Hi, I'm experiencing the same problem with my USB keyboard. Is PS/2 a requirement for setup? Once I get to the initial grub bootloader, my keyboard seems to lose power or something.

I have seen a thread with another user experiencing the same problem and no one has seemed to come up with an answer/solution/help.

I'm really interested in this and I would greatly appreciate it if someone could help us out with this issue

Using iDeneb 10.5.5
