Not without providing at least 8ma VBUS power and a Mini-AB connector it isn't. Instead, it provides 0mA VBUS power and a Mini-B connector. :) The Tahvo chip has a USB transceiver that's not really OTG-capable. But it can do "dual role", that is it can switch between host and peripheral modes ... which is an OTG thing, if done the OTG way. Which means initial role sensing via the cable connected to the Mini-AB port, and HNP support to automatically switch roles later. > I got the network to work.

It's a standard OTG descriptor, but the device shouldn't be putting one out since it's not OTG-conformant. - Dave ------------------------------------------------------------------------- Take Surveys.
