Hello Gerald,
that is not the point. The disconnection and reconnection from 'high-speed'
to 'full-speed' is performed automatically by the ehci-hcd module after the
unexpected 'fatal error', due to usb_submit_urb(isoc_urb) called by the
driver, which returns -ESHUTDOWN as error. What I would like to know is
why this happens.
Of course, the driver I am writing is not going to support full-speed at the
moment, but this is another issue...
I can test/write every patches you will propose. It's almost urgent and I
don't actually have the time to investigate the ehci_hcd internals.
Many thanks.
Regards,
Luca
