Steps to reproduce:
1. boot kernel with parameters "rw root=/dev/sdb1 log_buf_len=1M init=/bin/
bash"
2. modprobe -k uhci_hcd
3. modprobe -k usbhid
Current result in case of 2.6.27: USB keyboard starts to work
Current result in case of 2.6.28: USB keyboard does not work

Is it input/HID, or USB?

The same USB keyboard is working correctly with Clevo D410J laptop with 2.6.28,
so I guess it might be an USB problem.

Why are you doing the modprobe by hand? Doesn't the module get autoloaded 
properly?

The modules were not autoloaded. This is a minimal test environment with only
a few binaries in the root directory. Is the "modprobe" binary enough for
autoloading?

I just was able to try the situation: the modules are not autoloaded.

Anyway, in 2.6.28, this keyboard is driven by specialized 'hid-bright' 
driver. Does modprobing it by hand fix the problem?

I'll try the hid-bright module as soon as my laptop gets repaired.

Loading the hid-bright module handles the USB keyboard properly.
But it is still not clear for me why this module is not autoloaded?
