|Have you tried with 2.4.21 (not pre4), if not start there then try 2.4.22 and see if it works. The USB-layer in 2.4 around that time being was pretty immature IIRC.|

I am working on an AU1100 system, using a 2.4.21-pre4 kernel. Filesystem
is jffs2, uclibc libraries.
I have a couple of problems with USB flash disk handling:
1) it seems that my system does not "see" disks larger than 512 MB. 1GB
disks or more cannot be mounted. This is becoming a problem because
512MB disks are going out of the market.
2) Given two flash disks of different sizes (for example: one 128 MB,
one 512 MB), if I mount/umount one of them -> I cannot then mount the
other and vice versa.
- - mount the 128 MB one, then umount. Try to mount the 512MB ->fail.
- - reset the device
- - mount the 512MB device, ok. Umount. Try to mount the 128MB -> fail.
Disks are vfat formatted ; did not try with other filesystem types.
Tried to use a 2.6.x kernel and no problem ; I am planning to switch all
to 2.6.x kernel, but in this moment for me is better (if possible)
fixing this problem, because I have a number of applications and drivers
running on 2.4.21 and the switching to 2.6.x means revising and
re-testing a lot of things.
Back to 2.4.21...
If I try to dmesg I see a "Partition check:" message missing when I put
in the second disk ; I am investigating on this (maybe some piece of
software is called checking for partitions on the first disk but is not
called again when I change disk type).
Any suggestions are welcome,
