Hm, this landed in my SPAM box, sorry for the delayed response... It was last tested on 2.6.10 at some length, with the USB-IF test suite using an H2 revB board with an OMAP-1611. Most of the OTG details are not in that driver by the way ... they're in the isp1301_omap driver, which hooks up the OTG controller to an external ISP 1301 transceiver. However, newer silicon changed some of the OTG transitions incompatibly, and there are changes to isp1301_omap (available in at least the linux-omap tree) which make it work on a H3 board with an OMAP-1710. Those changes unfortunately break the OMAP-1611 support ... and I have no idea what issues show up on other OMAPs. In short, depending on what silicion you're working with, and what external transceiver, you may need to put a bit of time into things to make OTG work on your particular board. - Dave ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
