Does the stream do the following like the book port plus?
Music CDs (CD-DA)(External USB CD/DVD drive)

OK, if this post somehow violates list rules, please let me know so I
can never do it again!
I decided to be daring and hook my LG GSA-E50L to my Stream, since
this post indicated that the Stream reads from CD drives connected to
USB. This particular drive, which is a portable netbook-compatible
drive, has two separate connectors - a Mini USB and a power cable
connector. Included with it are two separate cables, both with USB
connectors on one end. One cable has a Mini USB, the other has a power
I hooked the power plug's USB cable to a wall-outlet iPod charger
device, and hooked the USB signal cable to my Stream's USB OTG port.
Viola... It worked! The Stream read a book from the CD drive and
copied it to the SD card!
I would definitely NEVER recommend you do this on any portable CD
drive that uses a power tap cable. These drive have a single USB port
on the C Ddrive, and the computer end has dual USB connectors. In
normal operation, you plug both connectors into two USB ports, which
connects them electrically in parallel, and provides the total of two
USB ports worth of power on the USB cable. However, if you do this on
a device like the Stream, you're instead pumping 5V at 500 mAh *into*
the stream (because it gets wired in parallel to your computer's
output power!) BAD idea. THis is what the article means by
"electrically" potentially dangerous.
The reason the GSA-E50L is safe is because it has a separate power
connector AT THE CD DRIVE END. This means the extra power feed is
separate from the main feed. So, if you're going to take this sort of
dare yourself, make sure you have a portable CD drive with *separate*
connectors for the power and USB at the CD drive itself. Also, you
should use an adapter that plugs into a wall outlet and provides USB
power, rather than using a computer's USB port for the power. This is
because the USB adapters for AC typically supply more amperage -
usually up to 1000mA, while computer ports only need supply 500mA by
the standard. Connecting two 500mA sources to the drive in parallel as
is normally done by using two USB ports provides the total 1000mA
needed by the drive, but it is still OK to feed 1000mA on the power
port and nothing on the USB side. (The Stream does provide minimal
power, but it's 100mA or even less - just enough to run the typical
USB flash drive, nothing more)
I'd suspect this would also be possible using a larger desktop-style
external CD drive. These drives are nearly always self-powered and
have a transformer that converts wall voltage to the 12v/5v needed for
a desktop sized CD drive. Again, this isolates power from signla and
should be electrically safe.
I expect that doing this is potentially warranty-voiding - especially
now that they have a product of their own that they're offering. But,
for the hacker out there who isn't afraid to void their warranty and
play with their tech, this might be a fun project to mess around with.
I'm going to play around with it more, and I suspect you can actually
create the $VR folders on a CD and have them work as expected on the
Stream, or even burn NLS DTB's to CDs and play them that way.
Again, if I violated rules, please let me know and I'll never speak of
