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!)
