Hello drvctl can be used to detach a device using option -d, this is quite straightforward. What is rather cryptic is how to use it to scan the bus and attach a previously detached device.
This page documents how to scan a SATA bus using for instance drvctl -a ata_hl -r atabus3 https://wiki.netbsd.org/users/mlelstv/using-large-disks/ What is the equivalent of ata_hl to scan an USB bus? And what busdevice should be used? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz m...@netbsd.org
