I have a Centos 5 machine which I've just compiled the 3.10.4 kernel
on (remembering to set CONFIG_SYSFS_DEPRECATED) because I needed new
rtlwifi drivers for my rtl8192cu device.
So far, so good. It seems to work.
Except /proc/bus/usb doesn't exist anymore. USB_DEVICEFS has been
removed. An older kernel (3.2.9) says
Usbfs entries are files and not character devices; usbfs can't
handle Access Control Lists (ACL) which are the default way to
grant access to USB devices for untrusted users of a desktop
system.
The usbfs functionality is replaced by real device-nodes managed by
udev. These nodes lived in /dev/bus/usb and are used by libusb.
Has anyone got udev on C5 working with this new kernel so my USB
devices show?
(It's not causing me any real issues, other than "lsusb" nor
working;
just curious!)

There could be numerous dependencies to sort out as to why this isn't working such as the interfaces from lsusb into the newer kernel. Essentially, you're on your own buddy. ;) -- James A.

They have ready-made and compatible 3.0.88 kernel, but they also have kmod packaged drivers for stock kernels. Just go to http://elrepo.org/tiki/DeviceIDs and check for vendor:device ID pairing that lspci command will show for your rtl8192cu device. Btw, RHEL/CentOS kernel is much more advanced then vanilla kernel of the same numbering because Red Hat backports latest drivers to their kernel. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant
