Bug#825171: [powerpc] Some USB device are not (easily) supported for d-i

[Mathieu Malaterre <malat@debian.org>]

Package: debian-installer
Severity: wishlist

I have an old USB key which does not seems to be easily supported by
d-i (stretch alpha 6 tested).

USB key preparation:

$ wget http://cdimage.debian.org/cdimage/stretch_di_alpha6/powerpc/iso-cd/debian-stretch-DI-alpha6-powerpc-netinst.iso
$ sudo dd if=debian-stretch-DI-alpha6-powerpc-netinst.iso of=/dev/sdb bs=4M
$ sudo sync

Unplug USB key, plug into Mac Mini G4. Boot. Press Ctrl+Cmd+o+f. Start yaboot:

> boot usb0/disk@1:2,\\yaboot

Then use 'install32'

After a couple of step, d-i should fail the 'find CDROM' step.

Workaround:

1. Physically unplug the USB key.
2. Replug the USB key
3. Go to Screen 2 (Ctrl+2)
4. mkdir /tmp/bla
5. mount /dev/sdb /tmp/bla
6. umount /tmp/bla

Then go back to main screen (Ctrl+1) the CDROM can be found again !

Using a newer USB key I cannot reproduce this bug. I have been running
dozens of `badblocks` to check the old key and it seems very
reliable...
