I finally got 5 USB keyboards together along with 2 hubs. I
daisy-chained the hubs and connected 1 keyboard to the hub that is on
the notebook computer USB port, then I connected 4 keyboards to the
second hub. They all worked for me, meaning that I can type on all of
them and have their characters show up on my console.
I'm testing with 2.6.7-rc2. 'usbtree' output of the USB subsystem is
attached.
Yeah! 2.6.7 is a bit obsolete.
I think that Randy really meant 2.6.27-rc2.
At my end 2.6.15 support more than 4 keyboards per PC port , but mess up
input when is plugged more than 9 keyboards. 10th is capable to send
keypress events, but last pressed key will be repeated until ctrl-c .
10th keyboard disturb an auto repeat of all keyboards.
Could you please verify with any more recent kernel than 2.6.15 and report
back whether the issue is still present, please?
Also, is this bug specific to USB keyboards? i.e. if you for example plug
in USB flash sticks instead of keyboards, do they all work correctly?
Thanks,
