Just be sure you have sshd up and running before switching the hub when
using the diNovo Keyboard. ;)
This is also the reason for putting one of those stupid disclaimers into
the source.

I don't know if Logitech knows how to switch back. ;)
At least I've send them a bug report, that the widcomm-stack should switch
back to usb-mode when deinstalling the stack.
I've discovered that because I've got the answer "reinstall all" 2 times
for a problem. But deinstalling the stack leaves me with a box, I could
only reset using a hw-switch, which isn't that fine. The problem I now
have, is to explain this to help desk. The first time they didn't
understand what I mean. ;)
When they will fix that, I will try to log the usb-communication while
deinstalling the stack, which should give me the correct sequence of
reports for switching back.
Regards,
Alexander

OK, thanks for the info. And good luck in your search.

No. I think it is possible, but at the moment we don't understand how
the Logitech protocol works. I have some written notes about it on my
desktop, because they also use the same protocol framework for driving
the display of the mediapad. But I haven't found the time to setup a
webpage about it.

one of our device has an ID of 0x046d:0xc703. Can you add it to the
hid2hci.c file in the CVS ? I have tested it, and it works OK.
One question: I can't switch back to USB mode. Is this not supported at
this time ?
Good day.

This is something I doesn't understand too. Either the Linux-USB stack is
missing the disconnect, or a 'magic' report in the switch-sequence for
finally disabling the usb-hid-device is missing.
Using Windows it seems the usb-hid-dev is removed after starting the
bluetooth-stack. I will check my win-logs if I could find another report
which could do this.

Alexander

I modified the hid2hci program to support switching of the Logitech
Bluetooth wireless hub. Code is in CVS now and it should also support
the Apple devices with HID proxy out of the box.
A little bit weird is that the HID device 046d:c704 is still present
after switching.

Marcel
