Hi
Is there anything I can do to flush all usb / usb storage buffers to my
compact flash ?
At the moment I have to rmmod usb-storage && rmmod usb-uhci && modprobe
usb-uhci && modprobe usb-storage to ensure all data is written
correctly, otherwise the directory structure isn't saved even after an
unmount.
Is there an application, function call, ioctl, .... which I can use,
instead of the above mentioned inconvenient way ?
Kind regards
Joseph Wenninger

Hi Joseph,
You don't mention what USB device you are using with your compact flash.
I don't have any problems with a "SanDisk Imagemate, SDDR-31" USB
CF reader: works flawlessly.
I'm using a up-to-date Red Hat 7.3 system with Red Hat kernel 2.4.18-10.
Maybe the driver(s) for your USB and/or cardreader are buggy.
greetings,
Rob van Nieuwkerk
PS: before chosing the SDDR-31 I did some extensive web-research on the
USB/CF readers available with Linux. I chose the SDDR-31 (which
can be a bit hard to get nowadays) because it seemed the device
with the least (Linux) problems.

sync(1) and then umount(8) doesn't flush everything to the device?
thanks,

Exactly. If I remount the device it looks like everything is okay, but
if I put it into my notebook instead the CF appears still empty. If I do
the module unloading before I remove the CF from the reader it works. I
don't think that it is the card reader, since it works perfectly with
Windows XP or 2000.
Just for reference I use a ML4-USB card reader/writer from Datafab. It
is a device with 4 slots (each appearing as an own device) for
CF,SM,SD,MS
Kind regards

eject sda|whichever device it is, maybe?
Works here with my SM/CF reader.
