USB2 can do 10MSPS easy, but in my experience small SBCs like the Raspberry Pi struggle to keep up with this rate at the CPU. Might be more practical with the newer models, but I gave up on an RPi 3 with a 10MSPS SDR because it was excessively dropping samples at around the 5MSPS point... so it's possible that 4MSPS is approaching the limit of the CPU, at least for a given level of optimization of the software tools (I was mostly just sending out I/Q samples over the network).
