I am unaware of any 2-channel integrated amps that have multiple optical inputs and a usb input. There are a few integrated amps out there that have either one coax or optical input or a usb input, but I'm not familiar with any that have both.
If you think about it, in general, high quality 2-channel audio pieces typically only house one function within the box, i.e. pre-amp, amp, DAC, cd player, etc. An integrated amp places two functions inside one box (pre-amp, amp). In order to have optical inputs and a usb input, you would be placing yet another function (DAC) inside the same box. Digital technology changes rapidly, so you would possibly be obsoleting a product by putting the DAC function into the same box with the pre-amp and amp. I don't think many high-end audio manufactures are going to go that route.
In general, multiple optical inputs (and potentially USB inputs) are still in the realm of the HT receiver, not high end integrated amplifiers.
YMMV, IMHO, I'm not familiar with every audio product ever made, etc., etc., etc........
