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.
