I see the ONLY change in config.fex from Tronsmart stock ROM to Fantasy is:
Stock:
[dram_para]
dram_clk = 672
dram_type = 3
dram_zq = 0x003F3FDD
Fantasy:
[dram_para]
dram_clk = 600
dram_type = 3
dram_zq = 0x3B3BBB
So they lowered the over all dram clock

I cannot see that causing a USB 3 issue but might be worth a try.
Soon I will send you guys a way to change this config on the fly so we can test these changes easier.
