I don't think this scenario is supported by the USB spec - a single end device can only ever implement a single class driver, as identified by the device descriptor. To get multiple class drivers running behind a single USB connector, you would need to emulate a USB hub and hang the class drivers off the back of that - one per virtual USB slave device. While such a feature would be nice to have, it would need quite a bit of extra work and may require additional features which are not present on the currently supported hardware. -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
