Thank you! I'll be waiting for any updates then.

@mad-jester For us under Windows we can see UASP is enabled in various programs and the performance is not BOT. Our main concern is TRIM/UNMAP which seems to be unreliably supported. We often write...

I've managed to get another system, also with certain (and possibly better) working USB3. But the symptoms are the same - "Write Data SCSI16 To HDD FAIL!!". Are you actually able to reflash your u...

@Sabrent I've found firmwares that should work, and I'll figure out the Linux part later. The problem is, none of the updater programs work for me for some reason. Which program do you use? What co...

@mad-jester We do not sell an official one currently but may replace a failure if the device is under warranty. A replacement from third party sellers with the appropriate specifications will also ...

@mad-jester The Odroid link was from a user who said he was able to flash and get TRIM working on our JMS567 hardware. There are certainly other/better sources, it was just an example in this case....

I've found only one firmware that did not say "Wrong chip". But it did say "Unable to send SCSI16". So... I guess being a different chip is not a problem, but my USB might be?.. No way, I've got a ...

I've tried to do this, but it did not work. The firmware updater has correctly identified my device as "JMS568/567/566" (but not 578!). After I select the firmware file, it shows a warning - "The ...

So it's almost definitely JMS567 - also this seems a lot like my situation (same weird identification string), so EC-UASP 's on JMS567 might be affected by the same problem (at least a few years ba...

This is actually a good question, because I foresee a possible situation when mine leaves the building too - possibly because of capacitor wear due to being plugged in all the time. Is there a way ...

@mad-jester I think we have discovered the issue. The one we opened is JMS567. By default this chipset supports UASP with an update but all our models are new enough to have that. However, TRIM see...

It may in reality be a different chip, but it does report no TRIM support - so even if it actually could support it, those commands won't (can't) be issued by the operating system. So it doesn't ma...

Then it seems like it is likely not JMS561U, despite identifying as 152d:1561 . And there is no firmware update. But is it possible to fix?.. Could you share what chipsets did you see in the ones ...

@maria mueller The official rating is 12V at 2000mA (2A) with inner/outer diameters of 2.1/5.5mm.

@mad-jester I was told no units shipped with the JMS561U. There is new firmware for the EC-UASP but not the DS-4SSD. I replied to you in the other thread that we asked the factory to update the har...

the 12V power plug left the building. What is the proper power plug to replace it with I looked online and in images saw 12V 2A power supplies. I this right? https://sabrent.com/products/EC-DFLT ...

@Jason C Cato Disregard.  I'm getting help via support email.

@Sabrent So WHICH chipsets should we be looking for in USB TREE VIEWER, if it is not JMS578??  

(I'm sorry that the discussion has switched off the original topic; I could open another discussion if it's preferable to avoid this. The reason I was looking at other enclosures is to solve a prob...

@mad-jester We opened up some units and they were not the JMS561U, despite the ID reflected in some utilities. However, we have requested that new DS-4SSDs be updated to a newer chipset that will n...
