When reporting a problem with hardware detection, you should report the bug against the kernel. Beginning with the Hardy release, all kernel bugs should be reported against the '''linux''' kernel source package.

Also, all reports should contain the following information. Please be sure to '''attach''' these files to the bug report.

 * uname -a > uname-a.log
 * cat /proc/version_signature > proc_version_signature.log
 * sudo lspci -vvnn > lspci-vvnn.log (those are 2 v's not a w)
 * dmesg > dmesg.log

If the system is not correctly detecting a USB device, also '''attach''' the output of:

 * lsusb > lsusb.log
