Can you try to boot to the CFE command prompt without the Aten KVM connected, and then connect it to the above mentioned "keyboard" USB slot on the motherboard to see what message CFE provides?

Very interresting. If I do this, not only does the CFE not lock up, but I'm actually able to use the keyboard with CFE. Messages printed:
Code: Select all
USB: new device connected to bus 1 hub 1 port 1 (full speed)
USB bus 1 device 2: vendor 0409 product 005A class 09: USB Hub
USB: new device connected to bus 1 hub 2 port 4 (full speed)
USB bus 1 device 3: vendor 0557 product 8021 class 09: USB Hub
USB: new device connected to bus 1 hub 3 port 1 (low speed)
USB bus 1 device 4: vendor 046D product C505 class 03: Human-Interface Device
USBHID: Keyboard Configured.

Now, I notice that the first hub is presented as "full speed", not "high speed", so the port seems to have been forced to USB 1 mode (which is what your USB 1 hub would also do), removing the need to deal with Translators. I'm afraid I don't have any USB 1 hubs, so I can't try your workaround, but I imagine that it would work. I'll try to reclaim my Bugzilla access and take a look at the ticket.

Thanks again.


is there any way to force CFE to USB 1 MODE?
What is the "set hid" command in CFE for?
