Two parts answer:

1) Yes, it is a firmware bug and you are not supposed to be able to use 12dB in USB-in (I assume your "16dB" is a typo). It should have automatically switch to 6dB gain with USB-in. However, because FiiO didn't implement the firmware tight enough, you are able to fool the system and select the 12dB gain.

2) The reason FiiO doesn't want the user to use 12dB gain is because that is too high a gain for USB mode. It will just clip the amp section and result in distortion.

A very late Thank You for your detailed answer! :) Though I don't hear the E17 clip when set to +12db (it wasn't typo earlier it's really me thinking wrong since I don't have my E17 with me when I asked the question) using USB mode. I guess I'll have to listen again very carefully for any possible clippings..

Ok... so I've tried using it without the Driver/ ASIO Program and it works relatively well.  I still get the occasional hiccup where the sound disappears while the audio levels change in my Sound/Speaker/Volume thing in my notification bar but it is much better than a BSOD.  
 
Right now, my workaround is to turn off the amp and DAC and turn it back to get audio again.  If anyone has any tips about getting around this little hiccup, it'd be much appreciated.  If not, thanks for everyone's help!

Recently my e17 / e9 combo has been giving me trouble.  I have to prop the e17 forward in the dock to get USB lock and re-dock it a few times to get both channels working.  Has anyone heard of similar problems?  I searched but didn't come across anything.

The FiiO dock connector is not up to Apple Dock quality in my opinion, one has to be really careful with it for sure. It really sounds to me like a connector problem, try my sloppy connector fit fix and see if it helps.

Other than that contact James from FiiO here on Head-Fi and let him know about it.
Good Luck!

  If I was getting the E09k/E17 combo but could only get it one piece at a time, so I'd have one for a month or 2 without the other, would I be best getting the E17 first?

Yes.

Bought the ALPEN a while ago, waiting for the Mont Blanc to come.

Just noticed this.
 
When you have the bypass switch on the E17 in the down position (so volume is controlled by the E9K) why is it louder than when you have the bypass switch in the up position? Volume is maxed out at 60 but the down position is still louder.
 
Is it because the gain is turned up when you have it in the down position? When the switch is in the up position, I have the gain setting set to 0 on the E17. Does it automatically raise the gain when you put the switch in the down position? (I'm assuming it's raising the gain to 6 by itself, even though the screen says 0).

It bypasses all the onboard volume & EQ controls so you get line out levels to the E09K.

Try setting your gain to 6 and see if the output is the same with the switch up and volume 60.

i notice today that when i use the E17 with headphones, i can hear a noise that is similar to 8/16 bit video game (something from like Asteroids from example). Happens a few times in a song; never notice this with speakers w/line out. I tried different headphones and it still occurs.
 
Going to try different usb cable/port, different music player, and OS.
 
BTW I also  get BSOD related to asio on windows 7 too. Guess asio doesn't like my computer.

Remove the ASIO drivers you don't need them. Also is there a cell phone close by? If so move it to another room and see if the noise goes away.
