Red Hat Bugzilla – Bug 450493
Can't write to USB memory programmatically (but can from the console)
Last modified: 2008-07-03 11:56:15 EDT
I have a standard Fedora 8 system which I keep up to date whenever the update
manager says there are updates. When I updated last I got a new kernel:
When I run my custom backup program it fails to write to my USB memory sticks
giving "Operation not permitted" error messages.
When I use cp at the console I can copy the backup files to my USB memory sticks
without any problems.
If I reboot and use the old kernel, 126.96.36.199-92.fc8, everything works fine.
(PS I don't think it is an SELinux problem. I have that set to permissive but
retried with it disabled and neither setting made a difference.)

I don't know how to get that kernel. Here's what yum says:
: yum list "kernel*"

I just got an update message and updated my kernel so now I have 220.127.116.11-40.fc8.
After rebooting I got the same scary USB messages (which I don't get with
2.6.24* but did get with 18.104.22.168*):
hub 1-0:1.0: unable to enumerate USB device on port 3
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 8
but despite those messages, everything now seems to work fine!
