beyond roberts exccellent explanation, you can also use dd for byte
streams, that gives you a bit more control than cat (allowing to set
blocksize, legth or offset of what you want to capture)

sudo dd if=/dev/ttyUSB0 of=outfile.bin

(there you can for example use bs=1MB count=1 to capture exactly 1MB of
data ... or skip=1kB to cut off the first kilobyte (i.e. a header, in
case you only want the payload data) of the stream)

"man dd" has all the dirty details :)
