#24485 — Connecting to an embedded Linux device over USB

I have a piece of hardware (drum machine) which I know runs a version of 
Busybox on an Intel Atom platform, I think.

It appears to have 256 megs of RAM and a gig of internal Flash storage.

I'm trying to figure out what the best way to hopefully ssh into the 
device and gain root would be, as it seems there's a corrupted file in 
the Flash storage that's causing it to crash repeatedly when using its 
custom user file manager. I've tried doing a factory reset and 
reinstalling the latest OS from an SD card - it has both types of USB 
ports and two SD card slots to connect external storage - but apparently 
the factory reset didn't wipe the user partition of the Flash and the 
corrupted file remains.

When connected via USB to a Linux PC it appears under "lshw" as:

*-usb:2
                       description: Audio device
                       product: Beat Thang
                       vendor: BKE, LLC
                       physical id: 3
                       bus info: usb@1:3.3
                       version: 2.25
                       capabilities: usb-2.00 audio-control
                       configuration: driver=snd-usb-audio 
maxpower=500mA speed=480Mbit/s


When Googling for information a Reddit user claimed to be able to ssh 
into the and examine the hardware capabilities and file system, but I 
wasn't able to contact him.

Any advice on where to begin?

Well, what happens when you try to ssh to it?

 $ ssh -v root@<drum-machine's-ip-address goes here>

Not sure how to find its IP address, if it has one. LSHW wasn't giving 
up the info, at least.

How is it connected to the network? (RJ45/Ethernet, Wifi, etc.)

USB is the only thing I have to work with...

According to lshw, it's a USB audio device.

You can't ssh to USB audio devices. In order to ssh to it, it needs a
network connection.  There is such a think as a USB network
connection, but what you've got doesn't appear to have one.

Before you can ssh to it, you need to figure out how to get it
connected to your local network.  Perhaps there are optional Ethernet
or Wifi add-ons?

How are you (attempting to) access it's "custom user file manager"?
Does the device let you plug a USB serial port adapter into the
USB port?  Or, a NIC?

Take the lid off and look for a header that might have a serial port on it.
It's probably be a 3.3v port that you can attach a USB-serial adaptor to.

Also look out for any other internal ports that could be useful.

Thanks, I have a USB to TTL serial cable so I'll give that a shot
