Sorry to reply to this thread again so quickly, but I'm seeing more
weirdness. After a few open(fd),close(fd) calls on the device it's no
longer responsive. There are no problems opening the device anymore,
but dmesg gives me stuff like this when I try talking to the device:

Physical reconnection doesn't alleviate this problem (which is odd
because physically disconnecting the device turns it off as well). I
have to restart linux to use the device again.
