

1 Battery on DSO Nano V3 does not charge on product arrival.

2 What are the limits on USB power to the Nano?

Nano works fine on Belkin 7 port and Desktop USB power.

Will Nano be damaged if it is connected to USB over voltage charger?

3 Nano PC software appears in My Computer as DSO_NANO_V3.

LG 840G Tracfone does not appear in My Computer when Nano is connected.

LG 840G appears in My Computer when Nano is disconnected.

Software problem possible?

Battery not charging video.

But several of the reviews that I've found report that the charging circuit for the supplied lithium battery is nothing more than a single resistor connected to the 5 volt pin of the USB port.
