Sun Microsystems X6440 manual Windows Issues, USB devices are not recognized in RHEL

Workaround:

This issue can be resolved by following these steps:

1.Temporarily limit the memory to less than 4 GB.

This can be accomplished by physically removing RAM to reduce it to less than 4 GB.

Alternately, you can use a boot parameter to limit the memory that is used by SLES. The boot parameter is mem=nnnn, where nnnn is equal to a number less than 4000.

2.Install the latest kernel update to version 2.6.5-7.311 or newer.

After using the above method to limit the memory while the system is installed, the kernel can be updated to provide the fixes so that the full amount of memory can be used.

Information about this kernel update and how to download it is available at http://support.novell.com/techcenter/psdb/436375e56cfcb119e5e4 2c29cf234297.html.

USB devices are not recognized in RHEL 4.7

The RHEL 4.7 operating system does not recognize USB 2.0 devices. This causes the OS installations that use a USB DVD-ROM or ILOM remote KVMS device to fail. More details and a fix for this issue can be found at:

Workaround:

Either install RHEL 4.7 over a network or install the updated kernel fix from the Red Hat web site. Alternatively, you can remove the ehci-hcd.komodule from the kernel by typing the rmmod ehci_hcd command from the system prompt.
