Can I do soft hotplugging (without physically disconnecting the device)?
# cfgadm -vl (Solaris 9 and later) # cfgadm -c disconnect usbx/y # prtconf -D The device node should no longer be listed. Refer to cfgadm_usb(1M). • On my SPARC platform, when I don’t use my device for an hour or so, and try to use it, it is not working. On SPARC platforms power management may have powered it down. Edit the file /etc/power.conf, disable autopm, and run pmconfig or reboot. • I get “Connection failure” warnings when I connect my device and it does not work. Run prtconf -D on the command prompt and check if the device enumerated. Possible workarounds are connecting the device to a USB 1.x port (system ports on most SPARC machines) or connect a USB 1.x hub and then the device to this hub. This forces the device to be managed by ohci or uhci. If users do not need USB 2.0 support, another workaround is to run the below command which disables the ehci(7D) driver: # rem_drv ehci • My Belkin Omniview KVM switch works fine on Solaris x86 but not on SPARC. We’ve seen that it work
