[Xen-devel] [PATCH][14/17] USB virt 2.6 split driver---USB interdomain protocol
This patch defines the USB interdomain protocol which consists of a number of transactions and a message sent using the xenidc_endpoint code. This protocol is a direct translation of the 2.4 protocol and uses polling for device detection. There is an issue with queued commands during error recovery. The queued commands need to be stalled during the unlink process but currently they are not. Both the polling and the queued commands issues need to be fixed. This may affect the protocol. The current protocol is good enough for read only access to USB devices and works for read-write access but is not safe for write access during error recovery.
