For now we only support USB <3.0 devices, as we don't support streams. We also don't leverage the benefits of UAS, as we pretend to have a queue depth of 1, ie are single threaded. To test this driver, you can use the following command: ``` SERENITY_BOOT_DRIVE=usb-uas Meta/serenity.sh run x86_64 Clang ```
