What is the operating current of the thumbDV dongle?

Ko Seokki

It does not work on some tablet PCs.

Can I use a USB hub with external power?

Micro USB - OTG - ThumbDV dongle Can this be a problem?
The existing tablet was not used in USB 2.0 B type - OTG,
The tablet I was using was available on the USB 3.0 C type -OTG.
Is USB speed a problem? Is USB current a problem?
