I have faced problem during sis installation for particular device

You may want to sign some example applications with your devcert and see if they can install on the device. Like low-caps HelloWorldBasic, Contacts, and something "higher", like Location-related examples.

Could the developer cert you applying is not granted with capabilities the app required?

It will build targets with different capabilities for different platforms automatically because your MMP file has multi-define.So,be sure you made SIS with correct target for corresponding device.My suggestion is alting you capabilities set like below
