What exactly do you mean by 'not recognised'? Is the USB enclosure not detected at all, or does it just not present an sd device, for example connecting as ugen instead? The output of usbdevs -vv would be helpful if it's recognised at all. > Is there another eclosure that is known to work with this M.2 SSD? Various enclosures work, anything that presents as a regular usb mass storage device would be expected to work. If you want a JMicron chipset based device, I can confirm that the Icy Box IB-1807MT-C31 works with OpenBSD, (and has a write-protect switch which may be useful depending on your application). The Sabrent EC-SNVE also works, (but lacks a write-protect switch). This uses a Realtek chipset.
