15 inch LCD Studio Display and YDL4

[Henry A. Leinhos]

Hi,

I've mentioned this in a previous post, but I'll try to be more specific 
regarding my problem.

I've got a 466 MHz G4 5-slot Digital Audio PowerMac with 640 MB ram 
installed.
Video is  Rage128 Pro PF (AGP) [chip rev 0x1] 16M 128-bit SDR SGRAM  
(from dmesg).

I've also got a 15-inch LCD Studio Display attached with an ADC connector.

The monitor works fine with YDL3, and has a USB HID-monitor device (the 
control interface) as well as a USB hub device, as can be seen in 
/proc/bus/usb/devices:

My problem is that the YDL4 installer hangs at the /sbin/loader step, 
but installs fine if I use a VGA Monitor the install goes fine.  I can 
reboot into YDL4 with the VGA monitor, but the system hangs when it 
tries to mount the usbfs.

Anyone else out there with an Apple LCD studio display?

Thanks,
Henry
