Hi Eikka. Am not familiar with OMAP35xx.
Also don't know, what's the config of EVM (if it uses twl4030 tranceiver or external). Can it play as a HOST which is the case to supply VBUS ? Otherwise external self-powered hub might be needed. -niilo- On Wed, 2009-05-27 at 02:59 +0200, ext Eino-Ville Talvala wrote: > Hi, > > We're trying to get basic USB host mode up and running on a OMAP3530 > EVM, with no success.
