usb CF reader and 2.4.19

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

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.

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
