UPDATE: this has been updated as per the developer's (Oliver Haag) recommendations (see first comment)
Original post:
I wanted to get Hantek DSO-2250 USB running on debian. I first tried openhantek 0.2.0 but it doesn't support the DSO-2250, so I ended up using the development version. I had to get the configure and Makefile.in files from another source though (see below).
I finally got the scope to work as shown below -- I primarily needed it for some work on NMR probes I did two years ago, but better late than never.

Before installing anything, on plugging in the oscilloscope we get:

While tempting (the ID shows up as 04b4 above), do NOT change the part marked in red in 90-hantek.rules since changing it requires you to run as root. It works fine as user if you leave it alone.

Plug in your oscilloscope:

At this point the light on the oscilloscope was blinking red.

Check the 'show spectrum' thingy (I'm running this with the probe on CH1 connected to the square wave cal at the back of the scope).
Done.
