I can confirm that the failure of the Debian 12 Kirkwood ARMEL installer to enumerate USB drives on my Ionics-EMS Nimbus 100 is a Linux kernel bug. I found another, more recent, Linux kernel at https://forum.doozan.com/read.php?2,12096 and booted it. Though it also does not have UBIFS support built into the kernel (so it fails to mount my ubi0:rootfs), I can see that when it boots, my USB LEXAR FIREFLY drive is enumerated:
[ 6.189582][ T8] usb 1-1: new high-speed USB device number 2 using orion-ehci [ 6.409884][ T8] usb 1-1: New USB device found, idVendor=05dc, idProduct=a701, bcdDevice=11.00 [ 6.418850][ T8] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 6.439428][ T8] usb 1-1: Product: JD FIREFLY [ 6.444099][ T8] usb 1-1: Manufacturer: LEXAR [ 6.448750][ T8] usb 1-1: SerialNumber: 1069A704000328051007 [ 6.470773][ T8] usb-storage 1-1:1.0: USB Mass Storage device detected [ 6.490204][ T8] scsi host0: usb-storage 1-1:1.0 [ 8.642833][ T8] usb 1-1: USB disconnect, device number 2 See my post on the Doozan forum at https://forum.doozan.com/read.php?2,138142. Please update the Debian 12 Kirkwood ARMEL kernel. And, if you would, please include UBIFS support in the kernel to allow for an eMMC UBIFS rootfs.
