usb-linux: massive read perf improvement with 3 parallel transfers
By maintaining 3 parallel usb trasfers when reading we get 2-3x more
throughput when reading. Without this the usb port is mostly just idling.
I get 23mb/s on my system compared to a clean Apple stack that gives me
17mb/s.
3 was chosen because it is simple to hard code, gives very good performance,
and have very little impact on out resource consumption.
