I dunno, but it seems that the spec is pretty clear about setting caps when you’re above state 4, pretty much requires cap_extendedcaps. If your device doesn’t support cap_extendedcaps/get or doesn’t like when you try to send cap_extendedcaps/set you are probably hosed.
If you are always changing the setting for the second page, couldn’t you just request a single page from the device then close your session and open a new session for the second|next page?
