Almost nothing, an estimated 3310 sats a month with one Compac F miner at 300GH/s. And that's assuming the pool allows you to join them.
If you want to have a small but reasonable constant payout with a silent miner, then have a look at the Apollo BTC. It can produce around 3TH/s, so 10 times more than one Compac F.
Based on what you've described here I think the Apollo is the perfect miner for you. It's quiet, looks great, and produces a reasonable hashrate.
Not a good choice because Apollo can pull 200w while Compac F is around 9w. So Apollo consumes more power than the USB stick not a good choice for a 9 cents rate unless he doesn't care about the power consumption.
For clarification, if you have 10 Compac F you can also get 3th/s with around 90w which consumes less power than Apollo.
I just want to add this calculator below with a breakeven analysis to estimate the ROI of your unit.
