do the same peripherals work fine if plugged in directly to your pi? none of these ‘sound’ like hub issues, especially if it’s externally powered.
there’s a compatibility list on http://elinux.org/RPi_Powered_USB_Hubs but that’s more aimed at people powering their pis from the powered USB hub. i wouldn’t expect the hubs themselves to have issues just powering USB devices, if they are externally powered, but maybe it’s possible.
i use a belkin slim 4 port powered hub. works fine.
