<p>I don't have any nvme drives. The SSDs I have are sata.</p>
<p>Thanks for your reply. I ordered another of the same model
adapter I have that works. I'll use it when it arrives.<br>

have a Raspberry Pi4 and I've had trouble with some adapters
for some <br>
sata ssds I've tried using with it. I have several usb3
adapters that <br>
don't support uasp. When I try using one, the speeds are slow
and I get <br>
lots of errors. I looked this up online and everything I saw
about it <br>
said that some usb3 ssd adapters don't support uasp and a
system trying <br>
to use it will get slow speeds and lots of errors. Some of the
stuff I <br>
read says how to get the manufacturer and model id numbers and
put them <br>
in /boot/firmware/cmdline.txt so the system will not try using
uasp with <br>
those devices. In the cmdline.txt file on my Pi4, I have the
following <br>
at the front of cmdline.txt:<br>
<br>
usb-storage-quirks-152d:0578:u (152d:0578 is the manufacturer
and <br>
device numbers for the device in question.)<br>
<br>
This is supposed to tell the system not to use uasp on the
specified <br>
device. I tried that, and rebooted the pi, but still have the
problem. <br>
The only way I got it working was to plug the second drive
into a usb2 <br>
port. It's a bit slower, but works.<br>
<br>
Here it told how to identify the device and how to modify
cmdline.txt to <br>
tell the system not to use uasp with the device<br>

<br>
The cmdline.txt file starts with
usb-storage-quirks-152d:0578:u<br>
<br>
Typing lsusb identifies the device.<br>
<br>
$ lsusb<br>
Bus 002 Device 002: ID 14b0:0206 StarTech.com Ltd. Vi550 S3
This one <br>
works. The drive the pi boots from is connected to it.<br>
<br>
Bus 001 Device 003: ID 152d:0578 JMicron Technology Corp. /
JMicron USA <br>
Technology Corp. JMS578 SATA 6Gb/s This is the one I'm having
trouble with.<br>
<br>
It does not work without lots of errors. I only got it working
by <br>
putting it in a usb2 port. Is there any way to test whether
or not a <br>
device supports uasp?<br>
<br>
Thanks for any help you can send my way.<br>
