USB mouse/keyboard not working

Should have reported this ages ago. I’m using the flashed version of 5.14 on my developer-model Iyonix. Usually after power on or ctrl-break, one or both of mouse and keyboard don’t work until I unplug and plug them back in. I haven’t tried 5.15 softload to see this helps.

This may or may not be the problem, but while looking through the CVS logs today for an unrelated issue I found some notes about how USB_PORT_RESET_DELAY was decreased to fix the Chicony keyboards that are shipped with some Iyonixes. Apparently you can use the USB$PortResetDelay system variable to tweak the value – it might be that the default value built into the ROM image doesn’t work for your keyboard & mouse, but a value that gets set later on in the boot sequence does work. Or perhaps it’s the value built into the HAL, since the HAL has its own cut-down USB driver to do the keyboard scan at boot.
