Hi all,
linux kernel 2.4.19-pre7
I have problems with a creative NOMAD jukebox.
When I do a command, it disconnects/reconnects after each access.
- the command uses /proc/bus/usb/001/002 the first time
- the the 002 disconnects and reappears on 003
- the command then works again on 003
- etc
Also, how can I access 002 ... from a regular user (without chmod under ROOT,
...)
Dmesg out attached (usb debug in kernel active)
