I have bought and used a 2204a some time ago but due to a libmono
problem I (and a lot of others) can not use my scope anymore.
usbtest finds the 2204a scope :
Pico USB device found: /dev/bus/usb/005/002
- It belongs to root (which is not you) who has permissions rw-
- The members of group pico (which you are in) have permissions rw-
- Everyone else has permissions r--
- You can write to this device and so will be able to use it.
I have compiled the ps2000con program and run it :
roelofh@castle:~$ /opt/picoscope/bin/ps2000con
PS2000 driver example program
Version 1.0
Opening the device...

I am using a Debian 8.2 testing with Mate desktop fully up to date install.
I'm having a similar issue that has occurred since upgrading to Ubuntu 16.04LTS. I have also performed a new install of 16.04 as well, then followed the posted instructions (https://www.picotech.com/downloads/linux) for installing the picoscope software and drivers as I have had success with in Ubuntu 15.04 and 14.04, however the picoscope application cannot find the picoscope device (2205a): the "No Device Found" dialog box appears.
The USB device is being recognized by the operating system, however:
$lsusb
....
Bus 003 Device 014: ID 0ce9:1007 Pico Technology PicoScope 2000 series PC Oscilloscope
....
The next thing to do is wait for picotech to release a version that
does not break down due to libmono. I am hoping for a VERY soon
release.
Did you try the usbtest and usb2000con programs ?
I am not going to backport, or whatever it is called, an old version
of libmono to get picoscope working. But in the meantime I find
myself without my useful tool.
