Dear friend,No, not while charging. And yes, the computer recognizes it on usb as storage mode, but not as DAC mode. Also, is there a way to not charge the X5 II while docked in the K5? I think that will mess up the battery as well... I use it a lot on the k5, so the X5 II is always fully charged...
I need to confirm more information of the collection:
1. When collecting the X5II directly to the computer, both storage and DAC mode work well?
2. When docking the X5II in the K5 and collecting to the computer with the square USB cable comes with the K5, only storage mode works well?
Please check whether you have installed the DAC driver and switch the USB mode to DAC as well. Then you can select X5II as sound device in your computer.
When the X5II is docking in the K5, power is supplied to the device as follows:
1. While the device is charging
Because the computer USB port has limited current capacity, the battery is given priority for part of the charging current while the rest powers the device directly. But if the current draw by the device is high, the battery participates in powering the device as well. Hence, both the battery and the USB port take part in powering the device while the device is charging.
2. After the battery is full
Because there is no need to charge the battery anymore, the USB port would power the device directly. The battery would neither be charged nor discharged.
In summary of the above, the powering scheme of the X5II ensures that the battery may be fully charged while at the same time guaranteeing proper function of the device. Finally, the battery will be at rest after it is fully charged, thus guaranteeing extended battery life.
