I am one of several engineers working in a medium-sized company, located in Denmark.
We use a dozen or so 2204 PicoScopes for various purposes, and have had no problems with these, now discontinued, oscilloscopes. I recently bought the new version, 2204A (*DV943/182*), and cannot get it to work.
Windows 7 finds the device after I connect it, and loads a driver (PicoScope 2000 series PC Oscilloscope, 2.0.4.0, 23-07-2014).
When I start PicoScope 6 (6.11.12.1692), I hear the characteristic "click" as the device is opened.
I then get the message "No suitable device found".
If I reconnect the device, PicoScope 6 shows "Opening devices..." and is stuck there.
I tested this on several other computers often working with the 2204, and I got the same result.
After reading several posts on this forum, from people who seem to have the same issue, I tried installing the beta (6.12.3.2410), as well as the SDK (PicoSDK 10.6.10 (64-bit)) to no avail.
Please advise me how I might get this to work for now, and when you expect to have this fixed.
If I can assist you with troubleshooting, please let me know.
I figured out what the problem was, and it is now solved. Maybe this information can help someone. TL;DR: I solved the problem by using the original blue USB-cable.
I connected the 2204A, and opened PicoScope 6.
Inside the trace.xml file, found in "C:\Users\XXX\AppData\Local\Pico Technology\64XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", I noticed the following lines:

After that, I connected the 2204 to compare, but to my surprise, that resulted in the same error. After I replaced the cable, both devices worked. It turns out that a standard thin 3m usb cable, does not work with either device. There was no noticeable damage on the cable.
Thankyou very much for this post.
I could not get things working until I swapped usb cables with my autel scope-then I swapped back to the blue pico cable and it now works as well?
I’ve tried the above on two PCs. Laptop and a desktop, no luck. Blue cable that came with the scope was the only one I used. This cable is blue but it looks like the USB2 cable not USB3.
What would be the safest way for providing the external power to the unit? Can I use the USB splitter connected to the external power supply or power bank?
I'm no expert, but I don't see a problem using external power, as long as you match the voltage and minimum current. It shouldn't be necessary though, so I suspect your device may be defective. I'd contact support.
