When the sa1110 system goes to sleep I get a message " usb-uhci.c: interrupt, status 2, frame# 1790 " on the host side . This messages keep on comming on the host side even after the sa1110 system wakes up from sleep. But each time the frame no: will be different. The sa1110 spec says that if sa1110 goes to sleep the usb slave registers get reset and the device does not respond to its host assigned address. So is there any thing could be done on the usb slave side (from the usb slave driver on sa1110) so that it could be assiged a new address .
