UASP?

Post by southpaw32 »

I bought a USB adapter that supposed to support UASP, but it's only showing up as a USB device.

It's from a fresh install. Is there something I need to do to enable UASP?

lsusb -t

Some adapters are just crap. The linux kernel contains a blacklist of their USB-IDs and disables the uasp feature. Check your boot logs.

Thanks for the info.

Follow-up question.... If I get a new/better adapter, can I just swap it out, or will it require a full reinstall?
(backup/restore?)

If you do not boot from the USB device, there's no need for a new install. Just swap the adapters.

If it is your booting device, I'm not quite sure. Just give it a try.
