ok...after trying 3 different flash drives and two different usb card readers,
I'm thinking USB drive support is either broken or only works w/ the specific
flash drive that comes w/ the dev kit (which I don't have).
Symptom is this:
- plug flash drive in and the system log claims it can't read the partition
table because the unit is not ready, so you can't do fdisk on
/dev/scsi/host1/bus0/target0/lun0/disc
- let it sit for a little while and watch the light on the flash drive (the
flash drives and USB readers all have lights)
- when it lights up, hit the fdisk command and it'll read the partition table
successfully
- the light stays on only for a few seconds and then turns off and you lose
read access again
This board is running kernel 2.4.26-ts11 if that matters.
Someone has to have seen this...feels like a code bug in the usb driver to me
:-P
Here are example log msgs:
