Hi there ...
My name is Thomas I'm trying to use an USB-headset on a meshcube, a MIPS
based embedded device (http://meshcube.org/meshwiki/). If I plug in the
headset while running 2.4.27 a led on the headset turns on. If I do the
same with 2.6.12-rc6 (latest MIPS CVS) nothing happens. I also tried an
optical USB-mouse with the same result. All these tests are done with
Debian GNU/Linux Sarge 3.1 on NFS-root.
My kernelconfig is:
$ sed '/^#/d;/USB/!d' .config
CONFIG_SND_USB_AUDIO=m
CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI_HCD=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
kernel boot messages are:
usbcore: registered new driver usbfs
usbcore: registered new driver hub

As far as I can see USB drivers are working correctly, hardware is
detected but the USB is not working. Any hints?
TIA
Thomas
