I am dealing with problems similar to ones in this thread.
http://www.linuxquestions.org/questi...hlight=rioutil
I am assuming it is a text file they are creating.

Thought i would try this and see if it would rectify my problems with rioutil and jrioutil. My problem being I do not seem to be able to create a file (rio0) in /dev/usb. Not as user or even as root! I'm at a loss, any suggestions?

Eh, you don't create files in /dev/usb as this is the filesystem "placeholder" for a loaded device driver.

Instead you MOUNT /dev/usb to another location on the actual filesystem.

e.g.

mkdir /mnt/usb
mount /dev/usb /mnt/usb
cd /mnt/usb

Opjose, maybe you can understand what is going wrong here. Pasted below is the output from rioutil. When i use jrioutil, a gui front end, i can see all files on the usb device, I can also delete them but to try to upload it stops at 4%, and refreshes track list. So I tried it at command line and this is what I get:

It sounds like you are getting a disconnect or communication error in the USB device driver.

I can't tell you for sure.

Linux usually installs it's own USB kernel module drivers to handle usb communication.

You may be seeing a minor conflict with the loaded drivers or you may have the wrong ones loaded.

Linux can use ohci, ehci and uhci drivers and I believe it usually loads two communication protocols.

You may need to try switching drivers.

Google around a bit for more info on ohci and usb problems.
