dear BBB experts---let's say that I want to use my BBB's client USB port
for a USB gadget device, but *not* as a USB mass storage device. think
char buf[16];
while (1) {
fread(buf, 16, 1, fusbin);
for (int i=1; i<16, ++i) buf[i]=buf[i]+buf[i-1]; // real-life, most
stuff here.
fwrite(buf, 16, 1, fusbout);
}
16-bit byte blocks are probably too small for USB block transfers.
USB 2 should have throughput of about 480MBps best-case. Can the USB
gadget device in single-byte mode reliably hit 1/1MBps (or about
100/100KByte/sec upstream downstream)? or am I limited to the old 115200
baud rate, which is only about 1/10 of this speed. Any experiences?
